Cedar Plank Roasted Salmon

Line a baking sheet with parchment paper. Sprinkle both sides of salmon with rub, about 3/4 teaspoon per piece. Rub seasonings into salmon. Place two pieces of salmon on their side, with the skin back to back, on the prepared baking sheet, and refrigerate, uncovered, for at least 2 hours and up to 12 hours.

Preheat oven to 375 degrees. Meanwhile, prepare an ice-water bath. Bring a medium saucepan of water to a boil; add salt. Add carrots, and cook for 1 minute. With a slotted spoon, transfer carrots to ice-water bath. Place potatoes in a separate small saucepan, and cover with water; bring to a boil. Reduce heat to simmer, and cook until tender, about 10 minutes. With slotted spoon transfer to ice-water bath. When vegetables are cool, drain and reserve.

Transfer the pairs of salmon fillets, with the skin still back to back, onto center of cedar plank. In a medium bowl, combine carrots, potatoes, pepper, and mushrooms. Add 2 teaspoons lemon juice, the oil, 1 teaspoon salt, pepper, parsley, and garlic. Toss to combine. Transfer vegetables to cedar plank, surrounding salmon. Sprinkle with remaining lemon juice.

Transfer plank to oven. Bake salmon for 8 minutes. Remove from oven. Turn fish over, and return to oven. Bake until internal temperature of salmon measures 120 degrees on an instant-read thermometer, an additional 6 to 8 minutes.

Remove from oven. Serve directly on plank, or transfer to plates. Brush with melted butter, if desired. Garnish with lemon slices, and serve immediately.
