Mac N Cheese Recipe For A Crowd: Baked Cheesy Layers for 12

Feeding a crowd doesn’t have to mean stress or compromise on quality. This baked mac and cheese delivers creamy, cheesy layers that will satisfy everyone at your table.

I developed this recipe after too many attempts at scaling up smaller versions resulted in dry or uneven dishes. The key is cooking the pasta al dente before baking and using a combination of cheeses for depth of flavor.

The result is a dish with a golden crust, tender noodles, and a sauce so rich it clings to every bite. It’s comfort food at its finest, designed to serve twelve without losing any of its homemade appeal.

Perfect for gatherings, potlucks, or family dinners where you want to make sure everyone leaves happy and full.

Ingredients for Mac N Cheese Recipe for a Crowd

Feeding twelve with rich, creamy layers requires just these pantry and dairy staples.

The cheeses make this dish. Sharp cheddar for punch, Gruyere for meltiness, and Parmesan for depth. Skip the pre-shredded stuff—it’s coated in anti-caking agents that make the sauce grainy. Whole Foods or Costco have great blocks at better prices than pre-shredded. For the milk and cream, full-fat is non-negotiable (trust me on this one).

No Gruyere? Fontina or Monterey Jack melt just as well. Swap the Dijon for regular mustard in a pinch—just add a pinch of cayenne for kick. The panko can be regular breadcrumbs, but the texture won’t be as crispy. For extra flavor, toast the panko in butter with a sprinkle of garlic powder before baking.

Assemble and refrigerate up to 24 hours before baking—perfect for get-ahead cooking. Leftovers keep 4-5 days in the fridge and reheat like a dream. Freeze portions for up to 3 months (thaw overnight before reheating).

Step-by-Step Instructions for Mac N Cheese for a Crowd

Making this for twelve is easier than you think with this simple, proven method.

Step 1: Cook the Elbow Macaroni Al Dente

Bring a large pot of salted water to a rolling boil and add the 2 lb Elbow Macaroni. Cook according to package directions for al dente, usually 1-2 minutes less than the suggested time.

Drain immediately and rinse briefly with cool water to stop the cooking process. This prevents the pasta from turning mushy when baked. Toss the drained pasta with a drizzle of olive oil to keep it from sticking together while you prepare the sauce.

Step 2: Make the Creamy Cheese Sauce

In a large pot, melt the 1 cup Unsalted Butter over medium heat. Once foaming, whisk in the 0.75 cup All-Purpose Flour to create a smooth roux. Cook for 1-2 minutes, stirring constantly, until the mixture turns a light golden color and smells slightly nutty.

Slowly whisk in the 2 cups Whole Milk and 2 cups Heavy Cream, ensuring no lumps form. Stir in the 2 tsp Salt, 1 tsp Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, and 2 tbsp Dijon Mustard. Bring to a gentle simmer for 3-5 minutes until the sauce thickens enough to coat the back of a spoon.

Reduce heat to low and gradually add the 2 lb Sharp Cheddar Cheese, 1 lb Gruyere Cheese, and 1 cup Parmesan Cheese, stirring constantly until each addition is fully melted and smooth. Taste and adjust seasoning if needed.

Step 3: Combine Pasta and Sauce

Pour the cooked elbow macaroni into the cheese sauce and stir until every piece is evenly coated. This is where the magic happens—the pasta soaks up the rich, velvety sauce. If the mixture seems too thick, add a splash of warm milk to loosen it slightly.

Step 4: Top with Panko Crust and Bake

Transfer the mac and cheese to a large greased baking dish (or two medium dishes). In a small bowl, mix the 2 cups Panko Breadcrumbs with the 1 tsp Paprika and sprinkle evenly over the top. The paprika adds a subtle smokiness and beautiful color.

Bake at 375°F for 20-25 minutes until the sauce is bubbling at the edges and the panko topping turns golden brown. For extra crispiness, broil for 1-2 minutes at the end, but watch closely to prevent burning.

Step 5: Rest and Serve

Let the dish rest for 10 minutes after removing from the oven. This allows the sauce to thicken slightly and makes serving easier. Scoop portions with a spatula, ensuring each serving has a good amount of the crispy panko topping.

The result should be creamy, cheesy perfection with a crunchy crust on top. The combination of sharp cheddar, nutty gruyere, and salty parmesan creates a depth of flavor that will have everyone asking for seconds.

Essential Equipment for This Recipe

Large Stockpot

A 5-6 quart stockpot is essential for cooking 2 lb of elbow macaroni evenly. I use my enamel-coated cast iron pot—it distributes heat beautifully and has enough capacity for the pasta to move freely. Anything smaller risks uneven cooking or boiling over.

Heavy Bottom Pot

For the cheese sauce, you need a heavy-bottomed pot (like my All-Clad 5-quart) to prevent scorching. A thin pot can cause the roux to burn or the sauce to stick. The heavy base gives you better control over medium heat for that perfect silky texture.

Whisk and Wooden Spoon

A sturdy whisk is non-negotiable for making the roux lump-free. I switch to a wooden spoon once the cheese starts melting to avoid scratching my pot. These two tools make all the difference in achieving that velvety sauce. 💪

Large Mixing Bowl

Combine pasta and sauce in a large mixing bowl before transferring to the baking dish. This ensures every noodle gets coated evenly. I use my stainless steel restaurant-style bowl—it’s big enough to handle the volume without spills.

Baking Dishes

Use a 9×13-inch baking dish or two 8×8-inch dishes for even baking. I prefer stoneware because it retains heat better than glass. Whatever you choose, make sure it’s at least 2 inches deep to hold all that cheesy goodness.

Cheese Grater

Freshly grated cheese melts better than pre-shredded. I swear by my box grater with multiple sides for different textures. It’s a small effort that pays off in creamier sauce and better flavor. 🧀
