Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 60 minutes
• Total Time: 1 hour 20 minutes
• Servings: 6-8
• Yield: 1 casserole
• Dietary Type: Varies depending on added ingredients – can be dairy free with substitutions.

Ingredients

• 1 lb breakfast sausage
• 10 eggs
• 3 cups milk
• 2 teaspoons dry mustard
• 8 ounces cheddar cheese or 8 ounces colby-monterey jack cheese, shredded
• 6 cups bread, cubed (stale bread works best!)
• Salt and pepper to taste
• Optional add-in ideas:
  • Sliced mushrooms
  • Chopped tomato
  • Chopped bell pepper
  • Chopped green onion
  • Precooked potato chunks
  • Green chili

Equipment Needed

• 9×13 inch casserole dish
• Large bowl
• Skillet
• Whisk
• Measuring cups and spoons

Instructions

1. Preheat your oven to 325 degrees Fahrenheit.
2. Cook the breakfast sausage in a skillet according to the package directions. Be sure to crumble the sausage as it cooks. Once cooked through, drain off any excess grease.
3. In a large bowl, combine the eggs, milk, dry mustard, pepper, and salt. Whisk thoroughly until everything is well combined and slightly frothy. This ensures a light and airy casserole.
4. Lay half of the cubed bread in the bottom of a greased 9×13 inch casserole dish. If you don’t have cooking spray, a little butter will do the trick.
5. Add half of the cheese and half of the cooked sausage to the casserole dish. Also add half of any of the optional ingredients you are using, distributing them evenly.
6. Repeat the layer: Spread the remaining bread cubes over the sausage and cheese, then top with the rest of the cheese, sausage, and optional ingredients.
7. Pour the egg mixture evenly over the top of the casserole, making sure to saturate all the bread cubes. Gently press down with a spoon if necessary to ensure the bread absorbs the liquid.
8. Bake in the preheated oven for approximately 1 hour, or until the eggs are set. A knife inserted into the center should come out clean.
9. If the top of the casserole starts to brown too quickly, you can cover it loosely with aluminum foil during the last 15-20 minutes of baking.
10. Let stand for 10 minutes before serving.

Expert Tips & Tricks

• Use stale bread: Day-old bread, or even bread that’s been lightly toasted, will absorb the egg mixture better and prevent the casserole from becoming soggy.
• Make it ahead: This casserole is perfect for making ahead! Assemble it the night before, cover it tightly, and store it in the refrigerator. In the morning, simply bake as directed (you may need to add 10-15 minutes to the baking time).
• Spice it up: For a little extra heat, add a pinch of red pepper flakes to the egg mixture or use a spicy breakfast sausage.
• Cheese choices: Feel free to experiment with different cheeses. Pepper jack, mozzarella, or even a smoky gouda would be delicious.
• Vegetarian option: Substitute the sausage with crumbled vegetarian sausage or a combination of sautéed vegetables like mushrooms, spinach, and onions.
• Doneness check: The casserole is done when a knife inserted into the center comes out clean. The edges should be slightly puffed and golden brown. If the center is still jiggly, continue baking for a few more minutes.
• Prevent soggy casserole: Avoid adding too many wet ingredients. If using tomatoes, drain them well before adding them to the casserole.

Serving & Storage Suggestions

Serve the breakfast casserole warm, straight from the oven. It’s delicious on its own, or you can pair it with a side of fresh fruit, yogurt, or a dollop of sour cream or salsa.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.

Reheating: Reheat individual portions in the microwave or bake in a preheated oven at 350 degrees Fahrenheit until warmed through.

Freezing: You can also freeze the casserole for longer storage. Let it cool completely, then cut it into individual portions and wrap them tightly in plastic wrap and then foil. Frozen casserole can be stored for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
