Whole mackerel is one of the best fish for the BBQ — oily, robust, and able to handle direct charcoal heat without drying out. Scored and seasoned simply with olive oil, black pepper, and a touch of thyme, it crisps up beautifully over high heat while keeping the flesh moist and flaky. The natural richness of the fish stands up well to the char and smoke, making it a straightforward but satisfying choice for everyday grilling.

The addition of sharp horseradish cream cuts through the oiliness, adding a clean, vibrant contrast that lifts the dish. A squeeze of fresh lemon brings brightness and balances the flavours, keeping the whole plate fresh and grounded. This recipe embraces clean, whole-food cooking over fire — no fuss, just quality ingredients and confident technique.

Using direct heat grilling and a pair of long tongs, this dish comes together quickly and with minimal fuss, making it ideal for a simple midweek meal or a relaxed weekend cook. It’s a reminder that BBQ doesn’t have to be complicated or overdone to be rewarding; sometimes the best results come from letting good ingredients meet fire on their own terms.
