Cooking Tips and Best Practices

Now that you know the best gluten-free grains for soups, let’s explore how to cook them perfectly. Each grain behaves differently when boiled in broth, so using the right techniques can make all the difference. Here are the best practices to ensure your soups are flavorful, well-textured, and packed with nutrition.

Selecting the Right Gluten-Free Grains for Your Soup

Choosing the right grain depends on the type of soup you’re making. Some grains absorb liquid and thicken soups, while others retain their shape for a heartier bite.

Soup TypeBest Gluten-Free GrainsTexture
Creamy SoupsAmaranth, teff, milletSmooth, thick
Brothy SoupsRice, sorghum, quinoaLight, fluffy
Hearty StewsBuckwheat, brown rice, sorghumChewy, dense
Vegetable SoupsQuinoa, millet, riceSoft, absorbent
Lentil SoupsTeff, quinoa, buckwheatThick, textured

If you want a thick and creamy texture, choose amaranth or teff, as they release starch while cooking. If you prefer a light, brothy soup, opt for quinoa or rice, which hold their shape well.

Pre-Cooking and Soaking Recommendations

While some gluten-free grains can be added directly to soups, others benefit from pre-soaking or cooking separately.

Pre-soaking helps grains cook faster and evenly. Soak buckwheat, sorghum, and brown rice for at least 4 hours before cooking.
Rinse grains like quinoa, millet, and teff before using. This removes natural skin (such as saponins in quinoa) that can give a bitter taste.
For quick-cooking soups, use pre-cooked or leftover grains to cut down on cooking time. Simply stir them into the soup at the end.

GrainPre-Soaking Needed?Cook Separately?Cooking Time (in Soup)
QuinoaNoNo15–20 min
RiceNo (white), Yes (brown)Optional15–45 min
BuckwheatYesYes20 min
MilletNoOptional10–15 min
AmaranthNoNo20–25 min
SorghumYes (overnight)Yes45–60 min

👉 Rule of thumb: If the grain takes longer than 30 minutes to cook, consider cooking it beforehand separately to avoid cooking too much the rest of your ingredients.
