Macaroni and Cheese Recipe for 30 People: Crowd-Pleasing Creamy Bake

Feeding a crowd doesn’t mean sacrificing quality, and this baked macaroni and cheese proves it. I developed this recipe for large gatherings, ensuring every bite delivers that creamy, comforting richness people expect.

The secret lies in a velvety cheese sauce made with sharp cheddar and Gruyère, blended with a touch of mustard for depth. Scaling for 30 servings requires precise ratios, but the method remains just as simple as any home-cooked version.

Baked until golden and bubbling, this dish emerges with a crisp top layer and an ultra-creamy center. It’s the kind of meal that disappears fast, leaving only empty dishes and satisfied guests.

Perfect for potlucks, family reunions, or community events. This recipe delivers consistency and flavor at scale.

Ingredients for Macaroni and Cheese Recipe for 30 People

Feeding thirty requires bold flavors and precise quantities. These ingredients deliver both.

The cheese selection is non-negotiable for optimal quality. Sharp cheddar and Gruyère provide the perfect balance of melt and depth. Whole Foods or Costco offer these in bulk quantities suitable for large-scale recipes. Always purchase blocks rather than pre-shredded to avoid anti-caking agents that can make the sauce grainy. The Parmesan should be Parmigiano-Reggiano for authentic flavor.

Substitutions must maintain the integrity of the dish. Monterey Jack can replace half the cheddar if needed, though the flavor profile will be milder. Half-and-half works in place of heavy cream at half the quantity, but the sauce may be slightly less rich. For the topping, regular breadcrumbs can be used, though Panko provides superior texture. Pre-shredded cheese should be avoided as it contains additives that prevent smooth melting.

Store all dairy products at 40°F or below until ready to use. The cheese sauce can be prepared 1 day in advance and refrigerated. Once baked, the dish holds at serving temperature for 2-3 hours in a chafing dish. Leftovers keep for 5 days refrigerated or can be frozen for 3 months.

Step-by-Step Instructions for Macaroni and Cheese for 30

Master this technique for a silky, rich bake that serves a crowd with ease.

Step 1: Cook and Drain the Elbow Macaroni

Bring a large stockpot of water to a rolling boil and add the 5 lb Elbow Macaroni. Stir occasionally to prevent sticking. Cook for 1 minute less than package directions—you want it al dente because it will finish cooking in the oven.

Drain the pasta in a colander and immediately rinse with cold water to stop the cooking process. This prevents overcooking and keeps the pasta firm. Shake off excess water but don’t dry it completely—a light film of moisture helps the cheese sauce cling.

Return the pasta to the pot and toss with 2 tablespoons of the 2 lb Unsalted Butter to prevent clumping while you prepare the sauce. The butter should melt and coat the pasta evenly, creating a glossy sheen.

Step 2: Prepare the Creamy Cheese Sauce

In a separate large, heavy-bottomed pot, melt the remaining unsalted butter over medium heat. Once foaming subsides, whisk in the 1.5 cups All-Purpose Flour to create a roux. Cook for 2-3 minutes, stirring constantly, until the mixture turns a light golden brown and smells nutty.

Gradually whisk in the 2 cups Whole Milk and 4 cups Heavy Cream, ensuring no lumps form. This is a large quantity, so add it in stages to maintain a smooth consistency. The mixture will thicken noticeably as it heats.

Stir in the 2 tbsp Garlic Powder, 2 tbsp Onion Powder, 2 tbsp Salt, 1 tbsp Black Pepper, 2 tbsp Dry Mustard, and 0.5 cup Dijon Mustard. Once fully incorporated, reduce heat to low and begin adding the cheese in batches.

Add the 7.5 lb Sharp Cheddar Cheese and 3.5 lb Gruyère Cheese a handful at a time, stirring until each addition is fully melted and smooth before adding more. This prevents the sauce from breaking and ensures a velvety texture.

Step 3: Combine Pasta and Sauce

Pour the cheese sauce over the cooked Elbow Macaroni in the stockpot. Using a large silicone spatula, fold the pasta and sauce together gently but thoroughly, ensuring every piece is evenly coated. The sauce should cling to the pasta with a glossy, thick consistency.

Let the mixture sit for 5 minutes off heat to allow the pasta to absorb some of the sauce. This step ensures the final dish is creamy rather than soupy. Stir once more before transferring to baking dishes.

Step 4: Top with Breadcrumbs and Bake

Divide the macaroni and cheese evenly among two large baking dishes (or one extra-large half-sheet pan). Sprinkle the 4 cups Panko Breadcrumbs evenly over the top, then finish with the 1.5 lb Parmesan Cheese. The breadcrumbs should form a thin, even layer that will crisp up beautifully.

Bake at 375°F for 20-25 minutes, until the top is golden brown and the edges are bubbling. Rotate the dishes halfway through for even browning. The aroma should be rich and nutty, with visible cheese pull when tested with a fork.

Let the dish rest for 10 minutes before serving to allow the sauce to set slightly. This ensures clean portions when scooping.

Wine and Beer Pairings for This Dish

Crisp White Wines

A dry Riesling from Washington State cuts through the richness beautifully with its bright acidity and citrus notes. I love Chateau Ste. Michelle—it’s widely available at New Seasons Market and pairs perfectly with the sharp cheddar. The slight mineral quality refreshes your palate between bites. 🍷

Buttery Chardonnays

For those who prefer a fuller-bodied white, a California Chardonnay with buttery notes complements the creamy sauce. Try Kendall-Jackson Vintner’s Reserve—its oaky richness stands up to the Gruyère without overpowering the dish.

Light Red Options

A light red like Pinot Noir from Oregon works surprisingly well. I grab Eyrie Vineyards from my local Portland shop. Its earthy notes and bright acidity balance the dish’s richness without clashing with the cheese flavors.

Craft Beer Pairings

A crisp pilsner like Breakside Brewery’s Portland-made pilsner cleanses your palate with its clean finish. The carbonation cuts through the creaminess, while the subtle hop bitterness contrasts the dish’s richness. 🍺

Amber Ales

For beer lovers, a caramel-forward amber ale such as Deschutes Mirror Pond adds a malty sweetness that pairs well with the toasted breadcrumb topping. The balance of hops and malt enhances the dish’s savory notes.

Non-Alcoholic

Sparkling apple cider from Portland’s own Portland Cider Company offers a festive, alcohol-free option. Its effervescence and natural sweetness complement the creamy, cheesy flavors beautifully.
