French Onion Stuffed Meatloaf with Cheese
French Onion Meatloaf au Gratin is the ultimate comfort food mash-up. Take the best part of French Onion Soup – the rich caramelized onions and ooey, gooey cheese – stuff it inside one of the most classic recipes. Then top it with a soupy gravy and more golden brown cheese.

A Comfort Food Mash Up
Comfort comes in many forms. Oftentimes we think of doing something to treat ourselves in order to feel better. Buying a new outfit, getting a haircut, bingeing a show.
Other times it comes from doing something good for others. Knowing that we have made others happy brings us joy and satisfaction. Maybe it’s getting your kids to donate their old toys or just calling an elderly relative.
Then there are times when you can do double duty but making and savoring a favorite comfort food, but inviting someone over or doubling the recipe so you can share it with someone else.
But how about double duty squared when you combine two comfort foods into one amazing recipe!
French Onion Meatloaf Recipe
French Onion Soup au Gratin Stuffed Meatloaf definitely combines the best of two comfort foods. Just like my French Onion Stuffed Meatballs, this recipes calls for stuffing caramelized onions and gooey mozzarella cheese into another classic comfort food – MEATLOAF!
You see, stuffing cheese and onions into meatballs can get a bit tedious. So this really was a stroke of brilliance, if I do say so myself. Then covering it in a soup-inspired gravy and more cheese – you really can’t go wrong!
And if you love the flavors of French Onion Meatloaf in the winter, but can’t bear to turn on the oven in the summer, try French Onion Stuffed Burgers!
How to Make Stuffed Meatloaf
Here is a brief overview so you can see just how easy it is to make. Scroll down to the printable recipe card for the full quantities and details.
But don’t skip my PRO TIPS below!
This recipe has three main components – the caramelized onions, the meatloaf itself, and the sauce.
For the caramelized onions
You’ll need:
- Olive oil
- Onions – I like to use a sweet onion, such a a Vidalia or Maui, but any white or yellow onion will do. It should be halved and thinly sliced.
- Thyme – you can use fresh or dried
- Kosher salt and pepper
- Beef broth
- Dry red wine – you can use an inexpensive wine, but use one you would drink, not one of those bottles of cooking wine. I usually use a Cabernet Sauvignon, but Pinot Noir or Merlot would also work nicely. If you don’t cook with alcohol, substitute with additional beef broth or even Worcestershire sauce or balsamic vinegar for that depth of flavor.
To caramelize the onions, heat the oil in a skillet over medium heat, add onions, salt, and pepper and caramelize slowly. Stir frequently to avoid burning the onions. Add the remaining ingredients, then simmer until very little liquid remains.
Set aside until you are ready to ad to the meatloaf. You can even do this a day in advance and keep the onions in an airtight container in the refrigerator.
For the gravy
You’ll need:
- Beef broth
- Dry red wine – same note as above about the type of wine, though here I would substitute with more beef broth and perhaps just a splash or Worcestershire or balsamic vinegar.
- Cornstarch
- Kosher salt and pepper
You can make the sauce while the meatloaf is in the over because you only need to add it for the last bit of time in the oven.
Simply whisk ingredients together in a small saucepan, bring to a boil over medium heat, reduce to a simmer and cook until thickened. Set aside.
For the meatloaf
You’ll need:
- Lean ground beef
- Bread crumbs – for a gluten free option, you can use gluten free bread crumbs, or place certified gluten free oats in a blender or food processor and pulse a few times to form crumbs.
- Fresh parsley
- Kosher salt and pepper
- Eggs
- Mozzarella cheese – you can also substitute your favorite cheese, but I like the way the mozzarella melts in the middle and browns on top.
Preheat oven to 350°F.
In a bowl, gently combine ground beef, bread crumbs or oats, parsley, pepper, salt, and eggs with your hands.
On a piece of plastic wrap or wax paper, press the meat mixture into a 10×12-inch rectangle. Set aside some of the carmelized onions and cheese, and sprinkle the rest over the meat. Roll up like a jelly roll, and seal the ends to form into a loaf.
Place the loaf in a 9×13-inch baking dish and bake at 350°F for 45 minutes. Then pour the sauce over the meatloaf, sprinkle the reserved onions and cheese over the top, and bake for another 15-20 minutes, or until it has an internal temperature of 160°F.
BRIANNE’S TIP: A good Instant Read Thermometer is an essential kitchen tool!
Switch your oven to broil, and place under the broiler for 2-3 minutes or until the cheese is browned and bubbly.
Garnish with fresh parsley, if desired. Remove from oven and allow to rest 10 minutes before slicing and serving.

