My slow cooker really brings so much joy to the homemaker side of my life. Being able to cook a slow cooker beef stroganoff well is something that I’ve been perfecting for ages! I am really happy with this recipe and know you’ll love it too.
You will need to put a little more effort into this recipe than most of the easy slow cooker recipes I have here. I promise it is absolutely worth the extra effort for the delicious flavour that this dish hold!
If you fancy something a little different this week why not check out my slow cooker beef recipes.
What I like to do for this recipe is get the prep work done in advance and then when it is time to add the mushrooms, or complete the additional elements near the end, it is really quick to do still, which is part of the convenience of slow cooker meals for me!

15ml olive oil
Salt and pepper
2 medium onions (sliced as fine as you like them)
3 cloves of garlic (crushed or minced)
1 gluten free beef stock cube
10ml mustard (I use English)

Side to serve alongside it – we usually go for slow cooker mash but see below for more ideas!
My recipe for beef stroganoff in slow cooker:
If your slow cooker has a browning function then you’re going to want to use it for the first step, otherwise you’ll want to use a wok or frying pan instead.
Season your beef with salt and pepper.

Brown your beef, in batches if necessary, and set to one side if using your slow cooker pot to brown or put in the slow cooker pot if not.

Lightly brown your onion and garlic. Add this to the beef.

Once you have your beef, onions and garlic in the slow cooker pot add your beef stock, mustard and season with salt and pepper. Ensure you use just enough stock to cover the beef fully, but not to have it swimming!
Cook on high for 4.5 hours, or low for 7.5 hours. This cooking time is based on the quantities of beef I use. You may need to extend the cooking time if you double this recipe.
Once your cooking time is up it is time to prepare the mushrooms and sour cream.
Melt a little butter, or margarine and olive oil, in a frying pan or wok. Add the sliced chestnut mushrooms and cook until they are soft and slightly caramelised.
Pour these into your slow cooker pot on top of your cooked beef mixture.
Ladle a spoon of the beef stock into your pan, add the cornflour and whisk to combine. Add another ladle of liquid, around 150ml in total, and then simmer gently. Mix in your sour cream and stir well to combine.

Pour this mixture into your slow cooker and cook for another 20-30 minutes. If you were cooking on low then turn your slow cooker up to high for this final part.

Once piping hot you can stir through your chopped parsley and serve with your choice of delicious side dish.
Can you make slow cooker beef stroganoff with cream of mushroom soup?
If you want to boost the flavour of this dish, to be even more ‘mushroomy’ then by all means use a tin of cream of mushroom soup.
You’ll still want to add the sour cream near the end, and the beef stock but just use a jelly or stock cube, and don’t add any actual water to the mixture.
This is a great way to bulk out the mixture of your dish, without spending lots more money. Also, it adds a nice flavour to the dish I feel! Especially if you use fresh parsley with it.
Can you use greek yogurt instead of sour cream?
Absolutely! This can be a good way to reduce the calorie content of this dish a little, but it will alter the taste slightly. There is less of a tang, but most of the flavour in this dish comes from a combination of the ingredients, including the herbs.
I think you could use coconut cream instead of sour cream also, if you have that to hand instead.
Can you use ground beef/beef mince for slow cooker beef stroganoff?
Yes, definitely! This is a great way to save some money and do some meal planning with mince too. Ideally use very lean beef, such as 5% beef mince, so you don’t end up with lots of fat.
If you have a higher fat content mince then just brown it first and put it in a sieve, and pour hot water over, to remove as much of the fat as possible. This is a great way to reduce the fat content a little of less healthy meats.
You could even change from beef to another meat, or meat substitute, entirely. The flavour will change a little.
Quorn mince works well for this dish, particularly as a lot of the flavour is coming from the other elements of the dish, rather than just the meat itself.
Want to make this beef stroganoff with leftover roast?
I would suggest cutting the cooking time in half, at a minimum, as you don’t want to end up with tough beef. Typically cooking beef in the slow cooker makes it lovely and soft and tender, as it does for this recipe.
We often have some slices of Ninja Foodi roast beef leftover, and this is a great way to use those leftovers up without having another similar meal, or a delicious roast beef sandwich!
What to serve with beef stroganoff?
We’ve been eating beef stroganoff at least once a month for several years now and have enjoyed it with a variety of side dishes, depending on what we have in at the time. It’s quite versatile and works well with many vegetables too.
Our favourite sides to serve with this are slow cooker rice, air fryer mashed potatoes, air fryer roast potatoes, cooked tagliatelle, egg noodles, or slow cooker jacket potatoes. Sometimes we use up leftovers from the fridge and other times we make side dishes fresh to enjoy with this.

This sounds and looks so good. I think my family would love this and we're always on the look out for something different to cook in the slow cooker from casseroles.
