Spinach Feta Baked Omelets Recipe

Mixing the Egg Base

In a large bowl, whisk together the eight eggs, milk, salt, and pepper until the mixture is uniform and slightly frothy. Fold in the cooled spinach‑onion mixture, crumbled feta, and, if using, halved cherry tomatoes. The batter should look speckled with green and white flecks.

Baking the Omelet

1. Preheat the Oven. Set your oven to 375°F (190°C) and let it fully heat while you finish the batter. A consistent temperature ensures the omelet rises evenly.
2. Grease the Baking Dish. Lightly coat a 9‑inch square baking dish with a drizzle of olive oil. This prevents sticking and adds a subtle crisp to the edges.
3. Pour & Smooth. Transfer the egg mixture into the prepared dish, spreading it with a silicone spatula so the surface is level. You should see small pockets of feta throughout.
4. Bake Until Set. Place the dish in the oven and bake for 20‑25 minutes, or until the top is golden‑brown and a toothpick inserted in the center comes out clean. The edges should be firm but the interior remains soft.
5. Rest & Garnish. Remove from the oven and let the omelet rest for 5 minutes. This short rest lets the steam finish cooking the center and makes slicing easier. Sprinkle fresh dill or parsley on top for color and freshness.

Serving the Dish

Cut the baked omelet into generous wedges and serve immediately while warm. Pair with toasted sourdough, a crisp green salad, or a side of roasted potatoes for a complete brunch. The omelet stays tender even after a short cooling period, making it perfect for family-style serving.
