Ingredients:
- 2 Tbsp Extra Virgin Olive Oil
- 1 medium Yellow Onion, finely diced
- 2 medium Zucchini (Courgette), trimmed, quartered lengthwise, and sliced
- 1 cup Cherry or Grape Tomatoes, halved
- 2 cloves Garlic, minced or crushed
- 1/2 tsp Dried Oregano
- 1/2 tsp Kosher or Sea Salt (plus more for seasoning)
- 1/4 tsp Black Pepper, freshly ground
- 8 Large Eggs, room temperature
- 1/4 cup Whole Milk or Cream
- 1/4 cup Whole Milk Ricotta Cheese
- 1/4 cup Freshly grated Parmesan Cheese
- 1/4 cup Fresh Basil, chopped, plus extra for garnish
Instructions:
- Preheat the oven to 350°F (180°C). Prepare the zucchini: Slice the zucchini and place it in a colander. Toss lightly with 1/2 tsp of salt and let it sit for 10 minutes to draw out excess moisture.
- Sauté Aromatics: Heat the olive oil in a 10-inch oven-safe skillet over medium heat. Add the diced onion and sauté until soft and translucent (about 5 minutes).
- Cook Zucchini: Pat the salted zucchini dry using kitchen roll. Add the zucchini to the skillet and cook for 5-7 minutes until lightly caramelized and tender-crisp. Add the garlic, halved tomatoes, and dried oregano. Cook for 2 minutes until fragrant. Season with pepper. Remove the skillet from the heat and set aside.
- Prepare the Egg Base: In a large bowl, vigorously whisk the 8 eggs until they are pale yellow and slightly frothy. Whisk in the milk or cream, grated Parmesan, and a pinch of salt and pepper.
- Incorporate Ricotta and Basil: Gently stir in the ricotta cheese and chopped fresh basil. Avoid over-mixing.
- Set the Base: Ensure the cooked vegetable mixture is evenly distributed in the skillet. Pour the egg base over the vegetables. Return the skillet to the hob over medium-low heat and cook, undisturbed, for 5–7 minutes, until the edges of the frittata are set and the centre is just barely liquid.
- Finish in the Oven: Carefully transfer the skillet to the preheated oven. Bake for 12–15 minutes, or until the frittata is puffed, golden brown around the edges, and set in the center.
- Rest and Serve: Remove the frittata from the oven and let it rest in the pan for 10 minutes. Gently loosen the edges and slide it out onto a cutting board. Garnish with extra fresh basil, slice into 6 wedges, and serve warm or at room temperature.
