Fennel & Meyer Lemon-Stuffed Salmon

Preheat oven to 400 degrees F. Coat a large rimmed baking sheet with cooking spray.

Heat 2 tablespoons oil in a large skillet over medium-high heat. Add shallots; cook, stirring, until starting to soften, 1 to 2 minutes. Reduce heat to medium and add fennel and 1/4 teaspoon salt; cook, stirring occasionally, until tender and lightly browned, 6 to 8 minutes. Add garlic; cook 1 minute more. Remove from heat and let stand for 5 minutes.

Place fish on the prepared baking sheet. Rub the inside with the remaining 1 tablespoon oil and season with the remaining 1 3/4 teaspoons salt and pepper. Fill the cavity with lemon slices and the fennel mixture.

Roast the fish until it flakes easily with a fork, 30 to 35 minutes. Let stand 10 minutes before serving. Garnish with the reserved fennel fronds and more lemon slices, if desired. Remove the fish from the bones to serve.
