Is this recipe gluten-free?

Yes, this Caramelized Onion and Goat Cheese Crustless Quiche is naturally gluten-free, making it perfect for those with gluten sensitivities or celiac disease.

Can I add meat to this recipe?

Certainly! Cooked and crumbled bacon, prosciutto, or rotisserie chicken work beautifully with the caramelized onions and goat cheese. Add about ½ cup of your protein of choice when assembling the quiche.

Why is my quiche watery?

Excess moisture usually comes from either the onions not being caramelized long enough (releasing water during baking) or the quiche being underbaked. Ensure you cook the onions until they're jam-like in consistency and bake until the center is just set.

Can I make mini versions of this crustless quiche?

Definitely! Distribute the mixture among a greased muffin tin, filling each cup about ¾ full. Reduce baking time to 20-25 minutes for perfect individual-sized quiches – ideal for meal prep or parties!

How can I tell when my onions are properly caramelized?

Properly caramelized onions should be significantly reduced in volume (about ¼ of their original size), uniformly golden-brown, and have a soft, jam-like consistency. They should taste sweet with no remaining sharp onion flavor.
