Ham, Egg, and Cheese Casserole in the Instant Pot.

Hey friends! Today I’m sharing a recipe from my second book, Come Home To Supper (page 155). This ham, cheese, and egg casserole is a favorite for a low-carb and protein-rich supper, weekend brunch, or breakfast for a group over the holidays or any celebration. Christmas and Thanksgiving morning will be here before you know it! 

It’s overflowing with all the good stuff you need to make the perfect brunch. This includes ham (the perfect recipe to make with ham leftovers), cheddar cheese, golden hashbrowns, and eggs, of course. Fortunately, it’s also one of the easiest casseroles to make – just what you want after a big celebration. Simply combine the ingredients and cook in the kitchen appliance of your choice.

I’m using my Instant Pot to make my ham, cheese, and egg casserole. However, it is a slow cooker or oven recipe as well. Instructions for the different cooking methods are in the printable recipe at the bottom of this post. I’ve had tons of people ask me for Instant Pot recipes since I first mentioned having one, so here we go!

Ingredients for Ham, Egg, and Cheese Casserole.

Recipe Ingredients

  • Onion
  • Shredded cheddar cheese
  • Frozen cubed hash browns
  • Diced ham or meat of your choice
  • Milk
  • Eggs
  • Salt and pepper

How to Make Ham, Egg, and Cheese Casserole

Casserole ingredients.

Layer 1/3 of frozen hash browns, 1/3 of onions, 1/3 of ham, and 1/3 of shredded cheese in your insert. Repeat this two more times until it is all used up.

Beat eggs, milk, salt, and pepper together and pour over layers.

Instant Pot Instructions

The instant pot has several settings. Personally, I’m just tossing all this in and using the slow cooker setting.

I press “slow cooker” and then press “adjust” until it goes to the “less” light on the display screen.

I now have it slow cooking on low. From there I use the plus or minus sign to move the time up to 7 hours. If you want to cook this on high, just press “slow cooker” and it is automatically on high. Then adjust your time to anywhere between 3 to 4 hours.

You could probably adapt this recipe for a pressure cooker, but I usually reserve pressure cooking in my instant pot for roasts, chickens, stews, dried beans, boiled eggs, and potatoes.

Dig in!


  • Store breakfast casserole leftovers in an airtight container in the fridge for up to 4 days.
  • To freeze this ham, egg, and cheese casserole, wrap it up tight and freeze it unbaked for up to 3 months (learn how to freeze a casserole the right way!). To bake, completely thaw in the refrigerator for 24 to 36 hours. Remove from the refrigerator 30 minutes before baking and then follow the baking instructions as shown above.

Recipe Notes

  • You can chop the onions yourself and shred the cheese if you like but I just love buying these frozen chopped onions for a great shortcut on the days when I just want to make my life a tiny bit easier.
  • This breakfast casserole recipe is wonderful with crumbled turkey breakfast sausage. I recommend the Jenn-O brand because that is our favorite. Another option is bacon, of course.
  • See the Instant Pot I have by clicking here.
  • Want to add more flavor? Opt for a teaspoon of Dijon mustard added to the egg mixture or a teaspoon of Italian seasoning. You could also add some fresh herbs, like chopped fresh parsley, chives, thyme, or rosemary.
  • If you’d like to add vegetables, opt for thinly diced bell pepper, zucchini, or mushrooms. Another option is spinach, which pairs perfectly with the casserole.
  • You can use any cheese in this recipe or a combination. Other options include Swiss, Colby, Monterey Jack, Pepper Jack, and Gouda.
  • If you decide to oven bake your casserole, you can also add layers of cubed bread (I recommend between 4 to 6 slices of bread cut into pieces). They just won’t crisp up as well in the Instant Pot.
  • Serve your ham, egg, and cheese breakfast casserole with salsa, hot sauce, or sour cream and chives.

  1. If I’m using a 3 quart instant pot how do I adjust the slow cooker time? And do I cut the ingredients in half?
