This Tex Mex Chicken Noodle Casserole is a creamy, cheesy, crowd-pleasing dinner made with tender chicken, pasta, and bold taco-inspired flavors. Finished with a crispy corn chip topping, it’s an easy, family-friendly meal that comes together quickly and bakes up perfectly every time.
Preheat the oven to 375°F. Lightly grease a 9x13 baking dish.
Cook the egg noodles according to package directions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add the onion and bell pepper and cook until softened.
In a large mixing bowl, combine the cooked noodles, onion, bell pepper, shredded chicken, corn, black beans, diced tomatoes with green chiles or salsa, and taco seasoning, sour cream, and 1½ cups of the shredded cheese. Stir until well combined.
Pour the mixture into the prepared baking dish and spread evenly.
Top with the remaining ½ cup cheese and sprinkle the Fritos evenly over the top.
Bake for 30 minutes until hot and bubbly and the cheese is melted.
Let cool for about 10 minutes before serving.
Sprinkle sliced green onions over the top just before serving.
Serve warm as a complete meal or with a simple side salad.
Notes
Grease with melted butter or cooking spray. Make sure your baking dish is well-greased so nothing sticks and every scoop comes out clean. Butter adds a little extra flavor, but spray works just fine for ease!
Cook noodles just to al dente. The noodles will continue cooking in the oven, so keeping them slightly firm prevents a mushy casserole.
Drain the ingredients well. Be sure to drain the tomatoes, corn, and beans thoroughly so you don’t end up with a watery casserole!
Use freshly shredded cheese. I always recommend using freshly shredded cheese from a block if you can. It melts more consistently and doesn’t become grainy. However, if pre-shredded cheese is all you have on hand, you can use that!
Let it rest before serving! Allow the casserole to cool for about 10 minutes after baking. This helps everything set up so it’s easier to scoop and serve.
