Keto Shepherd’s Pie – Healthy Comfort Food

As busy parents, I know we all face a lot of the same challenges.

We want to put a healthy dinner on the table that our kids will actually eat, even on busy weeknights. Maybe we are trying to watch carbs for ourselves, but don’t want to make different meals for every member of the family.

Someone in the house might have a food allergy in the house, like me with my gluten intolerance. But again, I don’t have time to be a short-order cook with a separate order for each of us. And it never hurts to sneak some extra veggies into those kiddos.

That’s why I was inspired to take a classic comfort food I know my family likes, and turn it into something they might actually love even more than the original.

Why Cauliflower Shepherd’s Pie?

My Traditional Shepherd’s Pie recipe is always a hit. Sometimes, though, I’d still like to indulge in comfort food, but don’t want it to weigh me down.

Surprisingly, mashed cauliflower is actually a bigger hit in my house than mashed potatoes. Especially when I make loaded mashed cauliflower with bacon or a cheesy mashed cauliflower casserole.

So it was time to take the classic and lighten it up a little. And, as I said, a few extra veggies never hurt anyone.

What is Shepherd’s Pie?

Traditional shepherd’s pie is typically a casserole made with a mixture of minced meat, vegetables, and gravy topped with fluffy mashed potatoes. Shepherd’s pie with ground lamb is the most classic way to make the dish since a shepherd raises lambs. 

However, since ground beef is typically more common and preferred in the United States, that is what I use in my Shepherd’s Pie. This is often called Cottage Pie as well.

Keto Shepherd’s Pie Recipe

A healthy Shepherd’s Pie with cauliflower mash instead of the usual mashed potatoes turns the classic dish into a low carb recipe.

This easy dinner is total comfort food, but it is lighter and packs in the veggies. The ultimate family meal that is easy to make and will be devoured by everyone. 

What do you need to make Shepherd’s Pie?

A few simple swaps and adjustments from my original recipe cuts the carbs from over 30 grams per serving to about 11 grams per serving. 

  • Cauliflower – steamed and mashed, this replaces the traditional potatoes.
  • Greek yogurt – makes the mashed cauliflower creamy without excess liquid like milk.
  • Egg – helps to bind the cauliflower mash so it isn’t too runny.
  • Cheddar cheese
  • Ground beef
  • Onion
  • Garlic
  • Mushrooms and green beans – a lower-carb blend of vegetables compared to the frozen mixed veggies consisting of carrots, peas, green beans, and corn in the original recipe. The mushrooms also add that umami flavor that may be lost from decreasing some of the other ingredients.
  • Beef broth
  • Tomato paste – reduced from the original recipe, and can even be cut further to make this dish truly keto-friendly.
  • Worcestershire sauce – reduced from the original recipe, and can be replaced with coconut aminos to make this dish truly keto-friendly.
  • Salt and pepper

BRIANNE RECOMMENDS:

Besides the list of ingredients above, there are a few other things that will make this recipe quick, easy, and absolutely perfect.

  • Steamer basket or large pot with steamer insert – steaming is best for the cauliflower, as it will absorb too much moisture if you boil it, and then it will be too runny.
  • Baking dish – you’ll need to bake it in a heatproof oven-safe glass or ceramic baking dish. I prefer to use a 1.5-quart ceramic casserole dish, as it fills it right to the top. You can use a larger oval dish or even a rectangular glass baking pan. Something in the 1.5-2.5 quart range will work the best.
  • Food processor or blender – either will work for pureeing the cauliflower mash, but if you use a blender, I’d recommend one of the high-powered blenders. A regular blender usually needs more liquid in order to puree things smoothly, whereas you can get by with less in a high-powered blender. With either the food processor or blender, you’ll likely have to scrape down the sides a couple of times.

RECIPE PRO TIPS

  • After the cauliflower is steamed and tender, remove the steamer basket from the pan and let some of the excess moisture evaporate off of the cauliflower. This will keep the cauliflower mash from being too runny.
  • I use frozen green beans to save time. You can use fresh, but you may want to steam them slightly before adding to the ground beef mixture.
  • If you want to cut the carbs further and make this a truly keto-friendly dish, you can reduce the tomato paste to 1/4 cup. You’ll have to simmer a little longer to thicken the mixture, but it is still delicious.
  • You can also swap the Worcestershire sauce for Coconut Aminos. This affects the taste slightly, so you might need to adjust the salt and pepper a bit.
  • Place the casserole dish on a baking sheet to catch anything that may bubble over and avoid a mess in your oven.
  • And if you are looking for other ways to eat healthy shepherd’s pie, you could spoon the mixture into individual ramekins like these mini shepherd’s pies. Or use this low carb recipe in Shepherd’s Pie Stuffed Peppers

Does Shepherd’s Pie have cheese on top?

Some people put cheese on top of Shepherd’s Pie, while others don’t It is truly a personal preference, and neither right nor wrong either way.

Personally, I’ll take any opportunity to enjoy more of my favorite Sharp Cheddar Cheese from Cabot Creamery Co-operative. I love that sharp bite against the smooth and creamy cauliflower and the savory beef mixture in this Low Carb Shepherd’s Pie Recipe.

    Nice recipe but it ain’t shepherds pie, as it should use minced lamb (the clue is in the name)! =) Shepherds Pie is a British recipe, and if it is cooked with beef, it is called Cottage Pie. Sorry to be a bit pedantic, but both are delicious and it’s worth trying the lamb version and posting it!
