How To Make the Stuffed Spaghetti Squash with Sausage and Spinach

Step 1: Roast the Spaghetti Squash

Preheat your oven to 400°F. Slice the squash in half lengthwise, scoop out the seeds, and drizzle with olive oil. Sprinkle with salt and pepper, then place cut-side down on a baking sheet. Roast for 35 to 40 minutes, until tender and easily shredded with a fork.

Step 2: Cook the Sausage and Spinach

While the squash roasts, heat olive oil in a skillet over medium heat. Add the sausage, breaking it up with a spoon, and cook until browned. Stir in minced garlic, then add spinach and sauté until wilted. Season with salt, pepper, and red pepper flakes for a little heat.

Step 3: Assemble the Filling

Add tomato sauce to the sausage-spinach mixture and let it simmer for a few minutes to meld the flavors. Taste and adjust the seasoning if needed.

Step 4: Stuff and Bake

Once the squash is roasted, use a fork to gently shred the flesh into strands while still in the shell. Spoon the sausage mixture over the squash, then top generously with shredded mozzarella and a sprinkle of parmesan. Return to the oven and bake for 10 to 15 minutes, until the cheese is melted and bubbly.

Step 5: Serve and Enjoy

Let the squash cool slightly before serving. Use a fork to twirl the squash strands and scoop up all that melty, saucy goodness in every bite.

How to Serve and Store This Stuffed Spaghetti Squash with Sausage and Spinach

This dish serves two people generously when using one large spaghetti squash split in half. If you’re cooking for more, simply double the ingredients and roast multiple squash halves at once.

Serve it straight from the shell for a fun, rustic presentation that makes cleanup a breeze. The roasted squash holds everything together, and digging in with a fork to pull up those strands with cheesy sausage sauce is half the joy.

To store leftovers, scoop the filling into an airtight container and refrigerate for up to four days. Reheat in the microwave or oven until warmed through. You can also freeze the filling separately for up to a month.
