A flexible, quick, and veggie-packed frittata perfect for using leftover vegetables and creating a nourishing meal in under 30 minutes.

Ingredients

Scale
  • 6 large eggs (room temperature)
  • 1/4 cup (60 ml) milk (whole or 2%, dairy-free milk works too)
  • About 2 cups leftover veggies, chopped (e.g., roasted potatoes, sautéed spinach, bell peppers, mushrooms, zucchini)
  • 1 small onion, finely chopped
  • 1 clove garlic, minced (optional)
  • 2 tablespoons olive oil or butter
  • 1/2 cup shredded cheese (cheddar, mozzarella, or feta)
  • Salt and pepper to taste
  • A handful fresh herbs, chopped (parsley, chives, or basil)

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Chop about 2 cups of leftover or fresh veggies into bite-sized pieces. If using raw veggies, sauté them first by heating 1 tablespoon olive oil in your skillet over medium heat, add onion and garlic, and cook until softened, about 3-4 minutes.
  3. Add leftover veggies to the skillet with the onion and garlic, stirring occasionally for 3-5 minutes until warmed through and lightly caramelized.
  4. Whisk the eggs and milk in a bowl until well combined and slightly frothy. Season with salt and pepper.
  5. Pour the egg mixture evenly over the veggies in the skillet, tilting the pan gently to distribute eggs.
  6. Sprinkle cheese evenly over the top.
  7. Transfer the skillet to the preheated oven and bake for 15-18 minutes, or until eggs are set and the top is lightly golden with a slight jiggle in the center.
  8. Remove from oven and let rest for 3-5 minutes to settle.
  9. Garnish with fresh herbs before serving.

Notes

Use organic eggs for richer flavor. If skillet handle is not oven-safe, wrap it in foil or use a pan lid. Avoid opening the oven door too early to prevent deflation. Broil for 1-2 minutes at the end for extra crispness if desired. Adapt with dairy-free milk and cheese or nutritional yeast for vegan version. Leftovers store well in fridge up to 3 days and freeze well.
