- 1 tablespoon olive or avocado oil: Provides the perfect base to sear the chicken, adding subtle richness.
- 1½ pounds chicken breasts, boneless and skinless, cut into 1-inch pieces: Tender chicken pieces that soak up the creamy mustard sauce beautifully; thighs work well too if you prefer extra juiciness.
- ½ teaspoon salt: Enhances the natural flavors of the chicken and sauce.
- ½ teaspoon chili powder: Adds a gentle, smoky warmth without overpowering the dish.
- ½ teaspoon ground mustard: Boosts the mustard flavor with a ground spice kick.
- ½ teaspoon garlic powder: Infuses savory depth throughout the sauce and chicken.
- ½ teaspoon dried parsley: Introduces a hint of herbaceous brightness to the mix.
- 5 ounces fresh baby spinach: Adds vibrant color and a subtle earthy note while providing nutritious greens.
- ½ cup coconut aminos: A naturally sweet and savory sauce that gives the dish a unique umami richness without soy.
- ½ cup water: Helps create the sauce’s perfect consistency.
- 1½ tablespoons Dijon mustard: The star ingredient that brings tangy creaminess and sharpness.
- 1 teaspoon balsamic vinegar: Adds a touch of acidity to balance the creaminess and deepen flavors.
- ¼ teaspoon salt: A pinch added into the sauce for seasoning harmony.
- 1 tablespoon arrowroot flour: Used as a natural thickening agent to give the sauce its perfect silky texture.
- 1 tablespoon cold water: Mixed with arrowroot to prevent lumps.
- Sesame seeds: A nutty garnish adding a little crunch and visual appeal.
- Fresh chopped parsley: For a fresh, herbaceous finish that brightens every bite.
How to Make Creamy Mustard Skillet Chicken Recipe
Step 1: Prepare the Chicken
Start by heating your oil in a large skillet over medium-high heat. Season the chicken pieces with salt, chili powder, ground mustard, garlic powder, and dried parsley. Sear them in the hot oil until they’re golden brown on the outside and almost cooked through. This step locks in juiciness and sets the foundation for the sauce.
Step 2: Wilt the Spinach
Once the chicken is nicely browned, add the fresh baby spinach directly to the skillet. Stir it around for a minute or two until the spinach wilts and becomes tender. This step brightens the dish visually and adds a fresh, green component to the creamy sauce.
Step 3: Create the Sauce
In a small bowl, whisk together the coconut aminos, water, Dijon mustard, balsamic vinegar, and the extra pinch of salt. Pour this mixture into the skillet with the chicken and spinach, letting it heat through gently to marry all those wonderful flavors.
Step 4: Thicken the Sauce
Mix the arrowroot flour with cold water until smooth, then stir this slurry into the skillet. Keep stirring as the sauce thickens; this ensures silky texture coats every piece of chicken perfectly without clumps.
Step 5: Final Touches
Once the sauce reaches a luscious creaminess and the chicken is fully cooked through, turn off the heat. Sprinkle sesame seeds and fresh chopped parsley on top for a nutty crunch and a burst of color that makes the dish irresistible.
