Crispy Gluten-Free Roasted Potatoes Recipe

Potatoes themselves contain no gluten, they're a starchy vegetable, not a grain, so this recipe leans into that by keeping the ingredient list short: just potatoes, oil, garlic, and herbs, with no flour-based coatings or premade seasoning blends that could introduce cross-contact for anyone avoiding gluten.

Instructions

  1. 1Preheat the oven to 425°F (220°C) and line a rimmed baking sheet with parchment paper.
  2. 2Halve or quarter the potatoes so all the pieces are roughly the same size, about 1 to 1.5 inches, so they finish cooking at the same time.
  3. 3In a large bowl, toss the potatoes with olive oil, minced garlic, rosemary, thyme, salt, and pepper until evenly coated.
  4. 4Spread the potatoes in a single layer on the baking sheet, cut side down, leaving space between pieces.
  5. 5Roast for 20 minutes, then flip each piece and roast for another 15 to 20 minutes, until deeply golden and easily pierced with a fork.
  6. 6Remove from the oven and toss with grated Parmesan, if using, while still hot. Serve immediately.

Tips & variations

  • Check any store-bought seasoning blend labels before using them here; some pre-mixed spice blends use wheat starch as an anti-caking agent, while single-ingredient dried herbs and plain salt and pepper are always safe.
  • Swap Yukon Golds for red potatoes or fingerlings, both hold their shape well when roasted and don't need peeling.
  • Add a squeeze of lemon juice or a spoonful of grated Parmesan right after roasting for extra brightness without adding any flour-based thickener.

Storage & reheating

Store leftover potatoes in an airtight container in the refrigerator for up to 4 days. Reheat in a 400°F (200°C) oven or air fryer for 8 to 10 minutes to restore crispness; microwaving will soften the crust.

Tips from the Tulo kitchen

  • Dry the potatoes thoroughly with a towel after washing, excess surface moisture is the main reason roasted potatoes steam instead of crisp.
  • A dark, heavy baking sheet browns potatoes more evenly than a light-colored one, since it absorbs and holds more heat.

FAQ

Do potatoes have gluten?

No. Potatoes are a starchy vegetable, not a grain, and contain no gluten in their natural form. Gluten only comes from wheat, barley, rye, and their derivatives.

Why do some potato products contain gluten then?

Cross-contact and added ingredients are the usual causes: frozen fries and hash browns are sometimes coated in a wheat-based batter for crispness, and some seasoned or flavored potato chips use malt vinegar powder or wheat-derived starches in the seasoning.

Are french fries always gluten-free?

Not necessarily. Restaurant fries are often fried in the same oil used for breaded items like chicken tenders or onion rings, which introduces cross-contact even if the potatoes themselves are gluten-free.

Is potato starch gluten-free?

Yes. Potato starch is extracted purely from the potato and contains no gluten, which is why it's commonly used as a thickener in gluten-free baking.
