Main Ingredients

  • 1 lb breakfast sausage, mild
  • 1 small onion, diced
  • 1 bell pepper, red, diced
  • 8 large eggs
  • 1 cup whole milk
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 cup shredded cheddar cheese
  • 2 cups cubed stale sourdough bread
  • hot sauce for serving

Instructions
 

Preparation

  • Preheat oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  • In a large skillet, cook breakfast sausage until no longer pink, then drain excess grease.
  • Add diced onion and red bell pepper to the skillet with the sausage and cook until softened.
  • Spread the cubed sourdough bread evenly over the bottom of the greased baking dish.
  • Scatter the cooked sausage, onion, and bell pepper mixture over the bread layer.
  • Sprinkle half (½ cup) of the shredded cheddar cheese over the sausage mixture.

Baking

  • In a large bowl, whisk together eggs, whole milk, salt, and black pepper until well combined.
  • Carefully pour the egg mixture over all ingredients in the baking dish, ensuring they are submerged.
  • Sprinkle the remaining shredded cheddar cheese over the top.
  • Bake for 35-45 minutes until set, golden brown, and a knife inserted in the center comes out clean.

Serving

  • Let the casserole rest for 5-10 minutes before slicing and serving.
  • Serve with a dash of hot sauce, if desired.

Notes

For best results, use day-old or slightly stale bread to prevent the casserole from becoming soggy. You can also customize this bake with other vegetables like mushrooms or spinach.
