Ingredients You’ll Need
· 1 lb rotini pasta (or any short pasta shape)
· 4 tablespoons unsalted butter
· 4 cloves garlic, minced
· ¼ cup all-purpose flour
· 2 cups whole milk (or half-and-half)
· 1 cup heavy cream
· 1 ½ cups shredded mozzarella cheese, divided
· 1 cup grated Parmesan cheese, divided
· 1 teaspoon Italian seasoning
· ½ teaspoon salt
· ½ teaspoon black pepper
· ¼ teaspoon red pepper flakes (optional)
· ½ cup diced tomatoes or red bell peppers (optional, for color)
· Fresh parsley, chopped (for garnish)
Optional add-ins: 2 cups cooked diced chicken, 2 cups steamed broccoli florets, 1 cup sautéed mushrooms, ½ cup crumbled bacon.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Cook the Pasta: Cook the rotini in a large pot of salted boiling water according to package directions, but reduce the cooking time by 1–2 minutes so it’s slightly underdone (al dente). Drain and set aside.
- Make the Garlic Cream Sauce: In a large saucepan over medium heat, melt the butter. Add the minced garlic and sauté for 1 minute until fragrant. Whisk in the flour and cook for 1 minute to create a roux.
- Add the Liquids: Gradually whisk in the milk and heavy cream. Continue whisking until the sauce is smooth and slightly thickened, about 3–5 minutes.
- Add the Cheese and Seasonings: Reduce the heat to low. Stir in 1 cup of mozzarella, ½ cup of Parmesan, Italian seasoning, salt, pepper, and red pepper flakes (if using). Stir until the cheese is melted and the sauce is smooth.
- Combine Pasta and Sauce: Add the cooked pasta to the sauce and toss to coat evenly. If using diced tomatoes or bell peppers, fold them in now.
- Assemble the Bake: Pour the pasta mixture into the prepared baking dish. Sprinkle the remaining ½ cup mozzarella and ½ cup Parmesan evenly over the top.
- Bake: Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and golden brown. For an extra crispy top, broil for 2–3 minutes at the end, watching closely.
- Garnish and Serve: Garnish with fresh chopped parsley and serve hot.
Tips for the Best Creamy Garlic Parmesan Baked Rotini
· Don’t Overcook the Pasta: Cook it al dente so it doesn’t become mushy when baked.
· Use Freshly Shredded Cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Freshly shredded mozzarella and Parmesan melt beautifully.
· Make the Sauce Smooth: Whisk constantly when adding the milk and cream to avoid lumps.
· Add Protein: Cooked chicken, bacon, or sausage turn this side dish into a hearty main course.
· Watch the Broiler: If broiling, stay by the oven. Cheese can go from golden to burnt in seconds.
Variations & Substitutions
· Chicken Parmesan Pasta Bake: Add 2 cups cooked diced chicken and top with extra Parmesan.
· Broccoli Cheddar Rotini: Substitute cheddar for mozzarella and add 2 cups steamed broccoli.
· Spicy Arrabbiata Bake: Add ½ teaspoon red pepper flakes and 1 cup marinara sauce.
· Gluten-Free: Use gluten-free pasta and gluten-free flour for the roux.
· Vegan: Use plant-based butter, milk, and dairy-free cheese.
