Ingredients

For the Chicken

• 4 boneless, skinless chicken breasts or thighs
• 1 medium onion, sliced
• 2 cloves garlic, minced
• 2 cups chicken broth
• 1 can (10.5 ounces) cream of chicken soup
• 1 teaspoon dried thyme
• 1 teaspoon garlic powder
• ½ teaspoon black pepper
• Salt, to taste
• 2 tablespoons butter

For the Mashed Potatoes

• 2 pounds potatoes, peeled and cubed
• 4 tablespoons butter
• ½ cup warm milk
• Salt and black pepper, to taste

How to Make Slow Cooker Chicken

1. Prepare the Chicken

Season the chicken breasts or thighs with garlic powder, thyme, black pepper, and a little salt.

Place the sliced onion and minced garlic in the bottom of the slow cooker.

Arrange the seasoned chicken over the onions.

2. Make the Gravy

In a bowl, whisk together the chicken broth and cream of chicken soup until smooth.

Pour the mixture around the chicken.

Add the butter on top.

3. Slow Cook

Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the chicken reaches an internal temperature of 165°F (74°C) and is tender.

Avoid cooking boneless chicken longer than necessary because it can become dry.

4. Prepare the Mashed Potatoes

While the chicken finishes cooking, place the peeled potatoes in a large pot of salted water.

Bring to a boil and cook until fork-tender, about 15–20 minutes.

Drain thoroughly.

Add the butter and warm milk, then mash until smooth and creamy. Season with salt and black pepper.

5. Finish the Chicken

Remove the chicken from the slow cooker and let it rest for a few minutes.

If desired, shred or slice the chicken.

Stir the cooking liquid well to create a smooth gravy.

For thicker gravy, transfer the liquid to a saucepan and thicken with a small cornstarch slurry.

6. Serve

Spoon a generous portion of mashed potatoes onto each plate.

Place the tender chicken on top and ladle plenty of savory gravy over everything.

Garnish with a little fresh parsley if desired.

Tips for the Best Slow Cooker Chicken

Chicken thighs are especially good for slow cooking because they tend to stay juicy and flavorful.

Don’t add excessive salt at the beginning because canned soup and chicken broth can already contain significant sodium.

For richer mashed potatoes, use warm whole milk and plenty of butter.

If the gravy is too thin, thicken it separately rather than adding a large amount of flour directly to the slow cooker.

Easy Variations

Add carrots, peas, mushrooms, or celery to the slow cooker for extra vegetables.

For a garlic-herb version, add fresh rosemary and thyme.

You can also replace the cream of chicken soup with a homemade cream sauce if preferred.

What to Serve With This Chicken Dinner

Because the chicken is served over mashed potatoes and gravy, it already makes a hearty meal. Add green beans, roasted carrots, steamed broccoli, corn, or a simple side salad for extra vegetables.

Warm dinner rolls are also perfect for soaking up the leftover gravy.

How to Store Leftovers

Store the chicken, gravy, and mashed potatoes in separate airtight containers in the refrigerator for up to 3–4 days.

Reheat the chicken and gravy gently until thoroughly heated.

Add a splash of milk to the mashed potatoes before reheating if they have become dry.

Frequently Asked Questions

Can I use chicken thighs?

Yes. Boneless, skinless chicken thighs are an excellent option and work particularly well in the slow cooker.

Can I add vegetables?

Absolutely. Carrots, peas, mushrooms, and green beans all work well.

Can I make the mashed potatoes ahead?

Yes. Prepare them ahead and refrigerate them. Reheat gently with a little warm milk and butter to restore their creamy texture.

This Slow Cooker Chicken Dinner Over Mashed Potatoes is simple, hearty, and wonderfully comforting. Tender chicken cooks slowly in a savory gravy before being served over creamy mashed potatoes.
