Common Mistakes to Avoid
When making the Spinach Mushroom and Feta Crustless Quiche, it’s easy to overlook some important steps. Here are common mistakes to avoid for a perfect quiche.
- Ignoring moisture: Failing to squeeze out excess moisture from the spinach can lead to a watery quiche. Always thaw and wring out the spinach thoroughly before mixing it in.
- Overcooking mushrooms: Cooking mushrooms too long can cause them to shrink excessively. Sauté them just until they release their moisture and become tender.
- Skipping the oil: Not using enough oil can result in sticking. Make sure to brush your pie plate with cooking oil for easy removal.
- Not whisking eggs thoroughly: If you don’t whisk the eggs, milk, and cheese well, the mixture may not blend properly. Whisk until fully combined for a smooth consistency.
- Underbaking: Taking the quiche out of the oven too early can leave it runny inside. Bake until golden brown and ensure an internal temperature of 160°F.