French Onion Soup au Gratin Stuffed Meatloaf
Ingredients
For the onions:
- 1 Tablespoon olive oil
- 3 onions halved and thinly sliced
- ½ Tablespoon fresh thyme or ½ teaspoon dried thyme
- 1 teaspoon kosher salt
- ½ teaspoon pepper
- ¼ cup beef broth
- ¼ cup red wine I used Gallo Family Cabernet Sauvignon, but Pinot Noir or Merlot would also work nicely
For the meatloaf:
- 2 lbs lean ground beef
- 1/2 cup bread crumbs or instant or slightly ground oats gluten free, if needed
- 2 Tablespoons minced fresh parsley
- 1 teaspoon pepper
- 1 teaspoon kosher salt
- 2 eggs lightly beaten
- 8 oz mozzarella cheese shredded, divided
- Fresh chopped parsley for garnish optional
For the sauce:
- 2 1/2 cups beef broth
- 1/2 cup red wine I used Gallo Family Cabernet Sauvignon, but Pinot Noir or Merlot would also be good
- 3 Tablespoons cornstarch
- salt & pepper to taste
Instructions
For the onions:
- Heat oil in a skillet over medium, add onions, salt & pepper, cook 15-20 minutes, stirring frequently or until caramelized.
- Add thyme, sauté for minute or two, then add the wine and beef broth.
- Reduce until very little liquid remains.
- Set aside.
For the meatloaf:
- Preheat oven to 350°F.
- In a bowl, combine ground beef, bread crumbs or oats, parsley, pepper, salt, and eggs. Gently combine with your hands until blended, but try not to overwork the meat.
- On a piece of plastic wrap or wax paper, press the meat mixture into a 10×12-inch rectangle.
- Set aside 1/2 cup shredded mozzarella cheese and 1/2 cup of the caramelized onions. Sprinkle the remaining 1 1/2 cups cheese and the caramelized onions evenly over ground beef. Roll up like a jelly roll, starting from the short end, lifting the wax paper or plastic wrap as you roll. Seal the end completely, and place seam-side down into a 9×13-inch baking pan.
- Place pan in the oven and bake for 45 minutes. While the meatloaf is baking, prepare the sauce (see below).
- Remove pan from oven, pour the sauce over the meatloaf, and sprinkle with the reserved onions nd cheese.
- Return meatloaf to oven 15-20 minutes, or until no pink remains and it reaches an internal temperature of 160°F. Place under the broiler for 2-3 minutes, or until the cheese is browned and bubbly.
- Garnish with fresh parsley, if desired. Remove from oven and allow to stand 10 minutes. Slice and serve.
For the sauce:
- Whisk ingredients together in a small saucepan, and bring to a boil over medium heat.
- Reduce to a simmer until reduced and thickened.
Enjoy!

Oh. My. Goodness. My family loves this recipe! My children and their families request this recipe when they come to visit. Who requests meatloaf!? Seriously, this is just the best recipe. Tasty and delicious.
Brianne @ Cupcakes & Kale Chips says
Yay, so glad you love it. Have you tried the meatballs version? https://cupcakesandkalechips.com/french-onion-soup-au-gratin-stuffed-meatballs/
Cindy says
Where does the French onion soup come in or are you making your own with Beth wine and noons?
Brianne Cupcakes & Kale Chips says
Hi Cindy,
There isn’t actual French onion soup in the meatballs. I mention in the post that the recipe is inspired by the flavors of the soup, with caramelized onions and cheese. 🙂
Ronda says
It’s the flavor from the carmelized onions, broth and red wine that you cook first. And the mozzarella cheese you layer on. You truly must take the time to cook the onions slowly and let them cook before you layer them on the meatloaf.
Andrea Llewellyn says
I’m on an aip-paleo diet. I can substitute yellow onions for the onions and paleo oats or bread crumbs for the bread. What has me stumped is the corn starch. I can use tapioca starch; what consistency am I aiming for so I know how much starch to use?
Brianne @ Cupcakes & Kale Chips says
I typically find that tapioca starch gets thicker than cornstarch, so I’d recommend starting with about half the amount. You aren’t looking for a super thick sauce. Just thickened enough to coat and moisten the meatloaf and not be super watery.
misty says
Great recipe!!! Did you create this?
I agree with the other commenters on the name of the wine and being better later (froze and re-heated-was even better than before).
I made changes (do you cringe when people say that)? but I was not a fan of the wine sauce with the venison substitute, so I used my fav homemade BBQ sauce and it was incredible.
Thanks so much for sharing. You’re an awesome cook!
Brianne @ Cupcakes & Kale Chips says
Yes, I did create this recipe. Thanks for the feedback and glad you made it work for you!
Ruth Justice says
I want to thank you for adding the name of the wine you use in your recipes. I don’t drink wine and when some one says use your favorite wine I’m at a lost! With your recipes I will now know what to look for when I go to the store. THANK YOU!!!!!!
Brianne Cupcakes & Kale Chips says
I’m so happy to be able to help you, Ruth! I hope you enjoy the French onion soup recipe.
Laronda says
Made this tonight – absolutely amazing!!!! There WILL be a battle over who gets the last couple pieces tomorrow…Might have to make 3 or 4 next time!!
Brianne Cupcakes & Kale Chips says
I’m so happy that you enjoyed the meatloaf recipe, Laronda. Incidentally, we usually battle over the last piece at our house, too! 😉
Lynn Hayes says
I was on Pinterest earlier today. I found one of your pins for French onion Au Gratin Stuff Meatballs. I’m unable to find the recipe for it, or for the French Onion Stuffed Meatloaf. I’ve done a search on your website, and still nothing. The pictures on Pinterest look amazing. I really want to make one or both of these. Can you help me?

