Ingredients for Sheet Pan Roasted Mediterranean Vegetable Frittata

Instructions

Preheat the oven to 400°F (200°C). Line a 9x13-inch rimmed sheet pan with parchment paper or lightly grease with olive oil.
In a large mixing bowl, whisk together the eggs, milk, minced garlic, dried oregano, dried thyme, salt, and freshly ground black pepper until smooth and well combined. Set aside.
Evenly spread the zucchini slices, red bell pepper, cherry tomatoes, red onion, and baby spinach across the prepared sheet pan.
Drizzle the vegetables with the extra virgin olive oil. Toss gently to coat thoroughly, then season with a pinch of salt and pepper.
Pour the egg mixture evenly over the vegetables on the sheet pan. Sprinkle the crumbled feta cheese on top if using.
Bake for 20 to 25 minutes, or until the frittata is fully set and golden around the edges. A knife inserted in the center should come out clean.
Remove from the oven and allow to cool for 5 minutes. Garnish with fresh chopped parsley.
Slice into squares and serve warm or at room temperature. Pair with a crisp side salad or crusty whole-grain bread for a complete meal.
