Ingredients
  

Main Ingredients
  • 1 lb Sage Breakfast Sausage crumbled
  • 6-8 slices day-old white sandwich bread cubed
  • 8 Large Eggs
  • 2 cups whole milk
  • 1.5 cups Shredded Sharp Cheddar Cheese
  • ½ cup Onion finely chopped
  • ½ cup Green Bell Pepper finely chopped
Seasoning
  • Salt to taste
  • Black Pepper to taste
  • 1 teaspoon Dry Mustard optional
  • Red Pepper Flakes a pinch (optional)

Equipment

  • Large skillet
  • 9x13 inch baking dish
  • Large bowl
  • Whisk

Method
 

Preparation
  1. Cook the crumbled breakfast sausage in a large skillet over medium-high heat until browned, then drain excess grease.
  2. Optionally, sauté the chopped onion and bell pepper in a little sausage grease or oil until softened.
Assembly
  1. Grease a 9x13 inch baking dish, then spread the cubed bread evenly across the bottom.
  2. Sprinkle the cooked sausage and sautéed vegetables over the bread, then top with shredded cheese.
Egg Mixture & Chilling
  1. Whisk together eggs, milk, salt, pepper, and dry mustard in a large bowl until well combined.
  2. Pour the egg mixture over the ingredients in the baking dish, ensuring the bread is saturated.
  3. Cover and refrigerate for at least 4 hours or overnight.
Baking & Serving
  1. Preheat oven to 350°F (175°C), then let the casserole sit at room temperature for 20-30 minutes.
  2. Bake for 45-55 minutes until puffed, golden brown, and a knife inserted in the center comes out clean.
  3. Rest for 5-10 minutes before slicing and serving to allow it to set properly.

Notes

For best results, allow the casserole to chill overnight. This lets the flavors meld and the bread fully absorb the egg mixture, resulting in a more tender and flavorful bake.
