Preheat your oven to 375°F (190°C) to ensure it’s hot and ready for baking.
In a medium-sized baking dish, evenly spread the halved cherry tomatoes and thinly sliced red onion across the bottom.
Drizzle 1 tablespoon of olive oil over the vegetables and generously sprinkle with salt, pepper, and dried oregano. Gently toss to ensure the veggies are well-coated with the seasoning.
Crumble the feta cheese evenly over the tomato and onion mixture, covering the surface as much as possible.
Using the back of a spoon, create four small wells in the feta and vegetable mixture. Carefully crack one egg into each well, taking care not to break the yolks.
Drizzle the remaining tablespoon of olive oil over the exposed egg whites and lightly season each egg with a pinch of salt and pepper.
Evenly scatter the halved Kalamata olives on top of the dish, adding a salty bite and color.
Place the baking dish in the preheated oven and bake for 20-25 minutes. Keep an eye on it and bake until the egg whites are set, but the yolks remain slightly runny (adjust the time according to your desired yolk consistency).
Once fully baked, remove the dish from the oven and allow to cool for just a couple of minutes.
Before serving, garnish the dish with freshly chopped parsley for a festive touch.
Notes
Serve directly from the baking dish for a rustic feel, accompanied by warm pita or crusty bread.
