Oven-Roasted Beets

Why This Oven-Roasted Beets Works

In the hot oven, the beet cubes slowly dry a little on the outside while staying moist inside. As they roast, the edges start to brown and the natural sugars in the beets darken. That browning gives the beets a deeper color and a sweeter taste, while the centers stay soft and tender instead of mushy.

Olive oil coats each piece, so the heat hits them evenly and they don’t stick to the pan. The oil also lets the surface of the beets brown instead of just steaming. Salt and pepper cling to the oiled beets, so every side gets seasoned as they roast.

During roasting, the thyme leaves warm up and their taste spreads over the hot beet pieces. Stirring halfway through exposes new sides to the pan and the heat, so more surfaces brown. By the time they come out of the oven, the beets have a light crust on the outside, a soft middle, and a stronger, sweeter beet taste.

Mistakes To Avoid

Cutting the beets into very different sizes makes them cook unevenly. Smaller pieces shrivel and start to burn at the edges while the big chunks stay firm in the center, so the tray ends up with some pieces too hard and others almost dried out.

Roasting at a much lower temperature than 400°F keeps the beets from caramelizing. Instead of getting browned edges and a slightly sticky surface, they just steam on the tray and come out soft, a bit wet, and dull-looking.

Crowding the baking sheet so the beets sit on top of each other traps moisture. In the oven they release juice, it has nowhere to go, and the beets simmer in it, which stops them from getting those roasted, slightly crisp edges.

Skipping the stir halfway through often leads to one side of the beets getting too dark. The side touching the pan can burn while the top stays pale, so the texture is uneven, with some faces tough and others still a bit firm.
