Keto Roasted Cauliflower & Olive Salad with Garlic-Herb Oil

We created this Roasted Cauliflower & Olive Salad on a weeknight when we were tired of the usual side dishes and wanted something that felt elevated but still easy. Cauliflower is one of those ingredients we always keep around, and when roasted, it transforms into something deeply savory and nutty. Add olives and tomatoes for contrast, and it becomes more than a salad—it’s a composed dish with layers of flavor.

The garlic-herb oil ties it all together. It’s a simple blend, but once the roasted cauliflower soaks it up, it adds a burst of flavor that makes the whole bowl shine. We like to serve this slightly warm or at room temperature, which makes it incredibly flexible whether it’s going alongside grilled chicken at dinner or starring in a lunch spread the next day.

What’s great about this salad is how well it holds up. The flavors deepen as it sits, and the cauliflower stays sturdy without getting soggy. We’ve made it for meal prep, brought it to barbecues, and served it warm on chilly days as a hearty side—it just works.

This salad is our go-to when we want a vegetable-forward, keto-friendly side that’s anything but basic. It’s colorful, bold, and full of Mediterranean flavor.
