1. Preheat oven to 475 degrees. Line a large rimmed baking sheet with parchment paper; set aside.

2. In a large bowl, toss together turnips and pears with oil and salt until well combined. Place in an even layer on prepared baking sheet. Transfer to oven and roast, turning with a spatula once or twice during cooking, until browned and turnips are easily pierced with a paring knife, 25 to 30 minutes, rotating baking sheets halfway through baking.

3. Meanwhile, melt butter in a small saucepan over medium heat. Add honey and rosemary; let simmer for a few seconds and remove from heat.

4. Transfer turnips and pears to a large bowl and drizzle with butter mixture; toss to combine. Serve.
