Ingredients and Their Roles

Here’s everything you need for this soul-warming cheesy casserole, along with why each component matters:

• 2 cups cooked pasta (elbow macaroni or rotini)
  The hearty base of the casserole; its nooks and curves hold onto the creamy sauce beautifully.
• 2 tablespoons butter
  Adds richness and helps sauté the aromatics, forming the base of the flavor.
• 1 small onion, finely chopped
  Introduces a subtle sweetness and aromatic depth that balances the cheese.
• 2 garlic cloves, minced
  Brings sharp, savory complexity to the dish.
• 2 tablespoons all-purpose flour
  Used to make a roux, this thickens the cheese sauce to that perfect, clingy consistency.
• 1 ½ cups milk (whole milk recommended)
  The creamy base that transforms the roux into a luscious sauce.
• 1 cup shredded sharp cheddar cheese
  Delivers bold flavor and that essential cheesy pull.
• ½ cup shredded mozzarella cheese
  Offers stretchy, gooey texture and a mild creaminess.
• ½ cup grated Parmesan cheese
  Adds umami, saltiness, and a crispy topping when baked.
• ½ teaspoon salt and ¼ teaspoon black pepper
  Simple seasonings that enhance all other flavors.
• ½ teaspoon paprika (optional)
  Provides a hint of warmth and vibrant color.
• ½ cup sour cream
  Creates a silky texture and subtle tang that rounds out the richness.

Step-by-Step Instructions

Follow these simple steps to create the perfect cheesy casserole:

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a medium-sized casserole dish with butter or non-stick spray.

2. Cook the Pasta

Boil the pasta in salted water until al dente, about 1-2 minutes less than package instructions. Drain and set aside.

3. Sauté the Aromatics

In a large saucepan, melt the butter over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Stir in the minced garlic and sauté for another minute.

4. Make the Roux

Sprinkle the flour over the sautéed mixture. Stir constantly for about 1-2 minutes, until the flour is fully incorporated and slightly golden.

5. Add the Milk

Gradually whisk in the milk, ensuring no lumps form. Cook for 4-5 minutes until the sauce thickens and coats the back of a spoon.

6. Melt the Cheeses

Reduce heat to low. Stir in the cheddar, mozzarella, and Parmesan, reserving a bit of each for the topping. Mix until melted and smooth.

7. Season and Enrich

Add the salt, pepper, paprika (if using), and sour cream. Stir well to combine.

8. Combine Pasta and Sauce

Add the cooked pasta to the cheese sauce and mix until fully coated.

9. Assemble the Casserole

Transfer the mixture to the prepared baking dish. Top with the remaining cheeses and sprinkle with the seasoned breadcrumbs.

10. Bake

Bake uncovered for 20-25 minutes, or until the top is golden and bubbly.

11. Rest and Serve

Let the casserole rest for 5-10 minutes before serving to allow the flavors to settle and the cheese to thicken.

Pro Tips for Perfection

• Undercook your pasta slightly: It will continue cooking in the oven and retain a better texture.
• Use freshly grated cheese: Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
• Mix in extras: Add cooked chicken, sautéed mushrooms, or steamed broccoli to make it a one-dish meal.
• Make ahead: Assemble up to a day in advance and refrigerate. Add 5–10 extra minutes to the baking time if chilled.

Serving Suggestions

Serve your cheesy casserole with:

• A crisp green salad with a tangy vinaigrette to balance the richness.
• Garlic bread or a rustic loaf for scooping up every bit of sauce.
• Steamed green beans or roasted vegetables for a well-rounded meal.
