Ingredients

  • 1 cup 225 ml heavy whipping cream or sour cream
  • 2 tbsp 2 tbsp green pesto
  • ½ ½ lemon, the juice
  • 30 oz. 900 g chicken thighs
  • 3 tbsp 3 tbsp butter
  • 1 lb 450 g cauliflower
  • 1 1 leekleeks
  • 4 oz. 110 g cherry tomatoes
  • 7 oz. 200 g (425 ml) shredded cheese
  • salt and pepper

Instructions

Instructions are for 6 servings. Please modify as needed.

  1. Preheat the oven to 400°F (200°C).
  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 greased 9 x 13 inch baking dish, and pour in the cream mixture.
  5. Chop the leek and cherry tomatoes. Chop the cauliflower into small florets. Top chicken with leek, tomatoes and cauliflower.
  6. Sprinkle cheese on top and bake in the middle of the oven for at least 30 minutes or until the chicken is fully cooked. If the casserole is at risk of burning before it's done, cover it with a piece of aluminium foil, lower the heat and let cook for a little longer.

Tip!

Green it up! A rich dish like this only gets better if you serve it with a side of fresh leafy greens. Dress with a generous drizzle of olive oil, some balsamic vinegar and a sprinkle of sea salt.

Meal prep

This dish can be prepared by frying the chicken ahead of time. You can assemble the entire casserole and keep in the fridge for a day before baking it. Just make sure you let it come to room temperature before placing in the oven. It's also good to give it a stir since the pesto can sink to the bottom.

If you have chicken or turkey leftovers they are perfect for this dish. Just skip step 3 in the instructions and you are good to go!

If you're short on time you can also use a rotisserie chicken. Take the meat from the bones and divide into bite-sized pieces before adding it to the baking dish.

Storing and reheating

If you intend to eat the casserole within 2-3 days you can store it in the fridge. Otherwise it's better to place the casserole in the freezer where it will last up to 3 months. Make sure your dish is suitable for freezing.

Let thaw in the refrigerator the day before you plan on serving it. Don’t place a cold baking dish straight from the fridge into a hot oven as this can cause your dish to crack. Reheat the casserole in the oven at 300°F (150°C) until thoroughly warm. When thawing and reheating this casserole the result may be a bit more liquid but the flavor will still be good.

    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.
  12. Claire
    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.

    FORGET the calories, my dahrlin... they are NOT RELEVANT.... old brainwashing... low carb high fat is key... calories in calories out need to be thrown OUT the window. Your Fitness Pal, as most of these type of things still think the old way and have LOW FAT on the brain... ignore it...

    Erin, If you are really abiding by the LCHF rules, weight will literally fall off of you. I started on the 1st of January and have lost 35 lbs. I have high blood pressure, high cholesterol and high blood sugar. I can't wait until my next lab test. I should have another 35 lbs off before then. I use fitness pal's online version. I hate that I have to manipulate what I've eaten in order for it to allow me to complete my entries. I just use it to keep track of my carb intake.

    Forget the calorie count.

    I have written in before about how much I love this recipe, just as the recipe is written. I make it
    About once a week. Tonight I chopped up a couple chipotle peppers in adobe sauce, and mixed them
    In with the cream sauce and oh my!!!! Awesome!

    This was delish! I have to admit that I was a little doubtful when I tasted the sauce prior to putting it in and baking, but when all the ingredients came together it was wonderful. I took the suggestions from other comments and steamed the cauliflower in the microwave and sautéed the leeks (adding some garlic and a few mushrooms) before putting them over the chicken. I also added the combo of 1/4 c heavy cream, 1c sour cream, 2 tbsp cream cheese and some parmesean cheese the sauce, which helped thicken it a bit. I will absolutely be making this again soon! There seem to be endless ways to customize this recipe in order to keep it exciting. Thanks for sharing!

    Can something else be instead of leeks and pesto?
  21. Tyler
    Just used this one. Subbed mushrooms for the cauliflower and used mozzarella cheese (I also didn't eat lunch). Also, not a big fan of chicken thighs and so I used breasts instead. It was amazing.

    Eat until you are satisfied is what the videos says.

    Annb, I used green salsa (Aldi) and white onion. It was delicious.

    This is delicious! My family loves it. I have not baked it with the cheese on top. Instead, I bake it without the cheese and when it is done, I serve it with shaved parmesan on top. Very good!
  27. James
    I'm trying to understand the nutritional information. Taking this recipe as an example, if I add up the grams as written, I get a total of 100 grams/serving. How, then, does 56 grams of fat equate to 75%? I'm having trouble understanding the numbers. Can anyone explain?

    Nevermind. :-) I think I figured it out.

