Ingredients:
- 2 lbs boneless, skinless chicken breast, cut into 1-inch cubes
- 1 lb cremini mushrooms, sliced
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 2 tbsp olive oil
- 2 tbsp unsalted butter
- 1/4 cup all-purpose flour
- 2 cups chicken broth, low sodium
- 1 tbsp Worcestershire sauce
- 1 tbsp Dijon mustard
- 3/4 cup full-fat sour cream, room temperature
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 tsp smoked paprika
- 2 tbsp fresh parsley, chopped
- 1 tbsp lemon juice
Instructions:
- Heat olive oil in a large heavy-bottomed skillet over medium-high heat. Add chicken cubes in a single layer and sear until mahogany-colored and golden on all sides (about 3-5 minutes). Remove chicken and set aside on a plate.
- In the same pan, melt the butter. Add the sliced mushrooms and sauté until they release their moisture and turn a deep golden brown.
- Stir in the diced onion and cook until translucent, then add the minced garlic and smoked paprika. Stir for 60 seconds until fragrant.
- Sprinkle the flour over the vegetables and whisk for 1-2 minutes to cook out the raw flour taste.
- Gradually pour in the chicken broth while whisking constantly to scrape up the brown bits (fond) from the bottom of the pan.
- Stir in the Worcestershire sauce and Dijon mustard. Season with salt and black pepper.
- Return the seared chicken and any accumulated juices to the pan. Simmer for a few minutes until the chicken is cooked through and the sauce has thickened.
- Remove the pan from the heat. Stir in the room-temperature sour cream and lemon juice until the sauce is velvety and smooth. This prevents the sauce from breaking.
- Stir in the fresh parsley and serve immediately over noodles or rice.
