Topped with crumbled feta cheese, it’s baked until just set and golden, offering a tender, flavorful dish perfect for breakfast, brunch, or a light dinner. Versatile and gluten-free, this hearty meal provides balanced protein and vibrant vegetables.

I remember the first time I tried making this roasted vegetable frittata; the colorful veggies roasting in the oven filled the kitchen with such a warm, inviting aroma that I was hooked instantly.

One weekend when unannounced guests showed up, I whipped this up quickly and it saved the day with its bright flavors and simple preparation.

Ingredients

  • Cherry Tomatoes, Bell Pepper, Zucchini, Red Onion: Roasting these veggies brings out their natural sweetness and adds complexity
  • Baby Spinach: Adds freshness right before the frittata finishes cooking
  • Eggs: The binder that pulls everything together with a silky texture
  • Feta Cheese: Its tanginess contrasts beautifully with the roasted veggies; goat cheese works well too
  • Olive Oil and Herbs: Enhances flavor and helps veggies caramelize

Instructions

Preheat and Roast:
Set your oven to 400°F (200°C) and toss your chopped vegetables with olive oil, herbs, and seasonings until everything is evenly coated. Roasting them brings out a delicious caramelized aroma that fills your kitchen.
Whisk and Sauté:
Lower the oven to 350°F (175°C). Whisk eggs with milk and seasonings, then heat olive oil in a skillet. Sauté the roasted veggies with the spinach until the leaves wilt, adding freshness and vibrant green color.
Combine and Cook:
Pour the egg mixture over the veggies in the skillet and let it cook gently without stirring until the edges start to firm up. The smell of the eggs beginning to set is the hint that the magic is underway.
Add Cheese and Bake:
Sprinkle feta over the top evenly, then transfer the skillet to the oven. Bake until the center is just set, maintaining a creamy texture inside while the edges turn golden.
Rest and Serve:
Allow the frittata to cool slightly before slicing. This pause lets the flavors settle and makes serving easier.

Keeping It Fresh

Adding fresh spinach right before pouring in the eggs adds a burst of color and slight earthiness that balances the sweetness of the roasted vegetables beautifully.

When You're Missing Something

If you don't have feta on hand, goat cheese or mozzarella are great substitutes that change the flavor profile slightly but keep the creamy texture you're aiming for.
