  • 1/2 cup (50g) shredded Parmesan, divided
  • 1/4 cup (30g) shredded cheddar cheese, divided
  • 1/4 cup (28g) shredded provolone or gruyere, divided
  • 2 tablespoons (28 g) grass fed butter or ghee (plus more as needed)
  • 1 cup (70g) thinly sliced or chopped mushrooms
  • 2 cups (60g) pre-washed fresh spinach, coarsely chopped
  • 5 large eggs
  • 1/2 cup (120ml) heavy cream
  • 1/4 cup (60g) cream cheese, softened
  • 1 teaspoon sea salt
  • 1 teaspoon granulated garlic
  • 7 slices crispy cooked bacon, crumbled
  • zest of one lemon
  • 1/4 cup (15g) finely chopped fresh Italian parsley
  • 1 cup (240ml) water


  1. In a medium bowl, combine parmesan, cheddar and provolone, set aside

  2. Add the butter to Instant Pot and press "sauté ". Once butter has melted, add the mushrooms and sauté for seven minutes, stirring occasionally until slightly caramelized. Add the spinach and sauté for three minutes, stirring occasionally, just until wilted. Pres the "keep warm/cancel" button.

  3. Grease a 1 1/2 quart baking dish with lid that fits inside the Instant Pot and set aside.

  4. In a large bowl, whisk together eggs, heavy cream and cream cheese until eggs are fully incorporated. Add salt, garlic, bacon, lemon zest, parsley, three quarters of the cheese mixture and the mushroom mixture, gently stirring to combine. Pour the mixture into the prepared baking dish. Place lid on baking dish.

  5. Pour water into the Instant Pot, place Instant Pot Trivet into the Instant Pot. Carefully transfer baking dish to Instant Pot on top of the trivet. Place lid on the Instant Pot, making sure the steam release valve is sealed. Press the 'manual' button and set timer for 25 minutes.

  6. When Instant Pot beeps, press warm/cancel. Allow the Instant Pot to naturally release pressure for ten minutes. Using and oven mitt "quick release" the steam release valve. When the steam stops venting, and silver dial drops, carefully open lid.

  7. Carefully remove dish from the Instant Pot and remove lid from the dish. Next add the remaining reserved cheese mixture to the top of the quiche and either place quiche back into the Instant Pot with the lid on or place under a preheated broiler in the oven for three minutes or until cheese is slightly brown.

  8. Allow quiche to rest for 15 minutes.

  9. Note: if your baking dish does not have a lid, you can cover the top with parchment paper then secure the edges with aluminum foil.
