Equipment:
- Large skillet
- Mixing bowls
- 9×13-inch baking dish
- Whisk
- Measuring cups and spoons
- Spatula or wooden spoon
- Oven
Ingredients:
- 1 lb ground chicken sausage or turkey sausage
- 8 large eggs
- 2 cups milk (whole or 2%)
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 bell pepper, diced
- 1 small onion, diced
- 3 cups cubed bread (French or sourdough)
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp paprika
- Salt and pepper to taste
- 2 tbsp olive oil (for cooking veggies)
- Optional: fresh parsley or green onions for garnish
Instructions:
- Preheat the oven: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish and set it aside.
- Cook the sausage: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the ground sausage, cooking until browned and crumbled. Remove from the skillet and set aside.
- Sauté the vegetables: Using the same skillet, add another tablespoon of olive oil. Sauté the diced bell pepper and onion until softened, about 5 minutes. Remove from heat.
- Prepare the egg mixture: In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, paprika, salt, and pepper until well combined.
- Assemble the casserole:
- Spread the cubed bread evenly in the prepared baking dish.
- Layer the cooked sausage and sautéed vegetables on top.
- Sprinkle half of the cheddar and mozzarella cheeses over the vegetables.
- Pour the egg mixture evenly over the bread and toppings, ensuring all the bread is soaked.
- Sprinkle the remaining cheese on top.
- Refrigerate or bake:
- Make ahead: Cover the dish with plastic wrap and refrigerate overnight.
- Bake immediately: Let the casserole sit for 10-15 minutes to allow the bread to absorb the egg mixture.
- Bake the casserole: Bake uncovered for 40-45 minutes, or until the eggs are set and the top is golden brown. If baking from the refrigerator, add 10 extra minutes of cooking time.
- Serve: Allow the casserole to rest for 5-10 minutes before cutting into squares. Garnish with fresh parsley or green onions, if desired.
