Bouillon Cube to Broth Dilution Calculator
Calculate water needed for bouillon cubes or paste. Standard cube (4-5g) = 1 cup broth. 5 brands compared with sodium content per cup.

Reduce Added Salt When Using Bouillon
A standard bouillon cube provides 950-1300 mg of sodium per cup of broth — far above the 300-500 mg in typical homemade stock. Always taste before adding any additional salt to a dish made with bouillon. For rice or pasta cooked in bouillon broth, you may need no additional salt at all. Low-sodium cubes (350-500 mg/cup) are a practical compromise for people monitoring sodium intake.
Bouillon Sodium Comparison per Cup of Broth
| Type | Standard Dilution | Sodium / Cup | Notes |
|---|---|---|---|
| Knorr 4g cube | 1 cube : 1 cup | ~1100 mg | Most common worldwide |
| Maggi 5g cube | 1 cube : 1 cup | ~950 mg | Popular in Europe, Africa |
| Better Than Bouillon 1 tsp | 1 tsp : 1 cup | ~700 mg | Paste; richer flavor |
| Low-sodium cube | 1 cube : 1 cup | 350-500 mg | Heart-healthy option |
| Homemade stock | n/a | 100-300 mg | Full control over sodium |
Standard Cube-to-Broth Ratios
Different bouillon brands and forms produce different broth strengths from the same volume of water. Use this calculator to convert between cubes and finished broth volume.
| Brand/Form | Weight | Water per unit | Sodium per cup |
|---|---|---|---|
| Knorr cube | 4g | 1 cup (240ml) | 1100mg |
| Maggi cube | 5g | 1 cup (240ml) | 950mg |
| Costco bulk | 9g | 1.5-2 cups | 1500mg |
| Large cube | 10g | 2 cups (480ml) | 1700mg |
| Better Than Bouillon paste | 1 tsp (6g) | 1 cup (240ml) | 700mg |
| Low-sodium cube | 5g | 1 cup (240ml) | 400mg |
Adjusting Strength: Light, Standard, Concentrated
The standard cube-to-water ratio (1 cube per cup) produces broth at the strength manufacturers intend — full-flavored but heavily salted. Adjust based on use:
- Light (1 cube per 1.5 cups water): For sipping, delicate consommé, or as a base for clear soups where you'll add other flavorful ingredients (mushrooms, ginger, soy sauce). Reduces sodium per cup by 33%.
- Standard (1 cube per 1 cup): For cooking rice, deglazing pans, simmering vegetables, and most stews and soups. Manufacturer's recommended ratio.
- Concentrated (1 cube per 0.75 cup water): For reductions, glazes, and intensely flavored sauces where the broth will reduce by 50%+ during cooking. Use 33% more water than the recipe calls for to compensate.
For risotto specifically, use standard ratio: the rice absorbs the broth gradually over 20 minutes, and the proper ratio prevents the dish from becoming over-salted as the broth reduces.
Sodium Awareness and Reduction Strategies
The biggest challenge with bouillon is sodium content. A standard cube provides 50-75% of the daily recommended sodium intake (2300mg) in just one cup of broth. Strategies to reduce sodium without losing flavor:
- Choose low-sodium varieties: Maggi Low Sodium and Wyler's Low Sodium cubes contain 350-500mg per cube vs 1100mg for standard.
- Use Better Than Bouillon paste: 700mg per cup is significantly lower than most cubes.
- Dilute more: Use 1.5x recommended water. Add umami back with mushroom powder, dried tomato, or seaweed.
- Skip the bouillon: For delicate dishes, use water + concentrated flavor (sautéed aromatics, herbs, citrus). Many "broth" recipes work fine with water if other seasonings are robust.
- Half-and-half method: Use half bouillon broth + half water for cooking. Saltiness is reduced 50%, flavor is largely preserved.
Bouillon vs Broth vs Stock: Practical Differences
These three terms are often used interchangeably but have meaningful differences in cooking applications.
Stock is made by simmering bones (often roasted) for 4-12 hours, extracting collagen and minerals. Rich body, gels when cold, low sodium, deep flavor. Best for: braises, sauces, soups featuring the stock flavor.
Broth is made by simmering meat (and sometimes bones) for 1-3 hours, plus aromatics and salt. Lighter body, flavorful, moderately salted. Best for: most cooking applications, drinking, quick soups.
Bouillon is dehydrated broth concentrate with added salt, MSG, and flavor enhancers. Convenient, shelf-stable, high sodium. Best for: cooking applications where the broth flavor isn't featured (rice, beans, simmering pasta), camping, emergencies, busy weeknights.
For most home cooking, the practical hierarchy is: homemade stock > store-bought low-sodium broth > Better Than Bouillon > standard cubes. But all four work for cooking — the differences in flavor are subtle in finished dishes.
Storage and Shelf Life
Bouillon cubes: Sealed package: 2 years at room temperature. Once opened, transfer remaining cubes to airtight container; quality holds 18 months. Cubes are very moisture-sensitive — humid pantries can cause them to soften and clump.
Better Than Bouillon paste: Sealed jar: 2 years. After opening: refrigerate, lasts 18 months. Watch for mold or off odors.
Reconstituted broth (made from cubes/paste): Use within 7 days refrigerated, or freeze in ice cube trays for 3 months. Frozen broth cubes (each = 2 tablespoons) are convenient for adding small amounts to sauces.
Don't store bouillon cubes near strong-smelling foods (coffee, garlic, fish) — they absorb odors readily.
