Ingredients

1 1/2 pounds chicken breast
Salt and pepper
1 tbsp olive oil
2 tbsp butter
2 small-medium sweet onions thinly sliced
2 tsp brown sugar
3 garlic cloves minced
1 1/2 cups chicken broth
1 tbsp spicy brown mustard
1/2 tbsp Worcestershire sauce
3/4 cup sour cream

Instructions

Cut the chicken breasts in half lengthwise and season each side with salt and pepper.
Heat a deep skillet over medium heat and add the olive oil. Once hot, add the chicken and brown each side for about 3 minutes, then remove from the pan.
Add the butter to the pan. Once melted, add the onion, brown sugar, and a pinch of salt. Cook the onions on medium-low for about 20 minutes or until mostly caramelized and soft.
Add the minced garlic and saute for another 1-2 minutes.
Add the broth, mustard, and Worcestershire. Stir to combine and bring to a simmer, then whisk in the sour cream. Taste the sauce and add more salt or pepper if desired.
Add the chicken back to the pan and cook for another 3 minutes per side to warm back up and finish cooking through.
Serve with desired sides and freshly cracked black pepper and enjoy!

Notes

Take your time with the onions: The key to that deep, rich flavor is patience. Let the onions cook slowly over medium-low heat until golden and jammy — it’s worth every minute!
Use full-fat sour cream: It creates a richer, silkier sauce that won’t curdle when added to the pan.
Avoid boiling the sauce: Once the sour cream is in, keep the heat low and stir gently to maintain that creamy texture.
Adjust to your taste: Add extra mustard or Worcestershire if you like a bolder, tangier flavor.
Perfect for meal prep: The sauce keeps beautifully — just reheat over low heat with a splash of broth or cream.
Serving idea: Try it over mashed potatoes, rice, or egg noodles to soak up all that delicious sauce.
Make it your own: Add mushrooms, spinach, or a sprinkle of shredded cheese for extra flavor.
