The Full Answer
Potatoes in all forms — russet, red, white, Yukon Gold, sweet potatoes, purple potatoes, fingerlings — are 100% naturally gluten-free. They are one of the safest and most versatile staple foods for people with celiac disease.
However, how potatoes are PREPARED matters enormously. French fries cooked in shared fryers with breaded items will be cross-contaminated. Mashed potatoes may be thickened with wheat flour. Potato soups often use flour as a thickener. Scalloped/au gratin potatoes typically contain wheat flour in the sauce.
When eating potatoes at restaurants, ask specifically about preparation methods. At home, simple preparations (baked, boiled, roasted with oil and salt) are always safe.
