Ingredients for Sausage Breakfast Casserole
- 1 pound breakfast sausage (mild or spicy)
- 6 large eggs
- 2 cups whole milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 6 cups cubed day-old bread (French or sourdough)
- 2 cups shredded sharp cheddar cheese
- 1/2 cup chopped green onions
- Butter for greasing the baking dish
How to Make Sausage Breakfast Casserole
Step 1: Prepare the Sausage
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter.
- In a large skillet over medium heat, cook the breakfast sausage, breaking it up with a spoon, until browned and cooked through (about 6-8 minutes). Drain any excess fat.
Step 2: Layer the Casserole
- Spread cubed bread evenly over the bottom of your prepared baking dish.
- Sprinkle the cooked sausage over the bread, then layer with shredded cheddar cheese and chopped green onions.
Step 3: Whisk the Eggs
- In a large mixing bowl, whisk together eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
- Pour the egg mixture evenly over the layered bread, sausage, and cheese.
Step 4: Soak & Bake
- If time allows, cover and refrigerate the casserole for at least 30 minutes (or overnight) to let the bread soak up the egg mixture.
- Bake (uncovered) for 45-55 minutes, or until the center is set and the cheese is bubbly and golden brown.
- Let cool for 10 minutes before slicing. Serve warm and enjoy!
Sausage Breakfast Casserole Notes & Tips
- Use slightly stale or day-old bread so it holds up well and soaks in the custard without becoming soggy (learn why here).
- For an extra golden top, sprinkle a little extra cheese before baking.
- This casserole can be assembled up to 24 hours in advance, making it a lifesaver for entertaining (see more make-ahead tips).
Sausage Breakfast Casserole Variations
- Vegetarian: Skip the sausage and add sautéed mushrooms, spinach, and bell peppers.
- Gluten-Free: Use your favorite gluten-free bread instead of traditional bread.
- Spicy: Use hot sausage and add chopped jalapeños for a spicy kick.
