4I had some beautiful dutch carrots in my fridge so I served those with this dish as well but its completely optional. I just washed and patted them dry, placed them on a lined oven tray and brushed them with some melted butter and then drizzled them with honey and finished them off with a sprinkle of sea salt. I then roasted them for 30-35 minutes in a 180 deg oven.

Great recipe. I added 1 cup pasta plus 1 extra cup of water to the slow cooker. Used sour cream for the last half hour instead of cream and wholgrain mustard instead of dry. Delish 😁

Tasted great! We threw in some big chunks of potato and carrot too though 🙂 i should have thickend it a little at the end but still tasted good. I pulled the chicken at the end and stirred it all too

Loved this! I substituted extra stock for the cream, and used whole grain mustard and it was yum! Even my fussy kids ate it (well, after picking out the mushrooms)!

Sure 🙂

Thank you.

Do you feel Dijon would work?

I would think the regular yellow creamy kind of mustard if that helps 🙂

Hi Lauren ! yes sometimes you need to thicken it up with cornflour. I think it also depends on the quality of cream and if you use a thickened cream or not. You could also add a 1-2 tbs of cream towards the end of the cooking time aswell as your cornflour. So glad you still enjoyed it xxxx

First time cooking a slow cooked meal and i chose this recipe. It didn’t turn out nice and cream like the photo and i had to use cornflour to thicken it. Served on some rice. Tasted good though.
