Easy Savory Cauliflower & Red Onion Quiche with Basil & Rosemary
This crustless or classic-crust quiche is packed with tender roasted cauliflower, sweet caramelized red onions, and fragrant herbs like basil and rosemary. It’s creamy, cheesy, and satisfying — yet light enough for a Mediterranean-inspired meal. Serve warm or at room temperature with a green salad or tomatoes on the side.
