If you’ve been reading this blog for a while, you know that I NEVER shy away from pasta (as evidenced with all the pasta recipes I share here).
That said, these cozy baked spaghetti squash boats are such a delicious, comforting option when you’re looking for something a bit lighter, or when you simply want to change things up!

About the ingredients
All you need to make this baked spaghetti squash recipe are 7 simple ingredients:
- Spaghetti squash: This type of squash is usually a yellow colour and a rounded-cylindrical shape. When cooked, its flesh can be scraped into strands that resemble spaghetti. If you can find one, I recommend purchasing a smaller spaghetti squash for this recipe (one that’s around the same length as your hand, or a tiny bit longer). They’re a little easier to work with and are a good portion size. The super big squash are a little more difficult to cut and take longer to cook!
- Olive oil: Olive oil is used to brush the spaghetti squash before placing it in the oven, and also to wilt the spinach in. That said, you may use another type of neutral-flavoured oil instead – my preference would be avocado oil.
- Spinach: Spinach is used to sneak some extra greens in the tomato sauce! If preferred, you can swap it for another leafy green, like kale or swiss chard.
- Tomato sauce: You can use any type of tomato sauce you like – store-bought marinara, tomato basil sauce, something spicier (like arrabiatta), or a homemade version as desired!
- Oregano: Dried oregano is used to add some additional Italian-inspired flavours to the tomato sauce.
- Thyme: Like oregano, dried thyme is added to the tomato sauce as well. You’re always welcome to play around with the seasonings and use something like an Italian blend or dried basil as well. If you’d like, you can garnish the finished spaghetti squash with some freshly-chopped basil, parsley, or thyme.
- Goat cheese: Goat cheese is added to the top of the squash, gets nice and melted in the oven, then stirred together with the spaghetti squash strands. It can be swapped for another type of cheese, like feta or some shredded mozzarella – or a vegan/dairy-free alternative if needed.
Please note that spaghetti squash is unique to other varieties of squash. There is no good substitute for another type of squash that will make these “spaghetti-like” strands!

Tips for cutting spaghetti squash
- Be sure to use a large, sharp chef’s knife for cutting the squash.
- I like to cut the hard ends off first, so that you can stand the squash upright and cut it in half (lengthwise).
- I find it helpful to use a dish towel to help push and wiggle the sharp end of the knife down.
- Using a smaller squash (as mentioned above) will make this whole process a lot easier!
Step-by-step: how to bake spaghetti squash
Cut spaghetti squash in half lengthwise and remove seeds and stringy-flesh.
Brush the insides of the squash with olive oil. Sprinkle salt + pepper overtop.
Flip squash face-side down onto a parchment-lined baking sheet. Bake in the oven for 30 minutes.
Meanwhile, cook spinach (or other greens) on a pan until it wilts.
Add tomato sauce and dried spices to the spinach. Stir together and cook for a few minutes.
Remove the squash from the oven and fill the insides with the tomato sauce mixture.
Crumble goat cheese on top of the tomato sauce. Return to the oven for another 15 minutes to continue cooking the squash + to melt the cheese.
Remove squash from oven. Use a fork to scrape squash strands into “spaghetti.” Stir everything together and enjoy hot!
Spaghetti squash nutrition benefits
Spaghetti squash is a delicious winter squash that comes out in spaghetti-like strands. While it doesn’t exactly compare to pasta, I still love it for its taste and impressive nutrition profile!
To start, spaghetti squash is a GREAT source of dietary fibre, with a one-cup serving providing 9% of your daily needs (2.2 grams). Fibre plays an important role in promoting digestive health, lowering cholesterol, balancing blood sugar, and helping us feel satiated!
Spaghetti squash is also high in certain micronutrients like:
- vitamin C
- vitamin B6
With its vibrant yellow colour, spaghetti squash is also rich in antioxidants (like beta-carotene and vitamin C), which helps to fight free radical damage to your body’s cells.
