A simple, hearty breakfast casserole combining savory sausage, gooey cheese, and fluffy eggs baked to perfection. Perfect for busy mornings or weekend brunches.

Ingredients

Scale
  • 1 pound ground breakfast sausage (mild or spicy)
  • 10 large eggs (room temperature)
  • 1 cup whole milk or half-and-half (240 ml)
  • 1 ½ cups shredded sharp cheddar cheese (170 g)
  • 1 cup shredded mozzarella cheese (115 g)
  • 4 cups cubed day-old French bread or brioche (about 67 slices), crusts removed
  • ½ cup finely chopped yellow or white onion (optional)
  • 1 teaspoon garlic powder
  • ½ teaspoon smoked paprika
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • Butter or cooking spray (for greasing the baking dish)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray.
  2. In a medium skillet over medium heat, crumble and cook the ground breakfast sausage until browned and cooked through, about 7-8 minutes. Drain excess fat if needed and set aside to cool slightly.
  3. Optional: In the same skillet, add chopped onion and cook for 3-4 minutes until translucent. Mix onions with cooked sausage.
  4. In a large bowl, whisk together eggs and milk until smooth. Stir in garlic powder, smoked paprika, salt, and black pepper. Taste and adjust seasoning if needed.
  5. Add cubed bread and the cooked sausage-onion mixture to the egg mixture. Stir gently to coat the bread well. Let sit for about 5 minutes to soak up the custard.
  6. Spread half of the soaked bread and sausage mixture evenly in the greased baking dish. Sprinkle ¾ cup shredded sharp cheddar and ½ cup shredded mozzarella over the layer.
  7. Top with the remaining soaked bread mixture and finish with the remaining cheese on top.
  8. Bake in the preheated oven for 40-45 minutes, or until the top is golden brown and a knife inserted in the center comes out clean. The edges should be bubbling and crispy.
  9. Let the casserole rest for 5-10 minutes before serving to help it set.

Notes

Use day-old bread to prevent sogginess. Drain excess sausage fat to avoid greasiness. Let casserole rest before serving for clean slices. Assemble the night before and refrigerate for easy morning baking. Cover with foil if cheese browns too quickly.
