Getting the ingredients together for this Slow Cooker Green Bean Casserole with Chicken Recipe couldn’t be simpler, yet each component plays a crucial part in building flavor, texture, and that classic creamy casserole charm. Here’s what you’ll need to make this cozy dish shine:

2 chicken breasts: The star protein that keeps the casserole hearty and satisfying.
3 cups green beans (fresh or frozen): Brings bright color and a lovely crunch that balances the creaminess.
1 onion, diced: Adds a subtle sweetness and depth to the overall flavor profile.
1 can cream of mushroom soup (or homemade): Provides that classic creamy base that ties everything together.
1/2 cup milk: Lightens the consistency of the soup for a smooth texture.
1 tsp garlic powder: A gentle punch of savory flavor without overpowering the dish.
1 tsp onion powder: Enhances the onion’s natural sweetness even further.

1 cup crispy fried onions (added at end): The golden, crunchy topper that provides irresistible texture contrast.

How to Make Slow Cooker Green Bean Casserole with Chicken Recipe

Step 1: Prepare the Slow Cooker Base

Start by placing your chicken breasts right into the slow cooker. This creates a savory foundation for your casserole. Then add the green beans and diced onions evenly over the top, layering the fresh ingredients so they cook evenly and absorb all the delicious flavors.

Step 2: Mix the Creamy Sauce

In a separate bowl, whisk together the cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper. This creamy mixture is what will give your casserole that iconic rich texture and mouthwatering flavor. Once combined, pour it evenly over the chicken and vegetables, making sure every bite gets coated.

Step 3: Start Cooking

Set your slow cooker on low for 6 hours or high for 3 to 4 hours. This slow, gentle cooking process lets the chicken become tender and juicy while the green beans soften just right without losing their bite. The flavors have plenty of time to meld together, resulting in a beautifully unified dish.

Step 4: Shred and Stir

Once cooking is complete, use two forks to shred the chicken directly in the slow cooker. Stir everything thoroughly so the chicken mixes evenly with the green beans and creamy sauce, giving you that classic casserole consistency everyone loves.

Step 5: Add Crispy Onions and Serve

Just before serving, sprinkle the crispy fried onions on top. This crunch is an absolute game changer, adding texture and that unmistakable golden finish that feels like the ultimate comfort food touch.

Make Ahead and Storage

Storing Leftovers

This casserole keeps wonderfully in the fridge for up to 3 days. Store it in an airtight container to preserve freshness and prevent moisture from making the fried onions soggy. When you’re ready to eat, it reheats beautifully without losing its charm.

Freezing

You can freeze this dish before adding the fried onions. Portion it into airtight containers or freezer bags, then store for up to 2 months. When thawed, just reheat and add the crispy onions for that perfect finish.

Reheating

Reheat gently in the microwave or oven until warm throughout. Add the crispy fried onions at the very end to keep their crunch intact. This way, you get that fresh-from-the-slow-cooker feel every time.

FAQs

Can I use frozen green beans for this recipe?

Absolutely! Frozen green beans work just as well and save you prep time. Just make sure not to thaw them beforehand to avoid a mushy texture in the casserole.

Is it possible to make this dish dairy-free?

Yes, swap the canned cream of mushroom soup with a homemade or store-bought dairy-free version and use your favorite non-dairy milk. This keeps the dish creamy without any dairy.

Can I add mushrooms to the casserole?

Definitely! Adding fresh or sautéed mushrooms will deepen the earthiness and make the casserole even heartier. Just toss them in along with the green beans and onions.

How do I make sure the chicken is tender?

Cooking on low for the full 6 hours is key to getting tender, juicy chicken that shreds easily. Avoid opening the slow cooker too often during cooking to maintain temperature consistency.
