Ingredients
Whole Grilled Mackerel with Fennel and Dill is a recipe built on good technique and well-sourced ingredients. The method is straightforward; the result depends on paying attention to the details. Fresh mackerel, with its rich, oily flesh, stands up well to direct heat grilling, developing a crisp skin while staying tender inside. The subtle anise notes from the fennel and the bright, herbaceous lift of dill complement the fish without overpowering it, making for a balanced and clean flavour profile.
Cooking whole fish over fire requires a steady approach and the right tools — a chimney starter to get the coals just right, a reliable instant-read thermometer to monitor doneness, and a grill basket to keep the fish intact. Resting the fish after cooking allows the juices to redistribute, ensuring a moist finish. This recipe is a reminder that everyday BBQ doesn’t need to be complicated or reliant on heavy sauces; it’s about quality ingredients, respect for the cooking process, and a thoughtful combination of flavours.
Using seasonal, homegrown produce and cooking simply over fire is at the heart of what we do. This dish embodies those principles — clean, whole-food cooking that feels as natural as it does satisfying. It’s a recipe that rewards patience and care, proving that with the right technique and ingredients, BBQ can be both approachable and refined.

Prepare the Grill for High Heat
Set up the Weber Master-Touch for a direct high-heat cook. Fill a chimney starter with Weber briquettes and light. Once the briquettes are fully ashed over (grey and glowing), pour them evenly over the charcoal grate. Place the cooking grate in position and allow it to preheat for 10 minutes with the lid on, aiming for a grate temperature of 230–260°C. Clean the grate thoroughly with a wire brush and then, using a folded paper towel dipped in olive oil and held with tongs, oil the hot grate to create a non-stick surface.
Prepare the Mackerel
Pat the whole mackerel dry with kitchen paper. Using a sharp knife, score the skin three or four times on each side, cutting down to the bone. This helps the heat penetrate quickly and prevents the skin from tearing. Rub the fish generously, inside and out, with olive oil, then season heavily with salt and pepper. Stuff the cavity of each fish with the sliced fennel, dill stalks, and two or three lemon slices.
Grill the Fish
Place the prepared mackerel directly over the hot coals. If using a fish basket, secure the fish inside it before placing it on the grate. Close the lid, ensuring the top and bottom vents are fully open. Grill for 6 minutes.
Flip and Finish
Using tongs or the fish basket, carefully flip the mackerel. Grill for a further 5–6 minutes. The skin should be crisp and deeply coloured. Check the internal temperature by inserting a digital thermometer into the thickest part of the fish, avoiding the bone. The fish is cooked when it reaches an internal temperature of 63°C.
Rest and Serve
Remove the mackerel from the grill and let it rest on a warm plate for 2 minutes. Garnish with the reserved fennel fronds and dill fronds. Serve immediately with a squeeze of fresh lemon.

An instant-read thermometer is the single most reliable tool for achieving precise cooking results over fire. At Smoke & Soil, we champion clean, whole-food cooking that honours seasonal ingredients and respects the natural flavours of your produce. This thermometer fits perfectly into that ethos by taking the guesswork out of doneness, allowing you to cook meats, fish, and even vegetables to perfection every time. It is indispensable for ensuring food safety, particularly with poultry, where undercooking can pose health risks. It also speeds up weeknight cooking by giving you immediate temperature feedback, so you never have to second guess whether your food is ready. Using an instant-read thermometer correctly is as important as owning one. Insert the probe into the thickest part of the meat, avoiding bones which conduct heat differently and give false readings. Take multiple readings to confirm consistency, especially with larger cuts. This tool is not just for meat; it can help you nail the perfect temperature for everything from bread to custards, supporting a wide range of fire-cooking techniques. It is a straightforward way to elevate your BBQ game without fuss or guesswork. The instant-read thermometer embodies the no-nonsense, practical approach Smoke & Soil stands for. It is a tool that rewards attention to detail and encourages respect for the ingredients and the cooking process. Investing in a good quality, fast-reading model will pay dividends in flavour, texture, and safety. It also complements other techniques like carryover cooking and indirect heat methods, making it a versatile addition to your BBQ toolkit.
