Key Ingredients & Substitutions
Eggs: The main base for the casserole, large eggs give it structure. If you need a dairy-free option, you can use a mixture of silken tofu or a dairy-free egg substitute in a similar ratio.
Milk: Whole milk gets a rich taste, but you can swap it for skim milk or a plant-based milk like almond or oat. Just keep in mind it may change the flavor slightly.
Bread: I recommend using day-old bread as it absorbs the egg mixture better. If gluten-free is necessary, try gluten-free bread; it works well in this casserole!
Cheese: Cheddar is a classic choice. For variation, try mozzarella, pepper jack, or feta. If avoiding dairy, use a dairy-free cheese or leave it out entirely.
Veggies: Broccoli and mushrooms add nutrients and flavor. Feel free to mix it up with spinach, bell peppers, or zucchini, based on your preference or what’s in season.
Sausage or Bacon: This is optional but really adds flavor. For a vegetarian option, you can use plant-based sausage or simply load up on more veggies.
How Can You Achieve a Fluffy Egg Casserole?
The secret to a fluffy egg casserole lies in the mixing and baking process. When preparing the egg mixture, whisking well aerates the eggs, resulting in a lighter texture. Don’t skip this step!
- Whisk eggs, milk, and seasonings until well combined and frothy.
- Let the mixture sit for about 10 minutes before pouring it into the baking dish. This gives the bread time to soak and absorb the flavors.
- Baking uncovered helps create that golden top while maintaining a tender inside. Keep an eye on it—every oven is different!
Egg Bake Casserole
Ingredients You’ll Need:
- 8 large eggs
- 2 cups milk
- 4 cups cubed bread (day-old or slightly toasted works best)
- 1 cup shredded cheddar cheese (or a cheese blend)
- 1 cup broccoli florets, chopped
- 1 cup sliced mushrooms
- 1/2 cup cooked sausage or bacon bits (optional)
- 1/4 cup chopped green onions or chives
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1 tablespoon fresh parsley, chopped (for garnish)
- Butter or nonstick spray for greasing the pan
How Much Time Will You Need?
This delicious casserole takes about 15 minutes of prep time and then 40-45 minutes of baking. In total, you’ll need around 1 hour, but make sure to let it cool for a few minutes before serving!
Step-by-Step Instructions:
1. Prepare the Oven and Baking Dish:
Start by preheating your oven to 350°F (175°C). Greasing your 9×13-inch baking dish with butter or a nonstick spray will help prevent the casserole from sticking.
2. Mix the Eggs:
In a large mixing bowl, whisk together the eggs and milk with salt, pepper, and garlic powder. Make sure everything is well combined for a delicious and fluffy texture.
3. Combine the Ingredients:
Add the cubed bread, chopped broccoli, sliced mushrooms, cooked sausage or bacon bits (if you’re using them), shredded cheese, and chopped green onions to the egg mixture. Stir gently until everything is evenly mixed.
4. Pour and Spread:
Carefully pour the mixture into the greased baking dish. Use a spatula to spread it out evenly so it cooks uniformly.
5. Bake the Casserole:
Place the dish in the oven and bake uncovered for 40-45 minutes. You will know it’s done when the eggs are fully set and the top is golden brown.
6. Let It Rest:
Once out of the oven, let the casserole sit for about 5-10 minutes. This will help it hold its shape and make it easier to slice.
7. Serve and Enjoy:
Before serving, sprinkle fresh parsley on top for a nice pop of color. Cut into slices and serve warm. Enjoy your hearty Egg Bake Casserole—it’s perfect for brunch, breakfast, or a cozy dinner!
Happy cooking! 🍽️
Can I Use Different Vegetables in This Casserole?
Absolutely! Feel free to substitute with your favorite veggies. Spinach, bell peppers, or zucchini work well too. Just make sure to chop them into small pieces for even cooking!
Can I Prepare This Egg Bake Casserole the Night Before?
Yes! You can assemble the casserole in advance and refrigerate it overnight. Just be sure to cover it tightly. In the morning, let it sit at room temperature for about 20-30 minutes before baking as this helps it cook evenly.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat individual portions in the microwave or warm them in the oven at 350°F (175°C) until heated through.
What’s the Best Way to Serve It?
This casserole is great on its own, but you can also serve it with fresh fruit, a side salad, or even some hot sauce for an extra kick! Enjoy it warm for the best flavor.
