This Easter Breakfast Casserole is a fun and easy way to start your holiday! Packed with eggs, cheese, and your favorite veggies or meats, it’s a true crowd-pleaser.
I love how you can prepare it the night before. Just pop it in the oven while everyone is hunting for eggs, and breakfast is ready to go! 🐣🍽️
Key Ingredients & Substitutions
Breakfast Sausage: I love using pork breakfast sausage for its rich flavor. If you’re looking for a lighter option, turkey or chicken sausage work well too. For a vegetarian alternative, try crumbled tofu or a meatless sausage with lots of flavor.
Eggs: Large eggs are a must for this recipe, but you can substitute them with egg whites if you’re watching your cholesterol. Just remember that whole eggs give a richer taste and fluffier texture!
Cheddar & Mozzarella Cheese: I often use sharp cheddar for a tangy kick alongside mozzarella for its melty goodness. If you prefer a different flavor, pepper jack adds a nice spice, while a dairy-free cheese can be used for vegan options.
Mixed Vegetables: Frozen mixed veggies are super convenient. Fresh vegetables are great too—spinach, bell peppers, or diced zucchini can be used. Don’t hesitate to switch things up based on what you love or have on hand!
Green Onions: They add a fresh crunch! If you don’t have them, chives are a good substitute, or you can skip it altogether if you prefer a milder flavor.
How Can I Ensure My Casserole is Perfectly Cooked?
Cooking this casserole just right is key to its texture. Here’s how to make sure it’s perfectly set and golden:
- Preheat your oven well before baking to ensure even cooking.
- Check doneness after 45 minutes; it should look puffed and the top golden brown.
- Give it a few minutes to cool before cutting; this helps set the casserole for neater squares.
- Use a toothpick—if it comes out clean, your casserole is ready!

- 8 large eggs
- 1 cup milk
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 cup frozen mixed vegetables (corn, peas, carrots), thawed

How Much Time Will You Need?
This Easter Breakfast Casserole takes about 15 minutes to prepare and around 45-50 minutes to bake. Altogether, you’re looking at about 1 hour of total time before it’s ready to serve, making it a quick and easy option for your Easter morning gathering!
Step-by-Step Instructions:
1. Prepping the Oven and Baking Dish:
First, let’s get your oven ready! Preheat it to 350°F (175°C). While the oven heats up, grease a 9×13-inch baking dish with some cooking spray or butter. This will prevent sticking and make cleanup a breeze!
2. Cooking the Sausage:
Next, grab a skillet and cook the breakfast sausage over medium heat. Keep stirring until it’s nice and browned and crumbly. Once it’s done, drain off any excess fat and set it aside. The sausage adds great flavor to your casserole!
3. Mixing the Egg Base:
In a large bowl, whisk together the eggs and milk until they’re combined. Add in the salt, pepper, and the optional garlic powder if you want an extra kick. Stir until everything looks smooth and mixed.
4. Combining All the Good Stuff:
Now it’s time for the fun part! Stir the cooked sausage, thawed mixed vegetables, chopped green onions, and both cheeses into the egg mixture. Make sure everything is evenly distributed—this will ensure every bite is delicious!
5. Assembling the Casserole:
Pour your colorful mixture into the greased baking dish and spread it out evenly. This helps it cook uniformly, so none of it is left behind on the edges!
6. Baking Time:
Put the baking dish in the oven and bake it uncovered for about 45-50 minutes. You’ll know it’s ready when the casserole is set in the middle and the top is golden brown. It should look so appetizing when you take it out!
7. Serving It Up:
After taking it out of the oven, let the casserole cool for a few minutes. This makes it easier to cut. Once it’s slightly cooled, slice it into squares and serve it hot. Enjoy this hearty dish with your friends and family on Easter morning!
This casserole is not only filling but also filled with color and flavor, perfect for a festive breakfast gathering. Enjoy the yummy flavors!
Can I Use Different Types of Meat in This Casserole?
Absolutely! While breakfast sausage is the most common choice, you can use crumbled turkey sausage, ham, or even cooked bacon. Just make sure it’s fully cooked before adding it to the mixture.
What If I Don’t Have Frozen Mixed Vegetables?
No problem at all! You can use fresh vegetables such as spinach, bell peppers, or zucchini, just make sure to chop them into small pieces. If using fresh, sauté them slightly beforehand to soften them up a bit.
Can I Prepare This Casserole the Night Before?
Yes, you can! Simply prepare the casserole up to the baking step, cover it tightly with plastic wrap, and refrigerate it overnight. In the morning, just pop it in the oven; you may need to add a few extra minutes to the baking time since it will be cold.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm them in the microwave or oven until heated through. You can also enjoy it cold for a quick breakfast option!
