Slow cooker wild rice and mushroom soup

The only thing better than a creamy wild rice and mushroom soup? A creamy wild rice and mushroom soup that’s made in the slow cooker! Dump everything in, and boom. A super tasty dinner.
In case the photos aren’t enough to convince you, let me tell you a bit about this soup. It’s got garlic, heaps of mushrooms, parsley, cream and wine. Yes, all of that. The most creamy, flavourful and luxurious mushroom soup you’ll ever have. Nobody needs to know quite how easy it was to make.

Start off by cooking the onions, garlic and mushrooms in the slow cooker until they’re nice and soft and fragrant, along with a good glug of dry white wine (at this point it already smells amazing). I used this Chilean sauvignon blanc from Premier Estates. It’s nice and crisp, and slightly fruity. I’m no wine expert, but I thought it went really, really well in this mushroom soup – it added a lovely depth of flavour. It was pretty great served in a glass at the side too…

Then just add the rice. In the past I’ve not had a huge amount of success cooking rice in the slow cooker – I remember attempting to make a risotto in the slow cooker one time, and ending up with a big smooshy mess. It was not pleasant.
I’ve realised that the key is to not overcook the rice – it may sound obvious, but when you’re used to putting things in the slow cooker and leaving them to bubble away all day long, it’s an easy mistake to make! Once you add the rice, it will only need about two more hours to cook – still plenty long enough for you to get a few jobs done while it’s cooking, but not so long that you can completely forget about it. So it’s probably best to save this recipe for a day when you’ll be at home!

Once the rice is fully cooked, you can finish everything off with a dash of cream, and plenty of fresh parsley. I like a really good pinch of black pepper too. And don’t forget the extra glass of Premier Estates sauvignon blanc to wash it all down!

Hi! How would you recommend storing this and for how long? Thanks
Hi, I’d pop it in a bowl with a plate over the top in the fridge for up to 3 days. Just make sure you reheat it very thoroughly, as rice can be a bit funny and can cause food poisoning if not reheated properly. I wouldn’t stretch it any further than 3 days because of the rice. You can add a dash more liquid when reheating if needed!
Hi, is it really necessary to cook the mushroom for 4 hours? I’m worried that would overcook the mushroom?
Not necessary no, but you need to cook all the other ingredients too, and it does the mushroom no harm :)
1) Has anyone tried substituting the wine with a non-alcohol beverage?
2) There is a caution regarding overcooking rice. Is it possible that those who have commented on recipe failure may have left the rice cooking for too long. Hence, the rice absorbing too much broth?
I haven’t tried using a different liquid but I’m sure veggie stock would work fine!
I experienced the same results as others. My dish has the consistency of risotto (and I stopped the cooking 30 minutes earlier). There is either an error in ingredient measurements or the kind of rice needs to be specified. I used a pre-mixed wild and long grain rice. I think that half the rice or double the stock is the only way to fix this recipe in the future.
Thanks for the feedback Patricia! I’ll take another look at this recipe in the new year as a lot of people have had trouble with it. Might need a redo :)
Delicious soup! I tweaked the recipe to make it vegan. 1:1 pureed tofu instead of cream.
I also served over kale (shredded without the stems) instead of the parsley and drizzled truffle oil on top just before serving.
I did end up quadrupling the broth as the rice soaked up all the liquid (I checked on the soup every 30 minutes after adding the rice since others commented about liquid issues and first doubled then added another 2 quarts of broth for a total of 10 cups of broth).
Thanks for the tips, glad you could make it work for you! :)
