Keto Rosemary Garlic Cauliflower Mash with Olive Oil Drizzle – Perfect Easter Dinner Side

Holiday meals often call for something a little more elevated—but that doesn’t mean we need to sacrifice our keto goals to make it happen. When we started planning our spring table this year, we knew we wanted a side dish that would feel special enough for Easter dinner but still be light, clean, and aligned with our low-carb lifestyle.

That’s when this rosemary garlic cauliflower mash came into play. It’s simple in ingredients but deeply flavorful, with slow-roasted garlic and fresh rosemary doing the heavy lifting. The result is a silky mash that brings richness, elegance, and that herby depth we usually only find in restaurant dishes.

We also love that this mash doesn’t need much to shine. A swirl of high-quality olive oil at the end adds the perfect finish—both visually and flavor-wise. Paired with lamb, ham, or roasted poultry, it rounds out the plate without feeling too heavy.

This recipe has become one of our go-tos for spring gatherings. It’s just as at home next to a centerpiece rack of lamb as it is alongside weekday leftovers. It’s comfort food, yes—but comfort food that feels bright, nourishing, and just right for the season.
