Print Recipe


  • 1 pound elbow macaroni
  • 3 tablespoons butter divided
  • 3 tablespoons flour divided
  • 1 tablespoon powdered mustard divided
  • 3 cups milk divided
  • 1/2 teaspoon paprika divided
  • 1 large egg whisked and divided
  • 1 teaspoon kosher salt divided
  • Fresh black pepper

For the Bacon and Onion Mac and Cheese:

  • 1/4 cup yellow onion finely diced (sautéed optional)
  • ¼ cup cooked bacon crumbles
  • 8 ounces sharp cheddar shredded
  • 4 slices sharp cheddar

For the Garlic Parmesan Mac and Cheese:

  • 1/4 cup grated Parmesan Cheese
  • 8 ounces shredded Mozzarella Cheese
  • 1 teaspoon McCormick Garlic Powder
  • 4 slices Mozzarella Cheese


  • 3 tablespoons butter
  • 1 cup panko bread crumbs
  • 2 cups French’s French Fried Onions


  • Preheat oven to 350 degrees F.
  • In a large pot of boiling, salted water cook the pasta to al dente.
  • While the pasta is cooking, we will make our two sauces in two separate small saucepans. In each saucepan, melt 1 ½ tablespoons butter. Whisk in 1 ½ tablespoons flour and ½ tablespoon mustard powder, whisking constantly for 2-3 minutes. Stir in 1 ½ cups milk and ¼ teaspoon paprika. Reduce both to a simmer for 6-8 minutes.
  • Add half the egg to each sauce mixture, whisking to combine. In one pot, stir in the ingredients (except for the sliced cheese) for the Bacon and Onion Mac and Cheese (onion, bacon, and shredded cheddar) and in the other saucepan stir in the ingredients (except for the sliced cheese) for the Garlic Parmesan Mac and Cheese (grated parm, shredded mozzarella, and garlic powder). Stir to combine and season both with salt and pepper to taste,
  • Add half the macaroni to each mixture and stir to coat.
  • Pour half of the bacon onion macaroni mixture into its half of the casserole dish and top with two slices of cheddar cheese. Top with the remaining half of the macaroni mixture and then top with two more slices of cheddar. Repeat with the Garlic Parmesan Macaroni mixture, using sliced mozzarella this time.
  • In a separate small saute pan, melt the butter for the topping and toss in the bread crumbs to coat. Remove from the heat and stir in the French Fried Onions. Top both sides of macaroni mixture with the topping.
  • Bake for 30 minutes. Remove from oven and rest for five minutes before serving.
