Ingredients

  • 1 lb lean ground beef
  • 1/2 cup onion, diced
  • 1 garlic clove, diced
  • 1 teaspoon kosher salt
  • 1/2 teaspoon ground black pepper
  • 1/2 cup whole milk
  • 4 ounces cheddar cheese
  • 2 ounces cream cheese
  • 1 tablespoon all-purpose flour
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon ground mustard
  • 3 large eggs, seperated

Method

  • Preheat oven to 400 degrees.
  • In an oven-safe skillet (cast iron is great!) brown ground beef with the onion, garlic, 1 teaspoons Kosher salt & black pepper. Set aside to cool while you prepare the egg/cheese mixture.
  • In a medium glass bowl, heat milk for 45-60 seconds or until steaming. Add the cheddar cheese, cream cheese, 1/2 teaspoons Kosher salt & mustard. Stir with a whisk until the cheese is melted & fully incorporated.
  • Seperate the three eggs, add the yolks to the cheese mixture & placing the whites in a seperated bowl.
  • Add 1 tablespoons flour to the cheese mixture also, and whisk to combine the flour & yolks with the egg mixture until homogeneous.
  • Whisk egg whites until stiff peaks form--I do this in my stand mixer. Fold egg whites into the cheese mixture.
  • Pour half of the cheese mixture into the pan holding the ground beef mixture. Fold together. Top with the remaining cheese mixture.
  • Bake at 400 degrees for about 20 minutes, or until golden brown & set. It will be a bit jiggly, but not runny. You can check with a knife.
  • Allow to cool for ten minutes before cutting. :).
