How to Make Swiss Chicken Casserole

Step 1: Prepare the Chicken

Start by cutting the chicken breasts into bite-sized pieces or thin strips. Season with salt and pepper, then lightly sauté in butter over medium heat until golden and just cooked through. Set aside to keep warm while preparing the sauce.

Step 2: Sauté the Vegetables

In the same pan, add diced onions and sliced mushrooms. Cook until soft and fragrant, about 5 minutes. Add minced garlic during the last minute to enhance the aroma without burning it.

Step 3: Make the Creamy Sauce

Sprinkle flour over the vegetables and stir to combine, forming a roux. Slowly whisk in the chicken broth and heavy cream, stirring until the mixture thickens smoothly. Season with salt, pepper, and fresh thyme, then remove from heat.

Step 4: Combine and Assemble

Mix the cooked chicken back into the creamy sauce, then pour everything into a greased casserole dish. Top generously with shredded Swiss cheese, and if desired, sprinkle with panko breadcrumbs for crunch.

Step 5: Bake Until Bubbly

Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the top is golden and the casserole is bubbling hot. Let it rest for a few minutes before serving to allow flavors to meld.

Pro Tips for Making Swiss Chicken Casserole

• Use fresh cheese: Grate your own Swiss cheese for better melt and flavor than pre-shredded varieties.
• Don’t overcook chicken: Slightly undercook the chicken during sautéing as it will continue to cook in the casserole.
• Enhance mushroom flavor: Use cremini or baby bella mushrooms for a richer, earthier taste.
• Let it rest: Allow the casserole to rest 5-10 minutes after baking for creaminess to settle.
• Use fresh herbs: Add fresh parsley or thyme right before serving for a burst of freshness.

How to Serve Swiss Chicken Casserole

Storing Leftovers

Let the casserole cool completely before transferring to airtight containers. It keeps well in the fridge for up to 3 days, making it a great meal prep option.

Freezing

You can freeze Swiss Chicken Casserole for up to 2 months. For best results, freeze before baking and thaw overnight in the fridge before cooking.

FAQs

Can I use frozen chicken for this casserole?

Is there a vegetarian version of Swiss Chicken Casserole?

Absolutely! You can replace the chicken with hearty vegetables like eggplant or cauliflower and use vegetable broth to keep the same creamy, comforting feel.

Can I make this gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend and replace panko breadcrumbs with gluten-free alternatives to keep it safe for gluten-sensitive diets.

What’s the best cheese substitute if I don’t have Swiss cheese?

Gruyere, mozzarella, or even fontina are excellent choices, providing similar melting qualities and mild flavor that complement the casserole well.
