  • 6 large eggs
  • ¼ cup dairy-free milk of choice

10-inch skillet

  • 8 large eggs
  • 5 tablespoons dairy-free milk of choice
  • salt and pepper, to taste

12-inch skillet

  • olive oil
  • 4 cups vegetables of choice see notes below for ideas
  • splash of red wine or balsamic vinegar (optional)
  • 10 large eggs
  • ¼ cup + 2 tablespoons dairy-free milk of choice
  • salt and pepper, to taste
  • up to 1 ½ cups add-ins (optional) see notes below for ideas

Instructions

  • Preheat the oven to 350°F/175ºC. 
  • Heat a large oven-safe skillet over medium heat and add a bit of olive oil. Chop all your vegetables into small pieces and roughly chop any leafy greens. 
  • Add the leeks first (or any alliums) and cook for 2-3 minutes or until translucent. Add in the mushrooms (or another vegetable) and cook another 3-4 minutes until they’ve reduced in size and are starting to develop some browning. Season with salt and black pepper. Add in the spinach (or another leafy green), stirring until it's wilted, just a minute or two.
  • Optional: Pour in a splash of balsamic or red wine vinegar and use your spatula to scrape off any brown bits off the bottom of the skillet.
  • In a medium bowl, whisk together the eggs, dairy-free milk, salt, and black pepper until combined.
  • Pour egg mixture over the sauteed vegetables. Add in any additional ingredients such as dairy-free cheese, herbs, or cooked meat. Stir the center a little and let it cook for about 30 seconds before transferring the skillet to your preheated oven.
  • 8-inch skillet: Bake for 15-20 minutes or until the center is set.
    10-inch skillet: Bake for 20-25 minutes or until the center is set.
    12-inch skillet: Bake for 30-35 minutes or until the center is set.
