Ingredients You Need

Chicken

2 large boneless skinless chicken breasts
- Slice them horizontally into cutlets so they cook evenly.
- Use boneless skinless thighs if you prefer darker meat and extra juiciness.
1 teaspoon kosher salt
½ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon smoked paprika or sweet paprika
2 tablespoons olive oil or avocado oil
- Use a neutral oil with a high smoke point so the chicken browns nicely.

Lemon Mustard Sauce

2 tablespoons unsalted butter
- Use plant-based butter if you want a dairy-light version.
3 cloves garlic, minced
1 small shallot, finely minced
- Use 2 tablespoons finely minced yellow onion if you do not have shallots.
1 cup low sodium chicken broth
- Boxed broth works fine; Better Than Bouillon tastes great and saves space.
2 teaspoons Dijon mustard
- Use a smooth Dijon like Maille or Grey Poupon for a classic flavor.
1 teaspoon whole grain mustard (optional, for texture)
Zest of 1 lemon
2–3 tablespoons fresh lemon juice
- Start with 2 tablespoons, then taste and add more if you like extra tang.
¼ cup heavy cream or half-and-half
- Use full-fat coconut milk if you want a dairy-free twist.
1 teaspoon honey or maple syrup
- This balances the acidity; do not skip it unless you avoid all sweeteners.
1 tablespoon chopped fresh parsley
1 teaspoon chopped fresh thyme or ½ teaspoon dried thyme
Extra salt and pepper to taste

Pantry shortcuts

Use pre-minced garlic from a jar if you feel tired; just drain off excess liquid.
Use bottled lemon juice in a pinch, but add lemon zest if possible for brightness.
Use dried parsley and thyme if you do not have fresh herbs; use about one-third the amount.

Equipment List

Large heavy skillet (10 to 12 inch)
- Stainless steel or cast iron browns the chicken best.
Cutting board and sharp knife
Small bowl for seasoning mix
Tongs or a spatula
Microplane or fine grater for lemon zest
Measuring cups and spoons
Whisk or fork for mixing the sauce

Tips & Mistakes

Pat the chicken dry before seasoning so it browns instead of steaming.
Pound or slice chicken into even thickness so it cooks at the same rate.
Season both sides generously; bland chicken tastes sad under a good sauce.
Heat the pan until the oil shimmers before you add chicken so you get a golden crust.
Do not crowd the pan; cook in batches if needed so the chicken sears instead of stews.
Avoid moving the chicken constantly; let it sit a few minutes so a crust forms.
Use medium to medium-high heat; very high heat burns the outside before the inside cooks.
Pull chicken off the heat when it reaches 165°F inside; overcooking dries it out.
Use the brown bits in the pan to build flavor; do not wipe them out before the sauce.
Taste the sauce at the end and adjust salt, pepper, and lemon juice so it hits your preference.
Add cream off the heat or on low so it stays smooth and does not curdle.
Slice chicken against the grain so it stays tender on the plate.

How to Make Pan Seared Chicken with Lemon Mustard Sauce Recipe

Step 1: Prep and season the chicken

Place the chicken breasts on a cutting board and slice them horizontally into 2 thinner cutlets. If they still look thick, cover with plastic wrap and gently pound them to about ½ inch thickness. Pat both sides dry with paper towels so the seasoning sticks.

In a small bowl, mix the salt, pepper, garlic powder, onion powder, and paprika. Sprinkle the seasoning mix evenly on both sides of the chicken and press it in lightly with your fingers. Set the chicken aside while you heat the skillet.

Step 2: Sear the chicken

Heat the olive oil in a large skillet over medium-high heat until it shimmers. Lay the chicken cutlets in the pan in a single layer without overlapping. Cook the first side for about 4 to 5 minutes until the underside looks golden and releases easily from the pan.

Flip the chicken and cook the second side for another 3 to 4 minutes, until the internal temperature reaches 165°F. Adjust the heat down to medium if the outside browns too quickly. Transfer the cooked chicken to a plate and tent it loosely with foil while you make the sauce.

Step 3: Build the flavor base

Turn the heat down to medium. Add the butter to the same skillet and let it melt into the browned bits from the chicken. Stir in the minced shallot and cook for 1 to 2 minutes until it softens and turns slightly translucent.

Add the minced garlic and cook about 30 seconds until it smells fragrant. Scrape the bottom of the pan with a wooden spoon to loosen the browned bits. Those bits carry a ton of flavor into your lemon mustard sauce.

Step 4: Deglaze and simmer the sauce

Pour in the chicken broth while you continue to scrape the bottom of the pan. Add the Dijon mustard and whole grain mustard and whisk or stir until they mix into the broth. Stir in the lemon zest and 2 tablespoons of lemon juice.

Let the mixture simmer for 3 to 4 minutes, until it reduces slightly and thickens a bit. Taste and adjust the acidity with more lemon juice if you want a brighter flavor. If the sauce tastes too sharp, move to the next step and let the cream and honey balance it.

Step 5: Finish the lemon mustard sauce

Turn the heat down to low. Stir in the heavy cream and honey until the sauce looks smooth and silky. Add the thyme and half of the chopped parsley.

Let the sauce simmer gently for 2 to 3 minutes so it thickens to a spoon-coating consistency. Taste again and adjust with more salt, pepper, or lemon juice as needed. If the sauce thickens too much, thin it with a splash of broth.

Step 6: Return chicken to the pan

Add the cooked chicken and any juices from the plate back into the skillet. Spoon the lemon mustard sauce over the top of each piece. Let the chicken simmer in the sauce on low heat for 2 to 3 minutes so the flavors mingle.

Turn off the heat and sprinkle the remaining parsley over the top. Slice the chicken or serve the cutlets whole. Spoon extra sauce over each serving, because that sauce tastes like liquid gold.

Variations I've Tried

Use boneless skinless chicken thighs instead of breasts for a richer, more forgiving version that stays juicy even if you cook it a minute too long. I often use thighs when I meal prep this for lunches. They reheat beautifully and hold the sauce well.

Swap the heavy cream for full-fat coconut milk and use olive oil instead of butter for a dairy-free version. The coconut flavor stays subtle behind the lemon and mustard. I like this version with steamed green beans and jasmine rice.

Add a spoonful of capers to the sauce when you add the lemon zest if you enjoy a briny pop. The salty bite plays nicely with the tangy lemon mustard sauce. I serve that version with roasted potatoes and a simple salad.

Stir in a handful of baby spinach or chopped kale during the last minute of simmering so it wilts into the sauce. This turns the skillet into more of a one-pan meal. My family loves that version over brown rice or quinoa.

How to Serve Pan Seared Chicken with Lemon Mustard Sauce Recipe

Serve the chicken sliced over fluffy white rice, mashed potatoes, or buttered noodles so they soak up the lemon mustard sauce. Add a simple side like roasted broccoli, green beans, or a crisp salad to keep the plate balanced. I also like it with couscous or quinoa when I want a lighter base.

If you cook this for guests, plate the chicken on a platter, spoon sauce over the top, and sprinkle extra herbs for color. Keep a bowl of extra sauce on the table, because someone always asks for more.

How to store

Fridge: Cool leftovers to room temperature, then store chicken and sauce together in an airtight container in the fridge for up to 3 to 4 days.

Reheating on stove: Reheat gently in a covered skillet over low heat with a splash of broth or water until warmed through, about 5 to 8 minutes.
Reheating in microwave: Place chicken and sauce in a microwave-safe dish, cover loosely, and heat in 45 to 60 second bursts at medium power, stirring the sauce and flipping the chicken between bursts.
