Ingredients You’ll Need

Each ingredient plays a part to create a perfectly balanced Italian Sausage Spaghetti Squash Skillet Recipe. Choosing fresh sausage with bold flavor and a ripe spaghetti squash will make a noticeable difference in the final dish.

• Spaghetti squash: The star that replaces pasta with a light, naturally noodle-like texture.
• Extra virgin olive oil: Adds richness and helps roast the squash beautifully.
• Salt and pepper: Basic seasoning that brings all the flavors together.
• Sausage: I prefer Italian sausage because it delivers authentic flavor and a nice spice kick.
• Red bell peppers: Adds sweetness and a pop of color to brighten the dish.
• Onion: Provides a savory base flavor – finely diced is best.
• Garlic: Minced garlic gives that irresistible aromatic punch.
• Italian seasoning: Keeps the flavors traditional and herbaceous without extra effort.
• Tomato paste: Adds depth and subtle acidity for balanced richness.
• Heavy cream: Gives the dish a luscious, velvety sauce that coats everything perfectly.
• Parmesan cheese: Grated fresh, it melts right in to enhance creaminess and add umami.
• Fresh parsley (optional): A bright garnish that lifts the whole dish just before serving.

Variations

One of my favorite things about this Italian Sausage Spaghetti Squash Skillet Recipe is how flexible it is. You can easily make it your own by switching up a few ingredients or adding something extra to suit your taste or dietary needs.

• Spicy twist: I sometimes sprinkle in crushed red pepper flakes for a little heat, which my husband absolutely loves.
• Greens upgrade: Adding handfuls of baby spinach or chopped kale towards the end gives a fresh, healthy boost.
• Swap the sausage: For a lighter version, ground turkey Italian sausage works well without losing flavor.
• Cheese options: Try mozzarella or pecorino romano instead of Parmesan for a different cheesy note.

How to Make Italian Sausage Spaghetti Squash Skillet Recipe

Step 1: Roast the spaghetti squash to tender perfection

Start by preheating your oven to 350°F. Slice the spaghetti squash in half lengthwise — this can be a little tough, so be careful and use a sharp knife. Scoop out the seeds and drizzle the cut side with olive oil, seasoning generously with salt and pepper. Place the halves face down on a baking sheet lined with parchment for easy cleanup. Roast for 45-60 minutes until the squash is soft and you can easily scrape out strands that look like thin spaghetti — that’s the magic! I love roasting it early in the day so it’s ready when I start the sauce.

Step 2: Brown the sausage with love

While the squash is roasting, heat a large skillet over medium heat and add the sausage slices. Cook them until they’re nicely browned and cooked through, usually about 5 to 10 minutes depending on thickness. Don’t rush this step — browning builds flavor and texture. Once done, transfer the sausage to a plate and tent loosely with foil to keep warm. You’ll come back to the skillet shortly!

Step 3: Sauté the peppers, onions, and garlic

There should be some flavorful fat left in the pan from the sausage; if not, add a splash of olive oil. Toss in your diced red bell peppers and onions, seasoning lightly with salt and pepper. Cook for about 3 to 5 minutes until everything softens and gets just a bit of caramelization. Stir in the minced garlic and cook for an additional 30 seconds, just until fragrant — this quick burst of garlic flavor is essential!

Step 4: Build the creamy, savory sausage sauce

Add the Italian seasoning, tomato paste, and heavy cream to the skillet, stirring everything together until well combined. Turn up the heat slightly and let the sauce cook for 1 to 2 minutes — you want it hot and gently bubbling so flavors meld and the cream thickens just a bit. This sauce is what really sets this Italian Sausage Spaghetti Squash Skillet Recipe apart, bringing a rich, luscious finish without feeling heavy.

Step 5: Finish with cheese and toss it all together

Turn off the heat and stir in the Parmesan cheese until it melts into a silky, cheesy sauce. Add the browned sausage back into the pan along with your roasted spaghetti squash strands. Gently toss everything to coat the squash evenly with the creamy, cheesy sauce. Give it a quick taste and adjust salt and pepper if needed. If you’re feeling fancy, sprinkle some chopped fresh parsley on top for that bright, fresh note that makes a difference.

How to Serve Italian Sausage Spaghetti Squash Skillet Recipe

Garnishes

I almost always top this skillet with a sprinkle of fresh parsley for color and brightness. Sometimes I add a little extra grated Parmesan too — it just takes the dish to the next level. If you like a touch of heat, a pinch of crushed red pepper flakes on top does wonders.

Side Dishes

My go-to side for this recipe is a simple green salad with a tangy vinaigrette to cut through the richness. Crusty garlic bread also pairs beautifully if you’re not strictly avoiding carbs. For a low-carb option, roasted or steamed green beans or a Caesar salad work perfectly to round out the meal.

Creative Ways to Present

For dinner parties, I like to serve this Italian Sausage Spaghetti Squash Skillet Recipe straight in elegant cast-iron skillets, right at the table — it’s cozy and inviting. Another fun idea is to roast the squash halves and serve the finished mix inside them for an eye-catching presentation that’s also practical.

Make Ahead and Storage

Storing Leftovers

I store any leftovers in an airtight container in the fridge where they keep well for up to 3-5 days. The spaghetti squash holds up nicely, and the flavors even deepen after a day. Just make sure to cool the dish completely before refrigerating to keep things fresh.

Freezing

I’ve frozen this dish on occasion with good results—simply portion into freezer-safe containers and freeze for up to 2 months. Note that the texture of the spaghetti squash can become a bit softer after freezing, so I recommend thawing overnight in the fridge for best reheating results.

Reheating

To reheat, I gently warm leftovers on the stovetop over low heat, stirring occasionally and adding a splash of cream or broth if it feels too thick. Alternatively, the microwave works in a pinch, but watch closely to avoid drying out the creamy sauce.
