Add the bell peppers and potatoes and season to taste with salt and pepper. Cook, stirring constantly, for 4-5 minutes. Transfer the vegetables to the prepared casserole dish.

Tips To Make The Best Potato Egg Casserole Recipe

• Cut the potatoes into small cubes to help them cook all the way through.
• Use fresh potatoes for your breakfast potatoes instead of frozen ones. The starch in the fresh potatoes will help thicken up the casserole filling.
• You'll know the casserole is done cooking when the egg has set and the cheese is melted and golden on top.
• Let the casserole cool for a few minutes before serving so the cheese can set.

Recipe Variations

As I mentioned earlier, this potato breakfast casserole is super versatile and can be changed up every time you make it. Here are some ideas to get you started...

Add meat: You can add breakfast meat to add some protein to this breakfast casserole. Cooked bacon, turkey bacon, breakfast sausage, italian sausage, and ham are all great options.

Add veggies: Any veggies, like broccoli, green onions, chopped spinach, zucchini, or red bell peppers, are great healthy additions to the casserole.

Use different cheese: Add some other cheeses like Swiss cheese, mozzarella cheese, pepper jack cheese, or any other shredded cheese along with the shredded cheddar cheese.

Use different potatoes: Feel free to use frozen hash browns or even tater tots instead of diced potatoes. 

How To Store Breakfast Potato Casserole

In the fridge: Store any leftover breakfast potato casserole in an airtight container or cover the casserole dish with a lid. It will last in the fridge for 3-4 days. If you make it ahead of time, the uncooked casserole will last covered in the fridge for a day. 

In the freezer: Transfer the casserole to a freezer-safe bag or airtight container, and you can freeze it for up to 2 months. 

Reheating: For a single serving of this egg and potato breakfast casserole, you can microwave it for 30 seconds or until thoroughly heated. You can reheat multiple servings in the oven at 350°F for 10-15 minutes or until warmed through. If you're reheating the casserole directly from the freezer, bake it in the oven at 350°F covered for 1 hour, then uncover and cook it for another 30 minutes or until it's warm and the cheese remelts.
