This oven-baked frittata blends caramelized zucchini, red peppers, cherry tomatoes, and baby spinach with a creamy mixture of eggs, feta, and Parmesan. Roasting the vegetables first enhances their natural sweetness and texture. Finished with fresh basil, this dish offers a light yet hearty meal perfect for any time of day.

Easy to prepare with straightforward steps, it’s ideal for a gluten-free and vegetarian option. Variations include swapping cheeses or adding potatoes for extra heartiness. Serve warm or room temperature for best flavor.

I remember the first time I made this roasted vegetable frittata—how the smell of caramelized peppers and onions filled my kitchen and made it impossible not to sneak a taste even before it was fully cooked. It quickly became a go-to for any meal, whether brunch with friends or a cozy solo dinner.

One afternoon, unexpected guests arrived just as I was halfway through roasting the veggies, and I nervously pulled together the egg mixture. Watching everyone’s delighted faces as I served the warm frittata made that rushed moment feel like pure magic.

Ingredients

  • Zucchini, red bell pepper, onion, cherry tomatoes, spinach: Roasting these brings out a natural sweetness that elevates the frittata beyond ordinary eggs
  • Olive oil: Use good quality for a richer flavor and better caramelization
  • Sea salt and black pepper: Season simply to let the veggies shine
  • Eggs: The base that holds everything together; fresh is best here
  • Milk: Adds creaminess; dairy-free alternatives work well to keep it light
  • Feta and Parmesan cheese: They give tangy and savory depth—feel free to adjust depending on your taste or dietary needs
  • Dried oregano and thyme: These herbs whisper a hint of earthiness that complements the roasted vegetables
  • Fresh basil: Garnishing with basil brings brightness just before serving

Instructions

The Part Where Magic Happens:
Start by roasting the vegetables until they smell sweet and just begin to turn golden, filling your kitchen with autumn warmth. As they soften, whisk your eggs with cheese and herbs, noticing the creamy texture coming together. Then fold in the goodies and pour everything into your skillet—the colors swirling in promise of a cozy meal. Baking gently until set, you’ll hear soft crackling from the oven, the edges turning a delicate gold. Cooling slightly, the frittata rests, ready to be sliced and shared.
