Beet skin is not only safe to eat, it’s more nutritious than the flesh inside. The peel contains roughly three times the concentration of betalains (the pigments responsible for that deep red-purple color) compared to the inner root, along with nearly three times the phenolic compounds that act as antioxidants. Leaving the skin on is one of the easiest ways to get more out of every beet you eat.
Why the Skin Is More Nutrient-Dense
The outer layer of a beet is where the plant concentrates many of its protective compounds. Lab analyses of beet peel versus flesh show striking differences. The peel contains about 7.2 mg of total betalains per gram of dry weight, compared to 2.6 mg in the flesh. That’s not a small gap. The same pattern holds for total phenolic compounds: 3.9 mg per gram in the peel versus 1.35 mg in the flesh.
Betalains are the pigments that give beets their color, and they double as powerful antioxidants. Beet peel extract has demonstrated antioxidant inhibition rates above 90% in lab assays, meaning it neutralizes the vast majority of free radicals it encounters. These compounds have been linked to reduced inflammation and may support cardiovascular health, which is part of why beets in general have such a strong nutritional reputation.
The skin also contributes extra fiber. Beet peels contain about 2.6 grams of crude fiber per 100 grams, while the juice from the inner flesh registers essentially no detectable fiber. If you peel your beets before eating, you’re discarding a meaningful portion of that roughage.
Every Part of the Beet Is Edible
There’s nothing toxic or harmful about beet skin for most people. The entire plant, from stems to leaves to the outer layer of the root, is edible. The main thing to do before cooking or eating beets with the skin on is wash them thoroughly to remove any soil or residue. A good scrub under running water with a vegetable brush is sufficient for most home cooks.
Pesticide residues on root vegetables like beets tend to fall below maximum residue limits when tested under normal growing conditions. Still, scrubbing is a smart habit, and choosing organic beets removes that concern entirely if it matters to you.
One Thing to Watch: Oxalates
Beets contain oxalates, compounds that can raise uric acid levels and contribute to kidney stone formation in susceptible people. This isn’t unique to the skin; the entire beet contains them, and beet greens (the leafy tops) contain even higher levels, with soluble oxalate concentrations reaching over 7,000 mg per 100 grams of dry matter in regrowth leaves.
If you have a history of kidney stones or gout, keeping your beet intake to about a half-cup serving per day is a reasonable guideline. For everyone else, the oxalate content in a normal portion of beets, skin included, isn’t a concern. Cooking beets with dairy (milk or cream) can also reduce soluble oxalate levels, since calcium binds to the oxalates and makes them less absorbable.
Best Ways to Eat Beet Skin
The cooking method you choose affects both the texture of the skin and how many nutrients survive. Roasting is one of the best options. Coat whole beets in olive oil and a pinch of salt, wrap them tightly in foil, and roast at about 180°C (356°F) until a knife slides through easily. The salt helps soften the skin, and the enclosed foil steams the beet from the inside, making the peel tender enough to eat without any chewiness. Smaller or similarly sized beets roast faster and more evenly.
If you want to keep the skin on, simply eat the roasted beet whole. If you prefer to remove it, the skin slips off easily while the beet is still hot. Use a towel you don’t mind staining, because hot beet juice will dye fabric and fingers alike.
Beyond roasting, beet skin holds up well in other preparations. Thinly sliced raw beets with skin intact work in salads and slaws. Pickled beets are traditionally prepared with the skin on, and the vinegar brine softens it over time. Steaming and boiling also work, though boiling in plain water can leach some water-soluble nutrients like betalains into the cooking liquid. If you boil beets, using that liquid in soups or sauces recaptures what would otherwise be lost.
Should You Always Leave the Skin On?
For nutrition, yes. Peeling beets before eating them removes the most antioxidant-rich part of the vegetable. You lose about two-thirds of the betalain content and a significant share of the fiber and phenolic compounds. It’s the same principle as eating potato skins or apple peels: the outer layer is doing more nutritional work per gram than the inside.
The only practical reason to peel is texture preference. Raw beet skin can be slightly tough, and some people find it unpleasant in certain dishes. If that’s the case, roasting until very tender or slicing the beets thin enough that the skin isn’t noticeable are both easy workarounds. For smoothies and juiced beets, tossing in the whole unpeeled beet is the simplest approach and adds a richer color along with the extra nutrients.
