Crustless quiche with spinach and Gruyere

This crustless quiche is airy, custardy, and naturally gluten-free. Gruyere adds a nutty richness while spinach brings color and nutrition. It’s perfect for brunch or a light dinner with salad.

The secret is whisking in air and baking gently. Sauté spinach to remove moisture; excess water can lead to a soggy quiche. If you prefer stronger cheese, mix Gruyere with a little parmesan for more sharpness.

Serve warm or at room temperature. Leftovers reheat well and make a great lunch.
