Broccoli Cheddar Crustless Quiche

A protein-packed, low-fat crustless quiche that combines tender broccoli and melted reduced-fat cheddar with egg whites and Greek yogurt. The result is a custardy, savory pie that's naturally gluten-free and works for breakfast, lunch, or light dinner. This version skips the traditional crust to reduce calories while keeping the comfort-food appeal. Serve warm or at room temperature.

Tips

Microwave broccoli until just tender to avoid releasing excess moisture that can make the quiche watery.

Tip 2

For easier slicing, let the quiche cool 10 minutes before cutting into wedges.

Common Mistakes

FAQ

Can I use whole eggs instead of egg whites?

Yes. Use 6 whole eggs. The quiche will be richer and slightly higher in fat. Whisk and combine the same way.

Can I freeze this quiche?

Yes. Cool completely, wrap tightly in plastic wrap, and freeze up to 2 months. Thaw overnight in the fridge and reheat at 300 F for 15-20 minutes.

What if my quiche is watery after baking?

Broccoli may have released excess moisture. Drain it more thoroughly after microwaving. A slightly loose custard firms as it cools.
