Spinach and Mushroom Egg White Frittata

Ingredients

• egg whites 5 large
• spinach 1 cup
• mushrooms 1/2 cup
• olive oil 1 tbsp
• Parmesan cheese 1 tbsp

Method

1. Prepare the ingredients. Rinse the fresh spinach leaves thoroughly under cold water to remove any dirt. Drain and pat dry with a clean kitchen towel or paper towels. Clean the mushrooms by wiping them with a damp cloth or paper towel, then slice them thinly. Separate 5 large egg whites and measure out 1 tablespoon of grated Parmesan cheese.
   Tip: Drying the spinach well prevents excess water from making the frittata soggy.
2. Sauté the vegetables. Heat 1 tablespoon of olive oil in a non-stick skillet over medium heat. Add the sliced mushrooms and cook for about 5 minutes until they release their moisture and start to brown. Then add the spinach and cook for another 2-3 minutes until wilted and tender. Stir occasionally to combine the flavors evenly.
   Tip: Cook mushrooms until browned to enhance their flavor and texture.
3. Add egg whites. Pour the 5 large egg whites evenly over the cooked vegetables in the skillet. Reduce the heat to low and let it cook gently without stirring. The egg whites will start to set around the edges.
   Tip: Cooking on low heat ensures the egg whites cook evenly without burning.
4. Cook the frittata. Cover the skillet with a lid and cook for about 7-8 minutes until the egg whites are fully set and firm to the touch. Avoid lifting the lid too often to keep the heat consistent. If your skillet is oven-safe, you can alternatively place it under a broiler for 2-3 minutes to set the top.
   Tip: Using a lid traps steam and helps cook the top of the frittata gently.
5. Add Parmesan and serve. Sprinkle 1 tablespoon of grated Parmesan cheese evenly over the cooked frittata. Remove the skillet from heat and let it rest for a minute before slicing and serving. Enjoy your nutritious spinach and mushroom egg white frittata warm.
   Tip: Resting the frittata helps it hold its shape when sliced.

Pro tips

• Use a non-stick skillet to prevent sticking and make flipping easier if needed.
• For extra flavor, add a pinch of salt and pepper to the egg whites before cooking.
