Step‑by‑Step Instructions for Delicious Vegan JUST Egg Frittata with Mushrooms
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). While it’s heating, grease an 11 x 7 or 9 x 13-inch baking dish with extra-virgin olive oil. This step is essential to prevent sticking and helps give the frittata a lovely golden crust when baking.
Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced leeks with a pinch of pink Himalayan salt, and sauté for about 3 minutes until they become soft and translucent. The leeks will impart a lovely flavor base for your Vegan JUST Egg Frittata.
Step 3: Add Garlic and Peppers
Stir in the minced garlic and cook for an additional minute, allowing the garlic to become fragrant. Next, add the chopped mushrooms and diced bell pepper to the skillet. Cook for about 4-5 minutes until the mushrooms are tender and the bell pepper is slightly softened, creating a beautiful medley of colors.
Step 4: Incorporate Spinach and Artichokes
Add the fresh baby spinach to the skillet, stirring gently until it wilts—this should take around 2-3 minutes. Once wilted, fold in the artichoke hearts, then remove the skillet from heat. Set the mixture aside as it creates a savory layer in your frittata.
Step 5: Mix the Egg Base
In a large mixing bowl, whisk together the JUST Egg, soy or cashew milk, unsweetened vegan yogurt, Dijon mustard, and the seasoning mix of Herbes de Provence, kala namak, garlic powder, and onion powder. Ensure everything is blended thoroughly for a smooth consistency that will envelop the veggies beautifully in your Egg Frittata Recipe.
Step 6: Combine and Transfer
Gently fold the sautéed vegetable mixture into the prepared egg mixture until everything is well incorporated. Transfer this vibrant mixture into your greased baking dish. Spread it evenly to ensure every slice of frittata has a burst of flavor from the mushrooms and other veggies.
Step 7: Add Toppings
Sprinkle the top of the mixture with vegan parmesan cheese and halved cherry tomatoes to enhance flavor and visual appeal. This final touch adds a delightful texture and freshness to your Vegan JUST Egg Frittata, making it irresistibly inviting.
Step 8: Bake to Perfection
Place the baking dish in your preheated oven and bake for 65-70 minutes. Keep an eye on the frittata; it should turn golden brown and set in the center. If the edges start browning too much, cover them with foil for the last 15 minutes to prevent over-baking.
Step 9: Cool and Serve
Once baked, remove the frittata from the oven and allow it to cool for about 10 minutes. This cooling time helps the frittata to set further, making slicing easier and neater. Afterward, cut it into squares and serve warm, perhaps alongside a crusty bread or fresh salad for a complete meal.

How to Store and Freeze Vegan Egg Frittata

- Freezer: Freeze individual slices wrapped tightly in plastic wrap and then in a freezer bag to prevent freezer burn. It can last up to 2 months for quick meals on the go.
