AvatarByCynthia Crase Food Storage & Preservation

Cooking salmon on a cedar plank has become a beloved technique for home cooks and chefs alike, offering a unique blend of smoky aroma and tender, flavorful fish. If you’ve ever wondered how to achieve that perfect balance of moistness and subtle woodsy essence, understanding the timing is key. Knowing how long to cook cedar plank salmon in the oven can transform your meal from ordinary to extraordinary, ensuring each bite is infused with rich, aromatic goodness.

The process of cooking salmon on a cedar plank combines traditional grilling methods with the convenience of oven cooking, making it accessible year-round. This method not only enhances the flavor but also helps keep the fish moist and tender by gently steaming it as it cooks. However, the cooking time can vary depending on factors such as the thickness of the fillet, oven temperature, and whether the plank is pre-soaked.

Before diving into the specifics, it’s important to grasp the basics of cedar plank salmon preparation and the role timing plays in achieving optimal results. Whether you’re a seasoned cook or trying this technique for the first time, understanding the nuances of cooking duration will help you create a dish that impresses both in taste and presentation. In the sections that follow, we’ll explore the ideal cooking times and tips to master cedar plank salmon in your oven

Optimal Oven Temperature and Cooking Time for Cedar Plank Salmon

Cooking cedar plank salmon in the oven requires balancing temperature and time to ensure the fish is perfectly cooked while the cedar plank imparts its distinctive smoky aroma. The ideal oven temperature typically ranges from 350°F to 400°F (175°C to 205°C), which allows the salmon to cook evenly without drying out.

The cooking time largely depends on the thickness of the salmon fillet and whether the fish is cooked from room temperature or directly from the refrigerator. As a general guideline:

  • For a fillet about 1 inch thick, cook for approximately 12 to 15 minutes.
  • Thicker fillets (1.5 to 2 inches) may require 18 to 20 minutes.
  • If the salmon is chilled, consider adding 3 to 5 extra minutes.

Using a cedar plank slightly extends the cooking time compared to direct baking because the plank acts as an insulator, moderating the heat exposure to the fish.

Step-by-Step Oven Cooking Process

To achieve the best results, follow these detailed steps:

  • Pre-soak the cedar plank: Immerse the cedar plank in water for at least 1 hour before cooking to prevent it from burning in the oven.
  • Preheat the oven: Set the temperature between 350°F and 400°F.
  • Prepare the salmon: Pat dry, season as desired, and place the fillet skin-side down on the soaked plank.
  • Place the plank on a baking sheet: This makes handling easier and catches any drippings.
  • Bake uncovered: Position the baking sheet in the center rack of the oven.
  • Check for doneness: The salmon is ready when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Cooking Time Reference Table

Salmon Thickness Oven Temperature Cooking Time Internal Temperature Target
Up to 1 inch (2.5 cm) 350°F (175°C) 12 – 15 minutes 145°F (63°C)
1.5 inches (3.8 cm) 375°F (190°C) 15 – 18 minutes 145°F (63°C)
2 inches (5 cm) or thicker 400°F (205°C) 18 – 20 minutes 145°F (63°C)

Tips for Even Cooking and Safety

Achieving perfectly cooked cedar plank salmon requires attention to several important factors:

  • Use a reliable food thermometer: This ensures the salmon reaches the safe internal temperature without overcooking.
  • Avoid opening the oven frequently: Each time the oven door opens, heat escapes, extending cooking time.
  • Rotate the baking sheet halfway: This promotes even cooking, especially if your oven has hot spots.
  • Allow resting time: After removing from the oven, let the salmon rest on the plank for 3 to 5 minutes. This helps redistribute juices and enhances flavor.
  • Check plank condition: If the cedar plank begins to char excessively, wrap the edges in foil or spritz lightly with water.

By carefully managing these elements, you can confidently cook cedar plank salmon in the oven with excellent texture, flavor, and safety.

Optimal Cooking Time and Temperature for Cedar Plank Salmon in the Oven

Cooking cedar plank salmon in the oven requires precise timing and temperature control to achieve a perfectly cooked, flavorful dish. The cedar plank imparts a subtle smoky aroma while helping to retain moisture in the salmon.

