Preparation Phase & Tools to Use
Before diving into the cooking process, it’s essential to prepare your kitchen and gather the necessary tools to make Roasted Spaghetti Squash With Alfredo Sauce and Cheese a breeze. Start by preheating your oven to 400°F (200°C). Grab a sturdy cutting board and a sharp knife to safely slice the spaghetti squash in half; if you find it difficult to cut, microwaving the squash for 2-3 minutes will soften it enough for easy slicing. A baking sheet lined with parchment paper will ensure your squash roasts evenly without sticking.
Additionally, you will need a saucepan to sauté your garlic and prepare the Alfredo sauce. A whisk will come in handy for mixing your cream and cheese to attain the velvety texture we all love in an Alfredo sauce. Finally, a fork is essential for shredding the roasted squash into those desirable spaghetti-like strands. With these tools in hand, you’ll be all set to create this irresistible dish!

Ingredients
- 1 large spaghetti squash (about 2.5 to 3 lbs)
- 2 tablespoons olive oil
- Salt and freshly ground black pepper (to taste)
- 2 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 1/4 cups heavy cream
- 1/2 cup whole milk (optional)
- 1 cup freshly grated Parmesan cheese
- 1/2 cup shredded mozzarella cheese (for sauce)
- 1/2 cup shredded mozzarella cheese (for topping)
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon red pepper flakes (optional)
- 2 tablespoons chopped parsley (for garnish)
- Optional: cooked chicken, sautéed mushrooms, spinach, or sun-dried tomatoes
Instructions
Step 1: Preheat and Prepare the Squash
Begin by preheating your oven to a cozy 400°F (200°C). Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds. This process will allow the squash to roast perfectly, yielding tender strands after baking. Next, drizzle a small amount of olive oil onto the insides of each squash half, seasoning generously with salt and pepper to enhance the natural flavors.
Step 2: Roast the Squash
Once seasoned, place the squash cut-side down on a parchment-lined baking sheet. This will help caramelize the surfaces while roasting. Slide the baking sheet into your preheated oven and allow the squash to roast for approximately 35-40 minutes. The squash is done when you can easily pierce the flesh with a fork, ensuring those delightful strands are tender and ready to be transformed into your meal.
Step 3: Prepare the Alfredo Sauce
While the squash is roasting, it’s the perfect opportunity to whip up the homemade Alfredo sauce. In a medium saucepan, melt the unsalted butter over medium heat. Add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to let it brown. Slowly stir in the heavy cream and the optional milk, letting the mixture come to a gentle simmer. Allow it to simmer for about 3-4 minutes before lowering the heat.
Step 4: Add Cheese and Seasoning
Stir in the grated Parmesan cheese along with 1/2 cup of shredded mozzarella cheese, mixing until the cheese has melted and blended smoothly into the sauce. Enhance the flavor profile by adding ground nutmeg and red pepper flakes, if desired. This infusion of flavors will give your Alfredo sauce that warm, comforting essence that pairs so well with the squash.
Step 5: Combine Squash and Sauce
Once the squash is perfectly roasted, let it cool slightly before shredding the flesh with a fork to create those beautiful strands. In a mixing bowl, combine the shredded squash with the warm Alfredo sauce. If you wish to add some protein or vegetables to your dish, now is the time to fold in the cooked chicken, spinach, or sautéed mushrooms for an extra nutritious boost.
Step 6: Bake to Perfection
Spoon the spaghetti squash and Alfredo mixture back into the hollowed-out squash shells or transfer it into a greased baking dish. Sprinkle the remaining 1/2 cup of mozzarella cheese evenly over the top. Place your dish back into the oven and bake for an additional 10-15 minutes, or until bubbly and golden brown on top. This finishing touch ensures a delightful cheesy crust that adds another layer of flavor and texture to your meal.
Step 7: Serve and Enjoy
Once baked, allow your Roasted Spaghetti Squash With Alfredo Sauce and Cheese to cool for about 5 minutes before serving. Garnish with fresh parsley for a pop of color and freshness. This dish is best enjoyed warm, showcasing the beautiful interplay of flavors and textures. Your family will love this comforting, creamy alternative to traditional pasta!
