How to Make Cheesy Chicken Casserole
- Preheat Your Oven: Begin by preheating your oven to 375°F. This ensures a perfect bake for your casserole.
- Cook the Pasta: Boil the medium shells in salted water until al dente, following the package instructions. This allows the pasta to hold its shape as it bakes.
- Sauté the Veggies: In a skillet, melt the 3 tablespoons of butter over medium heat. Add the finely diced onion and diced red bell pepper; sauté for about 5 minutes, or until they are tender and fragrant. Stir in the teaspoon of chili powder and seasoned salt, mixing well.
- Combine Ingredients: In a large bowl, combine the condensed cream of chicken soup, sautéed onion mixture, 1⅓ cups milk, 2 cups of shredded sharp cheddar cheese, and the parmesan cheese. Mix everything together until smooth. Fold in the cooked chicken pieces, canned mild green chiles, and the cooked pasta shells until evenly coated.
- Assemble the Casserole: Spread the mixture into a greased 9×13 casserole dish. Make sure to distribute it evenly, then sprinkle the remaining shredded cheddar cheese on top for that irresistible, melty finish.
- Bake: Place your casserole in the preheated oven and bake for 30 to 35 minutes, or until it is hot and bubbly around the edges, and the top is slightly golden.
Storing & Reheating
Store any leftovers at room temperature for a few hours if they remain on the table. For longer storage, transfer to an airtight container and refrigerate, where it will stay fresh for up to three days. If you want to keep it longer, you can freeze the casserole for up to three months. When ready to eat, reheat in the oven at 350°F for about 20-25 minutes or until warmed through. Be aware that the texture may change slightly, but a sprinkle of fresh cheese on top can refresh its appeal!
Chef’s Helpful Tips
- Keep an eye on the pasta; if overcooked, it may become mushy in the casserole.
- For an extra creamy texture, use extra cheese or substitute with cream instead of milk.
- You can easily make this dish a day ahead. Just prepare it up to the baking step, cover, and refrigerate. Bake just before serving.
- If you want a bit of crunch, consider topping the casserole with breadcrumbs or crushed crackers in the last 10 minutes of baking.
