I’ll be honest with you and say that my family and I love a good comfort food meal for dinner, especially when the fall nights are getting colder and colder. That’s why this Whole30 Low-Carb Spaghetti Squash With Meatballs recipe is total a winner here in my house.

We love this spaghetti squash with meatballs so much because it’s so flavourful, warm, hearty and rich with all the fresh homemade tomato sauce and the yummy meatballs.

Also, if you prefer to make this recipe using store-bought tomato sauce to save some time, it’s totally fine. Or you can make the tomato sauce ahead of time and freeze it as well.

So, if you prepare the meatballs and the tomato sauce over the weekend, the only thing you will need to do is to cook the spaghetti squash in the microwave (if you prefer to roast it, I teach how to do it below) and assemble it quickly midweek.

How to roast spaghetti squash:

1. Preheat oven to 375°F.
2. Lightly grease a baking sheet with cooking oil spray.
3. Then, wash the outside of the squash and using a sharp knife cut the squash in half lengthwise from stem to tail.
4. Using a spoon, scoop out and discard seeds from the middle of each half.
5. Drizzle some olive oil on top of each half of the squash and season with salt and pepper to taste.
6. Arrange squash on baking sheet, cut-side down. Roast for about 45-50 minutes, depending on the size of your squash.
7. Remove from oven and allow to cool for about 10 minutes before handling. Then, gently scrape the sides of the squash with a fork to shred the pulp into strands. Place it on a plate and enjoy!

How to cook spaghetti squash in a microwave:

I cook spaghetti squash in the microwave in two different ways. The first way I explain below and the second way I explain on the recipe card. I love both methods and it’s totally up to you, which method to choose.

2. Place the spaghetti squash on a microwave safe dish and microwave on medium-high for 5 minute.

6. Scoop the seeds with a spoon.

8. Place the flesh in a skillet with olive oil, salt and pepper. Sauté for about 5 minutes and enjoy!

2. Place the squash on the trivet and add 1 cup of water in the pot.
3. Cook on high pressure for 15 minutes for a 3-pound squash. (The time will depend on the size of your squash. If it is larger, add 3 more minutes to the cook time.)
4. Release the pressure naturally for 10 minutes.
5. Then, manually turning the pressure release valve to venting.
6. Open the Instant Pot and let the squash to cool down for 5 minutes before remove it. Then using oven mitts, remove the squash.
