  2. Mix cream (or sour cream) with pesto and lemon juice. Salt and pepper to taste.
  3. Season the chicken thighs with salt and pepper, and fry in butter until they turn a nice golden brown.
  4. Place the chicken in a baking dish, and pour in the cream mixture.

    Definitely a five-star recipe for me! I made it with boneless skinless chicken thighs, didn’t think about making it with the skin on? Don’t know if I should try it that way?
    The sauce was a little on the thin side, but so delish! Made it just as the recipe called for, and it’s delicious leftover heated up in the microwave. I’m so glad I found this website!

    So good! Loaded up on the lemon juice in the cream sauce and it really added some flavour.

    Been sitting on this recipe for a while now and finally tried it last night.
    Substituted cut up chicken breast for thighs as I am not a fan of thighs, did everything else to the letter and man sooo tasty, will most definitely be making again! Thank you so much for this recipe!

    I made a sundried tomatoes pesto and added to the cream. Steamed cauliflower, sauteed leeks. Used a rotisserie chicken, shredded. This is not a thick creamy sauce that I think we are expecting, but it still was tasty. Will make again.

    I guess I won't be using anymore Diet Doctor recipes unless they update the nutritional values to show cals, fat, protein and net carbs! Love the recipe, but don't have time for the math.

    Excellent family meal! I didn’t have any pesto so used a tbsp minced garlic instead. Also poured a bit of olive oil over the top and put on broiler for last 4 min just to give the cauliflower a more roasted look. Very tasty and filling.

    What an awful recipe. All of the instructions that actually make it work are in the comments like precookinf the leeks and cauliflower, cooking for longer under a lower temperature. It’s a good thing I was using leftover cooked chicken thighs or the meat probably wouldn’t have cooked.
