Generally speaking, to preserve their color and nutrients, beets should never be cut or peeled before cooking them in liquid; otherwise, they will "bleed" their rich red juices while cooking and turn an unappetizing dull brown. Scrub the beets very gently and rinse well, but be careful not to break the skin, which is quite thin. Leave at least 1" of stem and don't trim the root.
Beets are done when you can easily pierce them with the tip of a sharp knife. Once cooked, you can peel them; the skin of a cooked beet will slip right off. (However, it's wise to use a paper towel or wear gloves to keep the beet juice from staining your hands.) Then cut the beet in quarters, slices, cubes, or in long, thin strips--or, if they're small, serve whole.
Cooked beets hold their color better if some acid ingredient is added to the cooking water; vinegar or lemon juice, used in many beet recipes, will keep them a beautiful crimson.
Baking: Dry-heat cooking locks in nutrients and intensifies the natural sweetness of beets. It's not a quick method, though: To save time, cook a large quantity of beets at once, then chill some for later use in salads. You can also bake beets when you're baking or roasting something else. Wrap beets in foil, place them in a baking pan, and bake in a 350°F to 400°F oven until tender. Unwrap and let stand until they're just cool enough to handle, then peel them while still warm. Cooking time: 1 1/2 to 2 hours, depending on size.
You can also slice peeled beets, then layer them with thinly sliced onions or apples in a casserole. Add a little broth or stock to keep them moist and cover tightly, then bake/braise. Cooking time: 30 to 60 minutes.
Boiling: This is the most common way of cooking beets, but some of the color (and nutrients) will be lost in the cooking water. Place beets in a pot of boiling water, cover, and simmer until the beets are just tender. Cooking time: 40 minutes to 2 hours, depending on the size and the age of the beets.
Microwaving: Place one pound of whole beets in a microwavable dish with 1/4 cup of liquid. Cover and cook until tender. Cooking time: 10 minutes.
Steaming: Beets can be cooked in a vegetable steamer over boiling water. Tiny beets can be steam-boiled with their leaves attached in a little water with lemon juice and herbs added. Cooking time: 40 minutes.