Bobi Pixiley says
Thank you for telling us what TYPE of red wine you are using!! I’m not a wine expert. It drives me nuts when a recipe simply says Red Wine or White Wine. Then, I go to the store and see Syrah, Merlot, Cabernet Sauvignon or Rhine, Chardonnay, Pinot grigio and I think, Great, I could ruin this whole recipe because I don’t know what I’m doing!
This looks delicious and company worthy.
Brianne @ Cupcakes & Kale Chips says
In this particular recipe, it’s not going to make or break the recipe. As I noted, I used a Cabernet Sauvignon, but Merlot or Pinot Noir should work nicely as well if you have a bottle open. Enjoy!
Laurie says
This was a bit of work, but oh.so.yummy! Got rave reviews from the family. Served it with mashed potatoes (the sauce from the meatloaf was fabulous drizzled over the potatoes). Really enjoyed this twist on an old family fav.
Linnea says
This is THE best meatloaf I’ve ever made!! I made mine with Mondavi merlot and ground venison (thanks to the hubs awesome hunting skillz, lol) Mashed potatoes made better with the pan drippings/gravy and the rest of the bottle of wine with dinner…delish!! Looking forward to meatloaf sandwiches tomorrow! 🙂 Thank you for such a great recipe!
Helen Blank says
This was amazing! I suggest making extra onions to snack on while you finish the recipe. I had never cooked with this type of wine before. I’m hooked. Now I’m looking up other recipes with it in. I just had some leftovers warmed up from last night. Even better! Thanks for a super great recipe.
Brianne @ Cupcakes & Kale Chips says
So glad you enjoyed it! Thanks so much!
Hilary says
This was amazing!!! Made it and everyone loved it!
Debora Robinson says
Great recipe but I found that the sauce was bland, so I added about 2 tbsp. Worchester sauce and a half tsp. Liquid bouquet and let it simmer down 25 minutes prior to adding the onion and cheese on top. Made some sour cream mashed potatoes and needles to say dinner was gone, gone, gone!!!!!! Definitely a keeper for my files….. thanks for giving me an alternative for meatloaf!
Brianne @ Cupcakes & Kale Chips says
Glad you enjoyed it. Yes, I love Worcesteshire for a little extra pop of flavor!
Beverley says
oh my goodness Brianne what a great new twist on a classic recipe..thank you I love this recipe xoxo
Amy says
We finally made this for dinner tonight! And ooohhhhh, so good! Roberto said that this just might be his favorite of all your recipes!
Brianne @ Cupcakes & Kale Chips says
And easier than the meatballs, right?! Thanks 🙂

Brianne @ Cupcakes & Kale Chips says
Thank you! Hope you enjoy it!
Marlene says
My husband (aka Mr Fussy) requested meatloaf tonight, and I immediately thought of this recipe which I’d pinned. It was fabulous, and he rated it A+. I halved the recipe as it was just for us and am freezing the rest for another dinner. Definitely a keeper! Thanks, Brianne, for another winner.
Brianne @ Cupcakes & Kale Chips says
Oh yay!! So glad you enjoyed it! Yes, it does make a lot. We have a couple pieces in the freezer too!
Thao @ In Good Flavor says
That’s an amazing looking meatloaf and definitely company worthy!
Brianne @ Cupcakes & Kale Chips says
Yep, not just for Meatloaf Monday 🙂 Thanks!

