Crusty fish cutlets with a punchy lemon-garlic-chilli marinade are the perfect way to elevate any white-fleshed fish — cod, whiting, kingfish, mahi-mahi, even barra. Marinate, sear, eat. 90 minutes start to finish (mostly marinate time), restaurant-quality result.

Pairs with a fresh garden salad + a glass of cold sav blanc. Camp dinner that doesn't feel like camping.

• 4 fish cutlets (200-250g each), washed + dried with paper towel
• Juice + zest of 1 lemon
• 1 tsp caster sugar
• 2 tsp sea salt
• 2 cloves garlic, sliced thin
• 1 fresh green chilli (or red), seeded + finely chopped (or 1 tsp chilli flakes)
• 1-2 tbsp olive oil (plus extra for cooking)
• One herb only (don't combine — they overpower each other):
  • 2 tbsp fresh dill, OR
  • 2 tbsp fresh basil, OR
  • 2 tbsp fresh parsley, OR
  • 2 tbsp rocket leaves, finely chopped, OR
  • 2 tbsp fresh coriander
• Optional: 1 tsp grated fresh ginger (excellent with coriander)

Fish suggestions: any firm white fish cutlet works — cod (Murray cod, blue-eye trevalla), whiting, kingfish, mahi-mahi, snapper, barramundi, jewfish.

To serve: fresh garden salad, lemon wedges, crusty bread, drizzle of extra olive oil.

1. Make the marinade. In a shallow dish that will fit the fish in a single layer, combine the lemon juice + zest, sugar, salt, sliced garlic, chopped chilli, oil + your chosen herb. Mix well.

2. Marinate the fish. Place the cutlets in the marinade, turning to coat both sides. Cover (foil or cling wrap) + refrigerate for AT LEAST 1 hour (3 hours is even better — won't over-marinate at this acid level).

3. Heat the grill. Hot — really hot. Smoking-hot for the proper crust. On a campfire: well-established hot coal bed.

4. Oil the grill with a paper towel dipped in oil — prevents sticking.

5. Cook the fish. Lay the cutlets on the grill. Don't move them for 4-5 minutes. They should release from the grill when they're properly seared. If they stick, give them another 30 seconds.

6. Flip ONCE. Cook another 4-5 minutes on the second side. The flesh should flake easily with a fork. Internal temp 60°C if you want to thermometer-check.

7. Rest 1 minute before plating.

8. Plate up with a generous drizzle of fresh olive oil over the fish, garnish with extra herb sprigs + a lemon wedge. Serve immediately.

• One herb at a time. The recipe specifies single herb on purpose — combinations turn muddy + lose distinctive flavour. Pick the one that suits your fish + side dishes
• Best herb pairings:
  • Dill — perfect for salmon, trout, ocean trout
  • Basil — Mediterranean style; works on snapper, mahi-mahi, kingfish
  • Coriander + ginger — Asian style; brilliant on barramundi, blue-eye trevalla
  • Parsley — universal; never wrong
  • Rocket — peppery + fresh; great on whiting, flathead
• Don't over-marinate — beyond 4 hours the lemon juice starts to "cook" the fish (ceviche-style), changing the texture. 1-3 hours is the sweet spot
• Fillet vs cutlet: works equally well on fillets. Reduce cooking time to 2-3 minutes per side for a 2cm thick fillet
• Skin-on: if your fish is skin-on, cook skin-side DOWN first for crispy skin (5-6 minutes) then briefly flesh-side
• Camp BBQ flat plate: works fine but won't get the same char as a grill
• Pan-fry version: hot pan + oil, 4 mins per side, baste with melted butter at the end for extra richness
• Wine pairing: dry sav blanc or pinot grigio for white herbs; chilled rosé with chilli versions

The 5-minute fish recipe that always impresses. Fresh fish + bright herb + lemon + chilli + char from a hot grill = restaurant quality with almost no effort. Marinate while you set up camp; cook just before eating.

Make this a few times + you'll have an instinct for which herb suits which fish — the variations become your own. The whole world of grilled fish opens up from this one simple technique.
