Instructions
1. Prepare the Slow Cooker
Lightly grease the inside of your slow cooker to help prevent sticking and make cleanup easier.
2. Add the Chicken
Arrange the chicken breasts or thighs in a single, even layer inside the slow cooker.
3. Make the Sauce
In a medium bowl, whisk together the cream of chicken soup, chicken broth, and dry onion soup mix until smooth and well combined.
4. Pour Over the Chicken
Evenly pour the creamy onion mixture over the chicken, making sure each piece is well coated.
5. Slow Cook
Cover with the lid and cook:
- LOW: 5–6 hours
- HIGH: 2½–3 hours
The chicken is ready when it is tender and reaches an internal temperature of 165°F (74°C).
6. Add the Cheese
During the final 15–20 minutes of cooking, sprinkle the shredded cheddar cheese evenly over the chicken.
Replace the lid and continue cooking until the cheese is fully melted and creamy.
