Ingredients You’ll Need

Chicken

4 small boneless, skinless chicken breasts
- Aim for about 5 to 6 ounces each.
- If they look thick, slice them horizontally into cutlets so they cook evenly.
1 ½ teaspoons kosher salt
¾ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon smoked paprika or sweet paprika
2 tablespoons all-purpose flour
- This light coating helps browning and thickens the sauce slightly.
- Use a 1:1 gluten free blend if you avoid regular flour.

For Searing

2 tablespoons olive oil
- Use a regular or “classic” olive oil, not extra virgin, since it handles higher heat better.
1 tablespoon unsalted butter
- Butter adds flavor and helps browning.

Lemon Mustard Sauce

3 cloves garlic, minced
1 cup low sodium chicken broth
- Boxed broth works well; I like Kitchen Basics or Pacific.
- Use water plus ½ teaspoon chicken bouillon paste in a pinch.
2 tablespoons Dijon mustard
- Dijon gives a smooth, sharp flavor; I like Maille or Grey Poupon.
1 tablespoon whole grain mustard
- Adds texture and deeper flavor; if you do not have it, add 1 extra teaspoon Dijon.
Zest of 1 lemon
Juice of 1 large lemon (about 3 tablespoons)
¼ cup heavy cream
- Use half-and-half if you want a lighter sauce, and simmer a bit longer to thicken.
1 teaspoon honey or sugar
- This tiny bit balances the acidity without making the sauce sweet.
2 tablespoons unsalted butter, cold and cut into small cubes
2 tablespoons chopped fresh parsley
- Use dried parsley if needed; use 2 teaspoons and add earlier in the simmer.

Optional Add-ins

1 teaspoon capers, drained, for a briny kick
Pinch of red pepper flakes for gentle heat

Equipment

Large heavy skillet (10 to 12 inch; cast iron or stainless steel works best)
Tongs
Small whisk
Microplane or fine grater for lemon zest
Instant read thermometer (helps you avoid dry chicken)

Tips & Tricks

Pat the chicken very dry with paper towels so it browns instead of steaming.
Pound thicker parts of the chicken to an even thickness so everything cooks at the same speed.
Season the chicken generously; bland chicken never tastes better under sauce.
Preheat the skillet until a drop of water sizzles and evaporates quickly.
Do not crowd the pan; cook the chicken in batches if needed so each piece browns nicely.
Leave the chicken alone while it sears; constant flipping prevents a good crust.
Use medium high heat for searing, then lower the heat when you build the sauce so it does not scorch.
Scrape up the browned bits from the skillet when you add broth; those bits carry huge flavor.
Taste the sauce at the end and adjust salt, lemon, and mustard so it matches your preference.
Add the cold butter at the end off the heat so the sauce stays silky and does not break.

How to Make Pan Seared Chicken with zesty Lemon Mustard Sauce

Step 1: Prep the Chicken

Lay the chicken breasts on a cutting board and trim any excess fat. If they look thick, slice them horizontally into thinner cutlets. Cover with plastic wrap and lightly pound the thicker ends with a meat mallet or rolling pin until each piece has an even thickness.

In a small bowl, mix the salt, pepper, garlic powder, onion powder, and paprika. Pat the chicken dry, then sprinkle the seasoning mix evenly on both sides. Dust each piece lightly with flour and shake off any extra so you only see a thin coating.

Step 2: Sear the Chicken

Heat the olive oil in your skillet over medium high heat until it shimmers. Add the 1 tablespoon of butter and swirl the pan until it melts and foams. Place the chicken in the skillet in a single layer, seasoned side down.

Sear the chicken for 4 to 5 minutes on the first side without moving it until the underside turns deep golden brown. Flip and cook another 3 to 5 minutes, depending on thickness, until the internal temperature reaches 165°F. Move the cooked chicken to a plate and tent it loosely with foil while you make the sauce.

Step 3: Build the Lemon Mustard Base

Lower the heat to medium. If the skillet looks very dry, add another teaspoon of olive oil. Add the minced garlic and stir constantly for about 30 seconds until it smells fragrant.

Pour in the chicken broth and use a wooden spoon to scrape up all the browned bits from the bottom of the pan. Add the Dijon mustard, whole grain mustard, lemon zest, and lemon juice. Whisk until the mustards dissolve into the liquid and no clumps remain.

Step 4: Simmer and Add Cream

Bring the sauce to a gentle simmer and let it bubble for 3 to 4 minutes. The liquid should reduce slightly and start to look a bit thicker. Stir in the heavy cream and honey.

Let the sauce simmer another 2 to 3 minutes, stirring now and then, until it coats the back of a spoon. Taste and add a pinch of salt or more lemon juice if you want extra brightness. Add the red pepper flakes and capers now if you use them.

Step 5: Finish the Sauce with Butter

Turn the heat to low or remove the skillet from the burner. Add the cold butter cubes a few at a time, whisking constantly until each piece melts into the sauce. This step gives the sauce a glossy finish and richer flavor.

Stir in the chopped parsley. The sauce should look smooth and slightly thick, not runny like broth. If it looks too thick, splash in a tablespoon or two of broth and whisk again.

Step 6: Return the Chicken to the Skillet

Place the seared chicken and any juices from the plate back into the skillet. Spoon the sauce over the top of each piece so they all get a good coating. Let the chicken simmer in the sauce over low heat for 2 to 3 minutes.

Check one piece to make sure it still feels juicy and hot in the center. Turn off the heat and squeeze a little extra lemon over the top if you like bold citrus flavor. Sprinkle on a bit more parsley for color and freshness.

Step 7: Serve

Serve the Pan Seared Chicken with zesty Lemon Mustard Sauce straight from the skillet while it stays hot and glossy. Spoon extra sauce over each plate because everyone always wants more. If you cook for kids or spice sensitive eaters, keep the red pepper flakes on the side so people can add their own heat.

What to Serve with Pan Seared Chicken with zesty Lemon Mustard Sauce

This chicken pairs beautifully with fluffy white rice, buttery mashed potatoes, or simple buttered noodles that soak up the lemon mustard sauce. You can also spoon it over quinoa or cauliflower rice if you want a lighter base. Add a crisp green salad, roasted broccoli, or green beans with a squeeze of lemon to echo the bright flavors.

Serve it with sparkling water flavored with lemon or lime, or a cold glass of iced tea for a refreshing contrast. If you cook this for guests, add a simple fruit salad or sliced berries on the side to finish the meal without extra effort.

Storage Options

Store leftover chicken and sauce together 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 until the chicken warms through and the sauce loosens.
You can freeze the cooked chicken with sauce for up to 2 months, though the cream may change texture slightly.
Thaw overnight in the fridge, then reheat slowly on the stove and whisk in a spoonful of fresh cream to bring the sauce back to a smooth texture.
