Step‑by‑Step Instructions for Easy Make-Ahead Breakfast Casserole
Step 1: Prepare the Baking Dish
Begin by greasing a 9×13-inch baking dish with butter or cooking spray to prevent sticking. Next, evenly layer the cubed day-old bread on the bottom of the dish, allowing the bread to act as the sturdy base for your Easy Make-Ahead Breakfast Casserole. Aim for an even distribution to ensure a perfect texture throughout.
Step 2: Add the Savory Ingredients
Sprinkle the cooked and crumbled breakfast sausage evenly over the cubed bread, followed by the chopped bell pepper and green onions. This flavorful layer will infuse the casserole with delicious savory notes when baked. Make sure to spread the ingredients evenly to ensure every bite of the casserole is packed with flavor.
Step 3: Cheese Layer
Generously top the sausage and vegetable mixture with shredded cheddar cheese, letting it create a gooey, melty topping. The cheese adds a rich, creamy element that complements the other ingredients beautifully. For an extra cheesy experience, don’t be shy about adding a little more than two cups if you’re a cheese lover!
Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together the six large eggs, two cups of whole milk, salt, and black pepper until everything is well-combined and frothy. The egg mixture will bind the casserole together, creating a fluffy texture when baked. Pour this mixture evenly over your layered ingredients in the baking dish, ensuring all the components are soaked.
Step 5: Refrigerate Overnight
Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate the casserole overnight. Allowing it to sit for at least 4 hours lets the bread absorb the savory flavors from the egg mixture, ensuring a moist and fluffy Easy Make-Ahead Breakfast Casserole. If you prefer, you can prepare it early in the morning, letting it chill for several hours.
Step 6: Preheat the Oven
When ready to bake, preheat your oven to 350°F (175°C). This temperature allows for even cooking and helps to achieve a golden-brown finish on top of your casserole. As the oven heats, remove the casserole from the refrigerator to bring it to room temperature for about 15 minutes—this helps it bake more evenly.
Step 7: Bake the Casserole
Uncover the casserole and place it in the preheated oven. Bake for approximately 45 minutes or until the center is set and the top is a delightful golden brown. The casserole should puff up slightly as it bakes, and you’ll know it’s done when a toothpick inserted in the center comes out clean—this means it’s ready to shine at your brunch table!
Step 8: Cool and Serve
Once baked, remove the Easy Make-Ahead Breakfast Casserole from the oven and let it cool for about 10 minutes. This cooling period helps the casserole firm up, making it easier to slice. Use a sharp knife to cut it into squares, then serve warm alongside fresh fruit or a light salad to balance the hearty flavors.
How to Store and Freeze Easy Make-Ahead Breakfast Casserole
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. This keeps the casserole fresh while allowing you to enjoy its hearty flavors.
Freezer: You can freeze the casserole before baking it. Wrap the dish tightly in plastic wrap and aluminum foil, and it will last for up to 2 months. Just thaw in the fridge overnight before baking.
Reheating: To reheat, slice out individual portions and warm them in the microwave for about 1-2 minutes, or bake at 350°F (175°C) until heated through. Enjoy the delicious, comforting flavors of your Easy Make-Ahead Breakfast Casserole!
Serving: If serving after refrigerating, let it come to room temperature for about 15 minutes before reheating for best results.
Expert Tips for Easy Make-Ahead Breakfast Casserole
