The Game Plan
-
Let butter soften at room temperature for about 15 minutes. You want it pliable, not melted — think frosting consistency.
-
Mix softened butter with pesto, minced garlic, sun-dried tomatoes, and red pepper flakes (if using) until well combined. This is your compound butter, and it's the backbone of the whole dish.
-
Thaw salmon fillets if frozen — overnight in the fridge is the move, but a sealed bag in a bowl of cold water works in about 30 minutes. Never microwave-thaw salmon unless you enjoy rubbery fish.
-
Pat fillets very dry with paper towels. This matters more than you think. Wet fish steams instead of roasting, and nobody wants steamed Milano.
-
Season fillets generously with salt and pepper on both sides.
-
Place skin-side down on a parchment-lined baking sheet, spacing them a couple inches apart so the heat circulates evenly.
-
Top each fillet with a generous spoonful of the pesto butter mixture, spreading it evenly across the surface. Don't be precious — really pile it on.
-
Bake at 400°F for 15-18 minutes until the salmon flakes easily with a fork and the pesto butter is bubbling and fragrant.
-
Remove from oven, squeeze fresh lemon juice over the top, and garnish with torn basil leaves.
-
Let rest for 2 minutes before serving — this lets the juices settle back into the fish.
-
Serve over rice, mashed potatoes, or with a simple arugula salad. The pesto butter doubles as the dressing.
