Easy Creamy Mustard Chicken For One

Easy Creamy Mustard Chicken Recipe - a single serving version of a classic French dish. One chicken breast (or thigh) cooked in a velvety smooth and creamy mustard tarragon sauce. The ideal amount for anyone cooking for one. Serve over rice or pasta.

When my kids were small, I would often make this creamy mustard chicken recipe for dinner. The flavor of the chicken with a mustard tarragon sauce is spectacular and my family loved the big chunks of chicken smothered with sauce served over a plate of pasta.

I loved the fact that this dish came together quickly, tasted gourmet and was fairly inexpensive to put on the table. It's a meal that was perfect for a busy weeknight but also beautiful enough to serve guests.

I've taken the same low carb Chicken With Mustard Sauce that I've been making for so many years for my large family and scaled it down to serve one person.

This chicken recipe has the same wonderful ingredients found in the original version but now it's the perfect amount for one.

See recipe box below for ingredient amounts and full recipe instructions.

  • butter
  • 1 boneless, skinless chicken breast
  • salt & pepper
  • heavy cream (also known as double cream)
  • dijon mustard
  • dried tarragon

How To Make Mustard Chicken

  1. Start by cutting one chicken breast into cubes. Heat a little butter in a skillet and add the chicken to the pan. Cook the chicken, then transfer the chicken pieces to a plate.
  2. Add cream to the same pan along with a teaspoon of dijon mustard and 1/2 teaspoon of dried tarragon. Stir the sauce for a few minutes until it begins to thicken. Add the chicken back to the pan and stir to coat all of the chicken with the sauce.
  3. Serve the chicken with mustard tarragon sauce with rice or over pasta.

Dijon mustard and tarragon go so well together and the velvety smooth sauce is ideal with chicken. I've even used the mustard tarragon sauce with salmon and shrimp as well.

Low Carb and Keto Diet

If you're following the keto diet, this mustard chicken needs to be on your menu. Instead of serving it with rice or pasta, try serving it with a delightful cauliflower mash.

  1. Is there something that can be used in this other than heavy cream? Seems to add a lot of fat to the dish and I am trying to loose weight.

    1. Hi Marilyn,
      You could use lowfat milk instead if you would like. As the sauce simmers, the cream causes the sauce to thicken a bit. Using lower fat milk would still be delicious but the sauce will not be as thick.


  2. Wow. I just found your site a few days ago. I tried the Baked Chicken Caprese which was delicious. Tonight I fixed the Easy Creamy Mustard Chicken. I’ve never had tarragon before so I wasn’t sure but it turned out fabulously and its definitely going to be one of my go to meals.

    1. Hi Sonia,
      I’m so happy you found our website and are enjoying the recipes. Thank you so much for taking the time to let me know.

      Have a wonderful week!

    1. Hi Tillia,

      I’ve never tried making this dish in a slow cooker so I can’t tell you if it would work the same. However, if you decide to try it, I would cook the chicken in the slow cooker with a little salt and pepper and add in a cup or so of chicken broth (I’m assuming you are using a 1.5 to 2-quart slow cooker). After the chicken has cooked, remove the chicken briefly from the slow cooker and whisk in the cream, mustard, and tarragon. Then put the chicken back into the sauce to cook until the sauce has thickened, about 20 minutes. Be sure to add additional salt and pepper if necessary.
