Slow Cooker Green Bean And Chicken Casserole
There are some dinners that feel like a warm hug the second you walk through the door, and this is one of those meals. This is the kind of recipe I make on days when the schedule is packed, everyone is tired, and I just want something solid and comforting waiting for us at dinner time. The kind of dinner where you open the slow cooker, steam rolls up, and suddenly the whole house smells like home.

I first started making this Slow Cooker Green Bean And Chicken Casserole during one of those busy seasons of life where afternoons blurred into evenings. Kids had activities, work ran late, and the idea of turning on the oven felt like too much. I wanted something hearty, something familiar, and something that did not require babysitting. That is when the slow cooker stepped in like an old reliable friend.
This recipe takes everything you love about classic green bean casserole and turns it into a full meal. You get tender chicken breasts that cook until they are soft enough to cut with a spoon, a creamy savory sauce that wraps around every bite, and those crispy fried onions on top that make everyone smile. It tastes like the holidays but works perfectly for a random Tuesday night.
What I love most is how forgiving this recipe is. You toss things in, layer it up, walk away, and let time do the work. By the time dinner rolls around, you have a comforting casserole style dinner that feels like you tried a whole lot harder than you actually did. Those are my favorite kinds of recipes, and once you make this one, I have a feeling it will earn a permanent spot in your slow cooker rotation.

How to Make Slow Cooker Green Bean And Chicken Casserole
Step 1: Prepare the Slow Cooker
Spray an eight quart slow cooker generously with non stick cooking spray. This helps prevent sticking and makes cleanup much easier later.
Step 2: Season the Chicken
Lay the chicken breasts evenly across the bottom of the slow cooker. Sprinkle the garlic salt, onion powder, and paprika evenly over the chicken so every piece is well seasoned.

Step 3: Mix the Stuffing Layer
In a large bowl, combine the chicken broth, chicken stuffing mix, and chicken gravy. Stir until everything is evenly moistened and combined. Spread this mixture evenly over the seasoned chicken.


Step 4: Add the Creamy Layer
In a medium bowl, stir together the sour cream and cream of mushroom soup until smooth. Spread this mixture gently over the stuffing layer, covering it completely.


Step 5: Slow Cook
Cover the slow cooker and cook on low for five to six hours. The chicken will become tender and the casserole will thicken beautifully as it cooks.
Step 6: Add the Green Beans
During the last hour of cooking, add the frozen green beans and gently spread them throughout the casserole. Replace the lid and continue cooking until the beans are heated through.

Step 7: Finish and Serve
Once fully cooked, scoop the casserole onto plates and sprinkle crispy fried onions on top if using. Serve warm and enjoy every comforting bite.

Substitutions
Turkey gravy: You can swap chicken gravy for turkey gravy for a holiday inspired twist.
Turkey stuffing mix: Turkey stuffing works just as well and adds seasonal flavor.
Canned green beans: Drain very well before adding if using canned instead of frozen.
Greek yogurt: Plain Greek yogurt can replace sour cream for a lighter option.
Variations
- Cheesy version: Add shredded cheddar or mozzarella during the last thirty minutes for extra richness.
- Vegetable boost: Stir in sliced mushrooms or carrots for added texture and nutrition.
- Herb flavor: Add dried thyme or parsley to enhance the savory profile.
- Crunch topping: Mix fried onions with crushed crackers for an extra crispy finish.
Tips and Tricks
- Even layering: Keep layers even so everything cooks at the same pace.
- Low and slow: Cooking on low gives the best texture and flavor.
- Do not over stir: Let the layers stay mostly intact for the best casserole consistency.
- Rest before serving: Let it sit for ten minutes to thicken before scooping.

FAQs
Can I cook this on high?
