Key Ingredients & Substitutions
Eggs: These are the star ingredient! Fresh eggs give the casserole its fluffy texture. If you’re looking for a lighter option, you can substitute some eggs with egg whites.
Milk: Using whole milk adds creaminess, but you can easily swap it with low-fat or almond milk to accommodate dietary needs. Just remember, non-dairy options might make the casserole less creamy.
Bread: Day-old bread works best as it absorbs the egg mixture without getting too soggy. If you’re gluten-free, any gluten-free bread can substitute. For added flavor, try herbed bread.
Cheese: Cheddar is delicious here, but feel free to mix it up! Monterey Jack or mozzarella can also work well. For a non-dairy option, use a plant-based cheese.
Vegetables: Broccoli, bell peppers, and mushrooms are great choices, but you can include any veggies you like! Spinach, tomatoes, or zucchini could add a tasty twist. Use what you have on hand!
How Do You Ensure the Casserole Sets Perfectly?
Getting the casserole to set just right is crucial. Here’s how to do it:
- Don’t skip the preheating! Make sure the oven is hot enough to cook evenly.
- Mix your ingredients well, ensuring the bread absorbs all the egg mixture. Stir gently to avoid breaking the bread too much.
- Check for doneness! When baking, look for a slight jiggle in the center, but the edges should be firm. If a knife comes out clean, it’s ready!
Let it cool for a few minutes before slicing to help it hold its shape. Enjoy your delicious creation!

Ingredients You’ll Need:
- 8 large eggs
- 1 cup milk
- 4 cups cubed bread (day-old works best)
- 1 cup shredded cheddar cheese
- 1/2 cup chopped broccoli florets
- 1/2 cup chopped red bell pepper

- 3 green onions, chopped
- 1/2 tsp salt

How Much Time Will You Need?
This recipe takes about 15 minutes for preparation and 35-40 minutes for baking, totaling approximately 55-60 minutes. It’s a great make-ahead dish, perfect for family breakfasts or weekend brunches!
Step-by-Step Instructions:
1. Preheat the Oven and Prepare the Dish:
Start by preheating your oven to 350°F (175°C). While it’s heating, take a 9×9-inch baking dish and grease it with butter to prevent sticking.
2. Mix the Egg Base:
In a large bowl, crack the 8 eggs and add 1 cup of milk, 1/2 tsp of salt, and 1/4 tsp of black pepper. Use a whisk to mix everything together until it’s nice and smooth. This is the base of your casserole.
3. Add the Goodies:
Now it’s time to add the fun stuff! Toss in the 4 cups of cubed bread, 1/2 cup chopped broccoli, 1/2 cup chopped red bell pepper, 1/2 cup sliced mushrooms, and half of the chopped green onions. Gently stir everything together so that the bread cubes soak in the egg mixture.
4. Pour into the Baking Dish:
Take the mixture and pour it into your greased baking dish. Spread it out evenly so that it cooks uniformly. You can give it a little shake if you want to level it out.
5. Top with Cheese:
Sprinkle the 1 cup of shredded cheddar cheese evenly over the top of the casserole. This will make a delicious crunchy layer as it bakes!
6. Bake to Perfection:
Place the baking dish in the oven and bake for 35-40 minutes. Keep an eye on it! You’ll know it’s done when the casserole is fully set and the cheese on top is melted and golden. You can test it by inserting a knife in the center—it should come out clean.
7. Cool and Serve:
Once baked, remove the casserole from the oven and let it cool for a few minutes. Before serving, garnish with the remaining chopped green onions for a fresh touch. Slice it up and enjoy a warm, savory slice of this delicious and nutritious egg breakfast casserole!
Perfect for any breakfast occasion, enjoy your delicious creation! 🥚✨
Can I Use Whole Wheat or Gluten-Free Bread?
Absolutely! Whole wheat bread will add a nuttier flavor and additional fiber, while gluten-free bread is a great alternative for those with gluten sensitivities. Just ensure the bread is sturdy enough to hold up when soaked in the egg mixture.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare this casserole the night before! Just assemble it in the baking dish, cover it with plastic wrap, and store it in the refrigerator. In the morning, bake it directly from the fridge, adding a few extra minutes to the cooking time.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3-4 days. To reheat, simply place a slice in the microwave, covered with a damp paper towel, and heat for 30-60 seconds until warmed through.
Can I Add Other Vegetables or Proteins?
Definitely! Feel free to get creative by adding other vegetables like spinach, diced tomatoes, or zucchini. You can also incorporate cooked sausage, bacon, or ham for additional protein and flavor.
