Heat remaining 2 Tbsp. olive oil in a large nonstick skillet over medium-high. Slice or tear sweet potatoes into 2" pieces; cook, turning, until deeply browned on several sides, 5–7 minutes. Remove from heat and add reserved glaze (it may spatter a bit). Set over medium heat; cook, spooning glaze over, until thick enough to coat a spoon, about 1 minute.
