6 slices French baguette

1 stick unsalted butter

5 1/2 C. milk

1/2 C. flour

2 tsp. salt

1/4 tsp. pepper

1/4 tsp. nutmeg

1/4 tsp. cayenne

4 1/2 C. grated sharp Cheddar cheese (18 oz.)

2 C. grated Gruyere (8 oz.)

1 1/4 C. grated Pecorino Romano (5 oz.)

1 lb. elbow or shell pasta

 

Heat the oven to 375 degrees. Butter a 3 1/2-quart casserole dish. Make bread crumbs from the baguette in a food processor or blender. Mix the crumbs with 2 T. of melted butter and set aside. Warm the milk over medium heat. In a separate pan, melt the remaining butter until bubbly. Whisk in the flour and cook, stirring for 1 minute. Then, still whisking, add the warm milk a bit at a time. Continue cooking, stirring constantly, until the mixture bubbles and thickens. Remove it from the heat. Stir in the salt, pepper, nutmeg, cayenne, and cheeses. Set aside. Cook the pasta until slightly underdone, then rinse it under cold water. Combine it with the cheese sauce and pour it into the buttered casserole dish. Sprinkle with the buttered bread crumbs and bake for about 30 minutes, until the mixture bubbles and the crumbs are brown. Let the dish set for 5 minutes before serving.
