Slow Cooker French Wine and Mustard Chicken…turning a classic French recipe into an easy slow cooker meal using white wine, creamy Dijon mustard, fresh herbs, and parmesan cheese. And I even added in some vibrant kale for veggies and color. This slow-cooked chicken dinner is a hearty and delicious meal to come home to at the end of a busy day. And the best part? It’s the easiest dinner to prepare. Serve with creamy mashed potatoes, steamed rice, or enjoy over buttery egg noodles. You simply can’t go wrong with a dinner like this French-inspired mustard chicken. Bonus? You can also make this in the Instant Pot or on the stove-top.

Breaking out a slow cooker recipe today and it’s not even October…sorry, but then not really. Because I’m pretty sure that most of us are about ready for a slow cooker recipe. Am I right?

This is one of those dishes that I’ve been wanting to make for the longest time now. But I wanted to hold off until the autumn days started to set in. It’s creamy, herby, a touch buttery, and has the BEST flavor. I never thought I was one to enjoy mustard, but that all changed a few years ago when I made this easy skillet coq au Riesling.

Mustard, when used properly can be such a delicious addition to so many dishes. I’ve yet to learn to love it as more of a dip. But every time fall rolls around I love using mustard to make creamy, savory sauces with fresh herbs.

It’s such a cozy combo with so much flavor. And that’s where this slow cooker chicken comes into play.

Sometime over the summer, I had the idea for this dish. But again I knew this felt like more of a fall recipe. So I wrote it down on our editorial calendar as a recipe to share on this very day. I often do this when I come up with an idea months in advance so I don’t completely forget it. Sometimes I never end up creating the recipe, because when I look at it again, I’m not as excited. But then sometimes I go look at the calendar in prep for cooking days and quickly become excited to finally test out the recipe. That was the case with this chicken. And when I finally tested out the recipe, I was so happy with how it turned out.

What I love so much about this slow cooker chicken is just how easy it is to make.

The first step is to mix up the creamy mustard sauce. It’s a mix of dry white wine, milk, both Dijon mustard and grainy Dijon mustard, shallots, and garlic. Very classic to a French-style cream sauce, and so delicious.

Since I was using a mix of skin on and skin off boneless chicken breasts, I wanted to sear the chicken with fresh thyme and sage before adding it to the slow cooker. Searing skin on chicken not only leaves you with a golden, crisp skin, but the fat that cooks out of the skin while searing really adds so much flavor. You can, of course, skip this step, but I do recommend it if you want extra delicious and flavorful chicken.

Also, my slow cooker does not have a searing function, but if yours does, you can then just sear the chicken right in your slow cooker.

Once the chicken has been seared, add it to the slow cooker along with the creamy mustard sauce. Add a little pat of butter, cover, and cook low and slow until the chicken is extra tender and almost falling apart.

As I mentioned above, I really wanted to incorporate a vegetable into this chicken. I went back and forth between a few different vegetables. But in the end, I settled on kale, adding it in towards the end of cooking. The kale perfectly melts into the sauce and adds just the right amount of flavor and texture.

We all really enjoyed it, but we all love kale over here! You could also use chopped broccoli or cauliflower, which I think would be equally great.

To serve, I love to spoon the chicken and creamy sauce over mashed potatoes or brown rice pilaf. I think mashed cauliflower would be incredibly delicious too. Or go the old school route with buttered egg noodles. Any of these will be so delicious, so take your pick!

And that’s it’s. The simplest dinner, great for any night of the week…hearty, creamy, and so freaking good!

PS. I know my cozy recipes are coming to you a little on the early side. BUT I hope all you planners out there really enjoy this recipe. Never hurts to plan your autumn dinners ahead of time!

Instructions

Slow Cooker

  • 1. In the bowl of your slow cooker, combine the wine, milk/cream, both mustards, shallots, garlic, and a pinch each of salt and pepper.
    2. Rub the chicken with thyme, sage, and a pinch each of salt and pepper. Heat the olive oil in a large skillet over medium high heat. When the oil shimmers, add the chicken and sear until golden brown on both sides, about 3 minutes per side. Remove the chicken from the skillet and place directly into the slow cooker, skin side up, along with any juices left in the skillet. Add the butter.
    3. Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours. During the last 30 minutes of cooking, add the parmesan and kale, gently tossing to combine.
    4. Serve the chicken over mashed potatoes or rice and spoon the creamy mustard sauce over top the chicken. Serve with additional herbs and parmesan.

Instant Pot

  • 1. In a small bowl, combine the wine, milk/cream, both mustards, shallots, garlic, and a pinch each of salt and pepper.
    2. Rub the chicken with thyme, sage, and a pinch each of salt and pepper. Set the Instant Pot to sauté. Add the olive oil. When the oil shimmers, add the chicken and sear until golden brown on both sides, about 3 minutes per side. Pour in the wine/mustard sauce. Add the butter. Cover and cook on high pressure for 8 minutes.
    3. Once done cooking, use the natural or quick release function. Set the Instant pot to sauté and add the parmesan and kale, gently tossing to combine. Cook 5 minutes.
    4. Serve as directed above.

