Trout with Almond-Parsley Butter

Cook oil and garlic in a large pot over medium heat until garlic begins to sizzle, about 1 minute. Add spinach, season with salt, cover, and cook, stirring once, until just wilted, about 2 minutes. Drain excess liquid and set aside. Meanwhile, in a small bowl, combine 3 tablespoons butter, almonds, lemon zest, and parsley. Season with salt and pepper and set aside.

Set broiler to high, with a rack in top position. Melt remaining 1 tablespoon butter and brush onto flesh sides of fish. Season with salt and pepper. Lightly dust buttered sides of fish with flour, tapping off excess.

Brush a rimmed baking sheet with oil; arrange fish flesh-side up and broil until just cooked through, about 5 minutes. Using two spatulas, transfer to plates. Dollop with almond butter and serve with spinach and lemon wedges.
