Ingredients

• 6 large eggs — Eggs provide the protein base and help set the casserole.
• 2 cups whole milk — For a creamy texture; substitute with almond or oat milk for dairy-free.
• 1 tsp salt — Enhances all the flavors.
• 1/2 tsp black pepper — Adds mild heat and balance.
• 4 cups cubed bread — Day-old or slightly stale bread soaks up the egg mixture well.
• 1 1/2 cups shredded cheddar cheese — Use your favorite cheese or a blend for variety.
• 1/2 cup cooked breakfast sausage, crumbled — Swap with cooked bacon, ham, or a plant-based sausage.
• 1/2 cup diced bell peppers — Adds sweetness and color; you can omit or substitute with spinach or mushrooms.
• 1/4 cup chopped green onions — Offers a mild onion flavor; chives work well too.
• 1 tsp dried Italian herbs — Optional for added aroma; substitute with fresh herbs if preferred.

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
2. In a large mixing bowl, whisk together the eggs, whole milk, salt, black pepper, and dried Italian herbs until fully combined.
3. Spread the cubed bread evenly across the bottom of the prepared baking dish to create a base layer.
4. Distribute the cooked sausage, diced bell peppers, and chopped green onions evenly over the bread layer.
5. Sprinkle half of the shredded cheddar cheese over the toppings.
6. Pour the egg mixture slowly over all the ingredients to thoroughly soak the bread.
7. Top the casserole with the remaining cheese to form a cheesy crust while baking.
8. Bake uncovered for 40 to 45 minutes, or until the casserole is set in the center and golden on top.
9. Let it cool for a few minutes before slicing and serving.

Expert Tips

Use day-old bread to ensure it soaks up the custard properly without becoming mushy. If your casserole isn’t fully set after baking, cover it loosely with foil and bake an additional 5-10 minutes. Make this casserole the night before and refrigerate for an easy reheat in the morning. Scale the recipe easily by doubling or halving the ingredients depending on your crowd size.

Storage

Store any leftovers covered in the refrigerator for up to 4 days. To freeze, wrap portions tightly and freeze for up to 2 months. Reheat in the oven or microwave until warmed through.

Variations

• Vegan: Use plant-based eggs and cheese substitutes, with vegan sausage alternatives and non-dairy milk.
• Gluten-Free: Replace bread with gluten-free bread cubes or hash browns.
• Dairy-Free: Substitute milk and cheese with your favorite non-dairy options.
• Low-Carb: Swap bread for cauliflower rice or omit for a crustless dish with extra veggies.
