For best results, choose beets that are similar in size to ensure even cooking. To save time, you can roast the beets instead of steaming them. Wrap them individually in foil and bake at 400°F (200°C) until tender. The cooked beets can be stored in an airtight container in the refrigerator for up to 3 days. Experiment with different types of cheese, such as feta or ricotta, for a variation in flavor. Add a sprinkle of toasted nuts, such as walnuts or pistachios, for added texture and flavor.
