Spaghetti squash is one of my favorite foods, and I’d eat it multiple times a week if I had it on hand that often.

Onion: When I made this marinara spaghetti squash, I added cooked onions to the dish.

Step-by-step instructions

To make this spaghetti squash with marinara, you’ll first preheat the oven to 375° Fahrenheit.

You can make the process easier by using a fork to poke holes in the squash and microwaving it for a few minutes so it softens before you slice it.

Then microwave until the squash becomes slightly tender, about 4-6 minutes. The amount of time in the microwave depends on its size.

Slice squash in half, and remove seeds and membranes.

Place halves with cut side up on a nonstick baking tray, and brush the tops with ½ teaspoon olive oil.

Place halves with cut sides up, and roast until fork tender, about 40-50 minutes.

Once squash is cooked, remove from the oven and set aside to cool.

Use a fork to shred the squash into a large bowl. Toss with marinara.

Divide onto four plates, then top with onions and cottage cheese mixture. Sprinkle with red pepper flakes and black pepper.

The prep time is really quick, under 20 minutes. You just have to be patient for your cooked spaghetti squash to bake.

I’ll admit that I ate a double portion of this baked spaghetti squash for dinner. But you can also serve with a few ounces of grilled salmon or chicken breast for a complete meal. 

I’m really craving this dish right now! I think I’ll go start roasting spaghetti squash now. The sauce is plenty cheesy, but feel free to add a sprinkling of grated Parmesan on top if you’d like.

In addition to making this marinara spaghetti squash, you can also use spaghetti squash as a base for a veggie-noodle casserole or “pasta” salad.

You should be able to store uncooked spaghetti squash in a cool, dry pantry for up to two months.

  1. Hey, Amy. I noticed you used cottage cheese in this recipe that says it’s a plant-based recipe. You would probably want to replace the cottage cheese with tofu or cashew paste. I hope you do, because I thought it was a vegan recipe till I noticed the cottage cheese.

    1. Hi Darshana, thank you for your helpful comment! The term plant-based is quite broad and I try to be inclusive to a variety of plant-based eating styles. I appreciate your note about the vegan substitutes and will add that in the notes!
