Ingredients You’ll Need
Chicken and Pan Sauce
- 4 boneless skinless chicken breasts
- Use thighs if you prefer richer flavor and extra tenderness.
- 1 ½ teaspoons kosher salt
- ¾ teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried Italian seasoning or dried thyme and oregano mix
- 2 tablespoons olive oil
- 2 tablespoons butter (salted or unsalted both work; adjust salt if needed)
- 4 large garlic cloves, minced or pressed
- ½ cup chicken broth or stock
- Use low sodium if you want more control over seasoning.
- ¼ cup heavy cream
- 1 teaspoon Dijon mustard
- 2 tablespoons chopped fresh parsley
- 1 tablespoon chopped fresh thyme or rosemary
- Use 1 teaspoon dried herbs if you do not have fresh ones.
- Juice of ½ lemon
Creamy Mashed Potatoes
- 2 pounds Yukon Gold potatoes, peeled and cut into chunks
- Use Russet potatoes for extra fluffy texture; keep Yukon for creamier texture.
- 1 tablespoon kosher salt for the boiling water
- 4 tablespoons butter, cut into pieces
- ½ to ¾ cup warm milk or half-and-half
- Use whole milk for best flavor; oat milk works in a pinch.
- ¼ cup sour cream or plain Greek yogurt
- ½ teaspoon garlic powder
- ½ teaspoon salt, plus more to taste
- ¼ teaspoon black pepper
Pantry Shortcuts and Substitutions
- Use pre-minced garlic from a jar if you feel short on time, but fresh garlic gives better flavor.
- Use dried parsley and thyme if you do not have fresh herbs, but cut the amount in half because dried herbs taste stronger.
- Use rotisserie chicken in a pinch; just warm it in the pan sauce and focus your effort on the creamy mashed potatoes.
Equipment List
- Large skillet (preferably stainless steel or cast iron) for browning chicken
- Medium or large pot for boiling potatoes
- Colander for draining potatoes
- Potato masher or hand mixer
- Cutting board and sharp knife
- Measuring cups and spoons
- Wooden spoon or silicone spatula
Tips & Tricks
- Pat the chicken dry with paper towels so it browns well and does not steam.
- Pound thicker chicken breasts to an even thickness so they cook evenly and stay juicy.
- Season the chicken generously on both sides; bland chicken ruins a great pan sauce.
- Use medium heat for browning; high heat burns the garlic and scorches the pan.
- Warm the milk and butter before you add them to the potatoes so they absorb better and stay smooth.
- Add the liquid to the mashed potatoes gradually so you control the texture and avoid soupy potatoes.
- Taste the potatoes and sauce at the end and adjust salt, pepper, and lemon juice so the flavors pop.
- Let the chicken rest for 5 minutes before slicing so the juices stay inside the meat.
How to Make Garlic Herb Chicken with Creamy Mashed Potatoes
Step 1: Season the chicken
Lay the chicken breasts on a cutting board and pat them dry on both sides. Sprinkle them with salt, pepper, garlic powder, onion powder, and dried Italian seasoning. Press the seasonings into the meat so they stick well and coat the chicken evenly.
Step 2: Brown the chicken
Heat olive oil in a large skillet over medium heat. Add the chicken in a single layer and leave a little space between each piece so they brown instead of steam. Cook 5 to 7 minutes per side until the chicken turns deep golden and the center reaches 165°F, then transfer the chicken to a plate and cover it loosely with foil.
Step 3: Start the potatoes
While the chicken browns, place the potato chunks in a large pot and cover them with cold water by about an inch. Add the tablespoon of salt to the water so the potatoes season from the inside as they cook. Bring the pot to a boil, then lower the heat and simmer 12 to 15 minutes until the potatoes feel very tender when you poke them with a fork.
Step 4: Build the garlic herb pan sauce
Lower the skillet heat to medium low and add the butter. Stir in the minced garlic and cook about 30 seconds to 1 minute until it smells fragrant and just turns lightly golden. Pour in the chicken broth and scrape up the browned bits from the bottom of the pan because those bits hold tons of flavor.
