This loaded mashed potato casserole is so good you’ll win everyone over with it…even your mother-in-law! 



Equipment needed: steamer basket and air fryer lid (or oven)

  • 2 ½ pounds mix of red and yellow potatoes, cut into cubes
  • ½ cup butter
  • ¾ cup milk
  • 1 tsp salt
  • ¼ cup ricotta cheese
  • 1 egg yolk
  • 1 cup shredded sharp cheddar
  • 12 slices of bacon, cooked until crispy and cut into 1 inch pieces
  • ¼ cup diced green onions


  1. Pour 1 ½ cups water into bottom of Instant Pot.
  2. Add potatoes to a steamer basket and lower the basket into the Instant Pot.
  3. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 8 minutes. When the time is up move the valve to venting to release pressure, remove the lid. 
  4. Move the steamer basket out of the pot and set aside. Dump the water out of the pot and dry it out.
  5. Turn Instant Pot to sauté setting. Add in the butter and the milk and let the butter melt. Turn off Instant Pot.
  6. Add in the potatoes and mash until creamy. Stir in the salt, ricotta cheese, egg yolk and half of the bacon. Use a spatula to spread the potatoes smooth into an even layer. 
  7. Sprinkle the cheese on top and then the rest of the bacon.
  8. Use the air fryer lid to bake the casserole at 350° F for 7 minutes. If you don’t have an air fryer lid you can add potatoes into a baking dish and bake at 375° F for 20 minutes. 
  9. Sprinkle with green onions and serve.
