Creamy Keto Dill Cucumber & Avocado Salad

Creamy Dill Cucumber and Avocado Salad in a white bowl with red onion and fresh dill

We made this Creamy Dill Cucumber & Avocado Salad on a hot afternoon when nothing sounded better than something crisp, cool, and creamy. It was one of those days where the grill was fired up, the drinks were chilled, and we wanted a side dish that felt indulgent without being heavy. This one came together in minutes and immediately earned a spot in our summer salad lineup.

We used what we had on hand—fresh cucumbers from the garden, ripe avocado, and a generous handful of dill that needed to be used up. Instead of a typical vinaigrette, we opted for a tangy sour cream base and added lemon juice to brighten things up. It’s become our go-to when we want something hydrating and refreshing but still full of rich, satisfying flavor.

What makes this salad so perfect for keto eaters is its balance of healthy fats and fiber with minimal carbs. The avocado adds creaminess and bulk, the cucumbers give that clean crunch, and the red onion brings just the right amount of sharpness. It pairs perfectly with grilled proteins but also holds its own as a light lunch.

This dish is proof that simple ingredients, when paired just right, can be surprisingly elegant. We love bringing it to summer potlucks or setting it out at a BBQ—it always disappears fast, and no one misses the pasta or potatoes.
