This easy vegan frittata without eggs is crispy on the outside, tender and moist on the inside, and tastes just as good as a regular egg frittata! It’s great for meal prep, and works as a healthy breakfast, lunch, or light dinner.
Heat Oil, Onions, Add Vegetables: Heat the olive oil in an oven-proof skillet over medium to medium high heat. Add the onion and saute for 3-5 minutes until lightly brown.
Bake for 35-40 minutes at 375 degrees F (180 C) until this vegetable frittata is set in the middle, the edges of the frittata are light brown, and the dish is slightly golden on top.
