Spaghetti Squash Marinara Boats
Ingredients
- 2 large spaghetti squash
- 1 tbsp olive oil
- 1 tsp salt
- 1/2 tsp pepper
- 1.5 lbs ground turkey
- 1, 16 oz jar of marinara
- 1 yellow onion, finely diced
- 1 tbsp Italian seasoning
- 1 tbsp minced garlic
- 1 cup mozzarella cheese shredded
For the breadcrumb mixture
- 1 cup breadcrumbs
- 2 tbsp butter
- 1/2 tbsp Italian seasoning
Instructions
- Preheat your oven to 400°F. Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil and season with salt and pepper. Place the squash cut-side down on a baking sheet and roast for 40-45 minutes, or until tender and easy to shred with a fork.
- While the squash is baking, heat a drizzle of oil in a large skillet over medium-high heat. Add the ground turkey and cook for 5-7 minutes, breaking it apart as it browns.
- Add the diced onion, Italian seasoning, and garlic. Sauté for a few minutes, or until the onion begins to soften.
- Pour in the marinara sauce and stir well. Reduce the heat to low and let the mixture simmer for 5-10 minutes so the flavors can come together. Taste and season with salt and pepper as needed.
- To make the breadcrumb topping, mix the breadcrumbs, melted butter, and Italian seasoning in a small bowl until evenly combined.
- Once the spaghetti squash is tender, use a fork to gently fluff the strands while keeping them inside the shells. Spoon the turkey marinara mixture into each half, then top with shredded cheese and the seasoned breadcrumbs.
- Return the stuffed squash to the oven for about 5 minutes, or until the cheese has melted and the breadcrumbs are lightly golden. Serve warm and enjoy!
