Cook your pasta in well salted boiling water, undercooking by 1 minute. Reserve a cup of pasta water before draining.

Flatten the chicken breast to an even thickness (about 1-1.5cm), I do this by laying some plastic wrap over the top and hitting with a rolling pin.

Season the breast well with salt and pepper on each side then dust with the flour.

Heat the olive oil in a fry pan over a medium high heat and fry the chicken for 2 mins each side (or until cooked through if yours is thicker).

Lightly wrap in foil and set aside.

Heat the butter over a medium heat and gently fry the garlic for a minute, it shouldn't brown at all.

Add the rosemary and cook for a further 30 seconds.

Pour in the cream and bring to a very gentle simmer (lower the heat if you need, it shouldn't be boiling).

Add the parmesan in 2 or 3 separate lots, mixing and letting it melt in between each addition.

Add the pepper and lemon juice and mix in quickly.

Add 1/4 cup of pasta water and let it gently simmer for a 2 - 3 minutes to thicken slightly.

Add the cooked pasta, toss and let it gently bubble away for a minute or two.

Slice the chicken then serve the with the pieces on top or tossed through.
