Instructions to Prepare Make-Ahead Baked Greek Omelet

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C) and grease an 8×8-inch or 9×9-inch baking dish with butter or non-stick spray.

Heat olive oil in a skillet over medium heat. Add onion and cook for 2–3 minutes until softened. Add spinach and cook until wilted. Remove from heat and let cool slightly.

FAQs

Can I prepare a baked Greek omelet the night before?

Yes, you can mix all the ingredients, pour them into a greased baking dish, cover it tightly, and refrigerate overnight. In the morning, bake it fresh as directed, adding about 5–10 extra minutes to the baking time since it starts cold.

How do you keep a baked omelet from getting watery?

Drain tomatoes and olives well before adding them, and use fresh spinach instead of frozen. Allow the omelet to cool slightly after baking so it sets properly and holds its texture.

Absolutely. You can add cooked chicken, turkey sausage, or even lean ground beef for extra protein. Make sure the meat is fully cooked and drained before mixing it in with the eggs.

What kind of cheese works best for a baked Greek omelet?
