Mac N Cheese Recipe for a Crowd: Creamy Baked Feast in One Pan

This baked mac and cheese has been my go-to for family gatherings since I first decoded my grandmother’s vague handwritten notes.

What makes this version special is its ability to scale perfectly for large groups while maintaining that creamy texture everyone loves. The secret lies in a precise ratio of cheese to pasta and a baking technique that prevents dryness.

You’ll end up with a golden, bubbling dish that serves a crowd without compromising on quality. The sauce stays velvety, and every bite delivers that comforting richness we all crave.

One pan, minimal effort, and a table full of happy eaters—that’s the beauty of this recipe.

The cheese is non-negotiable here. Sharp cheddar from the deli counter melts better than pre-shredded (which has anti-caking agents). Gruyere and Parmesan add that nutty depth—Whole Foods or Trader Joe’s have great blocks. For the vegetarian Worcestershire, Annie’s is the brand to grab. The pasta? Any short shape works, but elbow macaroni is classic for a reason.

No Gruyere? Fontina or Monterey Jack at the same amount work fine. Swap the milk for half-and-half if that’s what you’ve got (but don’t go lower than whole milk). Short on time? Pre-shredded cheese in a pinch—just expect a slightly grainier sauce. The mustard can be yellow if you don’t have Dijon, but the sharpness really balances the richness. Skip the topping if you’re feeling lazy (we won’t tell).

This reheats like a dream—tastes even better the next day once flavors meld. Keeps 4-5 days in the fridge, freezes for 3 months. Portion into foil pans for easy transport to potlucks (that’s how grandma did it).

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

Here’s the foolproof method I use to feed a crowd without breaking a sweat.

Step 1: Cook the Elbow Macaroni Perfectly Al Dente

Bring a large stockpot of salted water to a rolling boil. Add the 4 lb Elbow Macaroni and cook for 1 minute less than the package directs. You want it slightly underdone because it will finish cooking in the oven.

Stir occasionally to prevent sticking, and start testing for doneness at 8 minutes. The pasta should be tender but still have a slight bite when you taste it. Drain immediately and set aside—don’t rinse, as the starch helps the sauce cling.

Step 2: Make the Ultra-Creamy Cheese Sauce

In the same pot, melt the 1.5 cups Unsalted Butter over medium heat. Whisk in the 1.25 cups All-Purpose Flour and cook for 2 minutes until the mixture turns a light golden color and smells nutty. This roux is the backbone of your sauce.

Slowly pour in the 2 cups Whole Milk and 4 cups Heavy Cream, whisking constantly to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. Stir in the 3 tbsp Dijon Mustard, 2 tbsp Worcestershire Sauce, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 2 tbsp Salt, and 1 tbsp Ground Black Pepper.

Step 3: Melt in the Cheeses for Maximum Flavor

Reduce heat to low and gradually add the 5 lb Sharp Cheddar Cheese, 2 lb Gruyere Cheese, and 1 lb Parmesan Cheese, stirring constantly until each addition is fully melted. I add the cheeses in batches to prevent clumping and ensure a smooth, velvety texture.

Taste the sauce and adjust seasoning if needed. The cheese sauce should be rich and creamy, with a slight tang from the mustard and Worcestershire. If it’s too thick, thin it with a splash of milk or cream.

Step 4: Combine and Top with Panko Breadcrumbs

Add the drained Elbow Macaroni to the cheese sauce and stir until every piece is coated. Transfer the mixture to a large baking dish (or two if needed for your crowd). Sprinkle the 2 cups Panko Breadcrumbs evenly over the top for a crispy, golden finish.

At this point, you can cover and refrigerate until ready to bake, or proceed directly to the oven. The panko adds a delightful crunch that contrasts beautifully with the creamy pasta below.

Step 5: Bake Until Bubbly and Golden

Bake in a preheated 375°F oven for 20-25 minutes until the top is golden brown and the edges are bubbling. If the panko starts to brown too quickly, tent the dish with foil for the remaining time.

Let it rest for 5-10 minutes before serving. This allows the sauce to set slightly, making it easier to serve neat portions. The result is a creamy, dreamy mac n cheese that’s sure to impress even the pickiest eaters in your crowd.

Wine and Beer Pairings for This Recipe

Crisp Whites

A bright Sauvignon Blanc from New Zealand cuts through the richness with its citrusy acidity. I love Kim Crawford for its grapefruit notes that cleanse your palate between bites. Serve it slightly chilled for best results. 🍷

Buttery Chardonnays

For those who prefer a fuller-bodied white, a California Chardonnay like Kendall-Jackson complements the creamy sauce beautifully. The buttery notes mirror the dish’s richness without overpowering it.

Light Beers

A crisp pilsner such as Stella Artois offers a refreshing contrast to the cheesy depth. The light body and subtle hoppiness make it an easy-drinking choice for a crowd. 🍺

Amber Ales

An amber ale like Fat Tire brings caramel notes that pair surprisingly well with the sharp cheddar. The malty sweetness balances the dish’s savory elements perfectly.

Sparkling Options

For non-alcoholic pairings, a dry sparkling cider like Angry Orchard Crisp Apple works wonderfully. The bubbles and slight tartness cut through the creaminess just like wine would.
