Ingredients you'll need
- eggs- use large eggs for this recipe
- milk- optional; swap for unsweetened non-dairy milk if you'd like
- bacon- adds a nice, salty flavor to the casserole. You can swap for cubed ham, cooked and crumbled sausage, or leave it out.
- vegetables- frozen spinach (do not thaw) and bell peppers add color and nutrition, but you can get creative! More details are below.
- cheese- we fold some of the cheese into the casserole for added flavor, and sprinkle some on the top of the casserole.
Step by step directions
1. Mix together ingredients- in a bowl or large measuring cup, beat the eggs. Mix in the milk, bell peppers, frozen spinach, salt, bacon and ⅔ of the shredded cheese.
2. Prepare the Instant Pot- place 1 cup (for the 6 quart) or 1.5 cups (for the 8 quart) in the stainless steel insert of the Instant Pot. Place the trivet on top and a well-greased 7 inch cake pan on the trivet.
3. Add egg mixture- carefully pour the egg mixture into the cake pan. Sprinkle the top with reserved shredded cheese.
4. Cover- carefully work a piece of aluminum foil over the pan, working the edges around the cake pan. It does not have to be super tight.
5. Cook- Place the lid on the Instant Pot, set the steam release handle to 'sealing', and pressure cook on high pressure for 30 minutes. Once the Instant Pot beeps, perform a quick pressure release by carefully transferring the steam release handle to the 'venting' position.
Recipe FAQ
For this recipe, I recommend using a A 7 inch cake pan. Springform pans did work as well, but leaked slightly while cooking.
This recipe has been tested in a 6 quart Instant Pot as well as an 8 quart Instant Pot. It will not fit into an Instant Pot mini
We are using a quick pressure release for this recipe to ensure that our breakfast casserole does not overcook (no one likes rubbery eggs!). To do a quick pressure release, carefully transition the steam release handle from the ‘sealing’ position to the ‘venting’ position.
Be extremely cautious when doing a quick release handle: never place your face, hand, or any other object over the valve when releasing steam.
For more information about quick versus natural pressure release, check out Instant Pot 101.
In order to get the casserole out of the pan, it's important to grease the pan well before cooking. You can use spray oil or butter, and a paper towel to work it into the corners of the pan.
Another helpful tip is to allow the casserole to rest for at least 10 minutes. As the casserole cools, it shrinks slightly, making it much easier to get out.
Variations
We love this breakfast casserole as written, but you can have fun getting creative with them! Here are some add in ideas:
- cooked + crumbled sausage
- cubed ham

- frozen broccoli rice

- roasted red pepper (finely chopped)
- mushrooms (sautéed)

When adding your own personal touch to this casserole dish, don’t go too crazy; you don’t want to overfill the cake pan as it may not cook through fully. Stick to 2 cups of add ins.

Storage + Reheating
This casserole stores and reheats surprisingly well for eggs! Here’s how to do it:
- fridge– cool completely, then store individual slices in an air tight container, or cover the whole cake dish and store. Refrigerate for up to 4 days.
- freezer– cool completely, then wrap individual slices or the whole casserole tightly in plastic wrap. Store in a freezer bag, reusable silicone bag, or meal prep container in the freezer for up to 3 months.
- thaw– thaw overnight in the fridge.
- reheat– heat in the microwave until steaming hot. You may wish to heat on a paper towel to absorb extra moiture.
