This is a real family favourite of ours — chicken breasts cooked in a rich chilli‑tomato sauce and finished with a generous grating of strong cheddar on top is absolutely gorgeous. This Mexican chilli chicken is packed with bold flavour, with tender chicken simmered in a smoky, deeply flavoured tomato sauce that has just the right amount of heat. It’s wonderfully comforting, quick to make and perfect for an easy midweek dinner.

Juicy chicken, warm spices and that vibrant, smoky sauce come together to create a dish that feels hearty and satisfying while still being full of colour and freshness.

Top Tip

If you prefer your chicken a little thinner — which I often do — slice each breast in half horizontally to create two flatter pieces. Not only does this help them cook evenly, it also makes the chicken stretch a little further.
