Ingredients

• 1 cup / 150g Diced Tomatoes
• 3 cups / 90g Chopped Fresh Spinach
• ¼ cup / 25g Grated Parmesan Cheese
• ½ cup / 120ml Milk (whole milk recommended)
• 3 Green Onions, chopped
• 12 Large Eggs
• ½ Medium Tomato, sliced for topping
• ½ tsp Garlic Salt
• ¼ tsp Black Pepper
• 1 ½ cups / 355ml Water (for the Instant Pot)

Instructions

1. Directions
2. Pour the 1 ½ cups of water into the inner pot of your Instant Pot and place the trivet inside.
3. Grease a 7-inch round baking dish (or any dish that fits on the trivet) with cooking spray.
4. Layer the chopped spinach, diced tomatoes, and green onions evenly in the bottom of the prepared dish.
5. In a separate medium bowl, whisk together the eggs, milk, garlic salt, and pepper until smooth and fully combined.
6. Carefully pour the egg mixture over the vegetables in the baking dish.
7. Sprinkle the top evenly with grated Parmesan cheese and arrange the tomato slices decoratively.
8. Cover the dish loosely with aluminum foil to prevent condensation from dripping onto the quiche.
9. Carefully lower the baking dish onto the trivet inside the Instant Pot. Secure the lid, set the steam valve to ‘Sealing,’ and cook on HIGH pressure for 20 minutes.
10. When the cooking time is complete, allow for a 10-minute natural pressure release before performing a quick release to vent any remaining steam.
11. Carefully lift the dish out of the Instant Pot. Let it cool for 5-10 minutes before slicing and serving. Enjoy!
