Vegan quiche recipe with JUST Egg

Using JUST Egg makes vegan quiche effortless and convincing. This plant-based liquid egg substitute pours, bakes, and tastes very much like traditional eggs, so it’s perfect for quiche. With a ready-made puff pastry crust, colorful vegetables, and shredded vegan cheese, this JUST Egg Quiche is a simple, satisfying centerpiece for brunch.

The filling in this recipe is free from tofu and animal eggs and relies on a short list of pantry-friendly ingredients. Choose a store-bought puff pastry sheet or a vegan pie crust, pile in sautéed or raw vegetables and vegan cheese, then pour the JUST Egg mixture over the top. It bakes in under an hour and pairs well with fruit, scones, or roasted breakfast potatoes.

Ingredients needed (with substitutions)

  • Puff pastry – A frozen sheet of puff pastry is quick and easy. You can also use a vegan pie crust or a homemade crust if you prefer.
  • Red bell pepper – Any color bell pepper works.
  • Mushrooms – Cremini or button mushrooms are ideal, sliced thin.
  • Green vegetables – Baby spinach, broccoli, kale, or asparagus all work well.
  • Shredded vegan cheese – Use your favorite meltable vegan cheese.
  • Cherry tomatoes – Halved and scattered on top.
  • JUST Egg – The liquid plant-based egg substitute used for the filling.
  • All-purpose flour – Helps thicken the JUST Egg mixture; substitute a 1:1 gluten-free flour if needed.
  • Baking powder – Adds a bit of lift for a light texture.
  • Salt – Black salt (kala namak) gives an egg-like sulfur note; regular salt is fine if you don’t have it.
