We're doubling the batch and there's not enough arrowroot powder to cover it. Arrowroot is a neutral thickener that leaves sauces glossy and clear, which matters when you want the dish to look polished.
The right substitute depends on heat level and acidity, not just starch type. Some thickeners break down in prolonged simmering or turn cloudy in acidic mixtures, so matching the cooking method keeps your dish on track.
| # | Substitute | Best For | Ratio | Key Note |
|---|---|---|---|---|
| 1 | Tapioca Starch | ✨ Both | 1:1 | Slightly stickier texture |
| 2 | Cornstarch | ✨ Both | 1:1 | Less glossy finish |
| 3 | Potato Starch | ✨ Both | 1:1 | Light texture, breaks down if overcooked |
| 4 | Rice Flour | ✨ Both | 2:1 | Slightly grainy texture |
| 5 | Wheat Flour | 🍳 Cooking | 2:1 | Nutty flavor, contains gluten |
| 6 | Kuzu Powder | ✨ Both | 1:1 | Subtle sweetness, expensive |
| 7 | Agar Agar | 🥧 Baking | 1 teaspoon per 1 tbsp | Firmer set, vegan gelatin |
Tapioca starch and potato starch are top substitutes, matching arrowroot's neutral flavor and clear finish. Choose based on heat tolerance and desired glossiness. Adjust ratios carefully, and toast wheat flour to avoid raw taste in hearty sauces.

1 - Tapioca Starch
Tapioca starch mimics arrowroot's neutral flavor and creates a glossy finish in sauces and soups. It thickens quickly and works well in both sweet and savory dishes.
The texture turns slightly stickier than arrowroot, especially in cold applications like puddings. Use the same amount and add it at the end of cooking to avoid overdoing the viscosity.
- Mix with cold water first to prevent clumping.
- Avoid stirring too long after it thickens; the sauce can turn stringy.
- Works great in fruit pie fillings and Asian sauces.
- Stays clear even after cooling, so it won't cloud your glaze.
Skip if: you need a completely neutral mouthfeel in chilled desserts.
Tapioca Starch
Works for: clear glazes and quick-thickening sauces
Skip if: you're making a delicate custard that needs zero stickiness
Cornstarch
Works for: baking and crispy coatings
Skip if: your sauce has lemon juice or vinegar
2 - Cornstarch
Cornstarch thickens quickly and handles high heat better than most starches, making it reliable for stir-fries and baked goods. It produces a slightly less glossy finish than arrowroot, so sauces look more opaque.
If your recipe includes acid like lemon juice or tomatoes, cornstarch can break down and thin out. When you're short on cornstarch too, Cornstarch substitutes ranked covers starches that resist breaking down in acidic dishes.
Skip if: you're thickening a tangy fruit compote or marinade with citrus.
3 - Potato Starch
Potato starch delivers a neutral taste and light texture, making it a strong match for gluten-free baking and frying. It thickens sauces fast and stays clear like arrowroot.
Prolonged cooking breaks it down, so add it toward the end. Use the same amount and avoid reheating dishes thickened with potato starch multiple times.
Skip if: your recipe simmers for more than 15 minutes after thickening.
4 - Rice Flour
Rice flour thickens sauces and works in gluten-free baking, though it needs double the amount of arrowroot. The texture runs slightly grainy, so it's better in dishes where a smooth, glossy finish isn't critical.
Use 2 tablespoons of rice flour for every 1 tablespoon of arrowroot. When you're missing rice flour as well, replacements similar to Rice Flour ranks grain-based options that thicken without gluten.
Here's what to know:
- Mix with cold liquid before adding to hot dishes to avoid lumps.
- Works well in hearty gravies and stews where a bit of texture is acceptable.
Skip if: you're making a delicate sauce that needs to stay perfectly smooth.
| Use | Ratio | Notes |
|---|---|---|
| Clear sauces | 1:1 tapioca starch | Stays glossy, slightly sticky |
| Baking | 1:1 cornstarch | Less shine, handles oven heat |
| Gravies | 2:1 wheat flour | Heavier body, nutty flavor |
5 - Wheat Flour
Wheat flour thickens hearty sauces and gravies with a slightly nutty flavor and heavier body than arrowroot. It needs double the amount and works best when you toast it in butter first to remove the raw flour taste.
Use 2 tablespoons of wheat flour for every 1 tablespoon of arrowroot. Out of wheat flour as well?
Replacements similar to Whole Wheat Flour covers grain-based thickeners that handle longer cook times.
Skip if: you need a gluten-free option or want a clear, glossy finish.
6 - Kuzu Powder (Kudzu)
Kuzu powder creates clear, glossy sauces and jellies with a texture nearly identical to arrowroot. It carries a subtle earthy sweetness that works well in desserts and Asian-inspired dishes.
Use the same amount as arrowroot. Kuzu dissolves more slowly, so stir it into cold water first and let the mixture sit for a minute before adding it to your dish.
- Takes slightly longer to thicken than arrowroot, so give it an extra minute on the heat.
- Stays stable in acidic mixtures, making it reliable for fruit glazes.
- Often sold in chunks that need crushing before use.
- More expensive than most starches, so save it for recipes where clarity matters.
Skip if: you need a thickener that works instantly or you're on a tight budget.
7 - Agar Agar Powder
Agar agar sets firmly and works as a plant-based gelatin replacement, not a direct thickener. It creates a firmer texture than arrowroot, so it's best for jellies, panna cotta, or vegan desserts that need structure.
Use 1 teaspoon of agar agar for every tablespoon of arrowroot. Dissolve it in liquid and bring it to a boil for 1-2 minutes to activate the gelling agent.
- Sets at room temperature, unlike arrowroot which thickens without gelling.
- Won't work in quick-thickening sauces or gravies that need to stay pourable.
Missing agar agar as well? Quick Agar Agar replacements to try ranks gelling agents that give you similar firmness for vegan desserts.
Skip if: you're thickening a sauce that needs to stay fluid.
Making Arrowroot Powder Substitutes Work
Most of these swaps work without changing the recipe, but the best choice depends on what you're making. For clear sauces and glazes, tapioca starch or kuzu powder come closest.
For baking or crispy coatings, cornstarch handles high heat better.
- Closest match - Tapioca starch: neutral flavor, glossy finish
- Easiest grab - Cornstarch: widely available, reliable for most uses
- Dietary option - Potato starch: gluten-free, light texture
Frequently Asked Questions
Yes, use a 1:1 ratio for cornstarch in most recipes. It thickens similarly but produces a less glossy finish and can break down in acidic dishes, so avoid it in sauces with citrus or vinegar.
Tapioca starch has a neutral flavor just like arrowroot, so the taste won't change. The main difference is a slightly stickier texture, especially in cold dishes like puddings.
Cornstarch or potato starch work best in baking. Both handle oven heat well and won't alter the texture of cakes, cookies, or pie fillings.
No, wheat flour contains gluten. Stick to tapioca starch, potato starch, or rice flour for gluten-free thickening.
Cornstarch creates a more opaque finish than arrowroot. If you need a clear, glossy sauce, switch to tapioca starch or kuzu powder instead.
