Ingredients You Need

Chicken

4 small boneless skinless chicken breasts
- Pound them to even thickness so they cook evenly.
- Use thighs if you prefer darker meat and extra juiciness.
1 teaspoon kosher salt
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1/2 teaspoon smoked paprika or sweet paprika

For searing

2 tablespoons olive oil
- Use avocado oil if you like a higher smoke point.
1 tablespoon butter
- Salted or unsalted both work; adjust salt to taste.

Lemon mustard sauce

3 cloves garlic, minced
1 cup low sodium chicken broth
- Use good quality boxed broth; I like Kitchen Basics or Pacific.
1/3 cup heavy cream
- Use half and half for a lighter version, or full fat coconut milk for dairy free.
2 tablespoons Dijon mustard
- Choose a smooth Dijon; whole grain can add texture if you enjoy that.
1 tablespoon whole grain mustard (optional, for extra texture and flavor)
Zest of 1 lemon
3 tablespoons fresh lemon juice
1 teaspoon honey or maple syrup
- This balances the acidity without making the sauce sweet.
1 tablespoon chopped fresh parsley or chives
Extra salt and pepper to taste

Optional add-ins

1/4 teaspoon red pepper flakes for gentle heat
1/4 cup grated Parmesan for extra richness

Equipment

Large heavy skillet (cast iron or stainless steel works best)
Tongs
Small whisk or fork
Cutting board and sharp knife
Meat mallet or rolling pin to pound chicken
Microplane or fine grater for lemon zest

Quick Tips & substitutions

Pound chicken to about 1/2 inch thickness so it cooks evenly and stays juicy.
Pat chicken dry before seasoning so you get better browning in the pan.
Use thighs instead of breasts if you want extra forgiving, ultra juicy meat.
Swap heavy cream with half and half or full fat coconut milk for dairy free.
Use grainy mustard only for part of the mustard so the sauce stays smooth.
Add a pinch of sugar if your lemon tastes very sharp and the sauce feels too tart.
Use a nonstick skillet if stainless steel scares you, but cast iron gives the best crust.
Double the sauce if you plan to serve with pasta or rice and want extra spooning potential.

How to Make Pan Seared Chicken with Lemon Mustard Sauce Recipe

Prep the chicken

Season both sides of the chicken with salt, pepper, garlic powder, onion powder, and paprika. Press the seasoning into the meat so it sticks well. Let the chicken sit at room temperature for about 10 to 15 minutes while you prep the sauce ingredients.

Zest the lemon first, then juice it, and set both aside. Mince the garlic and chop the herbs so you can move quickly once the chicken sears. Keep the broth, cream, and mustards near the stove.

Sear the chicken

Heat the olive oil in a large skillet over medium high heat until it shimmers. Add the chicken in a single layer and do not move it for 4 to 6 minutes, until the underside turns deep golden brown. Flip the chicken and add the butter to the pan.

Tilt the pan slightly and spoon the melted butter over the chicken for extra flavor. Cook another 3 to 5 minutes, depending on thickness, until the internal temperature hits 165°F. Transfer the chicken to a plate and tent loosely with foil to keep it warm.

Build flavor in the pan

Turn the heat down to medium. Add the minced garlic to the skillet and stir for about 30 seconds until it smells fragrant and just turns lightly golden. Scrape up the browned bits from the bottom of the pan with a wooden spoon.

Pour in the chicken broth and whisk to combine with the garlic and pan drippings. Let the mixture simmer for 2 to 3 minutes so it reduces slightly and concentrates in flavor. Keep the heat at a gentle bubble, not a wild boil.

Make the lemon mustard sauce

Whisk in the Dijon mustard, optional whole grain mustard, lemon zest, and lemon juice. Add the honey and taste; adjust with a little more honey if the sauce feels too sharp for your liking. Let the sauce simmer for another 2 minutes so the flavors blend.

Stir in the heavy cream and keep whisking until the sauce turns smooth and silky. Let it gently simmer for 2 to 3 minutes until it thickens enough to coat the back of a spoon. Add salt and pepper to taste, and stir in red pepper flakes if you want a bit of heat.

Finish the chicken in the sauce

Return the chicken and any accumulated juices to the skillet. Spoon the lemon mustard sauce over the chicken so each piece gets coated. Let the chicken simmer in the sauce for 2 to 3 minutes so it soaks up more flavor.

Sprinkle chopped parsley or chives over the top. Add Parmesan at this point if you want a slightly cheesy, richer sauce and stir until it melts in. Turn off the heat and let the pan sit for 1 to 2 minutes so the sauce settles and thickens slightly more.

Serve

Slice the chicken or serve the pieces whole. Spoon plenty of lemon mustard sauce over each serving. Garnish with extra herbs and a small wedge of lemon on the side if you like a stronger citrus kick.

Recipe Variations

Gluten free: Use gluten free chicken broth and serve with rice, mashed potatoes, or polenta.
Dairy free: Swap butter with more olive oil and use full fat coconut milk instead of cream.
Low carb: Serve with cauliflower rice, zucchini noodles, or roasted broccoli.
Extra herby: Add fresh thyme or rosemary while the sauce simmers, then remove stems before serving.
Spicy version: Add more red pepper flakes or a dash of hot sauce to the sauce.
Veggie boost: Sear chicken, then cook sliced mushrooms or green beans in the same pan before you add broth.

Ways to Serve

Spoon over fluffy white rice, brown rice, or quinoa.
Serve with mashed potatoes or garlic mashed cauliflower.
Pair with roasted vegetables like broccoli, carrots, or asparagus.
Serve with a simple green salad and crusty bread to soak up the lemon mustard sauce.
Toss cooked pasta in the sauce and slice the chicken over the top.

Storage Success

Store leftover chicken and lemon mustard sauce in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over low heat with a splash of broth or water so the sauce loosens and the chicken stays tender. You can freeze the cooked chicken with sauce for up to 2 months, though the texture of the cream may change slightly. Stir the sauce well after thawing and reheating, and it will still taste great over rice or veggies.
