Starting your day with a hearty breakfast casserole is a fantastic way to feed a crowd or prepare breakfast ahead of time. This 9-inch casserole combines eggs, cheese, and your favorite breakfast meats or vegetables for a flavorful, satisfying dish that can be assembled the night before and baked in the morning. Perfect for weekend brunches or holiday mornings, it offers convenience without sacrificing taste.
Ingredients
- 6 large eggs
- 1 cup whole milk (or half-and-half for richer flavor)
- 1 cup shredded cheddar cheese (or a mix of cheeses)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon paprika (optional, for color)
- 1 cup cooked breakfast meats (such as cooked bacon, sausage crumbles, or ham cubes)
- 1 cup diced vegetables (bell peppers, spinach, mushrooms, or onions)
- 2 slices bread, cubed (preferably day-old or toasted)
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9-inch square baking dish or casserole dish with butter or non-stick spray.
- In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and paprika until well combined.
- Layer the cubed bread evenly across the bottom of the prepared dish. If using fresh bread, you can toast it lightly beforehand to prevent sogginess.
- Sprinkle the cooked breakfast meats and diced vegetables evenly over the bread layer.
- Pour the egg mixture over the layered ingredients, ensuring all bread and fillings are soaked. Press down gently if needed to help the mixture settle.
- Sprinkle the shredded cheese evenly over the top.
- Bake uncovered in the preheated oven for 35-40 minutes, or until the casserole is puffed, golden, and a toothpick inserted in the center comes out clean.
- Remove from oven and let it rest for 5 minutes before slicing and serving.
Tips
- For a vegetarian version, omit the meats and add extra vegetables or a can of drained mushrooms for flavor.
- You can prepare this casserole a day in advance. Assemble it, cover tightly with plastic wrap, and refrigerate overnight. Bake directly from the fridge, adding an extra 5-10 minutes to the baking time.
- If you prefer a creamier casserole, substitute half of the milk with heavy cream.
- To prevent sogginess, use slightly stale bread or toast the bread cubes before assembling.
Serving Suggestions
Serve this breakfast casserole with a side of fresh fruit, such as sliced strawberries or melon, and a hot cup of coffee or tea. A dollop of sour cream or salsa on top can add a flavorful kick, or pair it with crispy breakfast potatoes for extra heartiness.
Variations
- Vegetable & Cheese: Add sautéed spinach, mushrooms, or bell peppers for a veggie-packed version.
- Meat Lovers: Use cooked sausage links, ham, or bacon for a protein-rich dish.
- Spicy Kick: Mix in chopped jalapeños or a dash of hot sauce into the egg mixture.
- Gluten-Free: Skip the bread or substitute with gluten-free bread or hash browns for a gluten-free option.
Storage and Reheating
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, slice into portions and microwave on high for 1-2 minutes, or until heated through. For best results, reheat in the oven at 350°F (175°C) for about 10-15 minutes to maintain texture. You can also freeze individual portions for up to 2 months; thaw overnight in the fridge and reheat as described.
Frequently Asked Questions
Can I prepare this casserole the night before?
Absolutely. Assemble the casserole, cover tightly, and refrigerate overnight. In the morning, bake directly from the fridge, adding an extra 5-10 minutes to the baking time to ensure it’s heated through and the cheese is bubbly.
What if I don’t have day-old bread?
If fresh bread is all you have, lightly toast the cubes beforehand to prevent sogginess. Stale or slightly dried bread works best as it absorbs the egg mixture without becoming mushy.
Can I make this casserole gluten-free?
Yes, simply omit the bread or replace it with gluten-free bread or cooked hash browns. The egg, cheese, and fillings remain the same, making it a versatile gluten-free dish.
How do I know when the casserole is done?
The casserole should be puffed and golden on top, with a toothpick inserted into the center coming out clean. It typically takes 35-40 minutes at 375°F, but ovens vary, so start checking around the 35-minute mark.
Can I add different cheeses?
Yes, feel free to experiment with cheeses like Monterey Jack, Swiss, or pepper jack for varied flavors. Just keep the total cheese amount around 1 to 1.5 cups for a balanced taste.
Is this dish suitable for freezing?
Yes, you can freeze individual portions or the whole casserole. Wrap tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge and reheat thoroughly before serving.
