Step 1

Place a rack in the center of your oven and preheat the oven to 400 degrees F. Generously coat a large rimmed baking sheet with nonstick spray. Arrange the salmon fillets in the center of the sheet.

Step 2

In a small bowl with a fork, combine the softened butter, garlic, lemon zest, 2 tablespoons chopped fresh parsley, and 1/4 teaspoon black pepper. Mash to create a paste, then rub on the salmon fillets. If desired, arrange extra lemon slices on top.

Step 3

Place the green beans and tomatoes in a large bowl. Drizzle with olive oil and sprinkle with 1/2 teaspoon kosher salt and the remaining 1/4 teaspoon black pepper. Toss to coat, then arrange around the salmon. Drizzle the lemon juice over the top of the salmon and vegetables.

Step 4

Place the sheet pan in the oven and cook until the fish flakes easily with a fork and reaches an internal temperature of 145 degrees F, about 16 to 20 minutes.* Let rest 3 minutes. Sprinkle with remaining 2 tablespoons parsley, then serve, sprinkled with additional salt and/or pepper to taste.
