Ingredients
- 5 large croissants, torn into large chunks
- 1 pound ground sausage, cooked and drained
- 1 cup shredded cheddar cheese
- 6 large eggs
- 2 cups whole milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Grease a 9×13-inch baking dish with cooking spray or butter.
- Layer torn croissants evenly in the dish.
- Sprinkle cooked sausage over the croissants.
- Add shredded cheese, spreading it evenly across the dish.
- In a large bowl, whisk together eggs, milk, salt, pepper, garlic powder, and onion powder.
- Pour the egg mixture slowly over the croissant layers, ensuring all pieces are covered.
- Gently press down with a spatula so croissants absorb the liquid.
- Cover with foil and refrigerate overnight or for at least 6 hours.
- In the morning, preheat oven to 350°F (175°C).
- Uncover and bake for 45 minutes, or until golden brown on top and set in the center.
- Let cool for 10 minutes, garnish with fresh parsley, and serve warm.
Notes
- Use day-old croissants for better texture; fresh ones may turn soggy.
- Broil for 1–2 minutes at the end if a crispier top is desired.
- Can be made vegetarian by omitting sausage or using plant-based alternatives.
- Dish is freezer-friendly both before and after baking.
