Maple-Mustard Cedar-Plank Salmon with Sweet Onion Crust

For best results, slice the onion into very thin rounds on a mandoline.


1/4 cup maple syrup
2 tablespoons balsamic vinegar
1 teaspoon kosher or sea salt
1/2 teaspoon freshly ground black pepper
1/2 teaspoon chipotle-pepper powder (or 1/4 teaspoon cayenne pepper)
2 garlic cloves, crushed
3 tablespoons mustard seed (or 1-1/2 tablespoons whole-grain mustard)
3/4 cup olive oil, plus extra for fish
2-1/4 pound salmon fillet, washed and patted dry
2 Vidalia or other sweet onions, thinly sliced
Lemon wedges


Combine seasonings and oil in a bowl and whisk. Pour into a large zip-top plastic bag with salmon and onions; seal, pressing out excess air and coating salmon with marinade. Let salmon marinate in refrigerator at least 30 minutes, or up to 3 hours, turning several times.

Soak a cedar plank in water 1 hour. Set up your grill for indirect heat and preheat to about 375°. Brush salmon with olive oil and set on plank. Arrange onions in a single layer over fish. Set plank in grill away from the heat source, cover, and cook until onions are tender and salmon is just opaque in the center, 20–30 minutes, depending on thickness. Serve on plank, surrounded by lemon wedges.
