Hearty Egg Casserole with Hashbrowns and Bacon
Bacon, hashbrowns, and cheddar come together in this easy egg casserole—perfect for feeding a crowd or meal-prepping breakfast for the week.
Ingredients
- 12 large eggs
- 1/2 cup milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 3 cups frozen shredded hashbrowns, thawed
- 8 slices bacon, cooked and crumbled
- 1 cup diced ham
- 1 1/2 cups shredded cheddar cheese
- 1/2 cup diced yellow onion
- 1/2 cup diced bell pepper
- Cooking spray or butter, for the baking dish
Instructions
- Preheat the oven to 375°F. Grease a 9x13-inch baking dish with cooking spray or butter.
- Spread the thawed hashbrowns evenly across the bottom of the dish.
- In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until smooth.
- Scatter the bacon, ham, onion, and bell pepper evenly over the hashbrowns.
- Sprinkle 1 cup of the cheddar cheese over the top, then pour the egg mixture evenly over everything.
- Top with the remaining 1/2 cup of cheese.
- Bake for 40 to 45 minutes, until the eggs are set in the center and no longer jiggle, and the top is lightly golden.
- Let the casserole rest for 5 minutes before slicing into 8 squares.
Ingredient Swaps
No ham on hand? Leave it out and add an extra 2 slices of bacon instead, or swap in cooked breakfast sausage for a different flavor. If you want an even lighter option, turkey bacon works fine here too, just crisp it up the same way before adding it in.
Make-Ahead and Storage
You can assemble the whole casserole the night before, cover it, and refrigerate it unbaked. In the morning, let it sit on the counter for 15 minutes while the oven preheats, then bake as directed, adding an extra 5 to 10 minutes if it’s still cold in the center. Once baked, leftovers keep in the fridge for up to 4 days and reheat well in the microwave in individual squares.
FAQ
How much protein does this egg casserole have?
Each of the 8 servings has roughly 30 grams of protein, thanks to the combination of eggs, bacon, ham, and cheese. That’s enough to keep most people full well past mid-morning.
Can I make this egg casserole ahead of time?
Yes. You can assemble it the night before and refrigerate it unbaked, then bake it fresh in the morning. See the Make-Ahead section above for exact timing.
Can I use fresh potatoes instead of frozen hashbrowns?
Yes, shredded fresh potatoes work too; squeeze out as much extra water as you can first so the casserole doesn’t turn watery in the oven.
Why is my egg casserole watery in the middle?
This usually happens when the hashbrowns weren’t fully thawed and drained, or the casserole came out of the oven before the center fully set. Give it the full bake time and check that the center no longer jiggles before pulling it out.
Can I freeze egg casserole?
Yes, baked and cooled squares freeze well for up to 2 months. Thaw them in the fridge overnight and reheat in the microwave or oven until warmed through.
Can I make this without bacon or ham?
Yes, you can leave out the meat entirely for a vegetarian version, or swap in extra vegetables like mushrooms or spinach to keep the protein up with more cheese and eggs.
What can I serve with egg casserole?
A side of fresh fruit or a simple green salad rounds out the meal well. It’s filling enough on its own that you don’t need much else.
