Ingredients for Overnight Egg Casserole
Gathering all the right ingredients is key to making this delicious overnight egg casserole. Here’s what you’ll need:
- 10 large eggs: These will form the base of your casserole. Make sure they’re fresh for the best flavor!
- 2 cups milk: You can use whole milk for creaminess, or a low-fat option if you prefer. This adds moisture and richness.
- 1 cup shredded cheese: I love using a blend of sharp cheddar and mozzarella, but feel free to mix it up with your favorites!
- 1 cup diced bell peppers: Any color works here! They add a nice crunch and sweetness.
- 1 cup diced onions: I usually go for yellow onions for a balanced flavor, but red onions can add a pop of color and a bit of sweetness.
- 1 cup diced cooked ham: This adds a hearty touch, but you could swap it for cooked bacon or sausage, or leave it out for a vegetarian option!
- 1 teaspoon salt: A must for enhancing all those lovely flavors.
- 1/2 teaspoon black pepper: Just the right amount of spice to complement the dish.
- 1 teaspoon garlic powder: This adds a lovely depth of flavor without any chopping!
Having everything prepped and ready will make your cooking experience so much smoother. Now, let’s get cooking!
How to Prepare Overnight Egg Casserole
Preparing this overnight egg casserole is a breeze, and it all comes together in just a few simple steps! Trust me, once you see how easy it is, you’ll want to make it every weekend!
Step 1: Whisk the Base
Start by grabbing a large mixing bowl and crack those 10 large eggs right in! Add in the 2 cups of milk. Now, it’s time to whisk! I like to use a whisk, but a fork works just as well. You want to beat the eggs and milk together until they’re fully combined and nice and frothy. This creates a fluffy base for your casserole.
Step 2: Add Vegetables and Ham
Once your egg mixture looks great, it’s time to add in all the wonderful extras! Sprinkle in the 1 cup of shredded cheese, followed by the diced bell peppers, onions, and ham. Don’t forget to add the salt, black pepper, and garlic powder! Gently mix everything together until all the ingredients are well-coated in that delicious egg mixture. The colors will be beautiful, and the aroma will make your mouth water!
Step 3: Prepare for Refrigeration
Now, grab your greased baking dish. I usually use a 9×13 inch dish, but any similar size will work! Pour that lovely mixture into the dish, spreading it out evenly. Cover it tightly with plastic wrap or a lid and pop it in the refrigerator overnight. This is the magic part—you’ll let all those flavors meld together while you sleep!
Step 4: Baking Instructions
When morning arrives, preheat your oven to 350°F (175°C). Once it’s heated up, uncover your casserole and place it in the oven. Bake for about 45-50 minutes, or until it’s set and slightly golden on top. You’ll know it’s ready when a knife inserted in the center comes out clean! Let it cool for a few minutes before serving, and then enjoy the deliciousness!
Tips for Success with Overnight Egg Casserole
To ensure your overnight egg casserole turns out perfectly every time, here are some of my go-to tips! First, don’t hesitate to customize the vegetables. Spinach, mushrooms, or even zucchini can add a delightful twist. Just make sure to chop them finely so they blend well with the eggs. Next, if you’re worried about the casserole being too soggy, try sautéing the veggies first to remove excess moisture.
Also, this dish is fantastic for meal prep! You can store any leftovers in an airtight container in the fridge for up to 3 days. Just reheat slices in the microwave or oven until warm. And remember, if you want to make it ahead of time for a special breakfast, you can prepare it a full day in advance. Enjoying a cozy breakfast without the morning rush is a dream come true!

FAQ about Overnight Egg Casserole
Can I use different vegetables?
Absolutely! One of the best things about this overnight egg casserole is its versatility. You can swap in any veggies you love or have on hand. Spinach, chopped kale, mushrooms, or even broccoli make fantastic additions! Just remember to chop them into small pieces so they blend nicely into the casserole. If you’re using watery vegetables like zucchini or tomatoes, I recommend sautéing them first to reduce moisture and avoid a soggy casserole.

Can I make this dish vegetarian?
What cheese works best?
For the cheese, I love using a blend of sharp cheddar and mozzarella for that perfect meltiness and flavor. However, feel free to get creative!
