It’s spaghetti squash time! While you can usually get it year round, spaghetti squash is usually harvested in the early fall, which means fall and winter are when you’ll get the best price at the grocery store. We love spaghetti squash in our house, so we’re buying it often, but especially in the cooler months. We enjoy it as a side dish, such as in our favorite Bacon-Parmesan Spaghetti Squash Recipe and we love it as a main dish such our Baked Pesto Spaghetti Squash Recipe — which is great with chicken added to it.
The recipe we’re sharing today is another great version. This Easy Baked Spaghetti Squash with Meat Sauce Recipe is very similar to our popular 3-Ingredient Twice-Baked Spaghetti Squash Recipe, however, this one adds ground beef for our meat lovers. There is also some onion and garlic added for even more flavor. It’s an easy dinner idea with only 7 ingredients and by using spaghetti squash instead of pasta, this is a low carb dinner too (as long as you use a low carb spaghetti sauce).
How to Cut Spaghetti Squash
The hard exterior of spaghetti squash can be intimidating and even if you have great knives, you might find it to be a challenge to cut it.
For this recipe, you’ll need to cut each spaghetti squash in half lengthwise. To make it easier to cut your spaghetti squash, we recommend using the tip of a sharp knife and carefully poking in a dotted line around the entire spaghetti squash from the stem down to the bottom and up again to the stem. Then, place the spaghetti squash in the microwave for 5 minutes. This will soften the hard shell of the spaghetti squash just enough to make it a bit easier to cut. Cut your squash fully into two halves, along the dotted line that you created previously. Scoop out all of the seeds and discard them.
How to Roast Spaghetti Squash
There are many ways to cook it spaghetti squash, but my favorite method is to roast spaghetti squash in the oven. To do this, place each half, cut side down, on a baking sheet and bake at 375 degrees F until the spaghetti squash is tender, about 45 minutes.
How to Cook Spaghetti Squash in the Microwave
If you are short on time, you can cook spaghetti squash in the microwave. To do this, place your cut spaghetti squash on a microwave-safe baking dish (a size that will fit in your microwave), cut side up. If your spaghetti squash is small-medium sized, you can probably cook two halves at the same time for about 18-20 minutes. But your spaghetti squash is larger, you may need to cook each spaghetti squash half separately for about 10 minutes each.
After you have cooked two spaghetti squashes, take a fork and loosen and separate the spaghetti squash strands from all four shells. Place them in a mixing bowl. Set the empty spaghetti squash shells in a baking dish or on a baking sheet.
Add 1 cup of shredded mozzarella cheese and 1/2 cup of shredded parmesan cheese to the bowl with the cooked spaghetti squash.
In a large skillet, cook together the ground beef, diced onion, and minced garlic. Combine the cooked ground beef mixture with your spaghetti sauce and set aside.
Divide the spaghetti squash and cheese mixture between the four empty squash shells.
Do the same with the meat mixture — divide the meat between to the four spaghetti squash shells, placing it right on top of the spaghetti squash/cheese mixture.
Top the meat mixture with extra shredded cheese. Bake for 20-25 minutes, until the cheese is melted and begins to brown.
Remove from the oven and your Easy Baked Spaghetti Squash with Meat Sauce is ready to serve, right from the shells.
In general, each spaghetti squash boat will serve 1 person, but this may depend on the size of your spaghetti squash and appetites.
