This Easter Breakfast Bake is a tasty mix of eggs, cheese, and veggies all baked together in one dish. It’s perfect for feeding a crowd during celebrations!
What I love most is how easy it is to prep the night before. Just pop it in the oven in the morning, and you’ll be ready to enjoy a delicious breakfast without the stress!
Key Ingredients & Substitutions
Day-old Bread: Use French bread or sourdough for the best texture. If you don’t have these, any sturdy bread like challah or whole grain will work. Just make sure it’s slightly stale so it absorbs the egg mixture well.
Breakfast Sausage: Cooked breakfast sausage gives flavor, but feel free to swap it with turkey sausage or a plant-based sausage for a lighter option. Crumbled bacon or diced ham are also tasty alternatives!
Mushrooms: I love using button or cremini mushrooms for their mild flavor. If you’re not a fan, try spinach or diced zucchini for a different veggie twist.
Pepper and Onion: Red bell peppers add sweetness and color, but green bell peppers or even some spicy jalapeños can add a kick. Yellow or white onions work beautifully too if you prefer a milder onion taste.
Cheese: Cheddar is classic, but mozzarella makes it extra gooey. You could also use pepper jack for some spice or a mix of your favorites!
How Do I Make Sure My Casserole Sets Perfectly?
With a dish like this, the key is in the egg mixture. Ensure that you whisk the eggs thoroughly with the milk to create a smooth custard. This helps the casserole set evenly.
- Do not rush the sauté process; ensure the vegetables are softened well before adding them to the egg mixture. This releases some moisture and improves texture.
- Stir the bread and mix-ins gently to avoid breaking up the bread too much. You want chunky pieces for a lovely texture!
- Watch the baking closely. You want the top to be golden and slightly puffed. If it looks too dark on top before setting, you can cover it with foil.

How to Make the Perfect Easter Breakfast Bake
Ingredients You’ll Need:
For the Bake:
- 8 cups cubed day-old bread (such as French bread or sourdough)
- 1 cup cooked breakfast sausage, crumbled
- 1 cup diced mushrooms
- 1/2 cup diced red bell pepper
- 1/2 cup diced onion
- 8 large eggs
- 2 cups whole milk or half-and-half
- 1 cup shredded cheese (cheddar or mozzarella)
- 2 tbsp butter
- Salt and black pepper to taste
- Fresh parsley, chopped (for garnish)
- Optional: sour cream or cream sauce drizzle
For Topping:
- 4 large eggs (for topping)
How Much Time Will You Need?
This delicious Easter Breakfast Bake will take about 15 minutes to prepare and around 40-45 minutes to bake. Including cooking the eggs for topping, you should plan for about 1 hour total. It’s a great dish to prepare ahead of time and enjoy with family!
Step-by-Step Instructions:
1. Preheat and Prepare Your Dish:
Start by preheating your oven to 350°F (175°C). While that heats up, take a 9×13-inch baking dish and grease it with butter or a non-stick spray. This will prevent the bake from sticking, making it easier to serve later on!
2. Sauté the Veggies:
In a medium skillet over medium heat, melt the 2 tablespoons of butter. Once melted, add the diced onions, mushrooms, and red bell pepper. Sauté for about 5-7 minutes, stirring occasionally, until the veggies are tender and fragrant. When they’re just right, remove the skillet from the heat.
3. Mix the Egg Mixture:
In a large mixing bowl, crack the 8 large eggs and whisk them together with the milk (or half-and-half), adding salt and pepper to taste. Whisk until everything is well combined and fluffy. This is the creamy base of our casserole!
4. Combine All the Ingredients:
Now it’s time to bring everything together. Add the cubed bread, crumbled sausage, sautéed veggies, and shredded cheese into the bowl with the egg mixture. Gently stir everything until it’s well mixed and the bread is coated with the egg mixture.
5. Pour and Bake:
Pour the whole mixture into your greased baking dish. Use a spatula to spread it evenly across the dish. Pop it in the oven and bake uncovered for 40-45 minutes, or until the casserole is set and the top is golden brown. You want a beautiful golden crust!
6. Prepare the Topping Eggs:
While the casserole is baking, you can cook the 4 large eggs sunny side up or over easy in a separate skillet. This will add a lovely touch to each serving when it’s time to serve!
7. Serve and Garnish:
Once the casserole is done baking, carefully remove it from the oven. Place a cooked egg on top of each square or serving of casserole. Finish it off with a sprinkle of fresh chopped parsley and, if you’d like, drizzle over some sour cream or a light cream sauce for extra flavor.
8. Enjoy!
Serve your hearty Easter Breakfast Bake warm and enjoy a delightful meal with family and friends!
Can I Use Fresh Bread Instead of Day-Old?
While day-old bread absorbs the egg mixture better, you can use fresh bread. Just let it sit out for a few hours or lightly toast it to reduce moisture, which helps prevent sogginess in the bake.
How Can I Adjust the Recipe for Dietary Restrictions?
If you need a gluten-free option, use gluten-free bread. For a dairy-free version, substitute the milk with almond or oat milk and switch the cheese for a dairy-free alternative. You can also use a plant-based sausage or omit it entirely!
Can I Make This Dish Ahead of Time?
Yes! You can prepare the entire dish the night before and refrigerate it. Just add a few extra minutes to the baking time since it will be going into the oven cold.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm it in the oven or microwave until heated through. You can also add a splash of milk when reheating to rejuvenate the texture.
