Instant Pot Breakfast Casserole Ingredients
5-6 eggs
¼ cup milk of choice
1 cup bell pepper, diced
¼ cup green onion, chopped
½ tsp salt
¼ tsp pepper
¼ – ½ cup shredded cheese (I used a mix of cheddar & Gouda)
Equipment
1½ cups water
metal trivet
round, oven-safe casserole dish
Choosing your Instant Pot Egg Casserole Dish
When cooking a casserole in the oven, you’ve got a variety of casserole dish sizes and shapes to choose from. But, when you’re making an instant pot breakfast casserole like this, your options are a bit more limited.
First and foremost, be sure to choose a heat-proof (a.k.a. oven-safe) dish of some sort! You want to make sure that your dish is designed to withstand high temperatures so that it won’t crack during the cooking. Most dishes will tell you on the bottom of the dish or on the packaging whether they’re oven-safe or not.
And of course, the other essential factor is choosing an instant pot egg casserole dish that will actually fit inside of your pressure cooker. For me, my best option was a round, 8-inch corning ware dish and it worked perfectly! Use whatever heat-proof dish fits inside of your machine, or you can even try cooking mini casseroles if those are the dishes that you have.
How to Make a Breakfast Casserole in an Instant Pot
To prepare this instant pot egg casserole recipe, first whisk together your eggs and milk of choice in a large bowl. Non-dairy milk will work fine if that’s what you prefer. Then, add in your favorite chopped veggies and seasonings. I personally went with chopped bell pepper and green onion because that’s what I had on hand, and I kept things simple with salt and pepper.
Next, spray down your chosen casserole dish with cooking spray and pour in your egg mixture. If desired (and highly recommended), sprinkle a generous helping of shredded cheese on top. Again, whatever kind you like—I used cheddar and Gouda!
Finally, pour 1½ cups of water into the instant pot, place the metal trivet inside with your casserole dish on top, and seal up the lid. Using your machine’s manual setting, cook on high pressure for 25-30 minutes. (For my Instant Pot Duo, manual is accessed through the “beans/chili” button. See your machine’s user manual if needed.)
Once cooking finishes, you can quick release the steam before carefully removing the lid. Inside, you’ll find a fluffy, springy, satisfying egg casserole that’s perfect any time of day, warm or cold!
How to Serve & Store
As mentioned, you can serve your instant pot breakfast casserole warm and fresh, or cold as leftovers. If you’ve ever had a cool quiche, you know how delicious a slice of cold casserole can be. A great option to reheat if you want a warm breakfast, or pack cold for an on-the-go lunch!
To store, simply package into an airtight container and keep in the fridge for up to one week. You can store the casserole whole, or slice it into pieces before storing—whatever you prefer.
Or, for longer-term storage or meal prep purposes, you can also freeze slices of this instant pot egg casserole for up to 3 months! Again, just package into a freezer-safe airtight container or freezer bags for storage, and this is best frozen in individual pieces. After freezing, it’s best to thaw overnight and then reheat before enjoying.
Perfect for low carb and keto meal prep, basic make ahead meals, or just simplifying a too-busy kind of morning routine. Seriously, I make this easy casserole nearly every week now, and it is never a mistake!
