Chicken with Creamy Dijon Sauce and Mashed Potatoes

Ingredients Section

Getting the right ingredients is key to achieving that perfect balance of creamy and tangy in this restaurant-quality dish.

Mashed Potatoes

2 pounds russet potatoes: I prefer to use russet potatoes for their high starch content, which results in the fluffiest, whitest mashed potatoes that hold the sauce beautifully.
2 tablespoons butter: Used for mashing into the potatoes to create a rich, buttery flavor and to help them become silky smooth.
1/2 cup heavy whipping cream: Using heavy cream, rather than milk, is a must as it gives the mashed potatoes a much richer flavor and a velvety, luxurious mouthfeel.
1 teaspoon salt: Needed for seasoning the potatoes after they are drained; salt is essential to enhance the potato’s natural flavor.

Chicken

2 tablespoons butter: Used alongside the olive oil to sear the chicken, creating a deep, golden-brown crust that locks in the juices.
1 tablespoon olive oil: Mixing the oil with butter helps to raise the smoke point in the pan, preventing the butter from burning before the chicken can get a good sear.
4 chicken breasts: I recommend using medium-sized chicken breasts; if they are very large, consider slicing them horizontally into thinner cutlets for faster, more even cooking.
1/2 teaspoon garlic powder: Used for seasoning the chicken before searing, it provides a mellow, aromatic flavor base for the sauce.
salt, to taste: Used to liberally season both sides of the chicken before searing to ensure the meat is flavorful all the way through.
pepper, to taste: Freshly ground pepper is best for seasoning the chicken, adding a sharp, aromatic finish.

Dijon Cream Sauce

2 tablespoons butter: Added to the skillet after the chicken is removed; this is the base for sautéing the garlic and building the sauce.
2 garlic cloves, minced: Freshly minced garlic is crucial here; it provides a much brighter, more fragrant base for the sauce than dried garlic.
1 tablespoon all-purpose flour: This is the perfect amount to slightly thicken the sauce, creating a light roux that gives the sauce a desirable, drizzling consistency.
1/2 cup chicken broth: The main liquid base for the sauce; using Better Than Bouillon is a smart trick to avoid having an open carton of broth sitting in the fridge.
1/2 cup dry white wine: The acidity in the wine is key to deglazing the pan and adding a complex depth of flavor; make sure to use a dry wine, not a sweet one, or substitute with more chicken broth.
2-3 tablespoons dijon mustard: The star ingredient, which gives the sauce its signature tangy, creamy, and slightly spicy flavor; you can start with less and add more to taste.
1/2 teaspoon salt: Needed to season the sauce to perfection, adjusting for the saltiness of your broth and mustard.
1/4 teaspoon pepper: A little extra pepper is added to the sauce to give it a final aromatic kick before the cream is added.
1 cup heavy whipping cream: This makes the sauce incredibly rich, luscious, and thickens beautifully to a perfect, gravy-like consistency.
optional garnish: chopped parsley: A final addition that provides a pop of fresh, herbaceous flavor and a beautiful green color for presentation.

Note: several serving

Variations

This recipe is very flexible and can be adapted to fit different dietary needs or to enhance the flavor profile with just a few simple swaps.

Dairy-free: Swap the heavy cream for full-fat coconut milk and use a dairy-free butter alternative. The flavor will be a bit different but still creamy.
Sugar-free/low sugar: The recipe already avoids added sugar; just make sure your chicken broth has no added sugars.
Lighter version: Use half heavy cream and half low-fat milk (if dairy is okay) for the sauce, and skip the oil in searing—just butter.
Flavor add-ins: Try stirring in a bit of chopped fresh thyme or rosemary into the sauce for herbal notes. Or add a teaspoon of whole grain mustard with the Dijon for texture.
Gluten-free: Use a gluten-free flour blend or cornstarch (½ teaspoon) instead of the all-purpose flour to thicken the sauce.

Cooking Time

This dish is designed to come together efficiently using a one-pan method for the chicken and sauce.

Equipment you need

Having the right kitchen tools ready will make this cooking process smooth and ensure a great final result.

Oven-safe skillet: Essential for searing the chicken on the stovetop and then transferring the whole dish to the oven for the final cook in the sauce.
Pot: A large pot is needed for boiling the potatoes until they are tender enough to be mashed.
Whisk: Crucial for incorporating the flour into the butter and liquids to ensure the Dijon cream sauce is perfectly smooth and free of any lumps.
Potato masher or electric mixer: Used to achieve that silky, creamy texture in the mashed potatoes by thoroughly blending them with the butter, cream, and salt.

How to Make Chicken with Creamy Dijon Sauce and Mashed Potatoes?

This recipe cleverly uses a one-skillet method for the chicken and sauce, concentrating all the delicious flavors into one pan.

Prepare the mashed potatoes

Start by peeling and quartering the russet potatoes, then bring a pot of salted water to a boil and cook the potatoes until fork-tender. Once done, drain them, return them to the pot, add the butter, heavy cream, and salt. Use a potato masher (or an electric mixer for ultra smooth) to mash until creamy. Cover to keep warm while you work on the chicken and sauce.

Sear the chicken

Season the chicken breasts on both sides with salt, pepper, and garlic powder. Heat the butter and olive oil in your oven-safe skillet over medium-high heat. Once hot, add the chicken and sear for about 5 minutes on each side until golden. Remove the chicken from the skillet and set aside—this step locks in flavor and gives a nice crust.

Make the Dijon cream sauce & finish cooking

Reduce the heat to medium in the same skillet. Add the butter and minced garlic and cook until the garlic is fragrant. Whisk in the flour and cook about a minute. Gradually pour in the chicken broth and dry white wine (or extra broth), whisking constantly. Then whisk in the Dijon mustard, salt, pepper, and heavy cream. Let it simmer for 1-2 minutes until slightly thickened to a gravy consistency. Add the chicken back into the skillet with the sauce, then transfer the skillet to a preheated oven (375°F/190°C) and bake for about 15-18 minutes, or until the chicken is cooked through.

Serve

Remove the skillet from the oven, let everything rest for a moment, then serve the chicken breasts perched over a bed of mashed potatoes. Spoon extra sauce from the skillet over the top, garnish with chopped parsley if using, and enjoy right away.

🇫🇷 France: The Heart of Burgundy’s Culinary Elegance

In the enchanting region of Burgundy, France, food is more than nourishment. It’s an art form deeply tied to the land.

This area is world-famous for its Dijon mustard, fine wines, and rustic yet refined cuisine.

Surrounded by rolling vineyards and charming villages, Burgundy’s cooking captures the true essence of French countryside sophistication and slow, soulful dining.

Additional Tips for Making this Recipe Better

Through my own cooking experience, I’ve picked up a few easy tips that truly elevate the flavor and texture of this dish.

I found that if my chicken breasts are quite thick, I like to butterfly them or slice them into thinner cutlets before searing. This not only speeds up the cooking time but also ensures they are perfectly tender and not dry when they finish baking in the sauce.
I always recommend using a mix of both garlic powder for the chicken seasoning and fresh minced garlic for the sauce. The powder adheres better to the meat, while the fresh garlic provides a much more aromatic and vibrant base for the Dijon cream sauce.
To prevent the mashed potatoes from cooling down too much, I like to wrap the pot I keep them in with a kitchen towel before putting the lid on. This insulation helps them stay piping hot while the chicken finishes its last 15 minutes in the oven.
If you find the sauce gets too thick while it simmers, I suggest having a small amount of extra chicken broth ready. You can whisk in a tablespoon at a time until the sauce reaches that perfect, glossy, drizzling consistency you’re aiming for.
