Rice flour substitutes
Rice flour is finely milled white or brown rice with virtually no gluten, which gives baked goods a tender, slightly sandy crumb and makes fried coatings exceptionally crisp. It also thickens sauces and gravies without clouding them. Substituting requires matching both the starch behavior and the absence of gluten — swapping in a gluten-heavy flour will produce a noticeably chewier, denser result in most applications.

| Rank | Substitute | Ratio (replaces 1 cup Rice flour) | Notes |
|---|---|---|---|
| #1 | Tapioca starch or tapioca flour | Use 7/8 cup (105 g) tapioca starch for every 1 cup (120 g) rice flour | Closest match in gluten-free baking and thickening; produces a slightly chewier, glossier result than rice flour but behaves similarly in most recipes — widely recommended by King Arthur Baking as a 1:1-ish swap with a small volume reduction. |
| #2 | Potato starch | Use 3/4 cup (100 g) potato starch for every 1 cup (120 g) rice flour | Works well for thickening and as a frying dredge; produces an extra-light, crisp crust. In baked goods it can make texture gummy if overbaked, so watch oven time closely. |
| #3 | Cornstarch | Use 3/4 cup (90 g) cornstarch for every 1 cup (120 g) rice flour when thickening or frying; not recommended as a 1:1 baking swap | Excellent for sauces, gravies, and fried coatings — produces a very crisp crust similar to rice flour. Too dense and starchy to replace rice flour as the primary flour in baked goods; use only for thickening or coating applications. |
| #4 | Oat flour (gluten-free certified) | Use 1 cup (90 g) oat flour for every 1 cup (120 g) rice flour | Works in pancakes, muffins, and quick breads; adds a mild oat flavor and a slightly denser, moister crumb. Not suitable for frying or thickening sauces. Must be certified gluten-free if serving to celiac diners. |
| #5 | Sorghum flour | Use 1 cup (120 g) sorghum flour for every 1 cup (120 g) rice flour | A reliable structural gluten-free flour with a mildly earthy flavor; commonly used in gluten-free flour blends alongside starches. Works better in combination with a starch (like tapioca or potato starch) than as a solo swap — solo use can produce a slightly gritty texture. |
| #6 | All-purpose flour | Use 3/4 cup (90 g) all-purpose flour for every 1 cup (120 g) rice flour | Works in a pinch for thickening and as a frying dredge, but introduces gluten that will make fried coatings puffier and less shatteringly crisp, and will make baked goods noticeably chewier and heavier. Not appropriate for gluten-free recipes. This is a last-resort option — the result is noticeably different. |
When to be careful
Rice flour's specific fine, low-protein starch is essential in traditional East and Southeast Asian recipes — mochi, rice noodles, cheung fun, and Chinese New Year cakes (nian gao) — where no substitute will replicate the characteristic chewy-yet-tender texture. In these applications, using the correct ingredient is the only reliable path.
Why these substitutes work
Rice flour's starch granules are among the smallest of any grain flour, which is why it produces uniquely light, crisp fried coatings and a tender, slightly gritty crumb in baked goods. It contains almost no gluten-forming proteins, so structure in baked goods must come from eggs, xanthan gum, or starch gelatinization rather than gluten networks. The substitutes above work because they are similarly low- or no-gluten starches that gelatinize under heat, though each differs in granule size and amylose-to-amylopectin ratio, which affects the final texture's chewiness and clarity.
Rice flour’s role shifts considerably depending on the application — thickening, frying, or baking — so no single substitute covers all three equally well. For frying and sauce thickening, cornstarch and potato starch are the most consistent swaps and are the ones most experienced cooks reach for first. For gluten-free baking, tapioca starch or a combination of tapioca starch and sorghum flour gets closest to rice flour’s behavior, though expect minor texture differences in fine-crumbed recipes.
The substitute table above is ordered by overall reliability across applications. If a recipe calls for rice flour in a context not listed in a substitute’s notes — particularly traditional Asian sweets, rice noodles, or mochi — treat substitution as high-risk and source the correct ingredient instead.
Frequently asked questions
- Can I substitute all-purpose flour for rice flour in gluten-free baking?
- No. All-purpose flour contains gluten, which fundamentally changes the structure and texture of the baked good, and makes it unsuitable for anyone avoiding gluten. Use a gluten-free alternative such as tapioca starch, potato starch, or oat flour instead.
- Is sweet rice flour (glutinous rice flour) the same as regular rice flour?
- No, and they are not interchangeable. Regular rice flour is milled from long- or medium-grain rice and produces a drier, crumblier texture. Sweet rice flour (also called glutinous rice flour or mochiko) is milled from short-grain glutinous rice and produces a stretchy, chewy texture. Substituting one for the other will significantly change the outcome.
- What is the best rice flour substitute specifically for making crispy fried chicken or tempura?
- Cornstarch or potato starch are the most reliable options for frying. Both produce a very crisp, light crust. Use 3/4 cup (90–100 g) of either per 1 cup rice flour called for in the coating. Potato starch in particular is widely cited by Serious Eats and America's Test Kitchen for producing an exceptionally shatteringly crisp fried coating.
