How to Make Cheesy Sausage-Stuffed Spaghetti Squash

Step 1: Roast the Spaghetti Squash

Start by preheating your oven to 400°F (200°C). Cut your spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil, sprinkle generously with salt and pepper, and place them cut side down on a baking sheet. Roast for 35 to 40 minutes until the flesh becomes soft and easily shredded with a fork. This roasting step brings out the natural sweetness and helps the strands separate beautifully.

Step 2: Brown the Sausage

While the squash bakes, set a skillet over medium heat and add the Italian sausage. Break it up as it cooks so every bit browns evenly and develops a rich, savory flavor foundation. The sausage is the heart of Cheesy Sausage-Stuffed Spaghetti Squash, so take your time to let it get golden and crumbly!

Step 3: Sauté Onion and Garlic

Once the sausage is browned, toss in the diced yellow onion and minced garlic. Keep stirring until the onions soften and the garlic turns fragrant, about 3 to 4 minutes. These aromatics infuse your filling with even more Italian flair.

Step 4: Season and Simmer

Sprinkle in the Italian seasoning and, if you love some heat, red pepper flakes. Stir in the marinara sauce, then let everything simmer for a couple of minutes to meld. You’re building that crave-able, saucy filling that sets Cheesy Sausage-Stuffed Spaghetti Squash apart from the rest!

Step 5: Shred the Squash & Combine

When the squash is cool enough to handle, use a fork to gently loosen and fluff the strands, keeping them inside the shell—no extra bowls required! Stir ricotta cheese into your sausage mixture; this will make every bite luscious and creamy. Spoon the sausage-ricotta filling evenly into each squash half, tucking it right into those golden squash “boats.”

Step 6: Top and Bake

Scatter mozzarella and Parmesan cheese generously over each stuffed squash half. Slide them back into the oven for another 10 to 12 minutes, until the cheese is melted, bubbling, and golden at the edges. The kitchen will start to smell absolutely irresistible!

Step 7: Garnish and Serve

Dust with a fresh shower of chopped parsley and serve Cheesy Sausage-Stuffed Spaghetti Squash while it’s piping hot and gooey. All that’s left to do is dig into the cheesy, meaty, veggie-packed goodness.

Garnishes

For that perfect finishing touch, sprinkle with a handful of freshly chopped parsley right before serving. If you want to be extra fancy, add a dusting of extra grated Parmesan or a drizzle of good olive oil. The fresh parsley adds a bright, herby pop that balances all the gooey, cheesy richness of the dish.

Side Dishes

Cheesy Sausage-Stuffed Spaghetti Squash shines as a one-dish meal, but you can round out the table with a crisp green salad, roasted broccoli, or simple garlic bread. The dish pairs especially well with a tangy vinaigrette or garlicky veggies to add contrast to the creamy, savory squash boats.

Creative Ways to Present

Serving the squash in its own shell is already stunning and makes everyone feel special. To mix things up, try slicing each stuffed half into wedges for easy sharing, or scoop the filling into ramekins for individual squash casseroles—a fun twist on the classic Cheesy Sausage-Stuffed Spaghetti Squash!

Make Ahead and Storage

Storing Leftovers

Leftover stuffed squash keeps beautifully in the fridge. Simply cover tightly or transfer to an airtight container—the flavors will keep melding and it tastes just as good the next day. Enjoy a ready-to-go, nourishing meal for lunch or a quick weeknight dinner.

Freezing

Cheesy Sausage-Stuffed Spaghetti Squash can be frozen for up to two months. Let the stuffed squash cool completely, then wrap tightly in plastic wrap and foil or place individual portions in freezer-safe containers. Thaw overnight in the fridge before reheating for the best texture.

Reheating

To reheat, place portions on a baking sheet and warm in a 350°F (175°C) oven until heated through and the cheese is melty again. Microwaving also works for smaller portions (just cover to prevent splatters). Either way, you’ll have that signature gooey-cheesy finish every time.
