Ingredients

Scale

Vegetables

  • 2 small leeks, rinsed well, halved and sliced
  • 8 oz mushrooms, cleaned and sliced
  • ½ cup red bell pepper, chopped
  • 2 cloves garlic, chopped
  • 3.5 ounces fresh baby spinach (2 large handfuls)
  • 1 13.75 oz-can artichoke hearts, drained well and chopped
  • ½ cup cherry tomatoes, halved (for topping)

Wet Ingredients

  • 2 tablespoons extra-virgin olive oil
  • 1 ½ 16-oz cartons JUST Egg (24 oz total)
  • 1 cup soy milk (or cashew milk)
  • ½ cup unsweetened vegan yogurt (Greek style, or vegan sour cream)

Cheeses

  • 1 cup shredded vegan Parmesan cheese (divided)
  • ½ cup shredded vegan Cheddar cheese

Spices and Seasonings

  • 1 teaspoon dried herbes de Provence
  • ¾ teaspoon pink Himalayan salt (divided)
  • ¾ teaspoon kala namak (black salt)
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder

Other

  • 1 tablespoon Dijon mustard

Instructions

  1. Preheat and Prepare Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease an 11-inch by 7-inch baking dish to prevent sticking and set aside.
  2. Sauté Leeks: Heat the olive oil in a skillet over medium to medium-low heat. Add the sliced leeks and season with ¼ teaspoon of the salt. Sauté for about 3 minutes, or until the leeks soften and become fragrant.
  3. Cook Garlic and Vegetables: Add the chopped garlic to the skillet and cook for an additional minute. Then stir in the sliced mushrooms, chopped red bell pepper, and the remaining ½ teaspoon of salt. Continue sautéing for several minutes until the vegetables are softened and slightly browned.
  4. Wilt Spinach and Add Artichokes: Add two handfuls of baby spinach to the skillet and stir to combine. Cook until the spinach is mostly wilted, approximately 3 minutes. Remove the skillet from heat, then stir in the chopped artichoke hearts. Set this vegetable mixture aside.
  5. Mix Egg Base: In a large mixing bowl, whisk together the JUST Egg, soy milk, unsweetened vegan Greek-style yogurt, Dijon mustard, ½ cup of vegan Parmesan cheese, vegan Cheddar cheese, kala namak, garlic powder, and onion powder until fully combined.
  6. Assemble in Baking Dish: Pour the cooked spinach and vegetable mixture into the prepared baking dish. Then pour the JUST Egg mixture over the vegetables, gently folding them together with a spatula to evenly distribute.
  7. Add Toppings: Sprinkle the remaining ½ cup of vegan Parmesan cheese evenly over the top of the frittata mixture. Arrange the halved cherry tomatoes on top for a fresh, colorful garnish.
  8. Bake the Frittata: Place the baking dish in the preheated oven and bake for 65 to 70 minutes. Bake until the edges are golden brown and crispy, and the JUST Egg is completely set in the center. If the edges begin to brown too much, cover loosely with aluminum foil to prevent burning.
  9. Cool and Serve: Remove the frittata from the oven and allow it to cool on the counter for about 10 minutes before slicing and serving. This helps it firm up for easier cutting.

Notes

  • You can substitute soy milk with other plant-based milks like cashew or almond milk for a slightly different flavor.
  • Kala namak (black salt) adds an authentic eggy flavor; if unavailable, it can be omitted but will reduce egg flavor notes.
  • If you prefer a crispier top, broil the frittata uncovered for 1-2 minutes at the end of baking but watch carefully to avoid burning.
  • This frittata keeps well in the refrigerator for up to 3 days and can be reheated in the oven or microwave.
  • For a gluten-free version, ensure the vegan cheeses and yogurt used are certified gluten-free.
  • You can add other vegetables such as zucchini or asparagus depending on seasonality and preference.
