Why You’ll Love This Roasted Spaghetti Squash With Alfredo Sauce and Cheese

This dish is perfect for busy nights when you want something warm and creamy without the heavy carbs of traditional pasta. It comes together with just a handful of ingredients but feels gourmet thanks to the depth of flavor in the sauce and the toasty finish of cheese on top. Plus, it’s flexible: you can customize it with your favorite cheeses, add cooked chicken or shrimp, or make it fully plant-based with dairy-free substitutes.

What Kind of Alfredo Sauce Should I Use?

You can absolutely make your own Alfredo sauce from scratch with butter, cream, and parmesan if you’re in the mood for something homemade. But for weeknights, a high-quality jarred Alfredo sauce works wonders and saves time. Look for one that uses real cream and cheese for the most authentic flavor. If you’re dairy-sensitive, there are excellent plant-based Alfredo options made with cashews or cauliflower that still offer a creamy consistency.

Ingredients for the Roasted Spaghetti Squash With Alfredo Sauce and Cheese

Spaghetti squash is the star of this dish, and everything else just enhances its delicate texture and flavor. Here’s what you’ll need:

Spaghetti Squash
Roasted until tender, it transforms into noodle-like strands that serve as the base.

Olive Oil
Used for roasting the squash, adding flavor and helping achieve that golden finish.

Salt & Black Pepper
Essential for seasoning the squash and elevating every bite.

Alfredo Sauce
Creamy and garlicky, this coats the squash beautifully and brings richness.

Mozzarella Cheese
Melts over the top for that irresistible cheesy pull.

Parmesan Cheese
Adds a nutty, salty kick that balances the creamy Alfredo.

Fresh Parsley
Optional but adds a bright, herby finish that lightens up the dish.

How To Make the Roasted Spaghetti Squash With Alfredo Sauce and Cheese

Step 1: Roast the Squash

Preheat your oven to 400°F. Slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle each half with olive oil and season with salt and pepper. Place them cut-side down on a baking sheet lined with parchment paper and roast for about 40 minutes until tender.

Step 2: Scrape and Prepare

Once the squash is cool enough to handle, use a fork to scrape out the flesh into long strands. Transfer the strands to a bowl or return them to the squash shells for serving.

Step 3: Add Alfredo Sauce

Warm your Alfredo sauce in a saucepan or microwave and pour it over the squash. Toss everything gently so the sauce coats all the strands evenly.

Step 4: Top with Cheese

Sprinkle the mozzarella and parmesan cheese generously over the squash. If using the shells as bowls, top them right inside the halves for a rustic look.

Step 5: Broil to Finish

Place the squash under the broiler for 2 to 3 minutes until the cheese is melted and golden. Keep a close eye to avoid burning.

Step 6: Garnish and Serve

Finish with a sprinkle of fresh parsley and serve warm. It’s cheesy, creamy, and packed with comfort.

Serving and Storing Your Spaghetti Squash Alfredo

This recipe yields about 4 servings as a main dish or 6 to 8 if you’re serving it as a side. It’s a hit on cozy weeknights but also elegant enough for dinner parties when you want to offer a veggie-forward option.

If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through. The squash may release a little moisture after storing, but it will still be delicious.
