  • 4 eggs
  • 1 cup half and half
  • 1/2 -1 tsp Salt
  • 1 teaspoon Ground Black Pepper
  • 1 teaspoon Smoked Paprika
  • 1 teaspoon Herbes de Provence
  • 1 cup shredded parmesan or swiss cheese
  • 1 cup chopped green onions green and white parts
  • 8 oz imitation crab meat about 2 cups OR
  • 8 oz real crab meat, or a mix of crab and chopped raw shrimp


  • In a large bowl, beat together eggs and half-and-half with a whisk. (I don’t know if this will work with non-dairy milk since it needs to set).
  • Add salt, pepper, sweet smoked paprika, Herbes de Provence, and shredded cheese, and stir with a fork to mix.
  • Stir in chopped green onions.
  • Add in EITHER the imitation crab meat OR the real crab meat OR some combination of crab meat and chopped raw shrimp. You only want 2 cups of seafood however you do this
  • Lay out a sheet of aluminum foil that is cut bigger than the pan you intend to use. Place the spring form pan on this sheet and crimp the sheet about the bottom
  • You are doing this as most spring form pans can leak a little with liquids. The aluminum foil reduces the mess a little.
  • Pour in the egg mixture into your spring form pan. Cover loosely with foil or a silicone lid.
  • Into the inner pot of your Instant Pot or pressure cooker, place 2 cups of water. Place a steamer rack in the pot.
  • Place the covered spring form pan on the trivet.
  • Cook at high pressure for 40 minutes. Let the pot sit undisturbed for 10 minutes and then release all remaining pressure.
  • Very carefully take out the hot silicone pan. Using a knife, loosen the edges of the quiche from the pan. Remove the outer ring, and serve your delicious crab quiche either hot or at room temperature.



  • Bake it in the oven at 350F for 35-40 minutes
  • Substitute cheddar or Swiss cheese for the parmesan
  • Add some goat cheese or feta for a tang
  • Add ½ cup chopped cooked bacon Swap red or white onions for the green onions
  • Swap diced broccoli for the green onions
  • Use Italian blend herbs, or Greek herbs for the Herbes De Provence
  • Use heavy whipping cream instead of half and half
  • Sub real crabmeat for the imitation crab
  • Use a mix of crab meat and chopped raw shrimp
