Ingredients

Mornay Sauce

  • 2 cups whole milk
  • 2 Tablespoon butter
  • 2 Tablespoon all-purpose flour
  • 1 cup shredded sharp white cheddar or gruyere cheese
  • ¼-1/2 cup freshly grated Parmigiano-Reggiano or Pecorino-Romano cheese
  • Pinch of freshly grated nutmeg
  • Few dashes of hot sauce
  • Salt & pepper to taste

Sandwiches

  • 4 slices thick bread like Texas toast
  • 1 pound roasted turkey thickly sliced
  • 2 roma tomatoes sliced
  • ¾ cup sharp white cheddar or gruyere cheese
  • ¼ cup freshly grated Parmigiano-Reggiano or Pecorino-Romano cheese
  • 8 slices thick cut bacon cooked until crisp
  • Freshly chopped parsley for sprinkling on top
  • Paprika for sprinkling on top

Instructions

  • Heat milk in the microwave for 90 seconds.
  • In a large pan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute.
  • Gradually whisk in the hot milk. Cook until the sauce starts to simmer and is thickened, whisking almost constantly, about 3-5 minutes.
  • Remove from the heat and whisk in cheese until melted. Season with nutmeg, salt, pepper, and hot sauce, to taste.
  • Set oven to broil. Arrange tomato slices on a baking sheet and drizzle with a little oil and sprinkle with salt and pepper. Broil for 1-2 minutes per side until slightly charred.
  • Butter bread slices and place on foil-lined baking sheets. Toast under the broiler for 1-2 minutes, then flip and toast the other side.
  • Top toasted bread with the turkey, then tomato, then sauce, then sprinkle with additional cheese and broil for 2-3 minutes. Transfer to plates and top with bacon. Sprinkle with parsley or chives.

Notes

  • The sauce can be made ahead and refrigerated overnight, then rewarmed.
  • This is not a sandwich that stores or reheats well, but if you do have leftovers, store them in an airtight container and reheat them in a 350ºF oven until warmed through.
