How to Cut Angled Slits in Chicken Breast

To prepare the chicken, slice the top of each breast by making 5-7 angled slits (depending on the size of the chicken breast). Cut halfway down without cutting all the way through, as shown in the pictures.

This technique helps the chicken cook faster and more evenly by reducing the thickness of the meat. It also creates more surface area for the marinade and sauce, resulting in a more flavourful and juicy dish.

How to Make Creamy Tuscan Chicken

  1. Slice the Chicken:
    Start by preparing the chicken. Take each chicken breast and make 6-7 angled slits on top, cutting about halfway down, but not all the way through. This helps the chicken cook faster and more evenly, and allows the sauce to really soak in and add flavour.
  2. Marinate the Chicken:
    Next, it’s time to marinate the chicken. Rub it with a mix of garlic powder, smoked paprika, black pepper, and rosemary. Be sure to get the seasoning into the slits you just made to add even more flavour. Set the chicken aside for a few minutes to let it absorb the spices.
  3. Sear the Chicken:
    Now, heat some olive oil in a large skillet over medium-high heat. Once the pan is hot, place the chicken breasts in and sear them for about 4 minutes on each side, until they turn a nice golden brown. Once the chicken is fully cooked through, remove it from the pan and set it aside on a plate.
  4. Sauté Onions and Garlic:
    In the same pan (don’t clean it out – you want to keep all those tasty bits from the chicken), lower the heat to medium and add the sliced onions. Cook them for about 5 minutes until they soften and caramelise. Then, add the sliced garlic and cook for another minute until it smells amazing.
  5. Add Spices and Vegetables:
    Next, add the mushrooms, bell peppers, and cashews to the pan. Let them cook for a few minutes, stirring occasionally, until the veggies start to soften.
  6. Prepare the Sauce:
    Now it’s time to make the creamy sauce. In a small bowl, whisk together chickpea flour and water until smooth. Pour this mixture into the pan along with the chicken stock and heavy cream. Stir everything together and let it simmer gently. The sauce will start to thicken and become rich and creamy.
  7. Combine Chicken and Vegetables:
    After that, add the spinach, cherry tomatoes, and some fresh red chilli slices if you like a little extra heat. Place the chicken back into the pan, nestling it into the sauce. Let everything simmer together for about 10 minutes, giving the sauce time to thicken and the chicken to warm through.
  8. Serve:
    Finally, your creamy Tuscan chicken is ready to serve! Plate it up and enjoy it hot, either on its own or with your favourite side, like cauliflower rice or roasted vegetables.

 

Tips to Make the Best Creamy One Pan Tuscan Chicken

  1. Slice the chicken breast on an angle halfway down: This will help the chicken cook faster and more evenly by reducing the thickness of the meat. It also helps the marinade and sauce soak in, making the chicken juicy and flavourful.
  2. Use fresh ingredients: Fresh ingredients like garlic, onion, and herbs will give your dish a vibrant and delicious flavour.
  3. Don’t overcook the chicken: Overcooking the chicken can make it dry and tough. Be sure to cook it until it’s just done and still juicy.
  4. Use a large skillet: A large skillet ensures the chicken and vegetables cook evenly and that the pan isn’t overcrowded.
  5. Add the spinach at the end: Adding spinach towards the end of the cooking process will help it retain its bright green colour and fresh flavour.
  6. Let the sauce simmer: Allowing the sauce to simmer for a few minutes will help it thicken and develop more flavour.
  7. Avoid lumps when using chickpea flour or cornstarch as a thickener: Don’t pour the thickener directly into the dish. Instead, mix the flour with water in a small bowl first, then add it to the dish. Make sure the water isn’t boiling.

  • Prepare the Sauce: Reduce the heat to low-medium. In a small bowl, whisk together chickpea flour and water until smooth. Add it to the pan, along with chicken stock and heavy cream. Bring the mixture to a simmer.
  • Finish Cooking: Add the spinach, cherry tomatoes, red fresh chilli (if using), and the seared chicken back to the pan. Simmer for about 10 minutes, or until the sauce thickens and the chicken is heated through.
