How to Make Swiss Chicken Casserole with Panko

Step 1: Prepare the chicken and mushrooms

Start by slicing the chicken breasts into bite-sized pieces for even cooking. Sauté the mushrooms in a little butter until tender and golden to bring out their savory flavor before combining with the chicken.

Step 2: Mix the creamy base

In a large mixing bowl, combine sour cream, Swiss cheese, garlic powder, onion powder, salt, and pepper. Stir until the mixture is smooth and ready to gently coat the chicken and mushrooms.

Step 3: Combine and layer

Fold the sautéed chicken and mushrooms into the creamy mixture, making sure every piece is well-coated with cheesy goodness. Then transfer everything into a greased casserole dish, spreading it out evenly.

Step 4: Add the panko topping

Mix panko breadcrumbs with melted butter until all crumbs are lightly coated, then sprinkle generously over the top of the casserole. This step ensures that irresistible golden crunch.

Step 5: Bake to perfection

Bake the casserole in a preheated oven at 350°F (175°C) for about 30 minutes or until the topping is browned and crispy and the casserole bubbles at the edges.

Pro Tips for Making Swiss Chicken Casserole with Panko

• Even cooking: Cut chicken pieces uniformly so they cook at the same rate for tender results.
• Crispy topping hack: Toast the panko lightly in butter before topping for extra crunch and flavor.
• Cheese distribution: Layer some cheese inside the mixture and sprinkle a bit on top for cheesy layers.
• Use fresh ingredients: Fresh mushrooms and quality Swiss cheese make a noticeable difference.
• Don’t skip seasoning: Properly season the creamy base to ensure balanced flavor throughout the casserole.

Make Ahead and Storage

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 3 days. Storing it properly helps maintain the creamy texture and prevents the panko topping from becoming soggy.

Freezing

This casserole freezes well! Cover tightly with foil or plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for 15–20 minutes to restore the crispy panko topping; microwave reheating may soften the crunch.

FAQs

Can I use chicken thighs instead of breasts?

Is it possible to make this casserole dairy-free?

Yes, swap out Swiss cheese and sour cream for dairy-free cheese and coconut or almond-based sour cream alternatives to maintain creaminess.

How do I make the panko topping extra crispy?

Mix panko with melted butter before sprinkling and place the casserole under the broiler for the last 2–3 minutes, watching closely to prevent burning.

Can I prepare this recipe ahead of time?

You can assemble the casserole a day in advance, cover it tightly, and refrigerate. Simply bake it fresh when you’re ready to serve.

What type of Swiss cheese works best?

Look for classic Emmental or Gruyère varieties; both melt beautifully and provide that signature mild, nutty flavor.
