This recipe was more like a soup. After the oven cooking time was up, I removed the chicken and reduced on the stove for 20 minutes. Even then, the base was that of a thick soup. 800 ml of stock was too much. Not a do over for me.
We’re sorry to hear you weren’t a fan of this recipe. It is a saucy casserole but our food team suggest that you could quickly thicken it by adding 1 tbsp cornflour mixed with 1 tbsp cold water, then bringing to a rapid simmer for a minute; there will still be lots of sauce, but it won’t be as loose. Thanks for your feedback.
This was one of the loveliest tasting casseroles I’ve made. I also added some butternut squash cubes as didn’t have quite enough chicken Super!
Super tasty with minimal effort. Definitely one to do again.
