Stock Cubes Buying Guide: How to Choose the Right Flavour, Salt Level and Pack Size

Stock cubes are a practical cupboard staple for UK households. They can add savoury depth to soup, gravy, casseroles, pies, stews and sauces without requiring a homemade stock pot to simmer for hours. However, choosing the right pack involves more than picking chicken, beef or vegetable flavour from the shelf.

Different products vary in dilution instructions, salt content, allergens, dietary suitability and packaging format. A low-priced multipack may not suit your recipe, while a product marketed as richly flavoured may contain ingredients that matter to your household. The following guide highlights common buying traps and the specifications worth checking before you order.

Common stock cube buying pitfalls

1. Assuming every cube makes the same amount of stock

Stock cubes do not follow one universal preparation ratio. Several Oxo varieties are designed to dissolve in 190ml of boiling water per cube, while Knorr lamb stock cubes use approximately 450ml. Knorr Rich Beef Stock Pots can be dissolved in 500ml of boiling water, or 750ml for a lighter stock.

Using too much water can produce a weak soup stock or gravy stock. Using too little may make a dish overly salty. Always check the preparation instructions rather than judging by cube size or pack appearance.

2. Focusing on flavour while overlooking salt and allergens

Stock cubes are concentrated seasonings, so salt levels can be significant. For example, the standard Oxo Chicken Stock Cubes list 0.77g of salt per 100ml prepared portion, while Oxo Reduced Salt Chicken Stock Cubes list 0.54g per 100ml portion and state that they contain 25% less salt than the standard version.

Ingredients also differ between apparently similar products. Wheat appears in several Oxo cubes, Oxo vegetable cubes contain wheat and barley, and Knorr Beef Stock Cubes list celery as an allergen. Check the current packaging if someone in your household has an allergy or follows a specific diet.

3. Buying a large multipack without considering usage

A larger pack can be convenient for meal planners and families, but it is only good value if you use the cubes before their best-before date and can store them in a cool, dry cupboard. Smaller packs may suit occasional cooks, flat shares or households that rotate between chicken stock cubes, beef stock cubes and vegetable stock cubes.

Individually wrapped cubes can also help protect the remaining portions from moisture. Stock pots, meanwhile, are ready to add directly to a dish but may have different storage and preparation requirements.

Core specifications to check before buying

Flavour and intended recipe

Choose the stock according to the main dishes you cook:

• Chicken stock cubes: suitable for chicken pies, soups, casseroles, sauces and rice dishes.
• Beef stock cubes: useful for mince-based meals, chilli, stews, cottage pie and rich gravies.
• Lamb stock cubes: suited to shepherd’s pie, lamb stew and sauces served with roasted meat.
• Vegetable stock cubes: a flexible base for soups, pasta, risotto, casseroles and meat-free meals.

For vegetarian stock cubes or vegan stock cubes, read the full ingredient list and suitability statement. A vegetable flavour does not automatically mean every product is vegan.

Dilution and portion size

Check how much prepared stock each cube or pot produces. This affects both recipe planning and salt concentration. A product intended for 190ml may be more suitable for adding concentrated seasoning directly to a casserole, whereas a cube designed for a larger volume may work better as a soup stock.

Stock pots can be convenient for larger dishes. The Knorr Rich Beef Stock Pot is intended for direct addition or dilution in 500ml of boiling water, with 750ml suggested for a lighter stock.

Salt, allergens and dietary information

Compare the per-100ml prepared values, not only the figures per 100g of dry product. This gives a more realistic indication of how much salt enters a bowl of soup or serving of gravy.

Also look for:

• Reduced salt stock cubes if you want to moderate salt in your cooking.
• Gluten-free stock cubes where the product specifically states this suitability.
• Wheat, barley, celery, milk, fish, soya or mollusc declarations where relevant.
• Vegetarian or vegan suitability statements.
• Pack quantity and individual cube weight.

Adding a cube to a recipe that already contains gravy granules, salted butter, cured meat or soy sauce can increase the overall salt level, so taste before adding extra seasoning.

Frequently asked questions

How much water should I add to a stock cube?

It depends on the product. Many Oxo cubes specify 190ml of boiling water per cube, while other products use larger volumes. Follow the preparation instructions on the pack, particularly when making soup stock or gravy.

Are reduced salt stock cubes suitable for every recipe?

They can be used in the same types of dishes as standard cubes, but the flavour and salt balance may differ. Taste the dish before adding more seasoning. Also check the product label, as “reduced salt” does not mean salt-free.

Do stock cubes expire?

Stock cubes generally have a long cupboard life when stored in a cool, dry place, but you should follow the best-before information on the packaging. Keep opened products away from moisture and check that individual wrappers or stock pot seals remain intact before use.
