Step-by-Step Instructions

Creating the perfect oven baked frittata recipe requires attention to detail, but don’t worry the process is straightforward and forgiving.

Preparation Phase

1. Preheat your oven to 325°F. This lower temperature ensures even cooking without a rubbery texture.
2. Heat 1 teaspoon olive oil in your 10-inch oven-safe frying pan over medium heat. Add the chopped onions and sauté for about 5 minutes until soft and translucent. This step develops sweetness and eliminates any harsh raw onion flavor. Remove from heat and let cool.
3. While onions cool, crack 6 eggs into a mixing bowl. Add the milk and dried oregano. Using a whisk or electric mixer on low speed, beat until well combined but not frothy. Over-beating can make your frittata tough, so gentle mixing is key.
4. Prepare your avocados on a clean cutting board using a sharp chef’s knife. Cut them into ½-inch dice. Transfer to a small bowl and gently toss with lemon juice this prevents browning and adds brightness.

Assembly and Baking

5. Grease your frying pan well with butter or cooking spray. This is crucial for easy serving later.
6. Evenly distribute the diced avocado across the bottom of the pan. Scatter the crumbled feta cheese, chopped Kalamata olives, roasted red pepper pieces, and cooled sautéed onions over the avocado. This layering technique ensures every slice gets a perfect distribution of ingredients.
7. Carefully pour the egg mixture over the vegetables and cheese. Pour slowly from the center, allowing the mixture to spread naturally and fill all the gaps between ingredients. Avoid stirring let the ingredients settle naturally for the best texture.
8. Transfer the pan to your preheated oven. Bake for approximately 50 minutes, or until the center is almost firm but still slightly jiggly. The frittata will continue cooking from residual heat after you remove it.
9. Let the frittata cool in the pan for 10-15 minutes. This resting period allows it to set completely, making slicing much easier. Run a knife around the edges before cutting into wedges.
