Ingredients
For this mac and cheese, the quality of each component matters. The elbow pasta provides the perfect bite‑size pocket for sauce, while the pimiento peppers contribute a gentle, smoky sweetness.

Main Ingredients
- 12 oz elbow macaroni
- 1 cup roasted pimiento peppers, diced
Cheese Sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all‑purpose flour
- 2 cups whole milk, warmed
- 1 cup shredded sharp cheddar cheese
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
Topping & Seasonings
- ½ cup panko breadcrumbs
- 2 tablespoons melted butter (for topping)
- ¼ teaspoon smoked paprika
- ¼ teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
Each ingredient plays a purpose: the butter‑flour roux creates a velvety base, the warmed milk prevents lumps, and the cheese trio balances sharpness, stretch, and umami. Pimientos add a subtle smoky sweetness that lifts the whole dish, while the seasoned breadcrumb topping delivers a satisfying crunch. Together they form a cohesive, comforting casserole that’s both hearty and elegant.
Step-by-Step Instructions

Cooking the Pasta
Bring a large pot of salted water to a rolling boil. Add the elbow macaroni and cook al dente, about 7‑8 minutes, stirring occasionally. Al dente pasta holds its shape during baking and absorbs the sauce without becoming mushy. Drain, reserving ½ cup of the cooking water, and set the pasta aside.
Preparing the Cheese Sauce
- Make a roux. In a medium saucepan over medium heat, melt 2 tablespoons unsalted butter. Once foamy, whisk in 2 tablespoons all‑purpose flour and cook for 1‑2 minutes, stirring constantly, until the mixture turns a light golden color. This step eliminates raw flour taste and forms the thickening backbone of the sauce.
- Incorporate milk. Gradually whisk in 2 cups whole milk, warmed. Keep the heat at medium‑low and stir until the sauce thickens and coats the back of a spoon, about 4‑5 minutes. If the sauce seems too thick, add a splash of the reserved pasta water to reach a silky consistency.
- Blend the cheeses. Reduce heat to low and stir in 1 cup shredded sharp cheddar, 1 cup shredded mozzarella, and ½ cup grated Parmesan. Continue stirring until every cheese has melted into a glossy, homogenous sauce. The combination of sharp, melty, and nutty cheeses creates depth and stretch.
- Season and add pimientos. Fold in the 1 cup diced roasted pimiento peppers, then season with ¼ teaspoon smoked paprika, ¼ teaspoon garlic powder, and salt and pepper to taste. The pimientos should be evenly distributed, providing bursts of flavor throughout the casserole.
Assembling the Casserole
In a large mixing bowl, combine the drained pasta with the cheese‑pimiento sauce, tossing gently to coat each piece. Transfer the mixture to a greased 9‑x‑13‑inch baking dish, spreading it into an even layer. This ensures uniform baking and prevents dry spots.
Creating the Crunchy Topping
In a small bowl, mix ½ cup panko breadcrumbs with 2 tablespoons melted butter until the crumbs are lightly coated. Sprinkle the breadcrumb mixture evenly over the top of the casserole. The butter helps the crumbs brown and become crisp during baking.
Baking to Perfection
Preheat the oven to 375°F (190°C). Place the assembled dish on the middle rack and bake uncovered for 20‑25 minutes, or until the top is golden brown and the sauce is bubbling around the edges. A visual cue of a deep amber crust signals that the mac and cheese is ready. Remove from the oven and let it rest for 5 minutes before serving; this allows the sauce to thicken slightly and makes portioning cleaner.
Tips & Tricks
Perfecting the Recipe
Use freshly roasted pimientos. Roasting the peppers yourself intensifies their smoky flavor and yields a tender texture that blends beautifully into the sauce.
Don’t over‑cook the pasta. Al dente pasta absorbs the sauce without becoming mushy during the bake, preserving a pleasant bite.
Reserve pasta water. Adding a splash of the starchy water to the sauce can rescue a too‑thick mixture and helps the sauce cling to the noodles.
Cover for the first half. If you notice the breadcrumbs browning too quickly, loosely cover the dish with foil for the first 12 minutes, then uncover to finish.
Flavor Enhancements
Stir in a tablespoon of Dijon mustard into the cheese sauce for a subtle tang, or finish the baked casserole with a drizzle of hot honey for a sweet‑spicy contrast. A pinch of cayenne or red‑pepper flakes adds a gentle heat without overwhelming the cheese.
Common Mistakes to Avoid
Avoid boiling the sauce; high heat can cause the cheese to separate and become grainy. Also, don’t skip the resting time after baking—cutting too early releases steam and makes the dish watery. Finally, resist the urge to add too much extra liquid; the sauce should be thick enough to cling to the pasta.
Pro Tips
Grate cheese fresh. Pre‑grated cheese contains anti‑caking agents that can affect meltability. Freshly grated cheese yields a smoother sauce.
Season each layer. Lightly salt the pasta water and taste the sauce before baking. Layered seasoning builds depth.
Use a heavy‑bottomed pan. Even heat distribution prevents scorching of the roux and ensures a uniform sauce.
Let the dish cool slightly. A 5‑minute rest after baking allows the cheese to set, making clean slices and reducing mess.
Variations
Ingredient Swaps
Swap elbow macaroni for cavatappi or shells if you prefer a different shape. Replace pimiento peppers with roasted red bell peppers or fire‑roasted green chilies for a milder or spicier profile. For a richer flavor, incorporate a handful of crumbled blue cheese or smoked gouda alongside the cheddar.
Dietary Adjustments
Use gluten‑free pasta and gluten‑free panko for a safe option. Substitute dairy‑free cheese blends and oat milk for a vegan version, and add nutritional yeast for extra umami. For a low‑carb take, replace the pasta with spiralized zucchini or cauliflower “rice” and adjust the breadcrumb topping with crushed pork rinds.
Serving Suggestions
Serve the casserole with a crisp arugula salad dressed in lemon vinaigrette to cut through the richness. A side of roasted garlic bread or buttery biscuits is perfect for sopping up any extra sauce. For a festive touch, garnish with chopped fresh parsley and a sprinkle of extra Parmesan just before plating.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then transfer portions into airtight containers. Store in the refrigerator for up to 4 days. For longer keeping, place the entire dish in a freezer‑safe container, cover tightly with plastic wrap followed by foil, and freeze for up to 3 months. Proper sealing prevents freezer burn and preserves the creamy texture.
Reheating Instructions
Reheat leftovers in a preheated 350°F (175°C) oven, covered with foil, for 15‑20 minutes until the interior is hot and the topping regains its crunch. For a quicker option, microwave individual servings on medium power for 2‑3 minutes, stirring halfway and adding a splash of milk or broth to restore moisture.
