Ingredients for Overnight Breakfast Casserole

Base Ingredients

• 3 green onions (thinly sliced)
• 12 slices thick sandwich bread (cubed, about 14 cups)

Custard Mixture

• 6 large eggs
• 3 cups milk
• ½ teaspoon dry mustard powder
• ½ teaspoon each salt & black pepper

Flavor Additions

• ½ red bell pepper (finely diced)
• 12 slices bacon (cooked and crumbled, or 1 cup diced ham)
• 4 cups shredded cheddar cheese

How to Make Overnight Breakfast Casserole Step-by-Step

Step 1: Prepare the Bread

Cube the bread into bite-sized pieces and let them sit out overnight to dry. If short on time, place the cubed bread in the oven at 300°F (150°C) for about 10 minutes. Avoid browning or toasting.

Step 2: Mix the Custard

In a large mixing bowl, whisk together the 6 large eggs, 3 cups milk, ½ teaspoon dry mustard powder, ½ teaspoon salt, and ½ teaspoon black pepper. Ensure all ingredients are well combined.

Step 3: Assemble the Casserole

Grease a 9×13-inch baking dish. Layer half of the cubed bread in the prepared dish. Top this layer with half of the crumbled bacon, sliced green onions, diced red bell pepper, and shredded cheddar cheese. Repeat the layering with the remaining ingredients.

Step 4: Add the Egg Mixture

Pour the egg mixture evenly over the assembled layers, ensuring all bread cubes are soaked. Cover the dish tightly with plastic wrap and refrigerate for at least 3 hours or ideally overnight.

Step 5: Bake

Remove the casserole from the refrigerator and allow it to sit at room temperature while you preheat the oven to 350°F (175°C). Cover the dish with aluminum foil and bake for 45 to 55 minutes. A knife inserted into the center should come out clean. If baking multiple pans, increase the cooking time to 60-80 minutes.

Step 6: Serve

Once baked, let the casserole cool for a few minutes before serving. Enjoy the rich flavors and comforting texture of your Overnight Breakfast Casserole.

This recipe is sure to become a favorite in your household, providing a delicious and convenient way to enjoy breakfast any day of the week.

Pro Tips for the Best Overnight Breakfast Casserole

To achieve the perfect Overnight Breakfast Casserole, consider these essential tips:

• Use Stale Bread: Day-old bread works best as it absorbs the custard mixture without becoming soggy.

• Let it Rest: Allow the casserole to sit for at least three hours (or overnight) to let the flavors meld together fully.

• Check for Doneness: Ensure the casserole is fully cooked by inserting a knife in the center; it should come out clean.

• Cool Before Serving: Let the casserole cool for a few minutes after baking to make slicing and serving easier.

2. Coffee or Tea: A hot cup of coffee or tea rounds out the breakfast experience and provides a comforting beverage option.

3. Hash Browns: These crispy potatoes add a satisfying crunch and are a classic breakfast favorite that pairs well with egg dishes.

4. Pancakes or Waffles: For a more indulgent breakfast, serve with fluffy pancakes or waffles topped with maple syrup.

5. Smoothies: A refreshing smoothie made with fruits and yogurt offers a healthy balance to the hearty casserole.

6. Mimosas: For a festive touch, serve mimosas made with fresh orange juice and sparkling wine to elevate your breakfast gathering.
