What Ingredients are in Creamy Cheesy Chicken Green Bean Casserole?
This casserole is all about comfort food simplicity with ingredients that create layers of flavor and texture. The combination of tender chicken, fresh green beans, and a creamy cheese sauce makes for a hearty meal that’s satisfying any night of the week. What I love most about this recipe is how accessible the ingredients are—most of these items might already be sitting in your refrigerator or pantry right now.
- 1 1/2 cups fresh cut French style green beans
- 1 tablespoon salted butter
- 2 celery ribs, raw
- 1 medium yellow onion
- 1/2 cup light mayonnaise
- 1/4 cup evaporated milk (2%)
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 8 ounces fancy shredded mild cheddar cheese
- 2 cups diced chicken breasts
When shopping for ingredients, consider the freshness of your green beans—they should be crisp and vibrant for the best texture. You can substitute regular mayonnaise if you don’t have light on hand, though it will make the dish a bit richer. And while the recipe calls for mild cheddar, don’t be afraid to experiment with medium or sharp cheddar if you prefer a more pronounced cheese flavor. The chicken should be pre-cooked, so this is a perfect opportunity to use up leftover rotisserie chicken or meal-prepped chicken breasts from earlier in the week.
How to Make this Creamy Cheesy Chicken Green Bean Casserole
Making this casserole is a breeze, even on those hectic weeknights when cooking feels like climbing Mount Everest. Start by grabbing a skillet and melting 1 tablespoon of salted butter over medium heat. Add your 2 raw celery ribs (chopped) and 1 medium yellow onion (diced) to the butter and sauté until they’re nicely browned and aromatic. There’s something so comforting about the smell of onions and celery cooking down in butter, isn’t there? It’s like a warm kitchen hug.
Once your veggies are golden, transfer them to a 2½-3 quart casserole dish along with 1½ cups of fresh cut French style green beans.
Now comes the creamy magic – in a separate bowl, combine ½ cup of light mayonnaise, ¼ cup of 2% evaporated milk, ½ teaspoon of black pepper, and ¼ teaspoon of garlic powder. Whisk these ingredients together until smooth, then pour this velvety mixture over your vegetables in the casserole dish. Give everything a good stir to guarantee those beans and veggies are coated in all that creamy goodness.
Next, fold in 8 ounces of fancy shredded mild cheddar cheese and 2 cups of diced chicken breasts, making sure everything is evenly distributed. The cheese will melt into little pockets of joy throughout the casserole.
Pop your creation into a preheated 350°F oven and bake uncovered for 30-40 minutes, or until the top is bubbly and beautifully browned. If you’re in a time crunch, you can also microwave the casserole on MEDIUM for about 20-30 minutes, stopping occasionally to stir.
The microwave method works in a pinch, but I’m partial to the oven-baked version – that golden-brown top with slightly crispy edges just can’t be beat. Let the casserole rest for about 5 minutes before serving to allow the flavors to settle and meld together.
Creamy Cheesy Chicken Green Bean Casserole Substitutions and Variations
Now that you’ve mastered the basic recipe, let’s explore some easy swaps and creative twists that’ll keep this casserole feeling fresh every time you make it.
Try using rotisserie chicken when you’re pressed for time—I’ve done this on busy weeknights and nobody can tell the difference.
Swap cheddar for pepper jack if you crave a kick, or mix in some Swiss for a nuttier flavor. Not a mayo fan? Greek yogurt works beautifully as a creamy substitute.
For veggie variations, toss in mushrooms before baking, or mix frozen corn with the green beans for a pop of color.
Trust me, this recipe forgives experimentation.
What to Serve with Creamy Cheesy Chicken Green Bean Casserole
While this hearty casserole can certainly stand on its own as a complete meal, pairing it with complementary sides elevates the entire dining experience.
I love serving a crisp garden salad with tangy vinaigrette to balance the creamy richness. Warm, crusty bread is perfect for sopping up that cheesy sauce—my family practically fights over the last piece.
For a more substantial spread, consider simple roasted potatoes or buttery rice pilaf.
And when I’m feeling fancy? A chilled white wine, maybe a Chardonnay or Sauvignon Blanc. The acidity cuts through the creaminess beautifully, and honestly, doesn’t everything taste better with wine?
Final Thoughts
After cooking this creamy, cheesy chicken green bean casserole countless times for my family, I’ve come to appreciate how it transforms ordinary ingredients into something truly special.

What I love most is its versatility. You can prep it ahead, customize the veggies, or even use leftover rotisserie chicken in a pinch.
