Baked Mac and Cheese Recipe with Block Cheese: Crispy Crust, Pillowy Elbow Pasta Bliss

This baked mac and cheese recipe with block cheese delivers the ultimate comfort food experience—crispy golden edges, a creamy center, and perfectly tender elbow pasta that holds up to every bite.

The secret lies in freshly grating sharp cheddar blocks for maximum flavor and texture, a technique that transforms ordinary mac and cheese into something restaurant-worthy. I developed this method after years of testing, ensuring the cheese melts smoothly while maintaining that coveted crispy crust.

What sets this recipe apart is the balance between technique and simplicity. You'll start with al dente elbow pasta, then combine it with a rich cheese sauce that's been thickened just right.

The block cheese approach eliminates the need for pre-shredded varieties that often contain anti-caking agents, resulting in a sauce that's velvety and luxurious. Baking at the perfect temperature creates that crispy crust we all love while keeping the interior pillowy and rich.

By the time it emerges from the oven, you'll have a dish that's equal parts indulgent and satisfying—golden edges that shatter with each bite, creamy cheese that coats every strand of pasta, and a texture that's impossible to resist.

The aroma alone will have everyone gathering around your table, and the first forkful will confirm why this has become my go-to comfort food recipe.

This recipe works beautifully as a main dish for family dinners or as an impressive appetizer for gatherings. The leftovers reheat wonderfully, making it perfect for meal prep. Let's get started on creating this ultimate baked mac and cheese that will become a household favorite.

Ingredients for baked mac and cheese recipe with block cheese

Freshly grated sharp cheddar, al dente elbow pasta, and a crispy golden crust—this is comfort food at its finest.

The cheese makes or breaks this dish—sharp cheddar blocks are non-negotiable. Whole Foods or local cheese shops carry the best varieties, but any block labeled 'sharp' will work. Look for cheese with good marbling and a vibrant orange color. I always grab 2 pounds—enough for that ultra-creamy sauce. Pro tip: grate the cheese yourself (the box grater works best) right before mixing to avoid clumping. Skip the pre-shredded stuff—it's loaded with anti-caking agents that make the sauce grainy. For the pasta, De Cecco or Barilla brands hold up perfectly when baked.

No sharp cheddar? Monterey Jack or Gruyère add delicious variations—just balance flavors with extra mustard powder. Running low on heavy cream? Half-and-half works in a pinch, but the sauce won't be as rich. The onion and garlic are your flavor base—don't skip sautéing them until soft. For that perfect crispy crust, the butter + panko combo is key. Mix them together before sprinkling on top—this creates pockets of air that toast beautifully. The olive oil is for greasing, but don't skimp on the butter on top—it's what gives you that golden, shatterable crust we all crave.

This tastes even better the next day—3-4 days in the fridge, covered tightly. For meal prep, portion into individual dishes and reheat at 350°F for 15 minutes. Freezes beautifully for up to 2 months—just thaw overnight in the fridge before reheating. The crust gets crispy again when reheated, so don't worry about it getting soggy. Leftovers? Package them in airtight containers and store with a paper towel on top to absorb any moisture.

Step-by-step instructions for baked mac and cheese with block cheese

Here's how to create the ultimate baked mac and cheese with that perfect crispy crust and creamy center.

Bring a large pot of water to a rolling boil and add 1½ pounds of elbow pasta. Stir immediately to prevent sticking. Cook for 1 minute less than the package instructions suggest—you want al dente pasta that'll finish cooking in the oven. Reserve 1 cup of pasta water before draining, as this starchy liquid is essential for creating a silky sauce.

Drain the pasta and return it to the pot. Toss with 1 tablespoon of extra-virgin olive oil to prevent sticking and keep it from drying out. The pasta should be hot but not steaming when you add it to the cheese mixture—this helps create that perfect creamy texture.

In a large saucepan, melt ½ cup of unsalted butter over medium heat. Add 1 finely diced yellow onion and cook for 5 minutes until softened. Stir in 4 minced garlic cloves and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter.

Whisk in ¼ cup of all-purpose flour and cook for 1-2 minutes until the mixture forms a light roux. Gradually pour in 1½ cups of heavy cream and 1 cup of whole milk, whisking constantly to prevent lumps. Bring to a gentle simmer and cook for 5 minutes until slightly thickened.

While the sauce simmers, shred 2 pounds of sharp cheddar cheese block using a box grater or food processor. The cheese should be finely shredded—large chunks won't melt smoothly. Add the shredded cheese to the saucepan along with 2 teaspoons of salt, ½ teaspoon of black pepper, and ½ teaspoon of mustard powder.

Stir constantly over low heat until the cheese melts completely and the sauce becomes thick and glossy. If the sauce looks too thick, whisk in 2-3 tablespoons of reserved pasta water to reach a smooth, pourable consistency. Remove from heat and add the cooked elbow pasta, tossing gently to coat each strand completely.

Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with olive oil. Spread the mac and cheese mixture evenly into the dish, pressing down gently to compact the pasta. In a small bowl, mix ½ cup of panko breadcrumbs with 2 tablespoons of melted butter.

Sprinkle the breadcrumb mixture evenly over the top of the mac and cheese, pressing down lightly with a spatula to ensure good contact. Bake for 20-25 minutes until the top is deep golden brown and bubbly, and the edges are crispy. The center should still be creamy—this is what makes baked mac and cheese so special.

Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly and the flavors to meld together. The mac and cheese will be hot and bubbly, with a crispy golden crust on top and creamy, cheesy layers beneath.

Serve immediately with a side of crusty bread or a simple green salad. The contrast between the crispy top and the creamy interior makes every bite unforgettable. And don't forget to save any leftovers—they taste even better the next day!

Pro cooking tips for this recipe

Cheese Grating Mastery

Freshly grating your own sharp cheddar blocks is non-negotiable for that velvety texture. Use a box grater or food processor with the shredding blade—never pre-shredded cheese, which contains anti-caking agents that make the sauce grainy.

For 2 pounds of cheese, work in batches to avoid clumping. I like to pulse the cheese in the food processor for 3-4 seconds per batch to get uniform shreds. 🧀

Pasta Timing Secrets

Cook your elbow pasta 1 minute less than package instructions recommend—it'll finish cooking in the oven. Reserve 1 cup pasta water before draining; this starchy liquid is liquid gold for adjusting sauce consistency.

Toss the hot pasta with 1 tablespoon olive oil immediately after draining to prevent sticking and maintain moisture for that creamy texture.

Sauce Thickening Hacks

The roux technique is your secret weapon. Cook ¼ cup flour in ½ cup butter for exactly 1-2 minutes—any longer and you'll get a bitter flavor. Gradually whisk in 1½ cups heavy cream and 1 cup milk while maintaining heat.
