What Kind of Sausage Should I Use?

Italian sausage is the go-to here, but both sweet and hot versions work beautifully depending on your spice preference. Pork is classic, but turkey sausage is a leaner option if you’re aiming for a lighter dish without sacrificing flavor.

Ingredients for the Stuffed Spaghetti Squash with Sausage and Spinach

Spaghetti Squash: This golden gourd transforms into tender, pasta-like strands that hold the stuffing like a champ.
Italian Sausage: Provides savory depth and richness, and turns this into a truly satisfying main course.
Fresh Spinach: Balances the richness of the sausage with fresh, earthy greens.
Mushrooms: Add umami and texture that perfectly complement the squash and sausage.
Cherry Tomatoes: Juicy bursts of acidity to brighten up the whole dish.
Shredded Mozzarella Cheese: Melts over the top for that irresistibly gooey, golden finish.
Olive Oil, Garlic, and Herbs: These aromatics tie everything together and elevate every bite.

How To Make the Stuffed Spaghetti Squash with Sausage and Spinach

Step 1: Roast the Squash

Cut the spaghetti squash in half lengthwise and scoop out the seeds. Brush with olive oil and season with salt and pepper. Roast cut-side down at 400°F for about 35-40 minutes, or until fork-tender.

Step 2: Cook the Sausage Filling

In a large skillet, cook Italian sausage over medium heat until browned and cooked through. Drain excess fat if needed. Add chopped garlic, mushrooms, and cook until softened. Toss in fresh spinach and cook until wilted.

Step 3: Add Tomatoes and Seasoning

Stir in halved cherry tomatoes and sprinkle in your favorite Italian herbs (think thyme, oregano, basil). Let it simmer for a couple of minutes so the flavors blend.

Step 4: Assemble the Boats

Use a fork to fluff the squash strands in their shells. Top with the sausage-spinach mixture, and sprinkle generously with shredded mozzarella.

Step 5: Bake and Melt

Place the stuffed squash halves back in the oven at 375°F for 10-15 minutes, or until the cheese is melted and bubbly with golden edges.

How to Serve and Store This Stuffed Squash

Serve the squash hot, straight from the oven, garnished with fresh herbs like thyme or parsley. Leftovers store well in the refrigerator for up to 4 days. To reheat, pop it in the microwave or warm in the oven at 350°F until heated through.

Freezing? You bet. Wrap tightly in foil and store in an airtight container. Reheat from frozen at 375°F for 20-25 minutes.