Step 5: Finish the sauce with cream and herbs
Whisk in the heavy cream and Dijon mustard until the sauce looks smooth and slightly thick. Stir in the fresh parsley and thyme, then squeeze in the lemon juice. Taste the sauce and adjust with more salt, pepper, or lemon if you want brighter flavor.
Step 6: Return the chicken to the pan
Place the browned chicken breasts back into the skillet and spoon some sauce over each piece. Let the chicken simmer in the sauce for 3 to 5 minutes so the flavors blend and the chicken warms through. Turn off the heat and keep the skillet covered while you finish the creamy mashed potatoes.
Step 7: Mash the potatoes
Drain the cooked potatoes in a colander and return them to the hot pot. Add the butter, half of the warm milk, sour cream, garlic powder, salt, and pepper. Mash until smooth and creamy, then add more warm milk as needed until the potatoes reach your favorite texture.
Step 8: Taste and adjust
Taste the mashed potatoes and season again with salt and pepper if they need more flavor. Taste the garlic herb chicken sauce and adjust the herbs or lemon juice to your liking. Spoon a generous scoop of creamy mashed potatoes onto each plate, top with sliced chicken, and drizzle with plenty of garlic herb sauce.
What to Serve with Garlic Herb Chicken
This garlic herb chicken with creamy mashed potatoes pairs nicely with simple green vegetables like steamed green beans, roasted broccoli, or sautéed spinach. A crisp side salad with romaine, cucumber, and a light vinaigrette cuts through the richness. You can also add buttered peas or roasted carrots for extra color and sweetness. Serve chilled sparkling water with lemon or a fruity iced tea to keep the meal refreshing.
Storage Options
- Store leftover garlic herb chicken and creamy mashed potatoes in separate airtight containers in the fridge for up to 3 to 4 days.
- Freeze the chicken and sauce together in a freezer-safe container for up to 2 months, and freeze mashed potatoes separately for best texture.
- Reheat the chicken and sauce gently on the stove over low heat with a splash of broth or water so the sauce loosens and the chicken stays tender.
- Warm the mashed potatoes in a pot over low heat or in the microwave, and stir in a little extra milk or butter to bring back their creamy texture.

Ingredients
Instructions
- Place the potato chunks in a large pot and cover with cold water by about 1 inch. Add 1 1/2 teaspoons salt.
- Bring to a boil over medium-high heat, then reduce to a gentle boil and cook until the potatoes are very tender, 15–20 minutes.
- Drain the potatoes well and return them to the warm pot. Let sit for 1–2 minutes to allow excess moisture to evaporate.
- Add the butter, warmed milk or half-and-half, sour cream (if using), and black pepper. Mash until smooth and creamy, adjusting salt and milk to taste.
- While the potatoes cook, pat the chicken breasts dry with paper towels. Season both sides with salt, black pepper, and paprika.
- Heat the olive oil in a large skillet over medium-high heat. Add the chicken breasts and sear until golden brown on both sides and cooked through, about 5–7 minutes per side depending on thickness. Transfer chicken to a plate and tent with foil.
- Reduce heat to medium. In the same skillet, add the butter. Once melted, stir in the minced garlic and cook for 30–60 seconds until fragrant, stirring constantly.
- Add the Italian seasoning and chicken broth, scraping up any browned bits from the bottom of the pan. Simmer for 2–3 minutes to slightly reduce. Stir in lemon juice if using and half of the chopped parsley.
- Return the chicken and any accumulated juices to the skillet, spooning the garlic herb butter sauce over the chicken. Simmer 1–2 minutes more to warm through.
- Spoon a generous portion of creamy mashed potatoes onto each plate.
- Top with a chicken breast and drizzle with extra garlic herb sauce from the skillet.
- Garnish with remaining chopped parsley and serve immediately.
