Ingredients

• (Total Time: 38 MINS| Serves: 8)
• 12 large organic eggs
• ½ cup (120 ml) unsweetened almond milk
• Salt and freshly ground black pepper, to taste
• 3 cups (90 g) roughly chopped fresh baby spinach
• 1 cup (180 g) seeded and chopped tomato
• 3 large scallions, sliced
• 4 tomato slices, for topping
• ¼ cup (25 g) shredded Parmesan cheese
• 1 cup (240 ml) water, for the Instant Pot

Instructions

1. Directions
2. Prep Your Dish: Lightly grease a 1½ quart casserole dish that fits inside your Instant Pot and set it aside.
3. Whisk the Eggs: In a large bowl, whisk together the eggs, almond milk, salt, and pepper until they are smooth and well combined.
4. Layer the Veggies: Add the chopped spinach, chopped tomato, and sliced scallions to the bottom of your prepared casserole dish. Give them a gentle stir to mix.
5. Combine and Top: Pour the egg mixture evenly over the vegetables in the dish. Arrange the 4 tomato slices on top and finish with a generous sprinkle of shredded Parmesan cheese.
6. Set Up the Instant Pot: Place the steamer trivet inside the Instant Pot liner and pour in 1 cup of water. Create a foil sling by folding a long piece of aluminum foil into thirds, and place it over the trivet.
7. Cook Under Pressure: Carefully lower the casserole dish onto the foil sling inside the Instant Pot. Secure the lid, turn the pressure valve to the “Sealing” position, and select “Manual” or “Pressure Cook” on High Pressure for 20 minutes.
8. Release and Serve: Once the cooking time is complete, allow the pressure to release naturally for 10 minutes. Afterward, perform a quick release to vent any remaining steam. Carefully remove the lid, lift out the frittata using the foil sling, and serve warm.
