The cheese is what makes this sing. Sharp cheddar from a block melts better than pre-shredded (which has anti-caking agents). For 20 servings, Costco or Sam’s Club are your best bets for quantity and quality. I always grab an extra pound of cheddar—it disappears fast at gatherings. The pasta should be slightly undercooked before baking to avoid mushiness.
No sharp cheddar? Colby or Monterey Jack work but may need extra salt. Swap whole milk for 2% in a pinch, but don’t go lower—fat is flavor here. Out of Dijon? Regular mustard at half the amount. The Worcestershire adds depth, but soy sauce works too if that’s all you’ve got. For the breadcrumbs, panko gives the best crunch, but crushed saltines are a decent backup.
This holds beautifully on a buffet for 2-3 hours—stir occasionally and add a splash of milk if it thickens too much. Leftovers keep 4-5 days refrigerated or freeze for 3 months. Reheat covered with foil, then uncover to crisp the top.

Step-by-Step Instructions for Community Barbecue Mac and Cheese
This method ensures a creamy, crowd-pleasing bake with perfect texture every time.
Step 1: Cook the Elbow Macaroni Al Dente
Bring a large pot of salted water to a rolling boil. Add the 4 lb Elbow Macaroni and cook for 1 minute less than package directions for al dente texture. You want the pasta slightly underdone as it will finish cooking in the oven.
Drain the macaroni in a colander and rinse briefly with cool water to stop the cooking process. Don’t rinse too thoroughly—you want some starch to remain to help the sauce cling. Transfer to a large bowl and toss with 1 tablespoon of the 1.5 lb Unsalted Butter to prevent sticking.
Step 2: Prepare the Creamy Cheese Sauce
In a large pot over medium heat, melt the remaining 1.5 lb Unsalted Butter (about 2¾ cups). Once melted, whisk in the 1.5 cups All-Purpose Flour to create a smooth roux. Cook for 2-3 minutes, stirring constantly, until the mixture turns a light golden color and smells slightly nutty.
Slowly pour in the 2 cups Whole Milk and 4 cups Heavy Cream, whisking continuously to prevent lumps. Stir in the 3 tbsp Dijon Mustard, 2 tbsp Garlic Powder, 2 tbsp Onion Powder, 2 tbsp Salt, 1 tbsp Ground Black Pepper, and 2 tbsp Worcestershire Sauce. Bring to a gentle simmer and cook for 5 minutes until slightly thickened.
Remove from heat and gradually add the 5 lb Sharp Cheddar Cheese, shredded, stirring until completely melted and smooth. The sauce should coat the back of a spoon and have a velvety texture.
Step 3: Combine Pasta and Sauce
Pour the cheese sauce over the cooked elbow macaroni in the large bowl. Using a silicone spatula, gently fold everything together until the pasta is evenly coated. Be thorough but avoid overmixing, which can break the pasta.
Taste and adjust seasoning if needed. The sauce should be rich and creamy, with a balanced flavor from the cheese and spices. If it seems too thick, add a splash of milk to reach the desired consistency.
Step 4: Add the Crispy Topping and Bake
Transfer the macaroni and cheese mixture to a large baking dish (or two smaller ones for easier serving). In a small bowl, melt 4 tablespoons of butter and mix with the 3 cups Panko Breadcrumbs until evenly coated. Sprinkle this mixture evenly over the top of the macaroni and cheese.
Bake in a preheated 375°F oven for 20-25 minutes until the topping is golden brown and the edges are bubbling. For extra crispiness, broil for the last 1-2 minutes, watching closely to prevent burning.
Remove from the oven and let it rest for 10 minutes before serving. This allows the sauce to thicken slightly and makes it easier to portion. Serve warm for the creamiest texture.
Pro Tips For Making Community Barbecue Mac And Cheese
- Undercook the Pasta: Boil the elbow macaroni 1-2 minutes less than package instructions—it’ll finish cooking in the creamy sauce without turning mushy. I learned this the hard way after serving gluey mac and cheese to a crowd.
- Grate Your Own Cheese: Skip the pre-shredded sharp cheddar; it’s coated in anti-caking agents that make the sauce grainy. A block of cheese and 5 minutes with a grater guarantees a silky texture.
- Temper the Dairy: Let the whole milk and heavy cream sit at room temp for 15 minutes before mixing with the cheese. Cold dairy can cause the sauce to seize up, and nobody wants lumpy mac and cheese at a barbecue.
- Butter the Dish: Grease your baking dish with some of that unsalted butter before adding the macaroni—it prevents sticking and adds a rich layer of flavor. My grandmother swore by this, and she never had to scrape her dish clean.
Storing and Reheating This Dish
Refrigerator Storage
Let this dish cool for no more than 2 hours before transferring to shallow, airtight containers. I use 9×13 inch glass baking dishes with tight lids. Store at 40°F or below for up to 4 days. The flavors deepen overnight, making leftovers even more delicious. ❄️
Freezer Storage
Portion into freezer-safe containers, leaving 1 inch headspace for expansion. This bake freezes well for up to 3 months. I recommend quart-size freezer bags for easier storage and quicker thawing. Label with the date to keep track of freshness.
Stovetop Reheating
Transfer a portion to a saucepan and add ¼ cup milk or cream to restore creaminess. Heat over medium-low heat for 8-10 minutes, stirring frequently. The sauce will thicken as it warms, so add more liquid if needed. 🔥
Oven Reheating
Cover your baking dish with foil and reheat at 350°F for 20-25 minutes. Uncover and bake for an additional 5-10 minutes to crisp the topping. This method works best for large batches.
Microwave Reheating
For quick single servings, microwave covered with a damp paper towel. Use 50% power for 2-3 minutes, stir, then continue in 30-second intervals until heated through. Add a splash of milk if it looks dry.
