Hi, How could I do this in the slow cooker? I’ve looked on the conversion article, but that only states slow cooker to insta pot? Not the other way around? I want to make a big batch so I can pop in the freezer.
Many Thanks xx

Very tasty, made on the stove as I have no crock pot or anything. Added leek and onion first, then potato and carrot , a minute later the celery, then broccoli let simmer for a few minutes in half of the stock and then added the orzo. Topped up the stock when it started to be absorbed

Hi there
Can this be batch and freeze ???


    HollyThursday 24th September 2020

    Hi Sarah, yes this is fine to freeze! Just remember to date and label when putting in the freezer and defrost overnight before reheating. Hope that helps!


Christina CloseTuesday 18th August 2020

Hi, How would I make this if I don’t have an Instant Pot?




    HollyWednesday 26th August 2020

    Hi Christina, we haven’t tried this recipe on the hob but you could try adding the ingredients to a pan and set on a medium heat, cover with a lid and bring to the boil. Lower the heat and simmer until the vegetables are soft and the orzo is cooked through. Let us know how you get on!

How long would I cook this in a slow cooker for please?


    HollyFriday 16th October 2020

    Hey Karen, We have recently published an article on slow cooker and instant pot conversions which you can find here if you scroll down there is a table that gives a rough guide for how to convert recipes. These times are just a rough guide only, so please make sure that everything is cooked through before serving. If not, just cook it for a bit longer. Hope that helps!
