- 2 tablespoons butter
- ½ cup heavy whipping cream
- 1 teaspoon salt
For the Chicken:
- 4 chicken breasts
- 2 tablespoons butter
- 1 tablespoon olive oil
- ½ teaspoon garlic powder
- Salt and pepper, to taste
For the Dijon Cream Sauce:
- 2 tablespoons butter
- 2 cloves garlic, minced
- 1 tablespoon all-purpose flour
- ½ cup chicken broth
- ½ cup dry white wine (or more chicken broth)
- 2-3 tablespoons dijon mustard (adjust to taste)
- ½ teaspoon salt

How to Make It
Step 1: Cook the Mashed Potatoes
Place peeled and quartered potatoes in a large pot. Cover with water and bring to a boil. Cook until fork-tender, about 15-20 minutes. Drain and return to pot. Add butter, heavy cream, and salt, then mash until smooth and creamy. Keep warm.
Step 2: Prepare the Chicken
Season chicken breasts with garlic powder, salt, and pepper. Heat butter and olive oil in a large oven-safe skillet over medium-high heat. Sear the chicken for about 5 minutes per side, until golden brown. Remove chicken and set aside.
Step 3: Make the Dijon Cream Sauce
Reduce heat to medium. In the same skillet, melt butter and sauté garlic until fragrant. Whisk in flour and cook for 1 minute. Gradually add chicken broth and white wine while whisking. Stir in dijon mustard, salt, and pepper. Pour in heavy cream and simmer 1-2 minutes until slightly thickened.
Step 4: Combine and Bake
Return the chicken to the skillet, spoon sauce over top, and transfer the skillet to a preheated oven at 375°F (190°C). Bake for 15-18 minutes, or until chicken is cooked through.
Step 5: Serve
Plate the chicken and spoon extra dijon cream sauce over fluffy mashed potatoes. Garnish with chopped parsley if desired. Enjoy!
Tips & Substitutions
- Mustard: Dijon mustard adds the perfect creamy tang, but if you prefer a milder taste, start with 1 tablespoon and adjust. Avoid substituting yellow mustard as the flavor and color differ significantly.
- Wine: Use a dry white wine, such as Sauvignon Blanc or Pinot Grigio. If you prefer to skip alcohol, replace the wine with extra chicken broth.
- Oven-Safe Skillet: If your skillet isn’t oven-safe, transfer chicken and sauce to a baking dish before baking.
- Mashed Potatoes: For extra creamy potatoes, use an electric mixer, or mash by hand if you prefer a chunkier texture.
