Common Mistakes to Avoid

- Skipping the moisture removal: If you don’t squeeze out the excess moisture from the spinach, your quiche may turn out watery. Make sure to thaw and press the spinach well before using it.
- Overcooking the mushrooms: Cooking mushrooms too long can lead to a rubbery texture. Sauté them just until their moisture has evaporated for the best flavor and consistency.
- Not greasing the pan: Forgetting to grease your pie plate can cause sticking. Always brush it with oil to ensure easy removal of your crustless quiche.
- Improper egg mixture blending: If you don’t whisk the eggs thoroughly with other ingredients, you might end up with uneven flavors. Mix until well combined for a consistent taste.
- Ignoring cooking time: Baking for too long can dry out your quiche. Keep an eye on it and check for doneness when it starts turning golden brown.
