If you are familiar with this blog, you know I am a huge fan of easy breakfast casseroles. The hash brown crust casserole is one of the most popular recipes on the site. 

I am also a big fan of my Instant Pot! There are so many things you can make with this kitchen appliance. Anything from pasta dishes to BBQ chicken. This Instant Pot breakfast casserole has been one of my favorite things to make so far. It is great if you have company visiting or even if you just need an easy week night meal.

Sausage Breakfast Casserole

How to make Instant Pot Breakfast Casserole

  • Start by putting the Instant Pot on Saute Mode. Add breakfast sausage and cook until brown.
  • Stir in diced peppers and onions and cook another 3-4 minutes.
  • Remove the sausage mixture and wipe out the Instant pot.
  • Pour sausage mixture into a 7-inch round pan or springform pan.
  • Sprinkle cheese on top of sausage and then pour egg/milk mixture on top.
  • Pour 2 cups of water in the Instant Pot. Wrap the pan in foil and place in the instant pot. If using a springform pan, make sure to wrap the foil on the bottom as well, just in case of a small leak.
  • Put lid on and set to manual, 25 minutes. Once finished manually release pressure and let the casserole sit for approximately 10 minutes. Serve warm.

    1. I have never tried that before so I’m not sure. It makes me want to try now though 🙂 I will try this weekend and let you know my results.

    Lol, that was a disaster. My springform pan leaked, but I shoved it in the IP anyway. It wasn’t done when I took it out after 25 mins and released. I finished it in the oven. i’ll try it again with a non-springform pan. I just didn’t have one so I ordered one. I hope it works out better because this looks really yummy.

    I just made this. I was afraid of the springform pan and the liquid. It began leaking on to the counter even before I got it in to the Instant Pot. I persisted and have a lovely casserole and a bit of a mess on the foil and in the pot, but overall it turned out pretty well. I’d like to try it with a solid pan, not a springform, to see if it works without the leaks!

    1. Using the 7-inch dish, I ended up not needing the trivet. I think if you used a smaller dish to cook it in you would need to use the trivet.
