- Combine everything: Fold the sautéed spinach and onions, sun-dried tomatoes if using, shredded cheddar, and crumbled feta gently into the egg mixture.
- Pour and distribute: Transfer the mixture evenly into the prepared baking dish. Gently tap the dish on the counter to level the casserole.
- Bake: place in the oven and bake uncovered for 35-40 minutes, or until the casserole is set around the edges and slightly jiggly in the center. A toothpick inserted should come out clean.
