Do I need to peel beets before roasting?
Nope, not always. If you roast whole beets (especially in foil), you can leave the skin on and rub it off with paper towels once they are fully tender. If you are doing sheet pan wedges for caramelized edges, either leave the skins on (they are edible) or peel first if you want the cleanest look and easiest eating.
Foil-wrapped or open-pan roasting, which is better?
Foil-wrapped is best for whole beets: super tender, evenly cooked, and the paper-towel peeling trick works like a charm. Open-pan (sheet pan) is best for wedges: more caramelization and slightly crisp edges. If I am serving them as a stand-alone side, I go sheet pan. If I am meal prepping for salads, foil is my best friend.
Why are my roasted beets still hard?
Usually they are either too large (cut smaller), too crowded (spread out), or they simply need more time. Beets can be stubborn. Roast until a knife slides into the thickest part with almost no resistance.
How do I keep beet stains under control?
Wear gloves if you want, but my go-to is this: line your board with parchment, use a dark towel you do not love, and peel whole beets by rubbing with paper towels after roasting. Quick note: parchment helps a lot, but porous wood boards and some counters can still stain, so wipe up fast and do not let beet juice linger.
Can I roast different colored beets together?
You can, but red beets will tint everything. If you want the golden or candy-striped beets to stay bright, roast them in separate foil packets.
Can I make these ahead?
Yes. Roast the beets ahead, then toss with lemon, vinegar, and herbs right before serving so the flavor stays bright and punchy.
