The Instant Pot Frittata gets a little Reuben flare!


  • 1 cup sauerkraut, drained
  • 1 ½ cups frozen diced potatoes, thawed
  • 3 green onions, sliced
  • 1 cup shredded Swiss cheese, divided
  • 1 cup deli pastrami, coarsely chopped (could substitute leftover corned beef)
  • 6 large eggs
  • 2 tablespoons dill pickle relish
  • 1 tablespoon deli brown mustard
  • ½ teaspoon ground cumin
  • 1 teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • For garnish: Chopped fresh chives
  • For serving: Toasted Pumpernickel or Marble Rye Bread

For the Russian Dressing (double if you like a lot of sauce)

  • 1/3 cup light sour cream or yogurt
  • 2 tablespoons mayo
  • 2 tablespoons ketchup
  • 1 tablespoon dill pickle relish
  • 1/21 teaspoon sriracha or other hot sauce
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon dried parsley
  • ¼ teaspoon dry mustard
  • ¼ teaspoon onion powder


  1. Lightly grease a 7 inch springform pan with nonstick cooking spray.
  2. In a medium bowl, combine sauerkraut, diced potatoes, green onions, ¾ cup swiss cheese, and pastrami; toss.
  3. In another bowl, whisk together eggs, relish, mustard, cumin, salt, and pepper.
  4. Pour egg mixture over meat mixture and stir.
  5. Pour into the prepared pan.
  6. Add 1 cup of water to the pressure cooker pot and place a trivet inside.  Carefully set the springform pan on the trivet.
  7. Secure the lid and turn pressure release knob to a sealed position.  Cook at high pressure for 25 minutes.
  8. While the frittata cooks, combine Russian Dressing ingredients and place in the fridge.  This can be made a day or two in advance.
  9. When pressure cooking is complete, use a natural release for 5 minutes and then release any remaining pressure.  
  10. Remove pan from the pressure cooker.  Top with ¼ cup Swiss cheese. Place under the oven broiler to brown the cheese.
  11. Run a knife around the edge of the pan, remove the outer ring.
  12. Garnish with fresh chives.
  13. Serve wedges of the frittata with a large dollop of Russian Dressing and toast.


  • Chopped leftover corned beef can be used instead of deli pastrami
  • Do not buy canned sauerkraut.  Look for bottled or bagged sauerkraut in the refrigerated section for the best flavor
  • If you have leftover baked potatoes, dice them up and use that instead of the diced potatoes from the freezer aisle
