Ingredients
  

Main Ingredients

  • 1 pound breakfast sausage can substitute with turkey or veggie sausage
  • 8 large eggs
  • 2 cups milk almond milk for a dairy-free alternative
  • 8 slices bread day-old or whole grain/gluten-free
  • 2 cups shredded cheese Cheddar or blend of cheeses

Seasonings

  • 1 teaspoon garlic powder for an extra kick
  • 1 teaspoon onion powder
  • Salt and pepper to taste

Instructions
 

Preparation

  • In a skillet over medium heat, crumble and cook the breakfast sausage until browned and cooked through, about 5-7 minutes. Drain excess fat and set aside.
  • In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until well combined.
  • Grease a 9x13 inch baking dish. Layer the bread cubes evenly at the bottom. Sprinkle the cooked sausage over the bread, followed by the shredded cheese.
  • Pour the egg mixture over the layers, pressing the bread down gently to absorb the liquid. Cover the dish with foil and refrigerate overnight.

Baking

  • The next morning, preheat your oven to 350°F (175°C).
  • Bake the casserole (covered with foil) for 30 minutes. Remove the foil and bake for an additional 15 minutes until the top is golden and bubbly.
  • Let it cool for a few minutes before slicing into squares—serve warm and enjoy your hearty breakfast!

Notes

For a healthier option, consider using egg whites, substituting half the sausage with vegetables, or using low-fat cheese. Store leftovers in an airtight container in the fridge for up to 3 days, or freeze individual portions.
