How to Make Chicken Salad Soufflé Casserole Recipe
Step 1: Preheat and Prep
Start by heating your oven to 350°F (175°C) and greasing a medium casserole dish. This prep ensures your soufflé casserole will cook evenly and won’t stick, setting the stage for a perfectly golden finish.
Step 2: Create the Chicken Salad Base
In a large mixing bowl, combine the chopped chicken, celery, mayonnaise, lemon juice, onion powder, and a pinch of salt and pepper. Stir everything together thoroughly, so every bite is bursting with blended flavors and contrasting textures. Then, spread this mixture evenly across the bottom of your prepared casserole dish.
Step 3: Prepare the Soufflé Topping
Whisk the egg yolks with the heavy cream until smooth, then fold in the shredded cheddar cheese. The cheese helps the soufflé develop a rich, custardy depth of flavor. In a separate bowl, beat the egg whites until stiff peaks form—this is key to achieving a light, airy soufflé. Gently fold the egg whites into the yolk and cheese mixture, taking care to keep as much air as possible for that classic rise.
Step 4: Assemble the Casserole
Now, carefully spoon the fluffy soufflé topping over the chicken salad base. Spread it out evenly to create a smooth surface that will bake beautifully golden and puffed up.
Step 5: Bake to Perfection
Place your casserole in the oven and bake uncovered for 30 to 35 minutes. You’ll know it’s done when the top is a lovely golden brown and puffed high – it should look light yet invitingly set.
Step 6: Rest and Serve
Let your Chicken Salad Soufflé Casserole rest for a few minutes after baking. This step allows the structure to settle a bit, making it easier to slice and serve while still warm, ensuring maximum flavor and the perfect creamy texture.

Garnishes
Simple garnishes like freshly chopped parsley or a sprinkle of extra shredded cheddar cheese enhance both the look and the taste of this casserole. A few sprigs of thyme or a light dusting of paprika can add a wonderful pop of color that invites smiles around the table.
Side Dishes
This comforting casserole pairs wonderfully with fresh, crisp side salads or steamed green vegetables such as asparagus or green beans. For a heartier meal, serve it alongside buttery mashed potatoes or a warm crusty bread to soak up every last bit of that creamy topping.
Creative Ways to Present
Serve this Chicken Salad Soufflé Casserole recipe in individual ramekins for an elegant touch at dinner parties, or layer it in a trifle dish for a fun twist in presentation. You can even accompany it with a colorful fruit chutney or a tangy cranberry sauce for a flavor contrast that’s surprisingly delightful.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers covered in the refrigerator for up to 3 days. The flavors will deepen overnight, making the casserole taste even better the next day.
Freezing
This souffle casserole freezes well if you want to prepare it in advance. Wrap tightly in plastic wrap and aluminum foil to avoid freezer burn, and freeze for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat leftovers gently in the oven at 325°F (165°C) until warmed through, about 15-20 minutes. Avoid microwaving if possible, as the soufflé topping can lose its fluffy texture and become rubbery.
FAQs
Can I use leftover chicken for this recipe?
Absolutely! Leftover cooked chicken is perfect for this casserole and can add extra flavor, especially if it’s seasoned. Just be sure it’s chopped into bite-sized pieces for even mixing.
Is there a substitute for mayonnaise?
If you prefer, you can substitute Greek yogurt or sour cream for mayonnaise to reduce fat and add a bit of tang, but keep in mind this will slightly alter the texture and flavor.
Can I make this casserole dairy-free?
It’s a bit tricky since both the cheese and heavy cream are essential for the soufflé topping’s texture and taste. However, you can experiment with dairy-free cream and cheese alternatives, though results may vary.
What if my egg whites don’t form stiff peaks?
Make sure your mixing bowl and beaters are clean and dry, and your eggs are at room temperature. Any fat or moisture can prevent the whites from whipping properly.
How do I know when the soufflé casserole is done baking?
The top should be golden brown, puffed up, and slightly firm to the touch, but still tender inside. Avoid opening the oven too early, as this can cause it to collapse.
Final Thoughts
There’s something truly special about the way a Chicken Salad Soufflé Casserole Recipe combines familiar comfort with an elegant soufflé twist.
