Main Ingredients

  • 1 lb Breakfast Sausage adds savory, hearty flavor
  • 8 large Jumbo Eggs bind everything together for a fluffy texture
  • 1 tsp Salt enhances all flavors
  • 1 tsp Black Pepper adds a subtle kick
  • 1/2 tsp Cayenne Pepper for a hint of warmth (optional)
  • 1 tsp Ground Mustard compliments the eggs beautifully
  • 1 tsp Dried Sage gives that lovely herbal note
  • 1 tsp Dried Chives adds earthy flavor
  • 2 cups Half-and-Half makes it extra creamy (substitute with milk if needed)
  • 1 cup Sharp Cheddar Cheese for classic breakfast flavor
  • 1 cup White Cheddar Cheese adds depth and creaminess
  • 5 cups Butter Bread provides the base that soaks up all the goodness

Instructions
 

Preparation

  • Gather all ingredients and preheat your oven to 350°F (175°C).
  • Cube the butter bread into bite-sized pieces.
  • Cook the breakfast sausage in a skillet until browned, then drain excess fat.

Cooking/Assembling

  • In a big bowl, whisk together the eggs, half-and-half, salt, black pepper, cayenne pepper, ground mustard, sage, and chives.
  • Add the cooked sausage, cheeses, and cubed bread. Gently fold everything until well combined.
  • Pour the mixture into a greased 9x13 baking dish, cover, and refrigerate overnight.

Serving

  • The next morning, uncover the dish and bake for about 45 minutes or until puffed and golden brown.
  • Let it rest for a few minutes before serving. Enjoy warm!

Notes

Substitute any cooked meat for the sausage, like turkey or ham, for a different flavor. For extra fluffiness, whip the egg mixture until frothy before combining. This dish can be stored in the fridge and reheated for quick breakfasts.
