Ingredients
Main Ingredients
| Ingredient | Amount | Notes |
| Boneless, skinless chicken breasts | 1 lb (450 g) | Cut into 1-inch cubes |
| Cooked ham | 1 lb (450 g) | Cut into 1-inch cubes |
| Russet or Yukon Gold potatoes | 4–5 medium | Peeled and diced |
| Frozen mixed vegetables | 1½ cups | Peas, carrots, and corn |
| Sharp cheddar cheese | 1½ cups | Shredded |
Creamy Sauce
| Ingredient | Amount |
| Condensed cream of chicken soup | 1 can (10.5 oz / 298 g) |
| Chicken broth or whole milk | ½ cup (120 ml) |
| Garlic powder | 1 teaspoon |
| Onion powder | 1 teaspoon |
| Black pepper | ½ teaspoon |
| Salt | ¼ teaspoon, or to taste |
Step-by-Step Instructions
1. Prepare the Slow Cooker
Lightly coat the inside of a 6-quart slow cooker with nonstick cooking spray.
This helps prevent the creamy sauce and cheese from sticking to the sides.
2. Add the Main Ingredients
Place the diced potatoes, chicken, ham, and frozen mixed vegetables into the slow cooker.
Spread everything into an even layer.
There is no need to thaw the frozen vegetables first.
3. Prepare the Creamy Sauce
In a medium bowl, whisk together the condensed cream of chicken soup, chicken broth or whole milk, garlic powder, onion powder, black pepper, and salt.
Whisk until the mixture is smooth and evenly combined.
Because ham and condensed soup can already contain considerable sodium, start with a small amount of salt and adjust after cooking if necessary.
4. Combine Everything
Pour the creamy soup mixture over the chicken, ham, potatoes, and vegetables.
Stir gently until the ingredients are evenly coated with the sauce.
5. Slow Cook
Cover the slow cooker with its lid.
Cook on:
- LOW: 4–6 hours
- HIGH: 3–4 hours
The casserole is ready when the potatoes are fork-tender and the chicken has reached a safe internal temperature of 165°F (74°C).
Avoid prolonged cooking once the chicken is done because diced chicken breast can become dry.
6. Add the Cheese
About 15–20 minutes before serving, remove the lid and sprinkle the shredded cheddar evenly over the casserole.
Replace the lid and continue cooking until the cheese has completely melted.
7. Rest and Serve
Turn the slow cooker to WARM and allow the casserole to rest for approximately 5 minutes.
Spoon the creamy chicken, ham, potatoes, vegetables, and melted cheese into bowls and serve hot.
Best Tips
Cut the potatoes evenly. Similar-sized pieces cook at approximately the same rate and help prevent some pieces from becoming overcooked while others remain firm.
Use Yukon Gold potatoes for extra creaminess. Russet potatoes work beautifully too, but they tend to become softer and more crumbly.
Don’t oversalt the casserole. Ham and condensed soup can both be salty, so taste and adjust carefully.
Shred your own cheddar when possible. Freshly shredded cheese generally melts more smoothly than many pre-shredded varieties.
Keep the lid closed. Repeatedly opening the slow cooker releases heat and can significantly extend the cooking time.
Best Ingredient Options
Chicken
Boneless, skinless chicken thighs can replace chicken breasts. They contain more fat and tend to remain particularly tender during slow cooking.
Ham
Leftover cooked ham is excellent for this recipe. Diced smoked ham can also add extra depth of flavor.
Potatoes
Yukon Gold potatoes provide a naturally buttery texture, while russet potatoes create a softer, starchier casserole.
Cheese
Sharp cheddar is ideal, but you can also use Monterey Jack, Colby, mild cheddar, or a cheddar-Monterey Jack blend.
Vegetables
Use frozen peas, carrots, and corn for convenience, or substitute with a frozen broccoli and cauliflower blend.
Recipe Variations
Bacon Cheddar Version
Add ½ cup of cooked, crumbled bacon just before serving for an extra smoky and savory flavor.
Ranch Chicken Casserole
Add 1 tablespoon of dry ranch seasoning to the creamy sauce for a ranch-inspired variation.
Broccoli Cheddar Version
Replace the mixed vegetables with frozen broccoli florets and use a cheddar and Monterey Jack cheese blend.
Mushroom Chicken Version
Use cream of mushroom soup instead of cream of chicken soup and add sliced mushrooms for a richer earthy flavor.
Spicy Version
Add ½ teaspoon of smoked paprika and a pinch of crushed red pepper flakes to the sauce.
What to Serve With
Because this casserole already contains chicken, ham, potatoes, vegetables, and cheese, it can easily serve as a complete family dinner.
For a lighter meal, serve it with a crisp green salad dressed with lemon vinaigrette.
Steamed green beans, roasted broccoli, or a simple cucumber salad also pair beautifully with the creamy casserole.
For a hearty comfort-food dinner, serve it with warm dinner rolls or crusty bread to soak up the creamy sauce.
Make-Ahead Instructions
You can dice the chicken, ham, and potatoes several hours ahead and refrigerate them separately in airtight containers.
The creamy sauce can also be mixed in advance and refrigerated until you’re ready to cook.
For food safety, keep raw chicken refrigerated at 40°F (4°C) or below until cooking.
For the best texture, assemble and begin cooking the casserole according to the recipe rather than allowing raw ingredients to sit at room temperature.
Storage
Allow leftovers to cool promptly, then transfer them to an airtight container.
Refrigerate within 2 hours of cooking and store at 40°F (4°C) or below.
The casserole is best consumed within 3–4 days.
Reheating
For individual portions, microwave on medium power in short intervals, stirring between intervals, until heated through.
You can also reheat larger portions in a covered oven-safe dish at 350°F (175°C) until hot throughout.
Add a small splash of chicken broth or milk if the sauce has thickened significantly.
Freezing
This casserole can be frozen, although the texture of the potatoes and creamy sauce may change slightly after thawing.
For best results, cool completely before transferring to a freezer-safe airtight container.
Freeze for up to approximately 2–3 months for best quality.
Thaw overnight in the refrigerator before reheating thoroughly.
Common Mistakes to Avoid
Using very large potato pieces: Large chunks may remain firm when the chicken is already cooked.
Adding too much liquid: The ingredients release moisture during slow cooking, so avoid adding extra broth beyond the recipe amount.
Adding cheese too early: Cheese added at the beginning can become greasy or develop an undesirable texture. Add it near the end.
Overcooking the chicken: Chicken breast becomes dry when cooked for substantially longer than necessary.
Opening the lid repeatedly: Every unnecessary lid opening releases accumulated heat and moisture.

Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs are an excellent substitute and can provide a more tender and flavorful result.
Do I need to cook the chicken first?
No. The chicken can be added directly to the slow cooker as diced raw chicken. Make sure it reaches 165°F (74°C) internally before serving.
Can I use leftover ham?
Absolutely. This is an excellent way to use leftover cooked holiday ham.
Can I use fresh vegetables instead of frozen?
Yes. Fresh peas, carrots, corn, broccoli, or other vegetables can be substituted. Cut firmer vegetables into relatively small pieces so they cook evenly.
Can I make this without canned cream soup?
Yes. Replace the condensed soup with a homemade cream sauce made from butter, flour, milk or broth, and seasonings.
Can I use a different cheese?
Definitely. Cheddar, Monterey Jack, Colby, Pepper Jack, or a combination of cheeses all work well.
Why is my casserole watery?
The chicken, vegetables, and potatoes naturally release moisture during cooking. If the finished casserole is thinner than desired, leave the lid slightly ajar for a short period on HIGH or allow it to rest uncovered for several minutes before serving.
