Baked Mac And Cheese Casserole Recipe

Who doesn't love ooey gooey, cheese-covered macaroni noodles, especially with a crispy breadcrumb topping? Mac and cheese is a classic side dish that has a seat at any holiday's table. While it's perfectly fine to make your mac and cheese on the stovetop, baking it in a casserole dish makes the cheese a little thicker, and crisps up a golden brown panko topping. 

This baked mac and cheese recipe shared by developer Michelle McGlinn melts together mozzarella, fontina, and white cheddar cheese for an irresistibly delicious dish. The 3 rich cheeses are joined by fresh thyme and garlic, then topped with buttery breadcrumbs for a perfectly cozy casserole. This mac and cheese is easy to customize, too: add chorizo for a spicy kick, or shredded chicken for added protein. Mac and cheese is surprisingly easy to make, and comes together in just a few active minutes, leaving the rest of the work to the oven. It's the perfect side dish for any meal, and is sure to please guests of any age. Keep reading to find out this mac and cheese casserole recipe.

Ingredients needed to make baked mac and cheese casserole

First things first, you need macaroni. It's not totally necessary to use elbow macaroni in mac and cheese, so if you have rotini or fusilli on hand, give those a try instead. You'll want to use around 8 ounces, or about half of a standard box of noodles. 

For the sauce, you'll need butter, flour, milk, and a couple different cheeses. Any milk will work fine, but whole milk will give you the thickest and richest sauce. This recipe calls for mozzarella, white cheddar, and fontina — all deliciously melty and balanced in flavor. If you can't find fontina, try Gruyère — an equally melty cheese. If you'd prefer regular cheddar to white, just swap it for mild cheddar.

To finish the sauce, you'll just need garlic powder, fresh or dried thyme, salt, pepper, and panko breadcrumbs. Panko will be a little crunchier than standard, fine breadcrumbs, but you can swap them in a pinch.

Make the panko topping

Cook the pasta about a minute less than al dente, so that it cooks to perfection in the oven. You can make the panko topping after making the sauce, but it is easiest to throw together the topping before getting into the sauce. Just mix together 2 tablespoons of melted butter, a pinch of salt, and the panko breadcrumbs, until the panko is slightly moistened. We aren't looking for a super wet crumb, just enough to help it brown in the oven. Set aside. 

Whisk together the sauce

Most macaroni sauces will start with a roux to help it thicken. To make the roux, melt the remaining 4 tablespoons of butter in a pot, then whisk the flour into the melted butter, until smooth. The flour will try to clump together — just keep whisking until smooth. Don't allow the roux to burn, or the sauce will have a bitter taste.

Pour in the milk 1 cup at a time, whisking as you pour to avoid scalding, and break up any clumps. The milk will thicken slightly from the flour, but will still be thin after 3 minutes. Stir in the cheeses one at a time, melting each one down before adding the next. The fontina cubes will take the longest to melt, so add the thyme, garlic powder, salt, and pepper to taste while melting the fontina.

Add the pasta, bake, then serve

Add the cooked and drained pasta to the sauce, then stir until the pasta is completely coated. Season to taste with salt and pepper, then carefully pour the mixture into a casserole dish. This will fit in most casserole dishes, but will best fit a 9-by-11-inch dish. Sprinkle your prepared panko mixture on top, then add a few thyme sprigs. Bake uncovered for around 30 minutes to crisp the panko, and thicken the sauce.

This mac and cheese is delicious on its own, or when paired with spicy chorizo or baked chicken. If serving this as a side dish, serve it alongside steaks, fried chicken, or pork chops. Leftovers can be stored in an airtight container, and reheated in the microwave, though you might notice some dryness in the noodles. If you plan on having leftovers, add more milk to the sauce to ensure better reheating.
