Amaranth is a grain with more protein and minerals than wheat or rice

Amaranth is a small seed that cooks into a porridge-like grain and contains roughly 13 to 14 grams of protein per cooked cup—about twice what you get from the same amount of cooked rice. It also delivers significant amounts of manganese, magnesium, phosphorus, and iron, plus fiber that most refined grains lack. Unlike wheat, amaranth is naturally gluten-free, which matters if you have celiac disease or gluten sensitivity.

The grain has been cultivated for thousands of years in Central and South America and is now grown commercially in the United States, India, and Peru. You can buy it as whole seeds, flour, or puffed (like cereal). The whole seed is the most versatile form and keeps longer than flour.

Amaranth won't transform your health on its own, but it works well as a regular part of a varied diet—especially if you're looking to add plant-based protein or need to avoid gluten. The trade-off is texture: it's starchy and can feel gluey if you don't cook it with enough liquid, and it has a mild, slightly earthy taste that doesn't appeal to everyone on first try.

Key Takeaways

  • Amaranth contains nearly twice the protein of rice and is naturally gluten-free, making it useful for plant-based eating or gluten avoidance.
  • Cook whole amaranth seeds with a 3-to-1 water ratio for about 20 minutes to get a creamy porridge texture, or use less water for a fluffier grain side dish.
  • Amaranth flour works in baking but absorbs more liquid than wheat flour, so you'll need to adjust recipes or mix it with other flours.
  • The grain is high in oxalates, which may be a concern if you have a history of kidney stones or are advised to limit oxalate intake.
  • Puffed amaranth makes a quick breakfast cereal or snack but contains less fiber than whole seeds and often has added sugar.

How to cook whole amaranth seeds

Rinse the seeds under cold water first—this removes dust and any debris. Use a 3-to-1 ratio of water to amaranth (so 1 cup water to 1/3 cup seeds). Bring the water to a boil, add the seeds, then reduce heat to low and cover. Simmer for 15 to 20 minutes until the water is absorbed and the seeds have a soft, slightly translucent look. The result will be creamy and porridge-like.

If you prefer a fluffier texture closer to rice, use a 2-to-1 water ratio instead and cook for the same time. Stir occasionally to prevent sticking on the bottom. Once cooked, amaranth can be eaten warm as a breakfast porridge with fruit and nuts, or cooled and used in salads, grain bowls, or as a side dish. It keeps in the refrigerator for up to five days in an airtight container.

One batch of 1/3 cup dry seeds yields about 1 cup cooked amaranth, which is roughly two servings. A single serving of cooked amaranth contains about 4 grams of protein and 3 grams of fiber, along with meaningful amounts of manganese and magnesium.

Using amaranth flour in baking and cooking

Amaranth flour is finer than whole seeds and works in pancakes, muffins, flatbreads, and porridges. Because it absorbs more liquid than wheat flour and lacks gluten, it doesn't hold together the same way. Most bakers replace no more than 25 to 30 percent of wheat flour with amaranth flour in a recipe, or mix it with other gluten-free flours like rice flour or tapioca starch to improve texture.

If you're baking with 100 percent amaranth flour, expect a denser crumb and a slightly nutty, earthy flavor. Pancakes and quick breads work better than yeast breads, since amaranth flour won't develop the structure yeast breads need. Start by substituting 1/4 cup of amaranth flour for every 1 cup of wheat flour in a recipe, then adjust based on how the batter looks—it should be slightly thicker than usual.

Amaranth flour also thickens soups and stews and can be mixed into smoothies for added protein and nutrients. Store flour in an airtight container in a cool, dark place or in the refrigerator, since the small particle size means it can go rancid faster than whole seeds.

Puffed amaranth as a breakfast cereal and snack

Puffed amaranth is whole seeds that have been heated until they pop, similar to popcorn. It's ready to eat straight from the package and requires no cooking. You can eat it dry as a crunchy snack, mix it into yogurt, or pour milk over it like cereal. One serving (about 1 ounce or a small handful) contains roughly 3 to 4 grams of protein.

The downside is that puffing removes some of the fiber present in whole seeds, and many commercial brands add sugar or honey. Check the ingredient list—some puffed amaranth products contain 5 to 8 grams of added sugar per serving. Plain, unsweetened puffed amaranth exists but is less common in regular grocery stores; health food stores and online retailers are more reliable sources.

Puffed amaranth also goes stale quickly once opened, so buy smaller packages or transfer it to an airtight container. It keeps for about two weeks after opening if stored in a cool, dry place.

