Difference Between Broth and Bouillon
Broth is a liquid made by simmering meat (often with vegetables) in water. Bouillon is concentrated, dehydrated broth sold as cubes, powder, or paste—add water to reconstitute. Stock uses bones (not just meat) and is typically unseasoned. All three provide savory flavor for soups and sauces, but they have different intensities and salt levels.
Key Takeaways
Explanation
Traditional broth is made by simmering meat with aromatics. It's flavorful on its own and typically seasoned. Stock uses bones (roasted for more flavor), which contribute gelatin that gives body. Stock is usually left unseasoned as a cooking ingredient. In practice, store-bought "broth" and "stock" are often used interchangeably.
Bouillon is broth that's been concentrated and dehydrated for long shelf life. Cubes, powders, and paste forms exist. It's convenient and compact but typically very high in sodium and may contain additives for flavor enhancement. One cube dissolved in water makes about one cup of broth.
For recipes, homemade stock has the best flavor and body. Store-bought broth is convenient and good quality. Bouillon is emergency pantry backup—it provides savory flavor but can taste artificial and is very salty. Low-sodium versions of all types exist.
The sodium content varies dramatically between these products. A cup of homemade broth typically contains 200-400 mg of sodium (depending on how much salt you add). Store-bought broth averages 800-900 mg per cup, while reconstituted bouillon can hit 900-1,200 mg per cup. Low-sodium versions cut these numbers roughly in half. For reference, the American Heart Association recommends no more than 2,300 mg of sodium per day, so a single cup of regular bouillon can represent over half that limit.
Gelatin is the key difference between a good stock and ordinary broth. Bones contain collagen, which converts to gelatin after 4-6 hours of simmering (8-12 hours for beef bones). Properly made stock sets into a jiggle when refrigerated, similar to Jello. This gelatin gives sauces their silky body and soups their rich mouthfeel. Broth made only from meat will never gel because muscle tissue contains minimal collagen. This is why French cuisine prizes stock as a foundation and why demi-glace (reduced stock) is considered essential to classical saucemaking.
Things to Know
- "Better Than Bouillon" paste is popular—it's concentrated broth that refrigerates after opening.
- Bone broth is essentially long-simmered stock marketed for its gelatin and collagen.
- Vegetable "broth" uses no meat but the term is applied loosely.
- You can strengthen weak broth by simmering with extra aromatics or a bouillon cube.
- Dashi, the Japanese stock made from kombu seaweed and bonito flakes, achieves deep umami flavor in just 10-15 minutes, unlike Western stocks that require hours of simmering.
