There are some dinners that just feel like home, and honestly, this Slow Cooker Cheesy Chicken, Beef & Potato Casserole is one of them.
I usually make this kind of meal when I want something filling and comforting without spending hours standing in the kitchen. Everything cooks together slowly, allowing the potatoes to become tender, the chicken to soak up all those delicious flavors, and the beef and beans to create a rich, savory sauce.
The melted cheese on top is my favorite part. It gets beautifully gooey and golden while the tomato-based sauce bubbles underneath.
What I really love about this recipe is how hearty it is. You get tender chicken, seasoned ground beef, soft potatoes, kidney beans and tomatoes all in one dish. Serve it with some crusty bread or a simple salad, and dinner is done!
Ingredients
For the Casserole
- 4 boneless or bone-in chicken thighs
- 1 pound (450 g) ground beef
- 4–5 medium potatoes, cut into large chunks
- 1 can (15 oz/425 g) kidney beans, drained and rinsed
- 1 can (14–15 oz/400 g) diced tomatoes
- 1 cup tomato sauce or crushed tomatoes
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 1½ cups shredded mozzarella or cheddar cheese
- 1 tablespoon olive oil
Seasonings
- 1 teaspoon paprika
- 1 teaspoon Italian seasoning
- 1 teaspoon chili powder
- ½ teaspoon dried oregano
- ½ teaspoon black pepper
- 1 teaspoon salt, or to taste
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika, optional
- ½ cup chicken or beef broth, if needed
Step-by-Step Method
1. Prepare the Ingredients
Start by washing and cutting the potatoes into fairly large chunks. I recommend keeping them similar in size so they cook evenly.
Drain and rinse the kidney beans and set them aside.
Chop the onion and mince the garlic.
2. Brown the Ground Beef
Heat a large skillet over medium-high heat and add the olive oil.
Add the ground beef and cook until browned, breaking it apart with a wooden spoon as it cooks.
Add the chopped onion and garlic and cook for another 2–3 minutes until the onion begins to soften.
Season with paprika, chili powder, oregano, Italian seasoning, black pepper and a little salt.
Honestly, browning the beef first makes a noticeable difference. It gives the casserole a deeper, richer flavor.
3. Layer the Slow Cooker
Place the potato chunks into the bottom of your slow cooker.
Add the kidney beans and diced tomatoes.
Spoon the seasoned ground beef mixture over the top.
Nestle the chicken thighs into the mixture.
Pour the tomato sauce over everything. If the mixture looks particularly thick, add about ½ cup of broth.
4. Slow Cook Until Tender
Cover the slow cooker with the lid.
Cook on LOW for about 6–7 hours or on HIGH for about 3–4 hours, depending on your slow cooker and the size of the chicken pieces and potatoes.
The potatoes should be fork-tender and the chicken should be fully cooked.
5. Add the Cheese
Once everything is cooked and tender, sprinkle the shredded cheese evenly over the top.
Cover again and cook for another 10–15 minutes, or until the cheese is completely melted.
For a slightly golden top, transfer the casserole to an oven-safe dish and place it briefly under the broiler, watching carefully.
6. Rest and Serve
Turn off the slow cooker and let the casserole rest for about 5 minutes.
Spoon generous portions onto plates, making sure everyone gets plenty of chicken, potatoes, beef, beans and that delicious cheesy tomato sauce.
Cooking Tips
Cut the potatoes evenly
Try to cut the potatoes into similar-sized chunks. Very large pieces may take longer to become tender.
Don’t skip browning the beef
You can technically add raw ground beef to some slow cooker recipes, but I prefer browning it first. It adds much more flavor and improves the texture.
Use your favorite cheese
Cheddar gives you a stronger flavor, while mozzarella creates that lovely stretchy, gooey texture. A combination of both works beautifully.
Don’t add too much liquid
The tomatoes and meat will release liquid as they cook, so you don’t want the casserole swimming in broth. Add only a little extra broth if needed.
Keep the chicken pieces together
If using bone-in chicken thighs, they tend to stay especially juicy during slow cooking.
Check the chicken
Chicken should reach a safe internal temperature of 165°F (74°C) in the thickest part.
Serving Suggestions
This casserole is filling enough to serve on its own, but I usually like adding something fresh on the side.
Try serving it with:
- Crusty garlic bread
- Fresh green salad
- Steamed vegetables
- Coleslaw
- Corn on the cob
- Dinner rolls
- Simple cucumber and tomato salad
A little chopped fresh parsley or green onion sprinkled over the top also adds a nice fresh finish.
