Cheesy Stuffed Acorn Squash Recipe

For many people, the pasta is the comfort food element they love most about classic homemade lasagna. But if you are all about the sauce, meat, and cheese, this is the meal for you. And when you are craving that cheesy goodness but don’t have time to make all those layers, this is the perfect easy dinner for budy nights.

As a bonus, it’s budget-friendly, too. Acorn squash recipes can be a very frugal choice, especially in the fall and winter when it is in season. Ground beef recipes are also economical options, and the only other things you need are tomato sauce and cheese. 

This Italian-inspired recipe has all that ground beef and ricotta and mozzarella cheese. But it is stuffed into roasted acorn squash for a bowl you can eat. So you get your protein and your veggies all in one simple dish. Plus, it’s absolutely delicious.

My family loves digging into is as one of our favorite cold weather meals! The kids think it’s fun to be able to eat their bowl, like this Turkey Chili in an Acorn Squash Bowl.

Ingredients

Here’s a quick list of what you’ll need to you can make your grocery shopping list. The full amounts are listed in the recipe card at the bottom of the post. But keep reading for more helpful tips!

  • Acorn squash: You will need two that you cut in half lengthwise and scoop out the seeds.
  • Olive oil
  • Salt and pepper
  • Ground beef: I usually use 93% lean, but go with what you like best.
  • Onion: You’ll need half of a medium one, diced.
  • Tomato sauce: Use your favorite store bought or homemade marinara sauce, or simply a small 8 oz. can of sauce.
  • Ricotta cheese: Whole milk or part skim are both fine.
  • Mozzarella cheese: You’ll want it shredded, but for the best melting, I always recommend buying a block and shredding it yourself instead of buying pre-shredded cheese in a bag.
  • Parmesan cheese: Buy it grated or freshly grate it yourself. For the best flavor, try to get fresh parmesan and not the stuff in the green canister.

About Acorn Squash

Before you make this stuffed squash recipe you have to start with roasting your acorn squash. But first, let’s talk about this delicous winter squash.

What does acorn squash taste like? 

Acorn squash has a slightly sweet and mild flavor and an almost buttery texture. It is not as strong of a flavor as butternut squash or pumpkin, which means it pairs well with a wide variety of foods.

It is often roasted with warm spices and flavors like maple syrup and cinnamon or ginger. But it also contrasts nicely with the kick of chili or cayenne pepper. You’ll often see squash recipes with meats like chicken and pork. Sometimes it is even stuffed with Italian sausage.

And it can be served or stuffed with grains like wild rice or quinoa, sweet flavors like apples or dried cranberries, and earthy herbs such as sage and thyme. These options are perfect to serve alongside a Thanksgiving turkey.

However, in this recipe, that mild sweetness and creamy texture also pair well with the creaminess of the ricotta cheese, the rich flavors of tomato, oregano, garlic, and onion in the sauce, and the toasty flavors of the melted mozzarella and parmesan cheese.

Is acorn squash gluten free?

Yes, acorn squash is gluten free, making this a great alternative with all the same flavors as a traditional gluten free lasagna

Is acorn squash a carb?

Acorn squash is definitely a higher carb veggie, so it may not fit into a keto or very low carb diet. However, compared to pasta, this is a lower-carb alternative to lasagna. In addition, these are natural carbs and sugars from the vegetable. This is definitely a better option for a good source of carbohydrates compared to processed foods and refined sugars.

How to Roast Acorn Squash

How to cut acorn squash

Cut your squash. Be very careful when cutting acorn squash. Make sure to cut it on a stable surface, such as a large wooden cutting board with a damp kitchen towel underneath. This helps to prevent the cutting board from moving around. Using a very sharp knife, cut the squash in half from top to bottom and scoop out the seeds.

Roast the squash. After cutting your acorn squash, place the halves on a baking sheet and brush the insides with olive oil. Sprinkle with salt and pepper, flip them over, and bake cut side down at 400°F for about 20 minutes.

You can then proceed with the rest of this recipe. If you are not filling your squash and just eating it roasted, you may want to give it another 5 to 10 minutes in the oven with the cut side up. Trying giving it a sprinkle of your favorite dried herbs or spices, or a drizzle of maple syrup.

Can you eat the skin of acorn squash?

After roasting, the skin of acorn squash typically becomes quite tender, so yes, you can eat it if you like. However, if you prefer not to eat the skin, the flesh does separate from the skin quite easily. That is why it is recommended to roast acorn squash with the skin on. Due to the thickness of the skin and the grooves, it is very difficult to peel before baking.

How to Make Stuffed Acorn Squash

Make the meat sauce. While the acorn squash roasts, heat a bit of olive oil in a skillet over medium heat. Add the ground beef and onions, plus a pinch of salt and pepper. Then saute, breaking up the ground beef while it is cooking until it is no longer pink. Stir in the tomato sauce, and adjust seasonings to taste.

Stuff the squash. Remove the squash from the oven, flip each side over, and fill the squash halves with ricotta cheese and the meat sauce mixture. Top with mozzarella and parmesan cheese and pop the stuffed squash abck in the oven just until the cheese melts and browns slightly.

Tips for Success

  • Be budget-friendly. While you can use a jar of marinara or make your own, a simple, inexpensive 8 oz. can of tomato sauce is all you need. There is just enough in the can and you won’t have leftovers from a jar to go to waste.
  • Save time. Take a few minutes to prep your squash, and while it is roasting, prepare the fillings.
  • Change the meat. Feel free to substitute the ground beef with ground chicken or turkey for a leaner option. You can also use ground pork or Italian sausage removed from its casings to add additional flavor.
  • Make it vegetarian. Alternatively, skip the meat altogether or add some chopped mushrooms or chickpeas for a vegetarian option.

Storing Leftovers

If wrapped or sealed well, your stuffed acorn squash can be refrigerated for 2 or 3 days. You can reheat it in the microwave for 2-4 minutes until heated through. Or pop it back in a 400°F oven for 5-10 minutes, until hot.

You can also freeze it for up to two months. Just be sure to thaw overnight in the refrigerator before reheating.
