1. Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).
2. Cut sweet potatoes into wedges. Arrange them in a pan, making sure they’re not overlapping (you’ll probably need two separate pans).
3. Season with salt and pepper.
4. Whisk the rest of the ingredients in a bowl and pour evenly over the sweet potatoes. Toss together.
5. Bake for 45 minutes, checking and mixing halfway through.
