Sage and browned butter is a classic pairing that enhances roasted turnips (which look like white, oversized radishes). Toss with the butter mixture as soon as the turnips are done.
Preheat oven to 400°F.
Place turnips on a baking sheet coated with cooking spray; sprinkle with salt and pepper. Bake at 400°F for 50 minutes or until tender and lightly browned, stirring once after 30 minutes.
Combine butter and 6 sage leaves in a small saucepan over medium; cook 3 minutes or until butter is lightly browned and fragrant. Remove pan from heat; stir in 1 teaspoon rind and juice. Combine turnips and butter mixture in a bowl; toss to coat. Arrange turnip mixture on a platter; sprinkle with remaining 6 sage leaves and remaining 1 teaspoon rind.
