Step‑by‑Step Instructions for Stuffed Spaghetti Squash with Sausage and Spinach
Step 1: Preheat and Prepare the Squash
Preheat your oven to 400°F (200°C). Carefully cut the medium spaghetti squash in half lengthwise and scoop out the seeds. Brush the insides generously with olive oil and season with salt and black pepper. Place the squash cut-side down on a baking sheet and roast for 35–40 minutes, or until the flesh is fork-tender and can be easily shredded into strands.
Step 2: Cook the Sausage
While the spaghetti squash is roasting, heat a skillet over medium heat. Add the Italian sausage and cook for about 5–7 minutes, breaking it apart with a spatula until it’s nicely browned. Make sure to stir occasionally to achieve an even color and avoid burning. This savory base will enhance the flavor of your Stuffed Spaghetti Squash.
Step 3: Sauté the Vegetables
Once the sausage is browned, add the minced garlic and sliced mushrooms to the skillet. Cook for an additional 3–4 minutes until the mushrooms have softened and released their juices. The delicious aroma will fill your kitchen, signaling that it's time to bring in the fresh ingredients for the filling.
Step 4: Add Spinach and Tomatoes
Stir in the fresh spinach, allowing it to wilt for about 2 minutes. Then, add the halved cherry tomatoes and sprinkle in Italian seasoning. Let this mixture simmer for 2–3 minutes, stirring occasionally. The juicy tomatoes and tender spinach will create a vibrant filling for your Stuffed Spaghetti Squash.
Step 5: Fluff the Squash and Assemble
Remove the roasted spaghetti squash from the oven and use a fork to gently fluff the strands. This gives the squash a nice texture to hold your delicious filling. Carefully spoon the sausage and vegetable mixture into each half, ensuring an even distribution.
Step 6: Top with Cheese and Bake Again
Sprinkle a generous amount of shredded mozzarella cheese over the stuffed squash. Return the filled halves to the oven, lowering the temperature to 375°F (190°C). Bake for an additional 10–15 minutes, or until the cheese is melted and lightly golden, creating a beautiful topping for your Stuffed Spaghetti Squash with Sausage and Spinach. Serve warm and enjoy!

Make Ahead Options
Preparing your Stuffed Spaghetti Squash with Sausage and Spinach in advance is a fantastic way to save time during busy weeknights! You can roast the spaghetti squash up to 24 hours ahead, allowing it to cool completely before storing it in the refrigerator. Additionally, you can make the sausage and vegetable filling up to 3 days in advance; just keep it refrigerated in an airtight container to maintain its delicious flavors. When you're ready to serve, simply reheat the filling until warmed through, then stuff it into the squash and top with mozzarella before baking at 375°F (190°C) for 10-15 minutes. This approach ensures you enjoy a hearty, homemade meal just as exquisite as if freshly made, providing you with a wholesome dinner option in no time!

Stuffed Spaghetti Squash with Sausage and Spinach Recipe FAQs
How do I choose the best spaghetti squash?

Why is my stuffed squash mushy, and how can I prevent that?
Very! If your stuffed squash turns out mushy, it’s usually due to overcooking either the squash or the filling. To prevent this, monitor the roasting time closely and ensure that you don’t exceed the recommended 35-40 minutes. Additionally, allow your filling to cool slightly before adding it to the roasted squash, which helps maintain texture.
Is this recipe safe for pets, and are there any common allergies to consider?