Every once in a while I have an instant hit! Thanks Alice!
Dorothy at Shockingly Delicious says
I am swooning over the cheesy, oniony meatloaf. How long will it take me to get to your house for dinner? I think I have frequent flier miles I can use!
Brianne @ Cupcakes & Kale Chips says
Haha, I actually have a piece or two in the freezer!
Kayla says
This looks amazing! I’ll be making it this weekend. Any recommendations on something green to go with it?
Brianne @ Cupcakes & Kale Chips says
We had mashed cauliflower and green beans, but even a simple salad or sauteed spinach would be good.

Cindys Recipes and Writings says
You have all the good stuff in here!
Brianne @ Cupcakes & Kale Chips says
I know, right!!
[email protected] Tastes Good says
Oh my yumminess!! Brianne, this looks amazing! I don’t make meatloaf often enough. I surely need to put it back on the menu with this delicious recipe! Can’t wait to try it. Drooling….
Brianne @ Cupcakes & Kale Chips says
I don’t make it often either. I need to remedy that!
Shaina says
What a yummy way to flavorize (yes, that’s a word now) your meatloaf. French onion soup is deeeelicious!
Brianne @ Cupcakes & Kale Chips says
That is absolutely a word!
Jenni says
What an absolutely brilliant idea, Brianne! I’m so with Renee–genius! I know you guys will do great in your new place, but getting acclimated always takes awhile. We actually hosted an open house a couple of weeks after we moved in. We had snacks and asked neighbors (via the neighborhood facebook page) to swing by and say howdy. It was a nice way to break the ice. Serve this too. It wouldn’t hurt! lol =)
Brianne @ Cupcakes & Kale Chips says
Thanks so much Jenni! Facebook is such a help – I’ve already found a few local groups to start getting info about the area.
Jennie @themessybakerblog says
This recipe blew my mind. I can’t wait to try it.
Brianne @ Cupcakes & Kale Chips says
Aww, thanks so much Jennie!
Tammi @Momma's Meals says
What a fabulous idea! Great way to change up that regular old meatloaf recipe!
Brianne @ Cupcakes & Kale Chips says
Love switching up a classic dish!
Linda | Brunch with Joy says
Bug is super cute and you’re totally blessed, Brianne. 🙂 Your french onion soup meatloaf looks so delish that I feel like having this for breakfast.
Brianne @ Cupcakes & Kale Chips says
Thanks Joy! He can be a typical difficult 4 year old sometimes, but he has a heart of gold.
Family Foodie says
You have outdone yourself with this recipe! Wow! Amazing.
Brianne @ Cupcakes & Kale Chips says
Thanks Isabel! Definitely put some heart into this one!
smalltowngirl says
Oh my goodness! This looks amazing!! I can’t wait to try it! Looks incredible! Can I use anymore exclamation points!?!? Apparently yes. Well done!!!
Brianne @ Cupcakes & Kale Chips says
Hahaha!!
Jennifer @ Peanut Butter and Peppers says
I have to admit, that is probably the best looking meatloaf i have ever seen.
Brianne @ Cupcakes & Kale Chips says
Hahaha, thanks!!
Nichole says
This looks comforting, cheesy, an SO good. I need to make this for sure!
Brianne @ Cupcakes & Kale Chips says
Cheesy is always good!
Katie says
How awesome that The Bug is so willing to donate to those in need! So so sweet that he is getting into the spirit of things at an early age. We moved about every 2 years when I was a kid, so donating/giving away items became second nature, and it was a really good feeling (and a bit freeing too). It’s kind of funny – when we moved from Michigan to Wisconsin, I gave my bike to a friend who didn’t have one…and I somehow have never bought another one for 15+ years. Oops!
Brianne @ Cupcakes & Kale Chips says
It was very sweet of him. It is freeing to be letting go of stuff we don’t need and know that we are helping others.
Liz says
Cheesey, stuffed meatloaf???? I’d be all over this! And your Bug sounds like such a sweet boy. You’ve done well!!!
Brianne @ Cupcakes & Kale Chips says
How can you go wrong! And with my boys, all I can say is I try to do my best.
Renee says
Genius recipe Brianne – simply GENIUS!! Got. To. Have. It. and soon.
Brianne @ Cupcakes & Kale Chips says
Thank you, Renee! I’m ready to pull the leftovers out of the freezer!!
