Chicken and Vegetables with Leek and Mustard Sauce

Jump to Recipe

I love all-in-one meals in the Thermomix and this one has quickly become a favourite in the various iterations of testing. It takes classics like chicken, leeks and dijon mustard to make a tasty everyday dish – add in some vegetables and you’ve got a complete meal.   

Leveraging the Thermomix’s ability to cook different components of the meal at the same time, I steam the chicken and vegetables in the Varoma while the sauce cooks in the Thermomix bowl. The sauce is made with leeks, garlic, stock concentrate, milk, Dijon mustard and parsley.  It gets an extra kick of flavour as the chicken and vegetables cook in the Varoma.  This recipe also includes a super easy technique for chopping parsley in the Thermomix. 

Chicken and Vegetables with Leek and Mustard Sauce

This recipe is all about the leek and mustard sauce. Chicken and vegetables are steamed in the Varoma while the sauce cooks in the Thermomix bowl.
