EASY Potato Egg Casserole

We LOVE breakfast at our house. I’m not joking when I say that we have breakfast for dinner at least ONCE a week. We love pancakes and waffles, cinnamon rolls, smoothies and especially breakfast casseroles, like today’s breakfast casserole with potatoes.

Casseroles are so great, mostly because they’re quick, simple and delicious. Plus, they are easy to change up based on the ingredients you love and crave most.

This particular breakfast casserole has potatoes, eggs, sausage and cheese – some of our favorite breakfast ingredients. The best part of all was that it took just minutes to make!

How to Make It

The ingredients for this egg and potato casserole are simple – eggs, milk, sausage, hash browns, cheese, salt and pepper.

COMBINE. Dividing the cheese and setting a cup aside, mix your eggs, milk, sausage hash browns, salt and pepper. Mix until combined and then pour it into a greased 9×13 pan.

BAKE. Bake this at 350°F for 20-35 minutes. Take the dish out, top with remaining cheese and bake for an additional 5-7 minutes. Let set a few minutes before serving.

Tips + Variations

Make this breakfast potato casserole up to 24 hours in advance. Just cover and keep in fridge until ready to make. You may need to add a few additional minutes to the cook time.

Use shredded hash browns in this breakfast casserole. Cook times should be the same. Just like the cubed hash browns, we recommend making sure these are thawed for best results. If not thawed, it may need an additional few minutes to cook.

There are so many easy ways to change up this recipe. Here are some other variations to try:

  • Mexican – Add chopped bell peppers and use Mexican blend or Monterrey Jack cheese instead
  • Meat lovers – add cooked bacon to this recipe too
  • Low-Fat version – omit the meat and add a cup of chopped spinach

    Delicious! I’ve tried a few variations of this recipe over the years and this is my favorite. I love it for its simplicity and deliciousness. We just ate it for Christmas breakfast and everyone loved it. The amount was perfect for a family of 4 and we even have some leftovers.
    Printing the recipe right now so I won’t forget where I got from 🙂

    1. The recipe was not created as a gluten-free recipe, but you could certainly tweak anything in it that she couldn’t eat to make it work for her. 🙂

    1. Yes, absolutely! Just make sure they are pre-cooked. Leftover baked potatoes are a great option if not using the frozen hash browns.

  2. Only 7oz of cheese? Is the recipe correct on that? It calls for starting with 1 cup (8oz), and reserving the rest for topping.