    I made this last night and we really enjoyed it. Usually I try the recipe 'as is' the first time, then tweak it afterwards, but due to all of the conflicting comments I changed it up a bit. I tossed the chicken and veggies with some olive oil, salt, and pepper, and roasted on a sheet pan until nicely done (30 minutes at 400 degrees worked perfectly), then topped with sauce and cheese and returned to the oven for a few minutes to get nice and melty. I used 4 oz cream cheese and 1/2 cup heavy cream in the sauce because I wanted it to be thick and creamy. Delicious and so easily customized for different vegetables and seasonings!

    Need to know how much is a serving. As only eating 20 carbs per day for now.
  32. Richard
    This meal was INCREDIBLE!!! When I walked in the house, I knew that I was in for a real treat, because it was like walking into an Italian restaurant. The pesto made everything smell so great, and the flavor was amazing... I just couldn't get enough! Luckily, there was enough for us to enjoy it as lunch the day after... Just goes to show that you don't need crazy carbs to eat like royalty!
  33. Suzy
    Made this today and after reading these comments I think I may have done something wrong. The sauce was very watery, soup/like. It didn’t resemble a casserole at all. Any suggestions?

    It would be nice to have a button that would give us the recipe on a printable format.

    Tom, there is a print button directly under each recipe and they print beautifully with nice clear large print and photos. Have printed many.

    Is this boneless or bone in chicken thighs? I've made it a couple of times but with boneless and it was lovely. Got some bone in, skin on thighs I want to use up, guess I'll need to cook for longe? Advice pls.
  36. Liz
    Like Suzy I found this very watery. I used half cream and half sour cream for the sauce. Will thicken sauce tomorrow night for the leftovers. Tasty though.

    Hi Jeffrey,
    I sub the cottage cheese for ricotta. No sticking to pan (used butter and spray) and they turned out pretty good.
  38. Melinda Hooton
    With the Keto Chicken Casserole is there anything else I can use in place of the green pesto? I'm feeding a group and one of them says they are allergic to basil. The only green pesto I can source is basil pesto. I could really use some advice on this! Thanks.

    It states (shredded cheese) what type of cheese??
  40. Fiona
    Loved this recipe - very tasty. I used a covered dish from the outset in the oven and left it in for 1 and a half hours to make sure the chicken was cooked. I did check it after 40 mins but it was still very raw. However, its well worth the wait - it was delicious!
  41. Jane
    The veg were uncooked - pre-cook if you don’t like squeaky leeks etc ... !

    They do show all the nutritional facts - down at the bottom of the recipe you need to click on the + and it will show you. This particular recipe per serving?

    I'm a little confused as to the nutritional information on the side tab. Why do they count "net carbs" when they explicitly say elsewhere on the site to beware of anything that has "net" carbs in the info?

    Hi Mike!

    We don't count the fiber because it doesn't increase your blood glucose.

    But commercial products that states few net carbs in their nutritional info are often highly processed and also often uses potentially unhealthy sweeteners.

    Hello. it says to cook the chicken before you bake it!
  46. Sonya
    This was lovely. I got tomato pasto instead of the green one, but it was still lovely.

    Just tried this recipe. I love the flavor. I did exactly what the recipe instructed. I know that these types of dishes tastes better the next day,when reheated. My family was a bit disappointed because the sauce was very thin. Next time I think I will make it with sour cream 3/4 cup, and heavy whipping cream 1/4 cup. I also think the size pan that they recommended is too long/big. The chicken thighs kind of shrink in the dish and then just sit in the sauce, plus the toppings just slide off. With that said I'll use a smaller dish, mix all the toppings together, including the sauce, and then just pour it over the chicken. Also... too much leek.. adjust the recipe to a half and soak it for about 30 minutes before mixing it together should do the trick.

    Cilantro is the alternative to basil. Either can be used when making pesto.

    Made this for dinner tonight exactly as per the recipe. It was delicious!! Used heavy cream, skin on/bone in thighs and smoked Gouda cheese. The sauce is quite runny but still delicious- no leftover sauce on the plate.
    I discovered halfway through that the Smoked Gouda was not melting, but rather getting toasted and crunchy- ops. I took it out and grated some cheddar over it to try to “save” it. The end result was super tasty as had a nice little crunch from the Gouda. Happy mistake. 😋

    Has anyone made this with Quorn? If so does Quorn and chicken weight similar amounts? Totally get the macros will be v different and the cooking time. Cheers

    The nutritional info on here is wrong. They say this is 6g of carbs but every other place I calculate that its 8.6g carbs.
  53. Kris
    I thought this recipe was very bland and watery. I just did not like it at all. A waste of time and money.
