Ingredients

• 15 pounds elbow macaroni (uncooked)
• 3 gallons whole milk
• 2 gallons heavy cream
• 10 pounds sharp cheddar cheese, shredded
• 5 pounds mild cheddar cheese, shredded
• 2 pounds Parmesan cheese, grated
• 3 cups unsalted butter (6 sticks)
• 3 cups all-purpose flour
• 1/4 cup kosher salt, plus more to taste
• 2 tablespoons ground black pepper
• 2 tablespoons garlic powder (optional)
• 2 tablespoons dry mustard powder (optional, enhances cheese flavor)
• 2 cups panko breadcrumbs (optional, for topping)
• 2 tablespoons smoked paprika (optional, for topping)

Instructions

1. Cook the pasta: Bring a very large pot of salted water to a boil. Add the elbow macaroni in batches if needed and cook until just al dente (about 7 minutes). Drain well and rinse under warm water to stop cooking and prevent sticking. Set aside in a large container, lightly coated with oil to keep from clumping.
2. Prepare the cheese sauce (béchamel base): In a massive stockpot or divided into two large pots, melt the butter over medium heat. Once melted, whisk in the flour and cook for 2-3 minutes, stirring constantly, to form a roux. It should be bubbly but not browned.
3. Add milk and cream: Gradually whisk in the whole milk and heavy cream, stirring constantly to avoid lumps. Bring the mixture to a gentle simmer. Continue whisking until the sauce thickens to a creamy consistency, about 10-15 minutes.
4. Season the sauce: Stir in kosher salt, black pepper, garlic powder, and dry mustard powder (if using). Taste and adjust seasoning as needed.
5. Add cheeses: Remove the sauce from heat and gradually stir in the shredded sharp cheddar, mild cheddar, and Parmesan cheeses until fully melted and smooth. Keep the sauce warm on very low heat, stirring occasionally.
6. Combine pasta and sauce: In a very large mixing vessel or in batches, combine the cooked pasta with the cheese sauce, folding gently to coat all noodles evenly.
7. Transfer to serving pans: Portion the mac and cheese into large hotel pans or roasting pans. If desired, sprinkle the top evenly with panko breadcrumbs mixed with smoked paprika for a crunchy topping.
8. Bake (optional): For a baked version, preheat ovens to 350°F (175°C). Bake pans uncovered for 20-25 minutes until bubbly and golden on top. This step is optional but adds texture and warmth.
9. Serve: Keep warm until serving. If not serving immediately, cover pans tightly with foil and store as below.

Tips

• Cheese substitutions: Use a mix of cheeses that melt well, like Gruyère, Monterey Jack, or Fontina, if cheddar isn’t preferred. Avoid pre-shredded cheese with anti-caking agents, as it can affect melting.
• Make ahead: Prepare the cheese sauce and pasta separately a day in advance. Combine and bake or reheat on event day for best texture.
• Common mistake: Overcooking pasta causes mushiness. Aim for al dente and rinse immediately to halt cooking. Also, avoid overheating cheese sauce once cheese is added to prevent graininess.
• Scaling equipment: Use large stockpots and multiple pans to manage volume. Consider dividing the recipe into two or three batches for easier handling.

Serving Suggestions

Mac and cheese pairs well with a variety of sides and toppings to round out a large meal. For a crowd, consider serving alongside:

• Fresh green salads with vinaigrette to cut the richness
• Roasted or steamed vegetables like broccoli, green beans, or carrots
• Barbecue meats such as pulled pork, ribs, or grilled chicken
• Crusty bread or garlic bread for added texture
• Pickled vegetables or coleslaw for a tangy contrast

Variations

• Spicy mac and cheese: Add diced jalapeños or a dash of cayenne pepper to the cheese sauce for heat.
• Bacon mac and cheese: Fold in cooked, crumbled bacon or pancetta for smoky flavor.
• Vegetarian: Incorporate sautéed mushrooms, spinach, or roasted red peppers for added nutrition and color.
• Gluten-free: Use gluten-free pasta and substitute the flour in the roux with cornstarch or a gluten-free blend.

Storage and Reheating

Store leftover mac and cheese in airtight containers in the refrigerator for up to 3-4 days. When reheating, add a splash of milk or cream to loosen the sauce and warm gently on the stovetop over low heat or in a covered baking dish at 325°F (160°C) until heated through (about 20-30 minutes). Avoid high heat to prevent drying out or curdling the cheese sauce.

For longer storage, mac and cheese can be frozen for up to 2 months. Freeze in portioned airtight containers. Thaw overnight in the refrigerator before reheating as described above. Note that texture may slightly change after freezing.

Frequently Asked Questions

Can I prepare this mac and cheese recipe entirely ahead of time?

Yes. You can cook the pasta and prepare the cheese sauce separately up to 24 hours in advance. Combine and bake or reheat just before serving to maintain optimal texture and flavor.

What type of cheese works best for large batches?

Sharp cheddar is a classic choice for flavor and meltability. Mixing it with milder cheeses like mild cheddar or Monterey Jack balances richness. Parmesan adds a savory depth. Avoid cheeses that don’t melt smoothly, like fresh mozzarella or crumbly feta.

How do I avoid the cheese sauce becoming grainy?

Cook the roux properly and add milk gradually, whisking to prevent lumps. Remove the sauce from heat before adding cheese and stir gently until melted. Overheating or cooking cheese sauce at too high a temperature can cause graininess.

Can I bake the mac and cheese in advance and reheat it later?

Yes, you can bake it ahead and refrigerate. Reheat covered in the oven at 325°F (160°C) until warmed through, adding a little milk if it seems dry. This method helps maintain a creamy texture with a crispy top.

What equipment do I need to cook for 100 people?

Large stockpots, multiple hotel or roasting pans, and commercial-size mixing bowls are ideal. Industrial-sized ovens or multiple ovens speed up baking. If equipment is limited, divide the recipe into manageable batches.

How much mac and cheese should I plan per person?

Typically, allocate about 1 cup (approx. 6-8 ounces) of cooked mac and cheese per person as a main or 1/2 cup as a side. This recipe yields roughly 100 servings at 1 cup each, allowing for generous portions.

By following these detailed steps and tips, you can confidently prepare a large batch of creamy, delicious mac and cheese that will satisfy and impress a crowd of 100 guests.
