What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1To prevent a watery bake, squeeze any excess moisture from the sautéed spinach before adding it to the dish.
- 2For extra fluffiness, let the whisked egg mixture rest for 2-3 minutes before pouring it over the vegetables.
- 3Use a glass or ceramic baking dish for even heat distribution and a nicely set center.
- 4Test doneness by inserting a knife near the center; if it comes out clean, the bake is ready.
- 5Let the bake rest for 5 minutes after coming out of the oven so the eggs firm up for clean slices.
- 6You can prep the sautéed vegetables a day ahead and store them in the fridge to speed up morning assembly.
- 7For a golden top, switch the oven to broil for the last minute of baking, watching closely to avoid burning.
