Hot Chicken Salad Casserole
Hot chicken salad casserole combines bite-size cooked chicken with mayonnaise, celery, Cheddar, almonds, lemon, and a little pimiento. It bakes in a shallow dish until the filling is hot and the potato-chip topping is golden. Rotisserie or leftover chicken works well: the oven heats the assembled casserole rather than cooking raw chicken. Serve it in loose, generous scoops that show the chunky chicken, almonds, and crisp topping.
Ingredients for Hot Chicken Salad Casserole

- 4 cups cooked chicken, cut into bite-size pieces (560g)
- 1 cup mayonnaise (225g)
- 1 cup finely chopped celery (100g)
- 1 cup shredded Cheddar cheese (110g)
- 1/2 cup sliced or slivered almonds (45g)
- 1/4 cup diced pimientos, drained and patted dry (30g; optional)
- 1 tablespoon fresh lemon juice
- 1/2 teaspoon kosher salt, or to taste
- 1/4 teaspoon black pepper
- 1 1/2 cups coarsely crushed potato chips (35g)
How to Make Hot Chicken Salad Casserole

- Prepare the oven and dish: Preheat the oven to 350°F (175°C). Lightly grease a shallow 9-by-13-inch casserole dish.
- Mix the filling: In a large bowl, stir together the mayonnaise, lemon juice, salt, and pepper. Fold in the cooked chicken, celery, Cheddar, almonds, and pimientos, if using. Mix gently so the chicken stays in bite-size pieces.
- Fill the dish: Spread the mixture evenly in the prepared dish. A shallow, even layer helps the center heat before the edges dry out.
- Add the topping: Scatter the coarsely crushed potato chips over the filling in a loose, even layer. Do not pack them down.
- Bake: Bake uncovered for about 25–30 minutes, beginning to check at 20 minutes. Remove the casserole when the edges are bubbling, the center is thoroughly hot, and the topping is golden rather than deeply browned.
- Rest and serve: Let stand for 5 minutes, then spoon generous, irregular scoops onto plates.
How to Tell When the Casserole Is Ready
A casserole assembled cold from the refrigerator or baked in a deeper dish may need more time. Check the center as well as the edges; a golden topping alone does not mean the filling is hot throughout. Once the edges bubble and the center is thoroughly hot, take it out rather than baking longer just to darken the chips. Extra time can dry the filling or overbrown the topping.
Ingredient and Topping Options
Pimientos add small red accents but can be left out. Drain and pat them dry, along with any other optional vegetables, so the filling stays creamy rather than watery.
- Fold in 1/2 cup drained, chopped water chestnuts for more crunch in the filling.
- Add 1/2 cup cooked, well-drained sliced mushrooms for a savory variation.
- Replace the potato chips with 1 to 1 1/2 cups French-fried onions or crushed buttery crackers.
Make-Ahead, Storage, and Reheating
To assemble ahead, cover the chicken mixture in the casserole dish and refrigerate it. Add the chips just before baking to keep them crisp. A cold casserole may need extra oven time; use the bubbling edges and hot center to judge when it is ready.
Refrigerate leftovers in an airtight container for up to 3 days. The topping will soften against the filling. Reheat leftovers covered in a 325°F (165°C) oven until hot throughout, or warm individual portions in the microwave. Serve with a green salad and bread, biscuits, or rolls.
Freezing is not the preferred storage method because thawing may change the texture of the creamy filling.
