Ingredients

• 2 to 2½ pounds boneless skinless chicken breasts
• 1 packet (1.5 oz) dry onion soup mix
• 1 can (10.5 oz) cream of chicken soup or cream of mushroom soup

Directions

1. Prepare the Slow Cooker

Lightly spray the inside of your slow cooker or crockpot with non-stick cooking spray to make cleanup easier.

2. Add the Chicken

Place the chicken breasts in a single layer at the bottom of the slow cooker. Slight overlapping is fine, but keeping them mostly flat helps them cook evenly.

3. Mix the Sauce

In a small bowl, combine the dry onion soup mix and cream of chicken soup. Stir well until the mixture becomes thick and creamy.

4. Coat the Chicken

Spread the creamy onion mixture evenly over the chicken. Do not add water or broth, as the chicken will release juices during cooking to create a flavorful sauce.

5. Slow Cook

Cover with the lid and cook:

• LOW: 4 to 6 hours
• HIGH: 2½ to 3½ hours

Cook until the chicken is tender and reaches an internal temperature of 165°F (74°C).

6. Shred or Serve Whole

Once cooked, you can either leave the chicken breasts whole or gently shred them into chunks using two forks. Stir lightly so the chicken is well coated in the creamy onion sauce.

7. Serve

Serve the creamy onion chicken hot over:

• Mashed potatoes
• Steamed white or brown rice
• Buttered egg noodles

Add a side of green beans, roasted broccoli, or a fresh salad for a balanced meal.

Tips and Variations

Make it extra creamy:
Stir in 2–4 tablespoons of sour cream or Greek yogurt at the end of cooking for a richer sauce.

Add vegetables:
Mix in sliced mushrooms or frozen peas during the last 20 minutes of cooking.

Use chicken thighs:
Boneless skinless chicken thighs can be used for an even juicier and more tender slow cooker chicken dish.

Thicken the sauce:
If you prefer a thicker gravy, remove the lid during the last 20–30 minutes on HIGH to let the sauce reduce slightly.
