Recipe Information
Ingredients
- 10 large eggs
- 1 cup whole milk
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 pound ground breakfast sausage
- 1 medium, diced yellow onion
- 1 medium, diced red bell pepper
- 2 cups baby spinach
- 2 cups shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 4 cups cubed bread (e.g., French or sourdough)
- 1 for greasing butter or nonstick cooking spray
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with butter or nonstick cooking spray.
In a large skillet over medium heat, cook the ground breakfast sausage, breaking it apart with a wooden spoon, until browned and fully cooked, about 8-10 minutes. Remove the cooked sausage from the skillet and set it aside.
In the same skillet, add the diced onion and red bell pepper. Sauté until softened, about 5-6 minutes. Add the baby spinach and cook just until wilted, about 1-2 minutes. Remove from heat.
In a large mixing bowl, whisk together the eggs, whole milk, salt, and black pepper until well combined.
Add the cubed bread, cooked sausage, sautéed vegetables, 1 1/2 cups of shredded cheddar cheese, and 1/2 cup of shredded mozzarella cheese to the egg mixture. Stir gently to combine, ensuring the bread absorbs the liquid evenly.
Pour the mixture into the prepared casserole dish, spreading it out evenly. Top with the remaining cheddar and mozzarella cheese.
Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Then, remove the foil and bake for an additional 15 minutes, or until the casserole is set and the cheese is golden and bubbly.
Remove the casserole from the oven and let it cool for 5-10 minutes before slicing and serving. Enjoy this dish warm for breakfast, lunch, dinner, or brunch!
