This aromatic grilled turkey offers a sophisticated twist on the traditional roast, perfect for those looking to free up oven space during a celebration or Sunday gathering. The bird is infused with a fragrant rub of toasted fennel, coriander, and black peppercorns, which provides a savoury depth that pairs beautifully with the natural sweetness of the meat. By cooking the turkey over indirect heat on the barbecue, you achieve a wonderfully crisp skin and succulent interior with a subtle hint of char.
A dairy-free gravy serves as the crowning glory of this dish, enriched by the caramelised juices of roasted parsnips, carrots, and celery. Finished with a touch of sherry vinegar and fresh thyme, the sauce is bright and complex rather than overly heavy. Serve this centrepiece with seasonal greens and roasted potatoes for a truly impressive homemade meal that is naturally lighter but remains deeply comforting.

How to make Grilled Turkey with Toasted Fennel and Coriander and Fresh Thyme Gravy
Let turkey stand at room temperature 30 minutes.
Prepare barbecue (medium heat) for indirect grilling. If using charcoal grill, light briquettes in chimney. Remove top grill rack. Place briquettes at left and right sides of bottom rack, leaving centre empty (you may need to light additional briquettes in chimney to replenish during grilling time). Replace top grill rack. If using 3-burner gas grill, light burners on left and right, leaving centre burner off. If using 2-burner gas grill, light burner on just 1 side.
Toast fennel seeds, coriander seeds, and peppercorns in medium skillet over medium heat until fragrant and fennel seeds begin to darken, 2 to 3 minutes. Pour spices into spice grinder or small coffee mill; cool. Grind spices finely. Transfer to small bowl; mix in coarse salt.
Brush turkey all over with oil. Sprinkle inside and out with spice mixture. Spread carrots, celery, parsnips, onion, and thyme in 13x9x2-inch metal roasting pan. Place turkey, breast side down, on vegetables.
Place pan with turkey on rack over unlit portion of grill. Cover grill. Insert stem of instant-read thermometer into hole in hood and maintain temperature as close as possible to 177°C by opening vents to increase temperature and closing vents to reduce temperature. Cook turkey 1 hour. Rotate pan. Using oven mitts, turn turkey, breast side up. Cover grill and continue cooking turkey until instant-read thermometer inserted into thickest part of thigh registers 74°C, covering any parts of turkey that are browning too quickly with foil, about 1 1/2 hours longer.
Transfer turkey to platter. Tent with foil and let rest 30 to 45 minutes (internal temperature will rise 5 to 10 degrees).
Strain pan juices into large measuring cup, pressing to extract as much liquid as possible. Spoon off fat that rises to surface into 1-cup measuring cup and, if necessary, add enough butter to fat to measure 120ml . Add enough chicken broth to degreased juices to measure 950ml .
Heat turkey fat in large saucepan over medium-low heat. Whisk in flour. Cook roux until deep golden brown (like dark peanut butter), whisking often, about 20 minutes. Gradually whisk in broth mixture. Boil until gravy thickens enough to coat spoon, whisking often, about 5 minutes. Whisk in vinegar and thyme. Season gravy to taste with coarse salt and pepper.
Serve turkey with gravy.
