2Chop three chicken breasts into bite-sized pieces and add two tablespoons of cornflour or cornstarch, plus half a teaspoon each of salt, black pepper, and garlic powder. Toss to coat thoroughly.
3Add three tablespoons of oil to a large frying pan and heat over a medium heat. Add the chicken and fry for six to seven minutes, turning occasionally, until golden and cooked through.
4Remove the chicken from the pan using a slotted spoon and place in a warm bowl.
5Add a finely diced small onion to the remaining oil and cook for two to three minutes, stirring often, until softened.
6Add three minced cloves of garlic, a quarter of a teaspoon of salt, and half a teaspoon of black pepper. Stir together and cook for a further minute.
7Add 180ml of strong chicken stock and 180ml of double or heavy cream. Stir together, bring to a boil, and simmer gently for three minutes.
8Once the sauce has thickened slightly, stir in a tablespoon of fresh lemon juice.
9Drain the pasta, reserving about a cup of the starchy cooking water.
10Add the pasta to the pan with the creamy sauce and sprinkle over 50 grams of finely grated parmesan.
11Use tongs to lift and drop the pasta in the sauce until fully coated.
12Add a few splashes of the reserved pasta water to loosen the sauce if needed.
13Add the cooked chicken back to the pan and stir through. Heat for a further minute to ensure the chicken is hot, then turn off the heat.
14Divide the pasta between bowls, top with chopped parsley, a sprinkle of black pepper, and grated parmesan, and serve with garlic bread.
