How to Make Chicken & Swiss Casserole

Preheat the oven to 350°F (175°C) to get it nice and hot, perfect for baking your casserole to golden perfection.
Cook the egg noodles according to the package instructions, then drain them and set aside. You want them al dente for the best texture!
Heat olive oil in a large skillet over medium heat. Add the chopped shallots and minced garlic, then sauté for about 45 seconds until they’re fragrant and slightly softened.
Stir in the flour, cooking it for about 1 minute until bubbly, then gradually whisk in the chicken broth and milk until the mixture is smooth and thickens slightly.
Incorporate the dried thyme, lemon zest, salt, nutmeg, and pepper into the sauce. Stir until everything is well combined and heated through, about 2-3 minutes.
Add the cubed rotisserie chicken and frozen peas to the skillet, mixing them gently. Then, fold in the cooked noodles and shredded Swiss cheese until everything is coated and combined.
Transfer the mixture to a greased 13×9-inch baking dish, spreading it evenly to ensure even baking.
Combine breadcrumbs with melted butter in a separate bowl, then sprinkle this crunchy topping evenly over the casserole for that perfect crispy finish.
Bake for 8-10 minutes until the top is golden brown and crispy, and the filling is bubbling deliciously.

Optional: Garnish with fresh parsley for a vibrant pop of color.

Absolutely! Regular egg noodles provide the perfect texture and structure for this Chicken & Swiss Casserole. If you want a healthier alternative, whole grain pasta works wonderfully too!

How should I store leftover Chicken & Swiss Casserole?
The more the merrier with leftovers! Store your casserole in an airtight container in the refrigerator for up to 3 days. Make sure it’s cooled completely before putting it away. Just reheat it in the oven or microwave, and it’ll taste almost as good as the first time!

Can I freeze this casserole, and if so, how?
Definitely! To freeze your Chicken & Swiss Casserole, prepare it as directed but do not bake it. Tightly cover the unbaked casserole with plastic wrap and then foil to keep it airtight, and it can last for up to 2 months in the freezer. When you’re ready to enjoy it, thaw it overnight in the fridge and bake at 350°F (175°C) for about 25-30 minutes until it’s heated through.

What should I do if my casserole is too dry after baking?
No worries! If your casserole comes out a bit dry, this can happen if it’s overcooked. I recommend keeping an eye on it while baking and checking for doneness a few minutes early. If you find it’s already dry, try adding a splash of chicken broth or milk on top before reheating to bring back some moisture.

Are there any dietary considerations for this casserole?
Very good question! This Chicken & Swiss Casserole can be easily adapted to suit various dietary needs. Substitute the all-purpose flour with a gluten-free blend for those with gluten sensitivities. For dairy-free options, use nut milk and dairy-free cheese alternatives.
