Plank Baked Rainbow Trout: A Taste of the Pacific Northwest

The scent of cedar and the subtle sweetness of perfectly cooked fish… It takes me back to childhood summers spent on Puget Sound. My grandfather, a seasoned fisherman, would often prepare rainbow trout this way after a successful day on the water. We’d gather around the picnic table, the salty air mingling with the smoky aroma, and enjoy a meal that tasted of sun-drenched days and the pure, wild beauty of the Pacific Northwest. This plank-baked trout isn’t just food; it’s a delicious memory.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 2
• Dietary Type: Pescatarian, Gluten-Free, Dairy-Free

Ingredients

• 2 lbs rainbow trout, cleaned with head on
• 1 tablespoon olive oil
• ½ teaspoon salt
• ½ teaspoon pepper
• Two untreated cedar planks, about ¾ inch thick and 12 to 15 inches long

Equipment Needed

• Oven
• Large bowl or container for soaking planks
• Aluminum Foil

Instructions

1. Begin by preparing the cedar planks. Place the planks into cool water and allow to soak for at least 2 hours, and up to overnight. Soaking is crucial; it prevents the planks from catching fire in the oven and infuses the fish with that signature smoky cedar flavor. I usually weigh the planks down with a heavy pot to ensure they are fully submerged.

2. Preheat your oven to 375 degrees F (190 degrees C). This moderate temperature ensures that the fish cooks evenly without drying out.

3. While the oven is preheating, prepare the rainbow trout. Brush the trout, both inside and out, generously with olive oil. This helps to keep the fish moist and prevents it from sticking to the plank.

4. Season the trout liberally, both inside and out, with salt and pepper. Don’t be shy with the seasoning! It’s essential for bringing out the natural flavors of the fish.

5. Remove the soaked cedar planks from the water and pat them dry with a paper towel. Place the trout onto the planks, belly down and open. The fish should lay flat on the plank. This position allows the heat to circulate evenly around the fish.

6. Wrap foil around both the fish and the plank. This step is important! It helps to retain moisture during cooking.

7. Place the planks in the preheated oven for approximately 15 to 20 minutes. The exact cooking time will depend on the thickness of the fish and your oven, so keep an eye on it.

8. After 15-20 minutes, remove the planks from the oven. Carefully unwrap the foil. To check for doneness, insert a fork into the thickest part of the fish. If the flesh flakes easily, it’s done. The internal temperature should reach 145°F (63°C).

9. Allow the fish to sit for 5 to 10 minutes before serving. This resting period allows the juices to redistribute, resulting in a more tender and flavorful fish. You can serve the fish as is, directly on the plank, or debone it before serving.

Expert Tips & Tricks

• Soaking Time is Key: Don’t skimp on soaking the cedar planks. A well-soaked plank is crucial for preventing flare-ups and imparting the desired cedar aroma. If you’re short on time, you can try microwaving the planks in water for a few minutes to speed up the process.
• Don’t Overcook: Rainbow trout is delicate and can easily dry out. Keep a close eye on it during cooking and remove it from the oven as soon as it’s done.
• Flavor Enhancements: Get creative with your seasonings. Try adding lemon slices, fresh herbs (such as dill, parsley, or thyme), or a sprinkle of garlic powder to the inside of the trout.
• Cedar Plank Alternatives: If you don’t have cedar planks, you can use other types of wood, such as alder or maple. Just be sure to soak them thoroughly before use. Alternatively, you can bake the trout on a baking sheet lined with parchment paper, but you’ll miss out on the signature cedar flavor.

Serving & Storage Suggestions

Serve the plank-baked rainbow trout directly on the cedar plank for a rustic presentation. Garnish with fresh herbs, lemon wedges, and a drizzle of olive oil. This dish pairs well with grilled vegetables, roasted potatoes, or a simple green salad.

Leftover cooked rainbow trout can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, wrap the fish in foil and bake in a preheated oven at 350°F (175°C) until warmed through. Avoid microwaving, as it can dry out the fish.

FAQs (Frequently Asked Questions)

Q: Can I use different types of fish?

A: Yes, while this recipe is specifically for rainbow trout, you can also use other types of fish such as salmon, steelhead, or cod. Adjust the cooking time accordingly based on the thickness of the fish.

Q: What if I don’t have cedar planks?

A: If you don’t have cedar planks, you can use alder or maple planks as substitutes. Be sure to soak them thoroughly before use. As an alternative, bake the trout on a baking sheet lined with parchment paper, but you’ll miss the cedar flavor.

Q: How do I know when the fish is cooked through?

A: The fish is cooked through when the flesh flakes easily with a fork and the internal temperature reaches 145°F (63°C).

Q: Can I prepare this dish ahead of time?

A: You can prepare the trout by brushing it with oil and seasoning it up to a few hours in advance. Store it covered in the refrigerator until ready to bake. However, it’s best to cook the fish fresh for optimal flavor and texture.

Q: Can I grill the trout instead of baking it?

A: Absolutely! Plank-baked trout is delicious grilled. Preheat your grill to medium heat and place the soaked cedar planks directly on the grates. Cook the fish, covered, for about 15-20 minutes, or until it’s cooked through. Keep a close eye on the planks to prevent them from catching fire.
