Ingredients

  • 4 boneless, skinless chicken breasts pounded to an even thickness
  • 2 teaspoons kosher salt
  • 2 teaspoons black pepper
  • 1 tablespoon olive oil
  • 1 yellow onion finely chopped (about 1/2 cup)
  • 2 cloves garlic grated or finely chopped
  • 3 cups white wine
  • 1/4 cup dijon mustard
  • 2 tablespoons heavy whipping cream
  • 1 tablespoon butter
  • chopped chives for garnish optional

Instructions

  • Heat your cast iron skillet over medium heat.
  • Season the chicken on both sides with salt and pepper.
    4 boneless, skinless chicken breasts, 2 teaspoons kosher salt, 2 teaspoons black pepper
  • Cook the chicken in the cast iron skillet. First, add the olive oil, then cook the chicken about 8 minutes per side, until golden brown and the internal temperature reaches 165º degrees. Transfer the cooked chicken to a plate.
    1 tablespoon olive oil
  • Brown the onions and garlic. In the same skillet, add the choped onions and season with a pinch salt and pepper. Cook for about 4 minutes, scraping up any brown bits at the bottom of the pan while they're cooking for maximum flavor. Add the garlic cloves, and cook just 30 seconds.

  • Make the sauce. Add the white wine, dijon mustard, and stir to combine. Cook until the sauce has reduced by half, will take about 5 minutes. Turn the heat to low, then add the heavy cream and butter. Whisk to combine. Add the chicken back to the skillet to warm thru.
    3 cups white wine, 1/4 cup dijon mustard, 1 tablespoon butter, 2 tablespoons heavy whipping cream
  • Serve the chicken warm, topped with the creamy dijon mustard sauce and chopped chives. I love this on top of white rice, cauliflower rice, mashed potatoes, mashed cauliflower or roasted potatoes.

Notes

Expert Tips

  • Whole30: Use the dairy-free replacements above and chicken stock in place of wine for Whole30.
  • Sweetness: This is also great if you add in a tablespoon of maple syrup. That's how my mom makes it—or monk fruit sweetener if keto.
  • Protein: This creamy mustard chicken recipe is also great with bone-in or boneless chicken thighs. Keep in mind that the cooking time may need to be adjusted. 
  • Wine: I love this with chardonnay or a sauvignon blanc. You could also substitute chicken broth.
  • Dairy Free: Use original flavor Nutpods, coconut cream, or Silk dairy-free heavy cream and then ghee to keep this dairy-free—same quantities for all substitutions.
  • Mustard: I prefer a Dijon mustard, but a spicy brown mustard or grainy mustard would work, too.

Serving Tips

Serve the chicken warm, topped with the creamy Dijon mustard sauce and chopped chives. I love this on top of white rice, cauliflower rice, mashed potatoes, mashed cauliflower, or roasted potatoes. Also, this mustard sauce is so good I put extra on my plate so that I can dip my vegetables in it, too!

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave and serve!
Freeze this mustard chicken recipe in a freezer-safe, airtight container for up to 6 months. You can thaw in the fridge overnight or reheat straight from frozen. Reheat either in the microwave until warm, about 3-5 minutes if thawed, or 6-10 minutes if frozen.
