Step-by-Step Guide to Making Mary Berry Mustard Chicken

Season the chicken – Lightly season both sides of the chicken breasts with salt and pepper. This helps flavour the meat from the start.
Brown the chicken – Heat the butter and olive oil together in a large pan over medium heat. Add the chicken and cook until lightly golden on both sides. The chicken does not need to be cooked through at this stage. Remove and set aside.
Soften the onion – Add the chopped onion to the same pan and cook gently until soft and translucent. Stir regularly and avoid browning to keep the sauce mild.
Add the flour – Sprinkle the flour over the onions and stir well. Cook for about a minute to remove the raw flour taste and form the base of the sauce.
Pour in the stock – Add the chicken stock gradually, stirring constantly to keep the sauce smooth. Let it simmer gently until slightly thickened.
Stir in cream and mustard – Lower the heat and add the double cream, Dijon mustard, and wholegrain mustard. Stir gently until fully combined and glossy.
Return the chicken – Place the chicken back into the pan, spooning the sauce over it. Cover and simmer gently until the chicken is cooked through and tender.
Finish and rest – Taste and adjust seasoning if needed. Let the dish rest for a couple of minutes off the heat so the sauce settles before serving.

What I Got Wrong (And How I Fixed It)

Overpowering mustard taste – Too much mustard at once caused this; balancing with cream fixed it.
Dry chicken – Cooking too long at high heat was the issue; gentle simmering worked better.
Thin sauce – Not simmering long enough; extra time thickened it naturally.
Split sauce – Heat was too high after adding cream; lowering it kept the sauce smooth.

FAQs

Why does mustard chicken sometimes taste too strong?

Mustard chicken can taste overpowering if too much mustard is added at once or if a very hot mustard is used. Adding mustard gradually and balancing it with cream helps keep the flavour warm and rounded rather than sharp.

How do I stop the mustard sauce from splitting?

The sauce can split if it boils after the cream is added. Keep the heat low and let the dish simmer gently. Stir slowly and avoid rapid bubbling to maintain a smooth, creamy texture.

Can I make mustard chicken ahead of time?

Yes, mustard chicken can be prepared a few hours in advance. Reheat it gently over low heat, adding a splash of stock or milk if the sauce has thickened too much.

How do I thicken mustard chicken sauce naturally?

Allow the sauce to simmer uncovered for a few extra minutes so it reduces. This thickens the sauce without needing extra flour or cornflour and keeps the flavour balanced.
