For a deeper flavor, try adding a clove of minced garlic to the beets before roasting. A splash of balsamic vinegar after roasting adds a tangy counterpoint to the sweetness of the beets. Roasting time may vary depending on the size of the beet cubes and your oven. Check for doneness after 25 minutes. Consider adding a sprinkle of toasted pine nuts or crumbled goat cheese for added texture and flavor.
