Pan Seared Chicken Breasts with Lemon Mustard Sauce Recipe
Introduction
This pan-seared chicken breast recipe is quick, flavorful, and perfect for a weeknight dinner. The lemon mustard sauce adds a bright, tangy touch that complements the tender chicken beautifully. You’ll have a satisfying meal ready in no time.

Ingredients
- 3 chicken breasts (skinless, boneless)
- 1 cup chicken broth (or chicken stock, or water + chicken base)
- 5 cloves garlic
- 1 tablespoon lemon juice (freshly squeezed)
- 1 tablespoon Italian seasoning (start with half and adjust to taste)
- 1 tablespoon Dijon mustard
- 1 tablespoon arrowroot starch (or potato starch, all-purpose flour, or cornstarch if not on Whole30)
- 1 tablespoon water
- 2 tablespoons avocado oil
- Salt
- Black pepper
Instructions
- Step 1: Pat the chicken breasts dry with a paper towel. Score each piece with a crosshatch pattern by making two cuts lengthwise and five cuts crosswise without cutting all the way through. Season both sides with salt and black pepper.
- Step 2: Heat avocado oil in a large skillet over medium-high heat. Add the chicken breasts and whole garlic cloves to the hot oil. Cook the chicken for about 5 minutes on each side until golden brown.
- Step 3: Carefully pour in the chicken broth, then stir in Italian seasoning, Dijon mustard, and lemon juice. Continue cooking for a few minutes until the chicken reaches an internal temperature of 165°F (74°C).
- Step 4: In a small bowl, whisk together the arrowroot starch and water to create a slurry. Move the chicken to one side of the pan, then slowly add the slurry while stirring the sauce on medium heat. Cook for one more minute to thicken the sauce.
- Step 5: Serve the chicken breasts topped with the lemon Dijon sauce immediately for best flavor.
Tips & Variations
- If you prefer, substitute avocado oil with olive oil or another neutral oil suitable for searing.
- Adjust the amount of Italian seasoning gradually, especially if your blend is very strong.
- For a creamier sauce, stir in a splash of heavy cream or coconut milk after thickening.
- Use a meat thermometer to ensure the chicken is perfectly cooked without drying out.
Storage
Allow leftover chicken to cool to room temperature before storing. Place in an airtight container and refrigerate for up to 3 days. Reheat gently in a skillet over low heat to preserve moisture and avoid overcooking the chicken.

- Total Time: 25 minutes
- Yield: 3 servings 1x
Description
This Pan Seared Chicken Breasts with Lemon Mustard Sauce recipe features juicy, golden-brown chicken breasts cooked in a flavorful skillet sauce made from garlic, chicken broth, Dijon mustard, lemon juice, and Italian seasoning. The chicken is scored to enhance tenderness and absorb the tangy, aromatic sauce, making it an easy and elegant meal perfect for any day of the week.
Ingredients
Chicken
- 3 skinless, boneless chicken breasts
- Salt, to taste
- Black pepper, to taste
Sauce
- 1 cup chicken broth (or chicken stock or water + chicken base)
- 5 cloves garlic
- 1 tablespoon freshly squeezed lemon juice
- 1 tablespoon Italian seasoning (start with half, adjust to taste)
- 1 tablespoon Dijon mustard
- 1 tablespoon arrowroot starch (or potato starch, all-purpose flour, or cornstarch)
- 1 tablespoon water
- 2 tablespoons avocado oil
Instructions
- Prepare the Chicken: Pat the chicken breasts dry with a paper towel. Score each piece by making two cuts lengthwise and five cuts across the breast, creating a crosshatch pattern without cutting through the meat. Season both sides generously with salt and black pepper.
- Heat the Oil and Sear Chicken: In a large skillet over medium-high heat, heat the avocado oil. Add the chicken breasts and whole garlic cloves to the hot oil. Cook the chicken for about 5 minutes on each side until the surface is golden brown and nicely seared.
- Add Sauce Ingredients and Simmer: Carefully pour in the chicken broth and stir in the Italian seasoning, Dijon mustard, and lemon juice. Continue cooking the chicken in the sauce for a few more minutes, ensuring the internal temperature reaches 165°F (74°C). Cooking time will depend on chicken thickness.
- Thicken the Sauce: In a small bowl, whisk together the arrowroot starch and water to create a slurry. Move the chicken pieces to one side of the skillet, and slowly pour the starch slurry into the pan over medium heat while stirring continuously. Cook for about 1 minute until the sauce thickens.
- Serve: Spoon the lemon-Dijon pan sauce over the chicken breasts and serve immediately. For leftovers, let the chicken cool to room temperature before storing it in an airtight container in the refrigerator.
Notes
- Scoring the chicken helps the flavors penetrate and improves tenderness.
- You can substitute arrowroot starch with potato starch, all-purpose flour, or cornstarch if not following Whole30.
- Adjust Italian seasoning according to taste; some blends are stronger than others.
- Ensure chicken reaches an internal temperature of 165°F (74°C) to guarantee it is cooked safely.
- Serve with your choice of sides such as steamed vegetables, rice, or a fresh salad.
