Step‑by‑Step Instructions for Roasted Spaghetti Squash With Alfredo Sauce and Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is perfect for roasting as it helps the spaghetti squash caramelize, enhancing its natural sweetness. Gather your baking sheet and line it with parchment paper for easy cleanup.
Step 2: Prepare the Spaghetti Squash
Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds with a spoon. Drizzle the cut sides with olive oil and season with salt and pepper. Place the halves cut-side down on the baking sheet and roast in the oven for 35–40 minutes. You’ll know it’s done when the skin is tender and you can easily pierce it with a fork.
Step 3: Make the Alfredo Sauce
While the spaghetti squash roasts, prepare the homemade Alfredo sauce. In a medium saucepan over medium heat, melt the butter and sauté the minced garlic for about 1 minute until fragrant. Stir in the heavy cream and allow it to simmer gently for 2-3 minutes before adding the grated Parmesan cheese. Whisk until the cheese melts completely and the sauce becomes creamy, then season with salt and pepper to taste.
Step 4: Combine Squash and Sauce
Once the roasted spaghetti squash is cool enough to handle, use a fork to shred the flesh into spaghetti-like strands. Transfer these strands into a mixing bowl and pour the creamy Alfredo sauce over them. Gently toss until all the squash is evenly coated, making sure every strand is enveloped in that lush sauce.
Step 5: Bake with Cheese Topping
Preheat your oven broiler while you transfer the coated squash into a baking dish. Sprinkle the shredded mozzarella cheese generously over the top, ensuring an even layer. Bake in the oven at 400°F (200°C) for 10–15 minutes or until the cheese is melted and bubbly. If you prefer a golden-brown topping, broil for an additional 2–3 minutes, watching closely to avoid burning.
Step 6: Serve and Enjoy
Once your Roasted Spaghetti Squash With Alfredo Sauce and Cheese is beautifully bubbly and golden, remove it from the oven. Let it cool slightly before serving to help reach the perfect temperature. This dish is not only comforting but also a healthier alternative to traditional pasta; it’s sure to impress at your dinner table!
