Lightly coat a 2-quart casserole dish or 9 x 9-inch baking dish with olive oil or cooking spray to prevent sticking.

Evenly distribute the roughly chopped baby spinach in the prepared dish.
04 -
Crack the eggs into a medium bowl and pour evenly over the spinach layer.

Sprinkle the finely chopped sun-dried tomatoes over the eggs. Season with salt and freshly ground black pepper to taste.

Crumble feta cheese evenly across the egg mixture, then scatter fresh herbs on top.

Bake in the preheated oven until egg whites are set and yolks reach desired doneness: 15–20 minutes for jammy yolks, 20–30 minutes for firm yolks. Begin checking at 15 minutes and then every 5 minutes thereafter by gently pressing the yolk to test firmness.

Allow the dish to rest for about 5 minutes after baking. Optionally, remove any white film from yolks by gently sliding it to one side with a small knife. Garnish with additional freshly torn basil before serving.
