When you need a big pan of comfort food, this Traeger Cheesy Chicken Casserole is the perfect fit. Tender grilled chicken is cubed up and mixed into this one-pan meal that cooks in the pellet grill and has so much cheese, it should almost be illegal.
Traeger Smoked Cheesy Chicken Casserole
I grew up in the Midwest, so you can imagine how hard it was for me NOT to call this a Chicken Hot Dish. It should be called that, by all rights, but it lacks the standard “cream of” soups that are so common in all things hot dish that casserole seemed more appropriate. There are no “cream of” soups in this recipe, just real ingredients put together in a simple way to make something that is greater than all the parts.
This homemade cheesy chicken casserole was just what we needed after a long day. It was done in under an hour, we only dirtied two dishes, and who doesn’t love noodles + cheesy + big chunks of chicken all in a savory, homemade sauce?
We kept it simple this time and served this with a big green salad, but there’s nothing stopping you from throwing in a whole bunch of vegetables while this cooks. Some lightly steamed broccoli would be perfect, and if you’re into a little crunchy topping this could really benefit from a sleeve of butter crackers crushed up and sprinkled on top. You do you.
This recipe calls for so much Better Than Bouillon you’d think they were paying me to say this, but they aren’t (so far! I’m not opposed, wink wink)! We use this stuff ALL THE TIME in our kitchen and when I saw all the new varieties they were coming out with, I grabbed them all.
If you don’t have them, can’t find them, or would rather not use them, you can sub in chicken stock, fresh mushrooms (or mushroom powder), fresh garlic, and fresh or dried Italian Herbs like basil, oregano, and thyme into the mix. This recipe is very forgiving, so add a little of this and a little of that and experiment!

Make a butter roux and then make the rest of the sauce. Let it simmer until it thickens slightly. Remove from the heat and stir in the cream. Set aside.
Mix the uncooked noodles, chicken, most of the cheese, and the sauce together in a grill-safe baking dish. Pour the sauce over and put on the grill.
In the pellet grill, that is. Cook for 20 minutes and then check it and give it a stir. Toss in the rest of the cheese and let it finish cooking.

Homemade Cheesy Chicken Casserole FAQ
Can you make this in the oven?
Yes! This recipe works great in the oven too. You can even make it on the stovetop if you don’t feel like firing up the pellet grill OR the oven.
What’s the best way to store and reheat leftovers?
Cover the leftovers with foil and store in the fridge for 4-5 days, max. Reheat in the microwave, but don’t overdo it! The noodles will get mushy.
Can you use another type of noodle?
I prefer egg noodles with this recipe, but in theory you could sub in another type.

- 1/2 cup salted butter
- 1/3 cup all-purpose flour
- 6 cups water
- 4 teaspoons Better Than Bouillon Chicken
- 1 teaspoon Better Than Bouillon Garlic
- 1 teaspoon Better Than Bouillon Italian Herbs
- 1 teaspoon Better Than Bouillon Mushroom
- 1/2 teaspoon pepper
- 1/2 teaspoon onion powder
- 1 cup whipping cream
- 16-ounce bag extra-wide egg noodles
- 4 cups diced cooked chicken
- 16-ounces shredded cheese (we use the Kraft Triple Cheddar variety a lot)
- 1 teaspoon fresh chopped parsley
- Preheat the grill to 350°F.
- In a large saucepan or Dutch Oven, melt the butter over medium-low heat. Whisk in the flour and cook for 3-4 minutes, stirring frequently.
- Whisk in the water and all of the bouillons along with the pepper and onion powder. Increase the heat to medium or medium-high, and bring to a simmer. Whisk frequently until the mixture has thickened.
- Remove from heat and stir in the cream.
- In a large 10x13 inch high-sided grill-safe baking pan that's been lightly sprayed with cooking spray, dump in the uncooked egg noodles, cooked chicken, and 3/4 of the shredded cheese. Pour the sauce over the top and give it a little stir to make sure all the noodles are mostly submerged.
- Put the dish into the preheated grill and let cook for 20 minutes. Check and stir, and test the doneness of the noodles. Top with the rest of the cheese and cook until the noodles are tender and the cheese is melted. Chances are the noodles will be tender already, but your mileage may vary!
- Remove from the grill and sprinkle with fresh parsley. Serve hot with crusty bread and fresh salad.
