Honestly, the sweet caramelized onions and creamy, savory sauce make this recipe taste like it took much more effort than it actually did. It’s simple, comforting, and always a family favorite.
Ingredients
- 2 lbs boneless, skinless chicken breasts
- 2 large yellow onions, thinly sliced
- 2 tbsp butter
- 2 tbsp olive oil
- 3 cloves garlic, minced
- 1 packet (1 oz) French onion soup mix
- 1 cup low-sodium chicken broth
- 1 tbsp Worcestershire sauce
- 1 tsp dried thyme
- ½ tsp black pepper
- 4 oz cream cheese, softened
- ½ cup sour cream
- 1 tbsp cornstarch (optional)
- 2 tbsp water (optional, for thickening)
- Fresh parsley, chopped (for garnish)
Step-by-Step Method
Step 1: Caramelize the Onions
Heat butter and olive oil in a skillet over medium heat. Add the sliced onions and cook for 20–25 minutes, stirring occasionally, until they are golden brown and caramelized. Add the garlic and cook for another minute.
Step 2: Assemble the Slow Cooker
Place the chicken breasts in the slow cooker. Sprinkle the French onion soup mix over the chicken. Top with the caramelized onions.
Step 3: Add the Liquid
Pour in the chicken broth and Worcestershire sauce. Sprinkle with dried thyme and black pepper.
Step 4: Slow Cook
Cover and cook on Low for 6–7 hours or High for 3–4 hours, until the chicken is tender and easy to shred.
Step 5: Make It Creamy
Shred the chicken directly in the slow cooker using two forks. Stir in the cream cheese and sour cream until smooth and creamy. If you’d like a thicker sauce, stir in the cornstarch mixed with water and cook for another 15–20 minutes.
Step 6: Serve
Garnish with fresh parsley and serve warm over mashed potatoes, rice, buttered noodles, or toasted bread.
