Description

Overnight breakfast casserole brings comfort to your morning table with minimal effort and maximum flavor. Hearty layers of eggs, cheese, and sausage bake into a delightful dish that makes breakfast feel like a special occasion.


Ingredients

Scale

Primary Protein:

  • 1 pound sausage
  • 8 large eggs

Base Ingredients:

  • 4 cups day-old bread cubes
  • 2 cups whole milk
  • 2 cups shredded sharp cheddar cheese

Supporting Vegetables and Seasonings:

  • 1 cup diced bell peppers
  • 1 cup chopped onion
  • Salt
  • Pepper

Instructions

  1. Prepare your mise en place by dicing 1 cup bell peppers and 1 cup onions into uniform small pieces for even cooking and distribution.
  2. Heat a large skillet over medium-high heat and cook 1 pound of sausage, breaking it into small crumbles until no pink remains, approximately 7-8 minutes.
  3. Crack 8 large eggs into a spacious mixing bowl and pour 2 cups whole milk, whisking vigorously until the mixture becomes light and aerated.
  4. Add 2 cups shredded sharp cheddar cheese, cooked sausage, diced bell peppers, chopped onions, 1 teaspoon salt, and ½ teaspoon black pepper to your egg mixture, stirring gently to combine.
  5. Tear 4 cups day-old bread cubes into the bowl and fold them carefully, ensuring each bread piece gets coated with the egg mixture.
  6. Transfer the entire mixture into a generously greased 9×13 inch baking dish, smoothing the top to create an even layer.
  7. Cover the casserole with plastic wrap and refrigerate for 8-12 hours, allowing flavors to meld and bread to absorb the liquid.
  8. Remove casserole from refrigerator 30 minutes before baking to reduce temperature shock.
  9. Preheat your oven to 350°F and bake uncovered for 50-55 minutes, until the top turns golden brown and the center becomes firm and puffy.

Notes

  • Chop vegetables finely to ensure even distribution and better texture throughout the casserole.
  • Allow the sausage to cool slightly before mixing with eggs to prevent scrambling and maintain a smooth consistency.
  • For a lighter version, swap whole milk for skim milk and use turkey sausage instead of pork sausage.
  • Customize the casserole by adding your favorite herbs like thyme or rosemary for extra flavor depth.
