📝 Instructions

11 steps
1

Preheat your oven to 400°F (200°C).

2

Slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle each half with 1 tablespoon of olive oil and a pinch of salt and pepper.

3

Place the squash halves cut-side down on a baking sheet lined with parchment paper. Roast in the oven for 35-40 minutes, or until the squash is tender and easily shredded with a fork. Remove from the oven and let it cool slightly.

4

While the squash is roasting, prepare the marinara sauce. Heat 1 tablespoon of olive oil in a large skillet or saucepan over medium heat.

5

Add the diced onion to the pan and sauté for 3-4 minutes, or until softened.

6

Add the minced garlic and sauté for 1 additional minute, until fragrant.

7

Stir in the crushed tomatoes, tomato paste, chopped basil, dried oregano, red pepper flakes (if using), salt, and black pepper. Mix well to combine.

8

Reduce the heat to low and let the sauce simmer for 15-20 minutes, stirring occasionally, to allow the flavors to meld together.

9

Once the squash is cool enough to handle, use a fork to scrape out the strands of 'spaghetti' into a large bowl.

10

Serve the spaghetti squash topped with a generous portion of marinara sauce. Garnish with fresh parsley.

Enjoy your Whole30-compliant Spaghetti Marinara!
