The ultimate Instant Pot Pressure Cooker Breakfast Casserole for an easy dinner or breakfast on the go.



The ingredient amounts listed are for one jar  

  • ½ cup cooked, grated potato (could use thawed store-bought shredded potatoes/hash browns)
  • ½¾  cup extras such as diced raw or cooked veggies (bell peppers, onion, mushrooms, jalapeno, etc), cooked crumbled sausage or bacon, diced ham, etc
  • 2 eggs, beaten with fork
  • 12 tablespoons cheese (pepper jack, cheddar, mozzarella, etc)
  • salt and pepper
  • Optional toppings: salsa, fresh tomato, ketchup, hot sauce, maple syrup, herbs, etc


  1. Spray the inside of a pint Mason jar with nonstick cooking spray.  
  2. Season grated potato with salt and pepper.  Add grated potato to the jar and press flat.  The tighter you pack the potatoes, the better the egg mixture will stay above it.
  3. Add desired veggies and meat and pour beaten egg over top.  Season with salt and pepper.  Top with a sprinkle of cheese.
  4. Repeat for 2 more jars.
  5. Note: 3 mason jars are needed inside the pot for proper cooking.  If only making 1 or 2 breakfast casserole jars, fill empty mason jars with warm water and place inside the pot to make a total of 3 jars
  6. Add 1 cup of water to the pressure cooker pot and place a trivet inside.  Place uncovered jar on the trivet. Secure the lid and turn pressure release knob to a sealed position.  Cook at high pressure for 13 minutes.
  7. When cooking is complete, use a natural release for 5 minutes and then release any remaining pressure.  
  8. To serve, add desired toppings and eat straight from the jar.  Can also run a knife around the casserole and pop the whole thing out onto a plate.  
  9. Caution: jar will be hot!


  • A 6-quart pressure cooker will fit 3 pint jars at a time.  For best results, cook 3 jars at a time. The surrounding heat is needed for even cooking.  If only one or two jars of food are needed, fill extra mason jars with water and place them in to cook alongside the full jars
  • To make smaller half pint jars, decrease add-ins to ¼ cup and decrease cook time to 10 minutes.  Again, you will need surrounding heat for the eggs to cook properly so make at least 4 or up to 6 half pint casseroles or use water filled mason jars instead
