Ran out of vegetable stock mid-recipe? Chicken stock will do the job at 1:1 — but only if you also adjust for what the swap takes away or adds. Water, milk and stocks swap one-to-one by volume — a cup of one replaces a cup of another — so the measuring is the easy part. What changes is the flavour and richness of the finished dish: stock brings salt and savoury depth, milk brings fat and a gentle sweetness, and water brings nothing at all, which is sometimes exactly what a dish needs. This page gives the ratio, shows it in a table, and walks through three real dishes so you can see where the swap improves things and where it quietly flattens them.
The ratio, in a table
The table below converts vegetable stock to chicken stock for the amounts you are most likely to meet. The rule is always the same: 1:1.
| Vegetable stock called for | Chicken stock to use |
|---|---|
| 1/4 cup | 1/4 cup |
| 1/3 cup | 1/3 cup |
| 1/2 cup | 1/2 cup |
| 2/3 cup | 2/3 cup |
| 3/4 cup | 3/4 cup |
| 1 cup | 1 cup |
| 1 1/2 cups | 1 1/2 cups |
| 2 cups | 2 cups |
By weight, one cup of vegetable stock is about 240 g (poured, USDA). Our density table does not list a grams-per-cup figure for chicken stock, so no weight is given for it here — measure it by volume. All weights on this page are approximate; verify with a kitchen scale when the result matters.
Worked examples
Example 1: Chicken soup
A recipe for a vegetable soup calls for 1 cup of vegetable stock. Using the ratio, that becomes 1 cup of chicken stock. Add the stock with the vegetables, and season the soup well — it will need less salt than the vegetable version, because the chicken stock is already salted. The soup will be richer and more savoury.
Example 2: Risotto
A recipe for a risotto calls for 2 cups of vegetable stock. Using the ratio, that becomes 2 cups of chicken stock. Add the stock a ladle at a time, as usual, and let the rice absorb it. The risotto will be richer and more deeply flavoured than the vegetable version, with a savoury depth that suits a mushroom or a chicken risotto.
Example 3: Stew
A recipe for a stew calls for 1 cup of vegetable stock. Using the ratio, that becomes 1 cup of chicken stock. Add it to the pot with the vegetables and let the stew simmer. The stew will be heartier and more savoury, with a richer body.
What changes in the result
Chicken stock in place of vegetable stock makes the dish richer and more savoury, with a deeper, meatier flavour. Vegetable stock is light and clean, with the flavour of the vegetables it was made from; chicken stock is richer, with a savoury depth and a little body from the gelatin in the bones. The ratio is one-to-one, so the measuring is simple, and the swap works well in a soup, a stew or a risotto, where the extra richness is welcome. The main thing to watch is the salt: chicken stock is usually saltier than vegetable stock, so the dish may need less salt, and the flavour will be meatier — which matters if the dish was meant to be vegetarian.
When not to substitute
Do not make this swap where the dish must be vegetarian or vegan. Chicken stock is made from chicken, so a vegetarian or vegan dish will no longer be vegetarian if you use it — and a guest who chose the dish because it was meat-free will not thank you. Do not use it in a delicate vegetable soup either, where the chicken flavour would overwhelm the vegetables. And do not forget the salt: chicken stock is usually saltier than vegetable stock, so hold back the salt the recipe asks for until you have tasted the finished dish.
Practical guidance
Taste the liquid you are swapping in before it goes into the pot: a salty stock can make a dish over-salted once it reduces, and an unsweetened milk can curdle if it is boiled hard with acidic ingredients. Add stock or milk gradually and hold back the seasoning until the dish is nearly done, because the substitute changes the salt balance. When milk replaces water in a dough or batter, watch the browning — milk sugars colour faster in the oven, so check a few minutes early and cover the top loosely with foil if it is darkening too fast. Keep stocks refrigerated and use them within a few days, or freeze them in measured portions for cooking. All amounts on this page are approximate; a kitchen scale or a marked jug is the most reliable way to measure liquids for a large batch.
Frequently asked questions
How much chicken stock do I use instead of 1 cup of vegetable stock?
Use 1 cup — the ratio is 1:1. One cup of vegetable stock is about 240 g (poured, USDA); our density table does not list a grams-per-cup figure for chicken stock, so measure this swap by volume.
Will the dish be richer?
Yes — chicken stock is richer and more savoury than vegetable stock, with a deeper, meatier flavour and a little body from the gelatin in the bones. The dish will be heartier, so it suits a soup, a stew or a risotto.
Is chicken stock saltier?
Usually, yes — chicken stock is often saltier than vegetable stock, so the dish may need less salt. Hold back the salt the recipe asks for until you have tasted the finished dish.
Can I use chicken stock in a vegetarian dish?
No — chicken stock is made from chicken, so the dish will no longer be vegetarian. If the dish must be vegetarian, keep the vegetable stock, or use water with extra herbs.
Can I use chicken stock in a delicate vegetable soup?
Not as a straight swap. A delicate vegetable soup depends on the clean, light flavour of vegetable stock, and chicken stock will overwhelm the vegetables. Use the swap in a hearty soup or a stew, and keep vegetable stock for a delicate one.
Scaling the swap up or down
A liquid swap scales one-to-one by volume, so double the recipe and you double both numbers — but the seasoning does not scale in the same way. A doubled pot of soup needs slightly less than double the salt, because the liquid reduces and concentrates as it simmers, and a doubled dough needs the same proportion of liquid but a little more kneading time to come together. The safe way to scale up is to add the scaled amount of liquid, then season in stages, tasting as you go. For a very large batch, keep a little of the liquid back and add it at the end: a dough that is too wet is hard to fix, while a dough that is a touch dry can be loosened with a splash. If you are scaling down to a single serving, measure the liquid in a marked jug rather than by eye — a small error matters more in a small batch.
If the swap goes wrong — and how to store the substitute
If a milk-based sauce curdles, take it off the heat immediately and whisk in a splash of cold milk — do not boil it again, and next time add the milk late in the cooking and keep the heat gentle. If a soup tastes flat after the swap, it needs salt and time: add the salt a little at a time, let the soup simmer so the flavours develop, and finish with fresh herbs. If a dough made with milk browns too fast, cover the loaf loosely with foil and check it five minutes early next time. Keep stocks refrigerated and use them within a few days, or freeze them in measured portions so you can defrost exactly what a recipe needs.
