Best-Ever Macaroni And Cheese - cooking recipe

Ingredients

1/2 cup panko breadcrumbs
1 teaspoon melted butter
1/2 cup butter
1/2 cup flour
5 cups milk
1/2 teaspoon dry mustard
1/4 teaspoon white pepper
1/4 teaspoon cayenne pepper
1/8 teaspoon nutmeg
1 teaspoon salt
1 bay leaf
4 cups shredded cheddar cheese, divided
3 cups shredded swiss gruyere cheese
1 lb pasta shells, cooked according to package directions (or LARGE elbow macaroni)
1/2 cup heavy cream

Preparation

Heat the oven to 350 degrees.
Toss the panko bread crumbs with melted butter on a small baking pan. Toast the bread crumbs until lightly browned about 10 minutes. Set aside to cool.
In a large saucepan, heat the butter over medium heat until melted, then stir in the flour. Heat and stir until the mixture is smooth and bubbling about 2 minutes. Remove from heat and whisk in the milk. Add the seasonings (next 6 ingredients).
Heat and stir to boiling, then reduce heat to a low simmer and cook, stirring occasionally, for 30 minutes. Remove the bay leaf.
Stir in 3 cups of the cheddar cheese and all the Gruyere until melted. Pour the sauce over the cooked macaroni in a large bowl, stirring until all the macaroni is coated.
Pour the macaroni into a well-greased 9x13 baking pan. Drizzle heavy cream around the edges of the casserole. Sprinkle on the remaining 1 cup of cheddar cheese. Top with the panko crumbs and cover the casserole.
Bake 20 minutes. Remove the cover and bake an additional 10 minutes.
