Cook on high pressure for 30 minutes. Allow it to release pressure naturally for 10 minutes, and then release all remaining pressure.
Let it sit for 5-10 minutes. Using a knife, gently loosen the sides of your wondrous creation. Place a plate on top of the pan, and thump out the frittata onto the plate. If you want the pepper and ham side up, you’re done. If you want the cheese side up, flip it on a plate once more.
You can broil for 3-4 minutes to get the cheese to melt or serve as is.
Recipe notes: Subs that will likely work:
Fresh broccoli for frozen
Other veggies instead of broccoli and pepper but do not use tomatoes and possibly mushrooms as they will release too much water.
Dairy-free milks
Individual servings in jars or ramekins, cook 4-5 minutes.
Yes, this reheats very well. No, I would not freeze it.
If you don't eat ham, use some other cooked meat. Raw meats will release too much water. Chicken sausage, roast beef chunks, smoked sausage etc. are all good subs.
