Ingredients

  • 1 tablespoon Unsalted Butter
  • 1 package English Muffins (6 English muffins; regular or gluten-free) (I used Udi’s Gluten Free White English Muffins)
  • 1 pound bulk/loose Breakfast Sausage
  • 1 cup grated Cheddar Cheese (mild or sharp)
  • 1 cup grated Mozzarella Cheese
  • 10 Eggs lightly beaten
  • 2 cups Half and Half
  • 1/2 teaspoon Kosher Salt
  • 1/4 teaspoon freshly ground Black Pepper

Instructions

  • In a large skillet over medium-high heat brown the sausage, breaking it into small pieces. Drain any excess fat and allow sausage to cool while preparing the remaining ingredients.
  • Lightly grease a 13-inch by 9-inch baking dish with the butter. Cut the English muffins into 1-inch cubes and spread them evenly in the prepared pan.
  • Spread half of the cooled sausage (it can be warm but not hot enough to begin to cook the other ingredients) evenly over the English muffin cubes. Sprinkle ½ cup of each type of cheese evenly on top.
  • In a medium mixing bowl combine the eggs, Half and Half, salt and pepper; whisk to fully combine. Pour evenly over the top of the casserole.
  • Sprinkle the remaining half of the sausage onto the casserole followed by the remaining cheese. Seal tightly and refrigerate overnight.  
  • The next morning: Preheat the oven to 350 degrees. Remove the casserole from the refrigerator 30 minutes prior to cooking. Cook for 35 minutes or until the casserole is lightly brown on top and set in the middle. Allow to sit for 10 minutes prior to slicing and serving.
