Ingredients You Need

Chicken

4 small boneless skinless chicken breasts
- Or use 2 large breasts sliced in half horizontally into cutlets
- You can also use boneless skinless thighs for 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

For Searing

2 tablespoons olive oil
1 tablespoon butter
- I like Kerrygold or any good quality unsalted butter
Optional: 1 tablespoon neutral oil if your pan runs very hot

Lemon Mustard Sauce

3 cloves garlic, minced
1 small shallot, finely minced
- Red onion works in a pinch, just mince it very fine
½ cup low sodium chicken broth
- Use homemade if you have it, or a good boxed brand like Swanson or Kettle & Fire
⅓ cup heavy cream
- Half and half works, though the sauce turns slightly thinner
2 tablespoons Dijon mustard
- I like Maille or Grey Poupon for a smooth, balanced flavor
1 tablespoon whole grain mustard
- Optional, but it adds nice pops of texture
Zest of 1 lemon
3 tablespoons fresh lemon juice
1 teaspoon honey or maple syrup
- This softens the sharpness of the mustard and lemon
1 tablespoon butter, cold, to finish the sauce
2 tablespoons chopped fresh parsley
- Basil or chives also taste great

Pantry Shortcuts & Substitutions

Use pre-minced garlic from a jar if you need speed, just reduce slightly since it tastes stronger.
Use bottled lemon juice if you must, but still try to use fresh zest from at least half a lemon.
If you do not keep heavy cream, whisk 1 teaspoon cornstarch into ⅓ cup milk and add that instead.

Equipment List

Large heavy skillet, 10 to 12 inches
- Cast iron or stainless steel browns the chicken best
Tongs for flipping the chicken
Small whisk or fork for the sauce
Microplane or fine grater for lemon zest
Instant read thermometer for perfect doneness

Quick Tips & substitutions

Pat the chicken dry so it browns instead of steaming.
Pound thicker pieces to an even thickness so they cook evenly.
Season the chicken generously on both sides, since the seasoning forms the flavor base.
Heat the pan until the oil shimmers before you add the chicken.
Do not crowd the pan, or the chicken will not brown well.
Use chicken thighs if you want extra forgiveness and juiciness.
Swap Dijon with stone ground mustard if you like a bit more texture.
Use Greek yogurt instead of cream for a lighter sauce, but stir it in off the heat.
Replace chicken broth with vegetable broth if that is what you have.
Add a pinch of red pepper flakes if you like a little heat.

How to Make Pan Seared Chicken with zesty Lemon Mustard Sauce

Step 1: Prep and season the chicken

Lay the chicken breasts on a cutting board and pat them very dry with paper towels. If they look thick on one side, cover them with plastic wrap and gently pound them with a rolling pin or skillet until they reach an even ½ to ¾ inch thickness. Season both sides with salt, pepper, garlic powder, onion powder, and paprika, then let the chicken sit while you prep the sauce ingredients.

Step 2: Sear the chicken

Heat a large skillet over medium high heat and add the olive oil and 1 tablespoon butter. When the fat looks hot and shimmery and a tiny piece of chicken sizzles on contact, lay the chicken in the pan in a single layer. Cook the chicken without moving it for 4 to 5 minutes until the underside turns deep golden and releases easily from the pan.

Flip the chicken and cook another 3 to 5 minutes, depending on thickness, until the internal temperature reaches 165°F. If the chicken browns too quickly, lower the heat to medium. Transfer the cooked chicken to a plate and tent it loosely with foil while you make the lemon mustard sauce.

Step 3: Build flavor in the pan

Turn the heat down to medium. If the pan looks very dry, add a small splash of oil or a tiny knob of butter. Add the minced shallot and cook 1 to 2 minutes, stirring, until it softens and picks up some of the browned bits.

Add the garlic and cook about 30 seconds until it smells fragrant, not burnt. Scrape up any browned bits from the bottom of the pan with a wooden spoon, since those bits carry a ton of flavor. If anything starts to scorch, lower the heat and move things around quickly.

Step 4: Deglaze and simmer the sauce

Pour in the chicken broth and stir well, scraping the bottom of the pan to loosen all the browned bits. Let the broth simmer for 2 to 3 minutes until it reduces slightly and tastes more concentrated. Whisk in the Dijon mustard, whole grain mustard, lemon zest, and lemon juice until the sauce looks smooth.

Stir in the honey and taste, then adjust with a little more lemon juice, salt, or honey until the flavor hits that sweet spot between tangy and creamy. Pour in the heavy cream and stir again. Let the sauce bubble gently for 2 to 3 minutes until it thickens enough to lightly coat the back of a spoon.

Step 5: Finish the sauce with butter and herbs

Turn the heat to low. Add the cold tablespoon of butter and whisk until it melts into the sauce and turns glossy. Stir in the chopped parsley and taste again for seasoning.

If the sauce tastes too strong, splash in a bit more broth or cream. If it tastes too mild, add a small squeeze of lemon or a tiny spoon of Dijon. Keep the sauce at a gentle simmer, not a hard boil, so it stays silky.

Step 6: Return the 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 for 2 to 3 minutes so it soaks up the flavor and warms through.

Check one piece with a thermometer or cut into the thickest part to confirm it reaches 165°F. Turn off the heat and sprinkle a little extra parsley or lemon zest on top if you like a bright finish. Serve the chicken with plenty of sauce over your favorite side.

Storage Success

Let the chicken and sauce cool until they reach room temperature, then store them together in an airtight container. Keep the container in the fridge for up to 3 to 4 days. Reheat gently on the stove over low heat with a splash of broth or water so the sauce loosens and the chicken stays tender. You can also freeze portions for up to 2 months, then thaw overnight in the fridge and reheat slowly.