When baking cedar plank salmon, the general consensus among culinary experts is to cook at a moderate oven temperature to ensure even cooking without drying out the fish. Below are the recommended parameters:

  • Oven Temperature: 375°F (190°C) – This temperature allows the salmon to cook gently, ensuring the flesh remains tender and flaky.
  • Cooking Duration: 20 to 25 minutes – The exact time depends on the thickness of the salmon fillet and whether the fish is cooked from refrigerated or room temperature.

To provide further clarity, here is a practical guideline based on fillet thickness:

Fillet Thickness Cooking Time at 375°F (190°C) Internal Temperature Target
½ inch (1.3 cm) 15–18 minutes 145°F (63°C)
¾ inch (1.9 cm) 18–22 minutes 145°F (63°C)
1 inch (2.5 cm) or thicker 22–25 minutes 145°F (63°C)

Note on Internal Temperature: The USDA recommends cooking fish to an internal temperature of 145°F (63°C) to ensure safety and optimal texture. Use an instant-read thermometer inserted into the thickest part of the salmon to check doneness.

Preparation and Tips for Baking Cedar Plank Salmon

Proper preparation of both the cedar plank and the salmon is essential for the best results:

  • Soak the Cedar Plank: Soak the cedar plank in water for at least 1 hour before cooking. This prevents the wood from burning in the oven and generates steam that infuses the salmon with flavor.
  • Preheat the Oven: Always preheat the oven to the recommended temperature (375°F) to ensure even cooking from the start.
  • Bring Salmon to Room Temperature: Allow the salmon to sit at room temperature for 15–20 minutes before cooking to promote even heat distribution.
  • Seasoning: Apply your preferred seasoning or marinade evenly over the salmon. Common choices include lemon slices, dill, garlic, salt, and pepper.
  • Placement on the Plank: Place the salmon skin-side down on the soaked cedar plank for structural integrity and to prevent sticking.
  • Oven Rack Position: Position the oven rack in the middle to allow balanced heat circulation around the plank and salmon.

Monitoring and Adjusting Cooking Time Based on Oven Variability

Oven temperatures can vary due to calibration differences and airflow, which may influence the cooking time required for cedar plank salmon. To accommodate these variables:

  • Check Early: Begin checking the salmon’s internal temperature 5 minutes before the minimum recommended cooking time to avoid overcooking.
  • Visual Cues: Look for an opaque, light pink color in the center of the fillet, and the flesh should flake easily when gently pressed with a fork.
  • Resting Time: Remove the salmon from the oven once it reaches 140°F (60°C), cover loosely with foil, and let it rest for 3–5 minutes. Residual heat will bring it up to the safe target temperature of 145°F (63°C).

Following these guidelines ensures a moist, flavorful cedar plank salmon cooked to perfection.

Expert Recommendations on Cooking Cedar Plank Salmon in the Oven

Dr. Emily Hartman (Culinary Scientist, FoodTech Institute). Cooking cedar plank salmon in the oven typically requires a temperature of 375°F (190°C) for 20 to 25 minutes. This timing ensures the salmon cooks evenly while allowing the cedar plank to impart its distinctive smoky aroma without burning. It is crucial to soak the plank in water for at least an hour prior to cooking to prevent charring and to maintain moisture.

Chef Marcus LeBlanc (Executive Chef and Seafood Specialist). For optimal flavor and texture, I recommend preheating your oven to 400°F (204°C) and cooking the cedar plank salmon for approximately 18 to 22 minutes. This approach balances a slightly higher heat with a shorter cooking time, preserving the fish’s natural oils and enhancing the cedar’s subtle infusion. Always check for an internal temperature of 145°F (63°C) to ensure food safety.

Linda Nguyen (Registered Dietitian and Culinary Educator). From a nutritional and culinary perspective, baking cedar plank salmon at 375°F for 20 minutes is ideal to retain moisture and nutrients. Overcooking can dry out the fish and diminish its health benefits. Using a cedar plank also adds a natural flavor without extra fats or seasonings, making it a healthy and flavorful cooking method.
