Stuffed Spaghetti Squash Boats

My absolute favorite spaghetti substitute is spaghetti squash. It has a sweet flavor that compliments heavy sauces such as the sauce in my Spaghetti Squash Alfredo Recipe and it helps cut through the richness of my Meat Lovers Spaghetti Squash Casserole.

Roasting spaghetti squash, as opposed to steaming, brings it to another level. It is nowhere near mushy and yields al dente, pasta-like strands in a shorter amount of time. It's truly the only way to cook spaghetti squash! This is the exact method I use to make my Baked Feta Pasta with cherry tomatoes.

When my kids were little I could feed them spaghetti squash and they would be none the wiser! Those days are gone, unfortunately. That's okay, though, that means more for my meal prep!

What you need

Here's what you need for this low-carb spaghetti squash recipe (the printable recipe card is toward the bottom of this page):

2 spaghetti squash: Spaghetti squash range from 2-4 pounds. Smaller ones will feed 2 people and larger ones could feed 4 depending on someone's appetite. So each person gets their own half, I recommend a small to medium squash.

Seasonings for the squash: Salt and black pepper are a must. Other flavor additions would be red pepper flakes and/or Italian seasoning.

2-4 tablespoons avocado oil: or any oil such as olive oil or canola.

24-36 ounces marinara sauce: I recommend making my Keto Spaghetti sauce for this recipe, but you can also use your favorite store-bought marinara sauce and mix it with cooked ground meat.

1 pound lean ground beef or sweet Italian sausage: Italian sausage in spaghetti sauce is a great way to inject even more flavor into this dish. Other options are ground turkey, spicy Italian sausage, or chicken sausage.

Shredded mozzarella cheese and parmesan cheese: The amounts depend on how many people you serve. Each person would require at most ½ cup of cheese (unless you want your spaghetti squash boats extremely cheesy).

Additions to consider: You really can make this stuffed spaghetti squash recipe your own. For added greens, you can wilt fresh spinach into the ground meat. That would be a recipe with lots of veggies! Use cooked chicken breast instead of ground meat for a cheesy chicken spaghetti bake.

How to make stuffed spaghetti squash boats

Let me show you how to make this keto-friendly spaghetti squash recipe step-by-step.

Roast the spaghetti squash:

  1. Microwave: My trick to make sure spaghetti squash isn't mushy is to microwave it for 5 minutes (make sure to use a sharp paring knife to stab a large gash in it so it can release steam) so it is easier to cut.
  2. Get ready for roasting: Let the squash cool so you can handle it, then use a sharp knife to cut the squash in half lengthwise.
  3. Scrape out the seeds: Use a spoon to scrape out the center of each squash half, which contains the seeds.
  4. Season and roast: Coat each half with oil using a brush, season with salt, pepper, and other seasonings of choice, and place flesh side down on a baking sheet. Roast the spaghetti squash at 425F for 25-30 minutes or until the squash can easily be pierced with a fork. The cooking time will vary based on the size of the squash.

Make the sauce:

I highly suggest my keto spaghetti sauce recipe or use 24-36 ounces of your favorite jarred sauce for your spaghetti squash bowls. My sauce recipe uses fresh herbs and whole canned tomatoes that are pureed into a tomato sauce for the least amount of carbs (perfect for the keto diet). In place of the ground beef in that recipe, use ground turkey or ground Italian sausage if you prefer.

Stuff the spaghetti squash boats:

  1. Make the strands of spaghetti squash: Use a fork to scrape the flesh away from the spaghetti squash shells to make spaghetti squash noodles. Taste the noodles for seasoning. It will most likely need more salt.
  2. Pour the sauce: Ladle a couple of spoonfuls of sauce into each spaghetti squash half, and mix the sauce into the noodles with a fork.
  3. Top with cheese: Sprinkle mozzarella and parmesan cheeses over the spaghetti squash mixture.
  4. Broil: Place the squash back on the baking sheet and put under the broiler to melt the cheese. Alternatively, you can put them in a large baking dish. Watch carefully so they don't burn!

    When I remove the squash from the oven, while it is still very warm, I mix 1/2 cup of Parmesan cheese and mix in while shredding. No more watery spaghetti squash. No need to add more before browning, the Mozzarella will be enough. Love this recipe!
