Cooking Tips

  • Use 1 cup butter and 1 cup flour for the roux base.
  • Cook pasta in batches to prevent sticking.
  • Boil noodles 1 minute less than package instructions.
  • Use hotel pans for serving large crowds.

Choosing The Best Cheese For Big Batches

Primary Flavor Base

Sharp cheddar is the non-negotiable foundation for large batches. It delivers the bold, tangy flavor expected in mac and cheese. Mild cheddar often gets lost when scaled up. Always use extra sharp blocks for maximum impact.

Creamy Enhancers

Cheddar lacks moisture on its own. Mix in softer cheeses to create a velvety sauce that coats every noodle.

  • Gruyère: Adds a nutty, sophisticated taste.
  • Monterey Jack: Ensures a smooth, melting texture.
  • Colby: Provides a mild, buttery balance.
  • Smoked Gouda: Offers a deep, smoky depth for variation.

Buy Blocks, Not Bags

Never use pre-shredded cheese for crowds. Shredded cheese is coated in cellulose to prevent clumping. This anti-caking agent stops it from melting correctly. Your sauce will separate and turn gritty. Buy blocks and shred them yourself for best results.

Pan Selection

Shallow pans heat more evenly than deep dishes.

  • Disposable foil pans work well for potlucks and easy cleanup.

Topping And Serving

Top dishes with buttered cracker crumbs or Panko mixed with Parmesan.

Transfer baked pans to chafing dishes to keep food warm during long events.
