Quick Recipe Overview

Ingredients

• 1 lb breakfast sausage (mild or spicy, crumbled)
• 6 large eggs
• 2 cups milk (whole or 2%)
• 6 slices bread (cubed, white or sourdough)
• 1 cup shredded cheddar or Swiss cheese (optional – omit for no cheese version)
• ½ tsp salt
• ¼ tsp black pepper
• ½ tsp dry mustard or Dijon (optional for flavor boost)
• 2 green onions, sliced (optional garnish)
• Butter or cooking spray (for greasing)

Step-by-Step Instructions

• 1. Cook the Sausage : In a skillet over medium heat, cook sausage until browned and crumbly. Drain excess fat and let cool slightly.
• 2. Prepare the Egg Mixture : In a large bowl, whisk together eggs, milk, salt, pepper, and mustard until smooth and well combined.
• 3. Assemble the Casserole : Grease a 9×13-inch baking dish. Layer bread cubes evenly on the bottom. Sprinkle sausage and cheese (if using) over the bread. Pour the egg mixture evenly over the top, pressing lightly to ensure the bread absorbs the liquid.
• 4. Refrigerate Overnight : Cover tightly with plastic wrap or foil and refrigerate for at least 8 hours, or overnight, to let the flavors soak in.
• 5. Bake to Golden Perfection : Preheat oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature for 20 minutes. Bake uncovered for 40–45 minutes, or until the eggs are set and the top is golden brown.
• 6. Serve and Enjoy : Let rest for 5 minutes before slicing. Garnish with green onions or herbs and serve warm.

Nutrition Facts

Healthier or Dietary Alternatives

To make this egg breakfast casserole overnight a bit lighter, use turkey sausage or chicken sausage instead of pork. Swap whole milk for skim or unsweetened almond milk, and skip the cheese or use reduced-fat options.

For a gluten-free version, replace regular bread with your favorite GF loaf. You can also add veggies like bell peppers, spinach, or mushrooms to increase fiber and nutrition while keeping the flavor hearty and satisfying.

Serving Suggestions

• Serve with a side of fresh fruit or orange slices for balance.
• Pair with crispy roasted potatoes or a green salad for brunch.
• Add a drizzle of hot sauce or a dollop of salsa for extra flavor.
