This recipe delivers a vibrant, orange-pink fillet that is perfectly flaky and glistening under a rich lemon garlic butter glaze.

Essential Ingredients for the Best Cedar Planked Rainbow Trout
To achieve that restaurant-quality finish, every ingredient in this cedar planked rainbow trout recipe serves a specific culinary purpose:
- 1 Large Rainbow Trout Fillet (approx. 1.5 lbs / 680g): Choose a fillet with skin-on to help hold the moisture and provide a sturdy base on the wood.
- 1 Untreated Cedar Plank: The foundation of the dish. Ensure it is food-grade and has been soaked for at least 2 hours to prevent flare-ups.
- 4 tbsp (56g) Unsalted Butter: Provides the fat needed to keep the lean trout succulent during the high-heat grilling process.
- 3 Cloves Fresh Garlic: Minced finely to infuse the butter with a pungent, savory depth.
- 1 Large Lemon: Half will be sliced into wheels for charring, and the other half juiced for the bright acidity in the glaze.
- Fresh Dill Sprigs: A classic pairing for trout that adds a feathery texture and herbaceous aroma.
- Sea Salt Flakes & Cracked Black Pepper: Coarse salt provides a satisfying crunch and pop of flavor, while fresh pepper adds a mild heat.
How to Make Perfect Cedar Planked Rainbow Trout Step-by-Step
1. The Critical Cedar Plank Soak
Success begins hours before you light the grill. You must soak your cedar plank in water for a minimum of 2 hours. This prevents the wood from catching fire and creates the steam necessary to keep the cedar planked rainbow trout moist. Weigh the plank down with a heavy bowl or pot to keep it fully submerged.
2. Prepare the Lemon Garlic Butter Glaze
In a small saucepan or microwave-safe bowl, melt the butter. Stir in the minced garlic and 1 tablespoon (15ml) of fresh lemon juice. This lemon garlic butter glaze is the secret to that glistening, golden finish seen in our recipe photos. Set aside a small amount for a final drizzle before serving.
3. Seasoning for Maximum Flavor
Pat the trout fillet dry with paper towels—this helps the butter adhere. Generously brush the top of the fish with the garlic butter. Sprinkle a heavy layer of sea salt flakes and cracked black pepper across the entire surface. Tuck 3-4 lemon wheels alongside or slightly under the edges of the fish for that charred citrus aesthetic.
4. Mastering the Grill Cues
Preheat your grill to medium-high heat (about 400°F / 204°C). Place the prepared plank directly on the grates. Close the lid and cook for 12-15 minutes. Visual Cue: The trout is done when the flesh is opaque and flakes easily with a fork, and the edges of the cedar plank are dark and slightly charred.
5. The Final Flourish
Remove the entire plank from the grill carefully using tongs. Immediately scatter a heavy handful of fresh green dill sprigs over the hot fish. The residual heat will slightly wilt the dill, releasing its essential oils. If you love herb-forward seafood, our lemon herb butter trout is another fantastic option.
Expert Tips for Smoky Trout Success
- Don’t Skip the Soak: An unsoaked plank will burn too quickly, potentially ruining the fish with acrid smoke.
- Temperature Check: Use an instant-read thermometer. Aim for an internal temperature of 145°F (63°C) at the thickest part of the fillet.
- Keep the Lid Closed: Every time you peek, you lose the trapped smoke that gives the trout its distinct cedar flavor.
- Skin-On is Best: Even if you don’t eat the skin, leaving it on prevents the fish from falling apart when you serve it from the plank.
Storage, Reheating, and Freezing
Storage: Store any leftover cedar planked rainbow trout in an airtight container in the refrigerator for up to 2 days. The smoky flavor often intensifies overnight!
Reheating: To maintain the flaky texture, reheat the trout in a 275°F (135°C) oven covered with foil until just warmed through. Avoid the microwave, as it can make the delicate fish rubbery.
Freezing: While possible, we do not recommend freezing cooked trout as the texture will degrade significantly. It is best enjoyed fresh off the grill.
What to Serve With Cedar Planked Trout
This smoky main dish pairs beautifully with light, vibrant sides. We recommend a crisp tomato burrata salad to cut through the richness of the butter. Other great options include grilled asparagus, roasted fingerling potatoes, or a simple quinoa pilaf. For a different nutty crust, you might also enjoy our pistachio crusted rainbow trout.
Frequently Asked Questions
