If you love a bit of Bisto on your roast, but you’re not sure how much you’re going to need per person, then look no further because I’ve put this article together to help you work out the portion size you need.
The average amount of Bisto gravy granules or powder per person for an average-sized serving is one heaped teaspoon mixed with 70ml of boiling water. For a more generous serving, allow for 1.5 teaspoons with 105ml of water.
Read on to see how much Bisto you need for multiple servings, along with some tips on how to make your gravy thicker and how to prevent it from going lumpy.
How Many Bisto Granules to Use Per Person
When it comes to gravy some people can’t get enough, but others just like a little bit over their meat or veg.
So the table below shows how much Bisto You will need per person for both generous and not so generous (average) portions.
This is based on a heaped teaspoon of Bisto weighing 6g and 70ml of boiling water per person.
The image shows what an average serving looks like on the plate, if this isn’t enough for you then go with the generous serving (see chart below).

How Many People Does Half a Pint of Bisto Serve?
The instructions on the side of a Bisto jar or pack state that you need four heaped teaspoons of Bisto with half a pint (280ml) of water, but it doesn’t state how many people this serves.
I’ve tested this on my own family and can confirm that half-pint of Bisto Gravy is enough for four average servings or two to three more generous servings.
How to Make Your Bisto Gravy Thicker
The recommended amount on the side of the jar is not that thick, so if you like your gravy thicker then you will need to amend the Bisto to water ratio a little.
To make your gravy thicker, add an extra half a level teaspoon of granules/powder per portion (see chart above).
Alternatively, you can add the boiling water a bit at a time until you reach your desired thickness, but keep in mind that if you use less water you might have less gravy per person.
How to Stop Bisto Gravy From Going Lumpy
A great way to stop Bisto or any powdered gravy from going lumpy is by mixing it to a paste with a little cold water before you add the boiling water.
Or to make sure the gravy is as hot as possible you can mix the paste in a pan, add the boiling water and keep it warm over low heat.
The Bisto Best version makes a smoother gravy when compared to the original granules.
When I’m making Bisto gravy using the original granules, I usually leave it to stand for five minutes before serving. By giving it a little extra time, any lumps tend to melt away by the time you’re ready to serve.
