Peel sweet potatoes, cut into bite-sized pieces, and add to a large mixing bowl. Season with salt and pepper.
MAKING THE LEMON BUTTER
Add butter and olive oil to a small saucepan. Simmer over medium heat until the butter has melted. Add lemon juice, lemon zest, and honey. Simmer for one minute on low heat.
Pour the lemon butter over the sweet potatoes. Toss well to make sure the sweet potatoes are evenly coated.
ROASTING
Transfer sweet potatoes onto the baking sheet and roast for 20 minutes. Check for doneness and add additional time if needed.
*Roasting time can vary between ovens. But it will be between 20 and 25 minutes. Set your timer for 20 minutes first and check for doneness. Add additional time if you want the sweet potatoes to be sticky and gooey.
