Pressure-Cooker Ham & Cheddar Breakfast Casserole

This easy, cheesy casserole has made appearances at holiday breakfasts, potlucks and even my daughter's college apartment to feed her hungry roommates. It's my go-to recipe for action-packed mornings. —Patty Bernhard, Greenville, Ohio

Test Kitchen tips
  • No time for chopping? Use frozen chopped onion to speed things up.
  • Other cooked breakfast meats, such as turkey or pork sausage and bacon crumbles, will work well in this recipe.

      I actually used a 1.75 qt round pyrex baking dish (larger than the recommended size) and I didn't even come close to fitting all of the ham, cheese, onion, or potatoes in it. Also, I tried using Cashew milk instead of dairy milk and that didn't work.

      I wish I would have read the comments before I made this! I cut the recipe in half and it still did not cook all of the way through! We ended up trying to finish it in the microwave. This is definitely a recipe that is not a keeper.
