This Egg Bake Casserole is a warm and hearty dish packed with eggs, cheese, and those yummy veggies you love. It’s perfect for breakfast or brunch!
Making it is a breeze—just mix, pour, and bake. I usually whip this up when friends come over; it’s a crowd-pleaser that always disappears fast! 🍳✨
Key Ingredients & Substitutions
Eggs: Fresh large eggs are essential for the base of this casserole. If you want a lighter meal, egg whites can be used instead. Just remember it may change the texture slightly.
Bread: Cubed French bread gives a nice texture. If you don’t have that, any sturdy bread like sourdough or whole wheat works great too. Gluten-free bread can be a substitute for those with dietary restrictions.
Cheese: Cheddar cheese provides a wonderful flavor, but mozzarella is a milder alternative. If you’re dairy-free, consider using vegan cheese or omitting it entirely.
Mushrooms: I love using button or cremini mushrooms for their flavor. Spinach or bell peppers are also tasty substitutes, adding their own unique twist.
Broccoli: Fresh broccoli is my go-to, but frozen broccoli works just fine. Just be sure to thaw and drain any excess water. Other vegetables like zucchini or kale would be delicious too!
How Do I Ensure My Casserole Is Perfectly Set?
A key step in achieving the perfect egg bake is ensuring the eggs are set without being overcooked. Here’s how:
- Keep an eye on baking time. Start checking at 40 minutes—look for a firm center.
- Let it rest after baking. This helps the casserole firm up and makes it easier to cut.
- Use a toothpick. Insert it into the center; if it comes out clean, your casserole is done!
These tips will help you serve a delightful and satisfying Egg Bake Casserole for any occasion! Enjoy!

How to Make Egg Bake Casserole
Ingredients You’ll Need:
For the Casserole:
- 8 large eggs
- 2 cups whole milk
- 6 cups cubed bread (such as French bread or a sturdy white bread)
- 1 cup shredded cheddar cheese
- 1 cup sliced mushrooms
- 1 cup broccoli florets, small pieces
- 1 medium tomato, diced
- 1/4 cup chopped fresh parsley
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons butter or oil (for sautéing mushrooms)
How Much Time Will You Need?
This Egg Bake Casserole takes about 15 minutes of preparation time along with 40-45 minutes of baking time. So, you can have a delicious breakfast ready to serve in about an hour!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures it’s hot enough to cook the casserole evenly. While the oven heats up, grease a 9×9-inch casserole dish to prevent sticking.
2. Sauté the Mushrooms:
In a skillet, add butter or oil and heat it over medium heat. Once the oil is warm, add the sliced mushrooms. Sauté them for about 5 minutes until they become tender. This brings out their flavor! Once done, set them aside.
3. Whisk the Egg Mixture:
In a large mixing bowl, crack in the eggs and pour in the milk. Add the salt and black pepper. Whisk everything together until it’s well combined and fluffy. This will be the base of your casserole.
4. Combine Ingredients:
Add the cubed bread, sautéed mushrooms, chopped broccoli, diced tomato, shredded cheddar cheese, and half of the chopped parsley into the egg mixture. Stir everything together gently until it’s well mixed.
5. Pour into the Dish:
Carefully pour the mixture into your prepared casserole dish, spreading it out evenly so every bite has all those delicious flavors.
6. Bake to Perfection:
Place the casserole in the preheated oven and bake for 40-45 minutes. Keep an eye on it! You’ll know it’s done when the eggs are fully set and the top is golden brown.
7. Cool and Garnish:
When it’s done baking, take the casserole out of the oven and let it cool for about 5 minutes. This will help it firm up a bit, making it easier to serve. Before you dig in, sprinkle the remaining parsley on top for a fresh touch!
8. Serve and Enjoy:
Your Egg Bake Casserole is now ready to be enjoyed! Serve hot and watch it disappear at your next breakfast or brunch gathering!
Enjoy this savory and comforting dish that’s perfect for feeding a crowd or just enjoying with your family!
Can I Use Different Vegetables in This Casserole?
Absolutely! Feel free to swap the broccoli and tomatoes with your favorite vegetables like bell peppers, spinach, or zucchini. Just make sure they’re chopped into small pieces for even cooking.
Can I Prepare This Casserole Ahead of Time?
Yes, you can! To prepare it ahead, assemble everything the night before, cover it, and refrigerate. In the morning, just bake it straight from the fridge, but allow a few extra minutes for cooking.
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 up the whole casserole in the oven at 350°F (175°C) until heated through.
Can I Freeze This Casserole?
Yes, this casserole freezes well! Just let it cool completely after baking, then wrap tightly with plastic wrap and aluminum foil. It can be frozen for up to 2 months. Thaw overnight in the fridge before reheating.
