This quick & easy Instant Pot Breakfast Casserole is made with 5 simple real food ingredients. Perfect for weekends and holidays for the whole family! Try serving alongside Overnight Pumpkin French Toast.
I absolutely LOVE breakfast casseroles.
The Sweet Potato Apple Bake and Overnight Coffee Cake are two of my family’s favorites, and I love that they can be prepped ahead of time and baked quickly in the morning. Breakfast has never been so easy, so fast, and so delicious!
The only thing that can make the breakfast casserole any better, is by making it in the Instant Pot. And wouldn’t you know, you can have that same delicious breakfast on the table in under 30 minutes!
Instant Pot Breakfast Casserole
We’re using FIVE main ingredients for this Instant Pot Breakfast Casserole recipe:
- Shredded potatoes. I used frozen shredded hash browns to save time, but also because there was only one ingredient listed: potatoes! They’re not the cheapest option, so if you’re really pinching pennies, you’re best to shred a couple whole potatoes yourself. You can use the thick hole option on a cheese grater or a food processor to make the job a little quicker.
- Sausage (or ground beef or ground pork). I’m including sausage seasoning in the recipe below, in case you don’t have actual “sausage” in your freezer. I know that I never do! I always buy plain ground beef or plain ground pork and then season it myself!
- Milk. I used almond milk, but you can use cow’s milk or even coconut milk.
- Cheese. I tested this with both cheddar and Colby jack. Both were delicious!
How to Make Instant Pot Hash Brown Casserole
Step One: Sauté the Sausage
- Turn on the pressure cooker to “sauté” and let it heat up.
- Add the ground meat (and seasonings, if used) and break it up using a wooden spoon. Brown the meat until it’s cooked through.
- Remove the sausage from the Instant Pot, add 1 cup of water (add 1 ½ cups of water if you’re using an 8 quart Instant Pot) and scrape up any browned bit on the bottom of the pot so you don’t get a burn notice.
- Add the trivet to the pressure cooker.
Step Two: Make the Egg Mixture
- Measure milk into a large Pyrex measuring bowl.
- Add the eggs, salt and pepper and mix well.
Step Three: Layer the Breakfast Casserole
- Lightly spray an oven-safe round 7” x 4” baking dish with cooking spray.
- Cover the bottom of the pan with thawed hash browns. Press down firmly to create a solid “crust” layer.
- Sprinkle the cooked and crumbled sausage over the hash browns.
- Pour the eggs over the sausage and hash browns.
- Sprinkle the top with shredded cheese.
Step Four: Cook the Breakfast Casserole
- Tightly cover the baking dish with aluminum foil.
- Place the casserole on the trivet, inside the pressure cooker.
- Press the “manual” button and cook on high pressure for 25 minutes.
- Allow the pressure to release naturally.
A Few Tips on Instant Pot Sausage Breakfast Casserole
- This recipe works for both a 6 quart Instant Pot and an 8 quart Instant Pot.
- You WILL need a 7” x 4” metal baking dish, preferably a round one like this one.
- You can substitute tater tots for the shredded potatoes! Create one layer of FROZEN tater tots before adding the sausage layer. Pay attention to the ingredients of tater tots though – many packages have unnecessary ingredients.
- You can use either sausage (ground and pre-seasoned), or ground beef OR ground pork and the optional sausage seasoning in the recipe below. If you’re using sausage, you won’t need the sausage seasoning.
- Turkey or chicken breakfast sausage are also good options! If you start with plain ground turkey or ground chicken, use the sausage seasoning in the recipe below.
- You can make this recipe even faster by batch cooking the sausage ahead of time. Simply cook a full pound (or more) of ground meat and measure out 2 cups when you want to make this recipe!
- I’ve tested this recipe with cheddar cheese and Colby jack cheese. Both were really good! Similarly, Monterey jack and pepper jack would also work well.

** You can substitute ground sausage for any other ground meat. Beef, pork, turkey, chicken, bison and venison would all work great! Be sure to add the “sausage seasoning” to the Instant Pot when you cook the ground meet, otherwise your breakfast casserole will be bland.
