Macaroni And Cheese Recipe For 50 People: Crowd-Pleasing Creamy Batch

Feeding a crowd requires precision, and this mac and cheese delivers creamy results every time. I developed this recipe after catering a local Portland community event, testing it three times to perfect the scaling and texture.

The key lies in the cheese sauce ratio—enough to coat every noodle without becoming gluey. A blend of sharp cheddar and American cheese ensures smooth meltability and rich flavor that satisfies all 50 servings.

Cook the pasta al dente, then finish it in the sauce to absorb maximum creaminess. The result is a velvety, uniform dish that holds beautifully in chafing dishes for hours.

This method transforms simple ingredients into a professional-quality meal that impresses without stress. The proof is in the empty serving trays.

The cheese blend is critical here. Sharp cheddar from Tillamook or Cabot provides the bold flavor base, while American cheese (like Boar’s Head or Land O’Lakes) ensures that signature melt. Buy blocks and grate fresh—pre-shredded has anti-caking agents that make the sauce grainy. For the pasta, Barilla or De Cecco elbow macaroni holds up best when scaled this large.

No American cheese? Velveeta or mild cheddar can substitute, but expect slightly less creaminess. Swap Dijon for yellow mustard at the same amount. Missing nutmeg? Paprika adds color and mild warmth. For a richer sauce, add 1 cup cream cheese (at room temperature). If scaling down, keep the ratio: 2 parts cheddar to 1 part American for optimal melt.

This holds beautifully in chafing dishes for 2-3 hours. Store leftovers in shallow containers—cools faster and reheats more evenly. Keeps 4-5 days refrigerated, freezes for 3 months. Reheat gently with a splash of milk to restore creaminess.

Step-by-Step Instructions for Macaroni and Cheese for 50 People

Here’s the method. Straightforward, tested, works every time.

Step 1: Cook the Elbow Macaroni to Al Dente

Bring a large stockpot of water to a rolling boil and salt it generously with the 3 tbsp Salt. Add the 10 lb Elbow Macaroni and cook for 1 minute less than the package directs for al dente.

You want the pasta slightly undercooked because it will finish in the hot cheese sauce. Stir occasionally to prevent sticking. Drain the pasta in a colander but do not rinse—you need the starch for the sauce to cling properly.

Transfer the drained pasta to a large, lightly greased baking pan or hotel pan. This will hold your creation while you prepare the sauce.

Step 2: Prepare the Roux Base for Creaminess

In a large, heavy-bottomed pot, melt the 2 lb Unsalted Butter over medium heat. Once fully melted and foaming, whisk in the 2 cups All-Purpose Flour to form a smooth paste.

Cook the roux for 2-3 minutes, stirring constantly, until it turns a light golden color and smells nutty. This step removes the raw flour taste and builds the foundation for your sauce. Be careful not to let it brown too deeply, or the sauce may take on a bitter flavor.

Step 3: Build the Cheese Sauce Gradually

Slowly pour in the 4 cups Whole Milk and 4 cups Heavy Cream, whisking continuously to prevent lumps from forming. Bring the mixture to a gentle simmer over medium-low heat.

Once simmering, add the 0.5 cup Dijon Mustard, 3 tbsp Garlic Powder, 3 tbsp Onion Powder, 1 tbsp Ground Black Pepper, 1 tsp Ground Nutmeg, and 2 tbsp Dry Mustard Powder. Stir until fully incorporated.

Begin adding the cheeses in batches, starting with the 10 lb Sharp Cheddar Cheese and 5 lb American Cheese. Stir until each addition is fully melted and smooth before adding more. This gradual process ensures a velvety, lump-free sauce.

Step 4: Combine and Finish for Creamy Perfection

Pour the cheese sauce over the cooked elbow macaroni in the baking pan. Using a large spoon or spatula, fold the sauce and pasta together gently until every piece is evenly coated.

Taste and adjust seasoning if needed, though the cheeses should provide plenty of saltiness. If the mixture seems too thick, add a splash of warm milk to reach your desired consistency. The sauce should cling to the pasta but still be loose enough to serve easily.

Let the dish sit for 5-10 minutes before serving. This allows the flavors to meld and the sauce to thicken slightly, ensuring every serving is rich, creamy, and perfectly seasoned.

Make-Ahead Tips for This macaroni and cheese recipe for 50 people

Prep Ahead Strategy

You can cook the 10 lb Elbow Macaroni up to 24 hours in advance. Toss it with 2 tbsp olive oil to prevent sticking, then store it in a large container with a tight lid. I learned this trick catering that Portland community event—saves so much day-of stress. 💡

Sauce Separation

Make the cheese sauce completely, then let it cool before refrigerating in a separate container. The sauce will thicken as it chills. When ready to combine, gently reheat the sauce over low heat while stirring, then pour over the pasta.

Baking Option

For a crispy top, transfer the combined pasta and sauce to two large baking dishes. Cover with foil and refrigerate. Before serving, bake at 350°F for 20-25 minutes, then broil for 2-3 minutes with 2 cups breadcrumbs mixed with ¼ cup melted butter. ❄️

Chafing Dish Tips

If holding in chafing dishes, keep the heat on low-medium and stir every 30 minutes. Add ½ cup milk at a time if the sauce thickens too much. This method keeps it creamy for the full 2-3 hours.

Freezing Method

Portion leftovers into shallow containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating. I use New Seasons Market containers—they’re perfect for large batches.
