  • 1 pound elbow macaroni, cooked
  • 4 cups whole milk
  • 7 tablespoons unsalted butter
  • ½ cup all purpose flour
  • ½ tablespoon salt
  • 8 ounces cheddar cheese
  • 4 ounces Pecorino Romano cheese
  • Two 6 ounce cans of crab meat
  • ¼ cup breadcrumbs


  • Cook pasta in a pot of salted water and drain. Set aside.
  • To make a bechamel sauce, melt butter in a pan over medium heat, just until it melts.
  • Add flour and whisk together with butter for 3-4 minutes, until it turns a light golden color. 
  • Increase temperature to medium-high and slowly add milk while whisking continuously. Cook for about 5 minutes, until sauce has thickened so it coats the back of a spoon.
  • Preheat oven to 425℉.
  • Add both cheeses to the bechamel sauce and stir with a spoon until thoroughly mixed.
  • In your sauce pot or a large bowl, stir cooked pasta together with bechamel cheese sauce and crab meat until mixed well. 
  • Transfer crab mac & cheese to a baking dish and sprinkle the top with breadcrumbs. Bake for 30-40 minutes. Let cool a few minutes. Serve as a main dish, or as a side to steak or chicken.