Stove Top

  • 1. In a small bowl, combine the wine, milk/cream, both mustards, and a pinch each of salt and pepper.
    2. Rub the chicken with thyme, sage, and a pinch each of salt and pepper. Heat the olive oil in a large skillet over medium high heat. When the oil shimmers, add the chicken and sear until golden brown on both sides, about 3 minutes per side. Add the shallots and garlic, cook another 3 minutes, until fragrant.
    3. Reduce the heat to low, pour in the wine/mustard sauce. Cover and simmer for 15 minutes, or until the chicken is cooked through. Stir in the parmesan and kale, cooking another 3-5 minutes. If the sauce thickens too much, add additional wine or chicken broth to thin.
    4. Serve as directed above.

    I’ve made this 4+ times. It’s incredible. I always double the recipe and serve with mashed potatoes. Teagan you are the best <3

  2. Looks amazing – I’m obsessed with your recipes and make at least one/week! Although I hate altering recipes – my husband won’t do kale. What would you suggest as a substitute?

    1. Hi Maggie! Spinach should work great as a substitute for the kale. I hope you love this recipe! Please let me know if you have any other questions! xTieghan

  3. This recipe was fantastic the last time i made it! I could only get reduced fat coconut milk delivered – is there anything you recommend to thicken it up?

    1. Hi Kayla,
      So glad you enjoyed the recipe! You could use some heavy cream in place of the coconut milk. Please let me know if you have any other questions! xTieghan

  4. This recipe is soooo out of the ordinary and Delicious!! New staple in my keepers bin!! Thanks so much for sharing it!! ❤️

    My family LOVED this recipe. One of their favorite slow cooker meals – EVER! A nice treat during this “stay at home” time – Thank you 🙂

    1. Hi Molly,
      Yes you can use chicken thighs, keep everything the same-no need to adjust the recipe. Hope it is delish!

  6. Is it possible to do it without cream, butter and parmesan? And maybe in the oven? Or do you have a recipe for a chicken with a mustard marinade, cooked in the oven (avoiding cream etc, but OK adding beer or wine)? Thanks!

    1. HI there! You can roast this on the oven, but you do need the cream at least. Can you canned coconut milk? If so, that would work great!! You can leave out the butter and use olive oil and them just omit the parmesan completely. Please let me know if you have any other questions. I hope you love this recipe! Thank you!! xTieghan

    I made this after getting an email from you about pantry recipes to make during quarantine. It looked different from recipes I usually make, with some new flavors (mustard) – and we had most ingredients on hand. What a wonderful surprise this recipe was! I made it in the instant pot (we are huge instant pot fans), and substituted dried herbs for the fresh ones, as well as tiny potatoes, boiled – in lieu of mashed. Everything in this recipe just works so well together, and it feels fancy! I cook a lot – and I have a new years resolution of trying one new recipe a week. It’s pretty cut-throat competition to make it into my binder of keeper recipes – but this was my husbands favorite recipe this year. Thank you so much for the wonderful recipe and quarantine entertainment. We hope you and your family are staying safe and healthy!

    1. Hi Jenny! I am so glad you decided to try this and am so glad it turned out so well for you! Thank you! xTieghan

    This recipe is fantastic!!! Thanks SO much!! Even the picky eaters have asked for an encore of this dish a week later!

  9. I love your recipes and appreciate all your hard work. I do have a question. We have a family member who is successfully maintaining sobriety so I need to avoid all alcohol in cooking such as wine and beer. Do you have a suggestion as to how I can handle this but still prepare your recipes with alcohol in the ingredient list. Thanks

    1. Hi Marla! I am so glad you asked and of course you can sub! For the wine, it will be 1 part cranberry juice, 1 part pomegranate and 1 part water! I hope you enjoy this recipe! xTieghan

    Good morning Tieghan,
    I made this last night and couldn’t wait to write a review. If I could, I would rate this a 10!!!!! IT WAS DELICIOUS!!! I used my instant pot and it turned out freakin’ good! I didn’t have grainy mustard so I used 3 TBS. of Dijon, coconut milk and 1/2 of a small onion finely diced as I didn’t have any shallots on hand and everything else as you stated. Oh, I forgot, as I was rereading the recipe after to add the make of wine I used and the substitutions I used, I read it called for 2 lbs. of chicken and I used 2 whole chicken breasts!!! It was still delicious. The creamy sauce is to die for!
    Thank you for all your wonderful recipes, your beautifully designed site and being such an inspiration to cook—I haven’t made one of your recipes that I don’t put DELISH on top before I file it away.
    Thank you again!
    Susan

    1. Aw this is so amazing to read! I am so glad this recipe turned out so well for you and I hope you continue to love others of mine! Thank you Susan! Have a great week! xTieghan

    Amazing, I can’t stop thinking about it. I made this tonight- the stovetop version. I didn’t see where to put the butter in on the instructions so I removed the seared chicken, cooked the shallots and garlic with the butter. Then added the chicken and juices back in. It was incredible! Another successful recipe Tieghan!

    This was amazing! I made it in the instant pot and the chicken was so tender it basically fell apart. So much good flavor. I replaced the kale with spinach as well.

    1. Hey Shannon, Dutch oven directions are listed right below the slow cooker directions. Please let me know if you have any other questions. I hope you love this recipe! Thank you!! xTieghan