Nutritional content and what it means for your diet

One cup of cooked amaranth (about 250 grams) contains roughly 250 calories, 9 grams of protein, 46 grams of carbohydrates, 5 grams of fiber, and 5 grams of fat. It's a good source of manganese (about 105 percent of the daily value), magnesium (about 38 percent), phosphorus (about 28 percent), and iron (about 29 percent for men, higher for women depending on age). These minerals matter for bone health, energy production, and oxygen transport in the blood.

Amaranth is also one of the few plant foods that contains all nine essential amino acids—the building blocks your body can't make on its own. This makes it a complete protein, which is useful if you eat little or no meat, though the total protein per serving is still modest compared to eggs or chicken. Combining amaranth with legumes (beans, lentils) or nuts creates a more substantial protein meal.

The grain is high in oxalates, compounds that bind to calcium and may increase kidney stone risk in people with a personal or family history of stones. If you've had kidney stones or your doctor has advised you to limit oxalates, eat amaranth in moderation or discuss it with your healthcare provider first.

Where to buy amaranth and how to store it

Whole amaranth seeds are available in most grocery stores in the bulk bins or packaged grain section, often near quinoa or millet. Health food stores, natural markets, and online retailers (including Amazon, Vitacost, and Bob's Red Mill's website) carry amaranth seeds, flour, and puffed varieties. Prices vary—bulk bins are usually cheaper per pound than packaged options. Expect to pay roughly $1 to $3 per pound for whole seeds, depending on where you shop and whether you buy organic.

Store whole seeds in an airtight container in a cool, dry cupboard for up to one year, or in the refrigerator or freezer for longer shelf life. Amaranth flour should be stored in an airtight container in the refrigerator or freezer if you don't plan to use it within a month, since the fine particles can oxidize and go rancid. Puffed amaranth keeps for about two weeks in an airtight container at room temperature.

If you can't find amaranth locally, online ordering is straightforward—most retailers ship within a week. Organic amaranth costs more but may matter if you prefer to avoid pesticide residues; conventional amaranth is also widely available and less expensive.

straightforward recipes to get your free guide

The easiest entry point is amaranth porridge: cook 1/3 cup seeds with 1 cup water for 20 minutes, then stir in a pinch of salt, cinnamon, and a splash of milk or plant-based alternative. Top with sliced banana, berries, nuts, or a drizzle of honey. This takes about 25 minutes total and makes two servings.

For a savory side dish, cook amaranth with vegetable or chicken broth instead of water, then fluff with a fork and mix in roasted vegetables, herbs, and a squeeze of lemon juice. Amaranth also works in grain bowls alongside roasted chickpeas, greens, and tahini dressing, or mixed into soups in the last few minutes of cooking to add body and nutrition.

If you want to try amaranth flour without committing to a full recipe, mix 2 tablespoons into your regular pancake batter and cook as usual. You'll notice a slightly denser texture and nuttier flavor without having to rewrite the whole recipe. Once you're comfortable with the taste and texture, you can experiment with higher ratios or dedicated amaranth recipes.

Frequently Asked Questions

Does amaranth taste good, or does it have a strong flavor?

Amaranth has a mild, slightly earthy, and faintly nutty taste—not strong or unpleasant, but noticeable. Most people find it neutral enough to pair with sweet toppings (fruit, honey, cinnamon) or savory ones (broth, vegetables, herbs). If you dislike the taste on first try, mixing it with rice or another grain you enjoy can make it more palatable.

Can I pop amaranth like popcorn at home?

Yes. Heat a dry skillet over medium-high heat, add a small handful of amaranth seeds, and stir constantly for 2 to 3 minutes until they pop and turn light brown. They pop quickly and can burn, so watch carefully. Homemade puffed amaranth is fresher than store-bought and has no added sugar, though it requires more attention than cooking whole seeds.

Is amaranth safe if I have celiac disease?

Yes. Amaranth is naturally gluten-free and safe for people with celiac disease. However, check the package label for a certified gluten-free symbol, since some amaranth products may be processed in facilities that also handle wheat or other gluten-containing grains.

How much amaranth should I eat per day?

There's no set daily amount. Treat amaranth like any other grain—a serving is roughly 1/3 to 1/2 cup cooked, which you can eat once or twice a day as part of a varied diet. If you're new to amaranth or have digestive sensitivity, start with smaller amounts and increase gradually, since the fiber content can cause bloating if you add too much too quickly.

Can I cook amaranth in a rice cooker?

Yes. Use a 3-to-1 water-to-seed ratio and cook on the regular cycle. It should finish in about 20 to 25 minutes. Some rice cookers have a "porridge" setting that works well for amaranth, since the grain benefits from a slightly longer, gentler cook than white rice.
