teaspoons olive oil, divided
pork roast (2½ pounds), tied at 1-inch intervals
Salt and pepper
Gala apples, quartered
sweet potatoes, cut into ½-inch wedges
cups chicken broth
Preheat oven to 475 degrees. Coat a heavy-bottomed metal roasting pan with 2 teaspoons oil. Place pork in center and season with salt and pepper. Roast until top is golden, about 15 minutes. Toss apples and sweet potatoes with remaining 2 teaspoons oil and add to pan, arranging around pork. Return to oven and roast until apples and sweet potatoes are tender and an instant-read thermometer inserted in center of pork reads 140 degrees, about 20 minutes. Remove pork, apples, and sweet potatoes from pan. Allow meat to rest 10 minutes before slicing. To make the sauce, whisk flour into pan drippings over medium heat, then slowly whisk in chicken broth and cook until thickened.
