✅ Q & A Section

Q: Why is this quiche crustless?

A: Skipping the crust makes it faster, lighter, gluten-free, and lower in carbs—while still flavorful and filling.

---

Q: Can I use frozen spinach?

A: Yes! Thaw it completely and squeeze out all excess moisture to prevent a watery quiche.

---

Q: Can I make it ahead of time?

A: Absolutely. Bake it fully, cool, and refrigerate for up to 3 days. Reheat at 325°F (165°C) until warm.

---

Q: How do I know when it’s done?

A: The center should be set and not jiggly. A knife inserted in the middle should come out mostly clean.

A: Yes! Popular additions include:

• Mushrooms

• Sun-dried tomatoes
