Ingredients:
- 1 lb ground breakfast sausage
- 1 small yellow onion, finely diced
- 1 red bell pepper, diced
- 2 cloves garlic, minced
- 7 large croissants, torn into 2-inch chunks
- 2 cups sharp cheddar cheese, freshly shredded
- 0.5 cup Parmesan cheese, freshly grated
- 8 large eggs
- 2 cups whole milk
- 1 cup heavy cream
- 1 tsp kosher salt
- 0.5 tsp black pepper
- 0.5 tsp dry mustard powder
- 0.25 tsp ground nutmeg
Instructions:
- In a large skillet over medium-high heat, brown the ground sausage for 5 minutes until no pink remains, breaking it into small crumbles.
- Add the diced onion and red bell pepper to the skillet; sauté for approximately 5 minutes until softened.
- Stir in the minced garlic and cook for 1 minute until fragrant and softened.
- Prepare the bread. Tear 7 large croissants into 2 inch chunks and place half in a greased 9x13 dish.
- Layer the fillings. Spread the sausage mixture over the croissants, then top with 1 cup sharp cheddar cheese.
- Finish layering. Add the remaining croissant chunks and the rest of the cheddar and 0.5 cup Parmesan cheese.
- Whisk the custard. Combine 8 large eggs, 2 cups whole milk, 1 cup heavy cream, 1 tsp salt, 0.5 tsp pepper, 0.5 tsp dry mustard, and 0.25 tsp nutmeg.
- Pour the egg mixture evenly over the casserole. Press down lightly to submerge the bread. Cover with foil and refrigerate for at least 6 hours or overnight.
- Bake the casserole. Bake at 350°F (175°C) for 45 minutes until golden and the center is set.
