Maple-Mustard Sheet-Pan Salmon

Steps

1. Preheat oven to 375°F with a rack in the upper third.
2. Toss radishes and potatoes with olive oil, salt, and pepper on a large rimmed baking sheet until evenly coated. Arrange in a single layer.
3. Roast until potatoes are fork-tender and starting to brown, 45-55 minutes.
4. Meanwhile, whisk together Dijon mustard, maple syrup, garlic powder, a pinch of salt, and a pinch of pepper in a small bowl.
5. Season both sides of the salmon fillet with salt and pepper.
6. Push the roasted vegetables to the sides of the baking sheet and place salmon in the center.
7. Set aside half of the mustard mixture in a separate bowl. Brush the remaining mustard mixture over the salmon.
8. Bake until salmon is almost cooked through and opaque, 15-17 minutes.
9. Heat the broiler. Broil salmon and vegetables until salmon is deeply browned in spots, 3-8 minutes, watching closely to avoid burning.
10. Whisk lemon juice into the reserved mustard mixture and drizzle evenly over the salmon and vegetables.
11. Top with dill sprigs and serve with lemon wedges, if desired.
