Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• Spaghetti squash
• Olive oil
• Italian sausage (mild or spicy, based on preference)
• Onion
• Garlic
• Crushed tomatoes or marinara sauce
• Italian seasoning
• Salt and pepper
• Mozzarella cheese
• Parmesan cheese
• Fresh parsley (optional for garnish)

Directions

1. Preheat your oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds.
2. Drizzle the inside of the squash with olive oil, season with salt and pepper, and place cut-side down on a baking sheet. Roast for about 35–40 minutes, or until the flesh is tender.
3. While the squash is roasting, heat a skillet over medium heat. Add the sausage and cook until browned, breaking it up with a spoon.
4. Add diced onions and cook until translucent. Stir in minced garlic and cook for another 30 seconds.
5. Pour in crushed tomatoes or marinara sauce, and season with Italian seasoning, salt, and pepper. Let it simmer for 5–7 minutes.
6. When the squash is done, use a fork to scrape the flesh into strands, keeping them in the shell.
7. Stir some of the squash strands into the sausage mixture if desired, then spoon the sausage mixture into each squash half.
8. Top with mozzarella and Parmesan cheese, then return to the oven for 10–12 minutes, or until cheese is melted and bubbly.
9. Garnish with chopped parsley and serve warm.

FAQs

Can I make this ahead of time?

What type of sausage should I use?

Italian sausage (mild or spicy) works best, but any ground sausage of your choice will do.

Can I freeze this dish?

It’s best enjoyed fresh, but you can freeze assembled halves before the final bake. Reheat in the oven straight from frozen.

How do I choose a good spaghetti squash?

Is this recipe keto-friendly?

Use hot Italian sausage or add crushed red pepper flakes to the sauce for more heat.

How do I avoid watery squash?

Roast it cut-side down and don’t overcook. Let it rest after baking to let excess moisture evaporate.
