Ingredients

• 1 medium-sized Spaghetti squash
• 2 tablespoons Olive oil
• 1 medium Yellow onion, finely diced
• 3 cloves Garlic, minced
• 28 ounces Crushed tomatoes (no sugar added)
• 2 tablespoons Tomato paste (no sugar added)
• 2 tablespoons Basil, chopped
• 1 teaspoon Oregano, dried
• 0.5 teaspoons Red pepper flakes (optional)
• 1 teaspoon Salt
• 0.5 teaspoons Ground black pepper
• 2 tablespoons Fresh parsley, chopped (for garnish)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 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.

Step 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.

Step 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.

Step 5

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

Step 6

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

Step 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.

Step 8

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

Step 9

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

Step 10

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

Step 11

Enjoy your Whole30-compliant Spaghetti Marinara!
