The Necessary Ingredients
To create this Savory Breakfast Casserole, you’ll need the following ingredients:
- 12 large eggs
- 2 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 6 cups bread cubes (preferably stale or day-old)
- 2 cups cooked sausage or bacon, crumbled
- 1 cup shredded cheese (cheddar or your choice)
- 1 cup diced vegetables (like bell peppers, onions, or spinach)
Notes and Substitutions on Ingredients:
- Eggs: They’re the backbone of the casserole, providing structure and richness. You can use egg substitutes if you’re looking for a lower-cholesterol option, just keep in mind that the texture may slightly differ.
- Bread: Stale or day-old bread works best because it absorbs the egg mixture better without becoming too mushy. Fresh bread can still be used, but it might require a shorter soaking time. Consider sourdough or whole grain for an added flavor twist.
- Milk: You can swap out regular milk for nondairy versions like almond or soy milk. However, this might change the creaminess of the casserole.
How to Prepare the Savory Breakfast Casserole Step by Step
Follow these straightforward instructions to craft your casserole:
- Preheat the oven to 350°F (175°C). This ensures that the casserole cooks evenly.
Pro Tip: Make sure your oven is fully preheated before putting the casserole in, as this steps helps achieve that lovely golden-brown crust.
- In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined. This is crucial for a smooth custard mixture that will envelop all other ingredients.
Pro Tip: Whisking incorporates air, resulting in a fluffier final dish. Aim for a light froth on top!
- In a greased 9×13 inch baking dish, layer the bread cubes, cooked meat, vegetables, and cheese. Start with the bread, then add layers of meat, veggies, and cheese in between.
Pro Tip: Evenly distributing the layers helps every bite to be flavorful and ensures the casserole cooks evenly.
- Pour the egg mixture over the top, ensuring everything is evenly covered. Use a spatula to gently push down any floating pieces of bread.
Pro Tip: Give your casserole a gentle shake after pouring to help the egg mixture settle into the layers.
- Cover the dish with plastic wrap and refrigerate for at least 2 hours, or overnight. This soaking time allows the bread to fully absorb the egg mixture.
Pro Tip: Preparing the casserole the night before is ideal for a hassle-free morning!
- Bake in the preheated oven for 45-55 minutes, until the casserole is set and golden brown on top. A knife inserted into the center should come out clean to indicate doneness.
Pro Tip: If the top is browning too quickly, you can cover it loosely with aluminum foil to prevent burning while the inside cooks through.
- Let it cool slightly before slicing and serving. This settling time allows for easier slicing and serving without falling apart.
Pro Tip: A few extra minutes of cooling will improve the texture, making it easier to cut and enjoy.

Serving Suggestions

- Sides: Consider pairing with a light fruit salad or a side of yogurt to balance the richness of the casserole.

Serving Tips:

- Portioning: Use a sharp knife to slice the casserole into neat squares; this makes for effortless serving.
Storage and Reheating Tips
To ensure your casserole remains fresh and tasty:
Refrigerated:
- Store in an airtight container for up to 3-4 days. Reheat portions in the microwave or warmed in the oven until heated through.
Freezed:
- If you wish to freeze, cut into individual portions and wrap tightly in plastic wrap. Then place in a freezer-safe bag or container for up to 3 months.
Reheating:
- To reheat, thaw overnight in the fridge, then bake at 350°F (175°C) for 20-25 minutes, or until warmed through. Microwaving individual portions is also a quick option.
Guaranteed Success Tips
- Don’t overmix the egg mixture: Just whisk until combined to prevent the casserole from becoming dense.
- Use stale bread: This will help the bread hold its shape and soak up the egg mixture without becoming mushy.
- Allow for soaking time: Don’t skip the resting period, as it dramatically improves the casserole’s texture and flavor.
- Check for doneness: Different ovens may result in different cooking times, so keep an eye on it and use the knife test!
Recipe Variations
- For a Spicy Version: Add 1 teaspoon of chili powder and diced jalapeños for a kick!
- For a Vegetarian Option: Omit the meat and double up on vegetables—zucchini, mushrooms, and tomatoes work wonderfully.
- For a Mediterranean Twist: Use feta cheese, spinach, and sun-dried tomatoes for a fresh flavor change.
