Roasting beets intensifies their flavor, brings out their earthy sweetness, and makes their peels as easy to peel off as an oversized sweater. Roasted beets are particularly delicious in beet salads (try one of these Easy Beet Salads if you're looking for ideas).
Start with beets that are firm and feel heavy for their size. If the beets came with their greens still attached as pictured above, cut off the greens, wash them, and reserve them for another use (such as one of these delicious Greens Recipes).
Rinse any dirt or debris from the beets—some beets may need to be scrubbed clean—and put the beets on a large piece of aluminum foil and preheat the oven to 375°F.
Note: Beets are fairly flexible veggies, if you have something else in the oven at anywhere between 325°F and 425°F, beets will happily roast up at that temperature alongside what you're already cooking, it just will take a bit longer at lower temperatures.
