Recipe Overview

- Cook Time: 25 minutes
- Total Time: 40 minutes
- Yield: 6 servings
Ingredients
The Seasoning Blend
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon sweet paprika
- Salt and freshly ground black pepper (to taste)
The Main Components
- 2 pounds boneless, skinless chicken breasts (pounded to even thickness)
- 2 tablespoons unsalted butter (divided)
- 1 tablespoon extra-virgin olive oil
- 1 large yellow onion, thinly sliced into half-moons
- 2 cloves garlic, finely minced
- 1 chicken bouillon cube (or 1 teaspoon chicken base)
- 1/2 cup boiling water
- 1/2 cup dry white wine (such as Sauvignon Blanc or Pinot Grigio)
- 1 teaspoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1 cup full-fat sour cream (at room temperature)
- Fresh chopped parsley (for garnish)
Step-by-Step Instructions
1. Season the Chicken
In a small mixing bowl, whisk together the garlic powder, onion powder, sweet paprika, salt, and black pepper.
Pat the chicken breasts thoroughly dry with paper towels to ensure a good sear. Rub the spice blend evenly across both sides of every chicken breast. Set aside.
2. Sauté the Onions
Place a large, deep skillet or nonstick pan over medium heat. Add 1 tablespoon of butter and the olive oil. Once the butter has melted and stopped sizzling, add the sliced onions.
Cook them gently, stirring occasionally, until they soften and turn translucent (about 5 minutes). Transfer the cooked onions to a clean plate and set them aside, keeping the skillet on the heat.
3. Sear the Chicken
Add the remaining 1 tablespoon of butter to the same skillet and turn the heat up to medium-high. Once hot and bubbling, lay the seasoned chicken breasts in the pan.
Sear for roughly 3 minutes without moving them until a light golden crust forms. Flip the chicken over.
4. Build the Flavor Base
Scatter the reserved onions back into the skillet, nestling them around and on top of the chicken. Sprinkle the minced garlic directly into the pan. Let everything cook together for about 30 seconds until the garlic becomes deeply aromatic.
5. Simmer and Braise
In a separate cup, dissolve the chicken bouillon cube into the boiling water. Pour this chicken broth into the skillet along with the dry white wine, Worcestershire sauce, and Dijon mustard.
Bring the liquid to a robust boil, then cover the pan with a lid and lower the heat to medium-low. Allow it to simmer undisturbed for 10 to 15 minutes, or until the chicken is cooked through and registers an internal temperature of 165°F (74°C).
6. Enrich with Sour Cream
Remove the skillet completely from the heat source. Gently stir the full-fat sour cream straight into the pan juices, blending it continuously until a smooth, creamy, cohesive sauce coats the onions and chicken.
7. Garnish and Serve
Sprinkle fresh chopped parsley over the top for a bright, herbal contrast. Serve hot, spooning the extra sour cream and onion sauce generously over each portion.
Chef’s Cooking Tips
Prevent Curdling
To keep your sour cream from separating or curdling when added to a hot pan, take the skillet completely off the heat before stirring it in. Using full-fat sour cream also helps maintain a stable, velvety texture.
Wine Substitute
If you prefer not to cook with alcohol, you can replace the dry white wine with an equal amount of low-sodium chicken broth mixed with an extra squeeze of fresh lemon juice for acidity.
Even Cooking
For the best texture, ensure your chicken breasts are pounded to a uniform thickness so they finish cooking at the exact same rate.
