What’s To Love About This Recipe

  • This isn’t your standard chicken thigh recipe! This includes a zesty twist on chicken with the most delicious creamy lemony sauce.
  • I’m willing to bet this is one of those recipes that you won’t tire of anytime soon! It’s one of our family favorites because it tastes luxurious but is really pretty simple to prepare.
  • The combination of creamy lemon sauce and chicken thighs packs so much flavor. It’s a dish that is filling but also not too heavy.
  • One of the nice things about the slow cooker is that the thighs won’t dry out like they might with other cooking methods. Since the thighs are slow-cooked in liquid, they stay juicy during cooking, and browning them beforehand also seals in lots of flavor.
  • The homemade sauce sure beats a premade jar of sauce with chicken! You’ll be able to taste the difference and will also enjoy it with sides like veggies, rice, or potatoes.

Ingredients Needed 

  • Boneless skinless chicken thighs – Chicken thighs are more fatty than breasts, and the darker meat is very flavorful. Be sure to use boneless thighs since bone-in may cause the meat to overcook and become more shredded – not what we want for this dish. This recipe calls for 2 pounds of thighs, which is typically 3-4 thighs per pound.
  • Olive oil and butter – Melt some olive oil and butter together in the skillet to lightly brown the chicken and seal in flavor.
  • Onion and garlic – Dice half a yellow onion for extra flavor and mince 3 garlic cloves. This combination enhances the chicken and adds complexity to the broth base.
  • Seasonings – Grab a few things from your spice cabinet for a light seasoning. Combine Italian seasoning with just a bit of salt and pepper.
  • Chicken broth – Broth will create the base for the creamy sauce and also keep the thighs juicy in the slow cooker.
  • Grainy mustard – I like using stone ground mustard to add a little texture to the sauce and for a rustic element.
  • Heavy cream – Heavy cream makes the sauce! Don’t make any swaps here – trust me, the richness is so worth it!
  • Lemon juice – Surprisingly, just a bit of lemon juice is enough to give the sauce a tasty, zesty flavor.
  • Cornstarch – Add a little cornstarch to the sauce at the end to thicken it. This ensures it will really stick to the chicken and anything else you want to serve with it.

pro Tips

  • I rarely recommend browning chicken before slow cooking, but definitely brown the thighs in this recipe for added flavor, texture, and overall appearance.
  • Check for doneness with a meat thermometer (165 ℉). 
  • Simmering the sauce is another worthwhile step! It becomes even more rich and thick when it simmers – you won’t get quite the same results by leaving it in the slow cooker.

Recipe Substitutions and Variations

  • I don’t recommend swapping chicken breasts for boneless thighs in this recipe. Chicken breasts won’t deliver the same flavor and texture at the end. However, you could always recreate the sauce and serve it with other cuts of chicken.
  • If you want to try this recipe with another method, I’ve already tested it for you in the Instant Pot! Instant Pot Chicken Thighs with Lemon Sauce will deliver the tastiest results – but faster than the slow cooker!
  • If you don’t have cornstarch on hand, you could always whisk in a bit of all-purpose flour or tapioca flour instead.

What To Serve With Slow Cooker Chicken Thighs

Enjoy a simple, family-friendly meal by serving slow cooker chicken thighs with your favorite veggies and a carb like rice or potatoes. Some of my favorites are roasted broccoli, asparagus, or Sautéed Green Beans with Garlic.

This would also be a delicious choice to serve over buttered penne or egg noodles. If you want to get a bit fancier with your meal, add Slow Cooker Gratin Potatoes and a fresh Caesar salad.

Whatever you serve, you’ll want something to really soak up every bit of the lemon sauce. I recommend including breadsticks or garlic bread just for that reason!

Storing and Reheating

Leftover chicken thighs can be sliced and turned into a delicious lunch over rice and with a side salad. You can also reheat extra sauce to serve over noodles or other veggies. 

Store leftover thighs and sauce in an airtight container in the fridge for up to 3 days. Reheat in the microwave or a skillet on the stove.

Slow Cooker Chicken Thighs FAQs 

  • Do you need liquid in a slow cooker for chicken thighs? For this recipe, you do need to add chicken broth to keep the thighs juicy and to create the sauce base.
  • Is it better to cook chicken thighs on high or low in the slow cooker? For this recipe, you can cook the chicken thighs on either the high or low setting.
  • Why choose chicken thighs over chicken breasts for this recipe? Chicken thighs are the preferred option here because they are so much more flavorful than chicken breasts. With the extra browning step and the juiciness of the dark meat, you really cannot recreate the same results with chicken breasts. The added fat also enhances the already-decadent sauce – you’ll love it!
  • Can chicken thighs be overcooked in the slow cooker? It is possible to overcook chicken thighs if they were left in the slow cooker for a very long time or if the contents dried out. Since these are cooked in chicken broth, the cooking time can be somewhat flexible.
  • Can this recipe be made in the Instant Pot? Yes! See my directions for making chicken thighs with lemon sauce in the Instant Pot

    This was delicious. I made it on the stove, no slow cooker. When I got to the slow cooker part I just cooked the boneless thighs in the brother on low, covered for 20 minutes then did the rest of the receipe as written. As far as being listed on a site as keto, I often save things onto Pinterest boards that say GF or keto , when the recipe as written is not , cause I can make it fit. For instance, leave out the corn starch or sub tapioca starch, and halve the onions and walla it is keto.

    1. Thank you so much! It’s wonderful to hear you enjoyed it. I truly appreciate you taking the time to share your thoughts.

  2. what kind of grainy mustard do you suggest and can you substitute flour for the cornstarch?
    thanks

    I made the recipe as written with the exception of the heavy cream. I had half and half and increased the corn starch to 2 TBL as recommended. The sauce was perfect. I have never prepared chicken thighs. This will not be the last time. The meat was so tender and flavorful. My family said the recipe is a keeper! I’ll be making again soon. Thank you for the recipe. Really delicious!

    So many critics; sounds wonderful to me and look forward to making it this weekend. Love chicken thigs with Busalmic variations. but was searching for something new with a creamy texture. Thanks so much for sharing the recipe!

  5. This recipe also popped up for me on a search for Keto recipes. I’m so glad it did! The only hang-up for me is the cornstarch which is easily substituted with a quick online search. I used bone-in thighs, so I increased the cook time just a bit. So delicious. Thank you!

  6. It is keto apart from the tiny bit of cornstarch, very low carb dinner and looks delicious so I will be making it in my keto diet 🙂

    1. Hi Li! I’m sorry you are frustrated. I’m not sure which keto website included a link to my recipe, but I have no control over what they decide to share. I’m sure you can easily read my post and see here that I have not claimed for this recipe to be Keto as I don’t include any diet specific info on my recipes. I’ve removed your one star rating as I don’t believe it’s fair to penalize my recipe which you haven’t tried because someone else on a site I have no control over claimed it was Keto. I hope you can take it up with that site owner to get your issue resolved and find a recipe that is suitable to your needs!

    I made this for dinner today. It was EXCELLENT!! I made extra sauce so there was lots leftover. We’re going to use it over rotelle pasta and just add some grated provolone cheese to it. I think it’s going to be delicious.
