Arrowroot powder nutrition facts are worth knowing if you cook gluten-free meals, make homemade sauces, or look for clean-label alternatives to cornstarch. Arrowroot powder has become popular in many kitchens, but most people buying it have no idea what is actually in it or how it compares nutritionally to the other starches they use.
This article covers what arrowroot is, what nutrients it contains, how it stacks up against cornstarch, and how to use it properly in everyday cooking.
What Is Arrowroot Powder
Arrowroot powder comes from the root of a tropical plant called Maranta arundinacea. This plant grows in tropical regions including parts of South America, the Caribbean, and Southeast Asia. The roots are harvested, washed, dried, and ground into a very fine white powder.
It has been used as a food ingredient for hundreds of years. People traditionally used it as an easy-to-digest starch for babies, elderly people, and anyone recovering from illness. Today it is mainly used in cooking as a thickening agent for sauces, soups, gravies, and desserts. The powder is almost completely tasteless and colorless when dissolved in liquid, which makes it a useful thickener that does not change the flavor of your food.
Arrowroot Powder Nutrition Facts Per 100 Grams
Here are the complete arrowroot powder nutrition facts for 100 grams of the powder:
- Calories: 357
- Carbohydrates: 88 grams
- Sugar: 0 grams
- Fiber: 3.4 grams
- Protein: 0.3 grams
- Fat: 0.1 grams
- Sodium: 26 milligrams
- Potassium: 11 milligrams
- Iron: 0.33 milligrams
- Calcium: 40 milligrams
- Phosphorus: 98 milligrams
- Folate: 4 micrograms
The most important thing to notice is that arrowroot powder is almost entirely starch, which means carbohydrates. It has very little protein, almost no fat, and few vitamins or minerals. Its main role is as a source of digestible starch that thickens food. You do not eat arrowroot for its nutrients. You use it for what it does in a recipe.
Arrowroot vs Cornstarch: A Simple Comparison
Many people want to know how arrowroot compares to cornstarch since both are used for thickening. One tablespoon of arrowroot powder has about 29 calories, 7 grams of carbohydrates, 0 grams of fat, 0 grams of protein, and no gluten. One tablespoon of cornstarch has about 30 calories, 7 grams of carbohydrates, 0 grams of fat, 0 grams of protein, and no gluten.
The calorie and carbohydrate numbers are almost identical. The differences come down to how each one behaves in cooking and how the body processes them.
Arrowroot has a slightly lower glycemic index than cornstarch, which means it may cause a slightly gentler rise in blood sugar. It also produces a clearer, glossier gel when used to thicken sauces, while cornstarch can leave a slightly cloudy texture if overcooked. Arrowroot also works better in acidic dishes and holds up better when frozen and thawed compared to cornstarch.
Is Arrowroot Powder Gluten Free
Yes, arrowroot powder is naturally gluten free. It comes from a plant root, not from any grain that contains gluten. This makes it a popular choice for people with celiac disease or gluten sensitivity.
If you need to be strictly gluten free, always check the label to confirm the product was not processed in a facility that also handles wheat or other gluten-containing grains. Cross-contamination can happen in shared facilities.
How to Use Arrowroot Powder in Cooking
To thicken a sauce or gravy, mix arrowroot powder with a small amount of cold water first to make a slurry, then stir that into your hot liquid. Use about one tablespoon of arrowroot per cup of liquid. It thickens quickly, so add it toward the end of cooking and remove from heat once the sauce reaches the right consistency. Cooking arrowroot too long at high heat breaks down the starch and makes the sauce thin again.
In baking, arrowroot can add lightness to cakes and cookies. It is often used alongside other gluten-free flours to improve texture. You can also use it as a binding agent in grain-free recipes.
Who Benefits Most From Using Arrowroot
Arrowroot powder works well for anyone eating gluten free, following a paleo diet, or cooking for someone with a sensitive digestive system. It is a single-ingredient, minimally processed product, which makes it a clean-label option that fits well into natural cooking approaches.
Understanding arrowroot powder nutrition facts helps you use it confidently in your kitchen. Just as knowing what is in your salt choices makes you a smarter cook, knowing what your thickening agents contain gives you a clearer picture of your food.

Can You Use Arrowroot in Hot and Cold Dishes
Arrowroot works well in dishes that are heated and then served warm. It thickens sauces, gravies, and pie fillings beautifully when used correctly. One thing to keep in mind is that arrowroot-thickened sauces do not hold up as well as cornstarch-thickened sauces when reheated multiple times. Each reheating can cause the thickening to break down slightly, making the sauce thinner than it was originally.
For cold dishes or no-cook applications like raw puddings or chilled desserts, arrowroot powder can be used but needs to be cooked first to activate its thickening properties. You cannot simply stir raw arrowroot into a cold mixture and expect it to gel the way gelatin or agar would. It must be dissolved in cold liquid first and then briefly heated to activate.
Arrowroot as a Baby Food Ingredient
One of the traditional uses of arrowroot that is still relevant today is in food for babies and young children. Because arrowroot is very easily digested and has a mild flavor, it has historically been used in teething biscuits and simple puddings for infants. It is gentle on sensitive digestive systems and does not cause the bloating that some other starches can.
If you are making homemade baby food and want to add a little thickness to a fruit or vegetable puree, a small amount of arrowroot powder dissolved in water and stirred in while cooking works well. Always check with your pediatrician before introducing any new starchy ingredient to an infant’s diet.
Storing Arrowroot Powder
Arrowroot powder should be stored in a cool, dry place in an airtight container. Like other fine powders, it can absorb moisture from the air and clump together over time if left open. Stored correctly in a sealed jar in a pantry or cupboard, arrowroot powder stays fresh and effective for about two to three years.
If your arrowroot powder has clumped, break it up with a fork or pass it through a fine sieve before using it in a recipe. Clumped powder can create lumps in your sauce if not properly broken up before adding to hot liquid.
Final Thoughts
The arrowroot powder nutrition facts tell a simple story. It is mostly starch with very few other nutrients. But what makes it valuable in the kitchen is not its vitamin content. It is naturally gluten free, easy to digest, tasteless, and very versatile.
It thickens sauces beautifully, holds up in acidic dishes, freezes well, and has a gentler blood sugar impact than some other starches. If you have been using cornstarch and want a clean, simple alternative, arrowroot is a very practical choice for your kitchen.
