Ingredients

3 cups chicken, cooked and shredded (or diced)
1 cup green beans (or veggie of choice)
1 cup cheddar cheese, shredded
1/2 cup sour cream
1/4 cup mayonnaise
1 can cream of chicken soup
1/4 cup almonds, slivered
6 oz. French fried onions

Instructions

Step 1: Preheat oven to 400 degrees and spray a 9 x 13 baking pan with cooking spray.
Step 2: In a bowl, combine the cooked chicken, green beans, cheddar cheese, sour cream, mayonnaise, cream of chicken soup, and slivered almonds. Mix well.
Step 3: Spread the chicken mixture evenly into the prepared baking pan.
Step 4: Place the pan in the oven and bake for 30 minutes.
Step 5: Remove from the oven and sprinkle the French fried onions evenly on top.
Step 6: Return the pan to the oven and bake an additional 5–8 minutes, or until the onions are golden brown.
Step 7: Remove from the oven and serve warm.

Tips & Variations

Swap green beans for broccoli or asparagus to change up the flavor and texture.
For extra creaminess, stir in a little cream cheese with the sour cream and mayo.
Use smoked cheddar for a richer, slightly smoky taste.
Soak the slivered almonds in warm water for 10 minutes if you prefer a softer nut texture.
Add garlic powder or onion powder to enhance the French onion flavor.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350 degrees until warmed through for best texture. The fried onions may lose some crunch when refrigerated, so you can add fresh onions on top before serving again if desired.
