Halibut with Peach Glaze and Pineapple-Cucumber Salsa

Recipe Note

Recipe FAQ

Why does the plank go over direct heat first?
Direction Step 1 of Smoke on the Plank specifies placing the halibut on the plank over direct heat first, then transferring to indirect once the plank begins to smoke and dry out. The direct heat ignites the surface of the soaked plank, causing the wood to begin charring and releasing smoke — this is the active smoke phase that infuses the fish with wood character. Once the plank is smoking actively, moving it to indirect heat allows the fish to finish cooking gently in the smoke environment without over-charring the plank bottom.

Why apply the peach glaze at 140°F, not at the start?
The Texas Pepper Jelly glaze contains sugar, which burns quickly at high heat and will turn bitter and black before the fish reaches safe temperature if applied too early. Waiting until 140°F — the last 5°F of the cook — allows only a brief time in the heat, which sets the glaze into a sticky, caramelized coating rather than burning it. At this point the fish is nearly done, so the glaze brushed on finishes in the same short window the fish needs to reach 145°F.

What temperature should halibut reach?
The FDA minimum safe temperature for fish is 145°F. The directions specify glazing at 140°F and removing at 145°F. Halibut is a lean, dense fish — it can go from perfectly cooked to dry and crumbling in a narrow temperature window. Pull it precisely at 145°F using an instant-read thermometer inserted into the thickest part of the fillet. Don't judge doneness by flaking alone; the visual cues for halibut are subtle and the thermometer is more reliable.

Can I use a different fish?
Yes — the recipe notes "or other whitefish." Mahi-mahi, cod, sea bass, and grouper all work well with this flavor profile. Salmon also works but its stronger flavor and higher fat content produce a different balance with the sweet glaze — the peach will complement rather than dominate as it does with halibut. Thinner fillets will cook faster; adjust timing accordingly and use the thermometer rather than time as the guide.

How far ahead can I make the pineapple-cucumber salsa?
The directions specify at least 1 hour; you can prepare it up to 24 hours in advance. Past 24 hours, the cucumber softens from the lime acid and begins to release water, diluting the salsa and making it less crisp. If making ahead, taste and adjust lime and salt just before serving — the flavors concentrate and the salt draws out more moisture over time.

Can I make this indoors?
4 out of 5 — Great in the kitchen, better on the grill. Bake the halibut on a soaked plank (or a sheet pan lined with parchment) at 350–375°F, applying the glaze at 140°F and finishing to 145°F. What you lose is the live-fire plank smoke from the outdoor grill — the oven version won't develop the same smoky wood character, but the glaze and salsa combination translates fully.

Recipe Highlights

• Soak the plank for the full hour — not less: Direction Step 1 specifies soaking the GrillPro smoking plank in water for 1 hour before cooking. An under-soaked plank ignites too quickly over direct heat and can catch fire rather than smoldering slowly. The water absorbed during the hour soak is what regulates the burn rate — it buys time for the fish to smoke before the plank is consumed. Submerge the plank fully and weight it down if necessary; it will float if not held under water.

   

• Oil the underside of the halibut, not the plank: Direction Step 4 specifies applying oil to the underside of the halibut to prevent sticking. Oiling the plank surface directly can cause flare-ups when the plank goes over direct flame. Oiling the fish bottom instead creates a non-stick barrier between the fish and the plank without introducing extra fuel to the fire. The Plowboys Fin & Feather Rub goes on the topside only — the side facing up during the cook.

   

• The lemon slices come off before the glaze goes on: Direction Smoke on the Plank Step 3 specifies removing lemon slices before brushing with glaze. The lemon is a flavor-infusing element during the smoke phase, not a garnish. Leaving the slices on when the glaze goes on would prevent the glaze from adhering to the fish surface and would create a barrier between the glaze and the fish skin. Remove them cleanly before glazing for full glaze contact across the fillet surface.

   

• Make the salsa at least 1 hour before the cook, not after: Direction Preheat & Prep Step 3 specifies covering and refrigerating the salsa for at least 1 hour. A freshly made salsa tastes raw and disparate — the lime is sharp, the onion is pungent, and the individual flavors haven't melded. After an hour of refrigeration, the lime juice has softened the onion's rawness, the salt has drawn moisture from the cucumber and pineapple, and the flavors have integrated into a cohesive condiment.
