Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with nonstick spray or butter.
Bring a large pot of salted water to a boil. Cook the egg noodles according to package instructions until al dente. Drain and set aside.
In a large mixing bowl, whisk together the cream of mushroom soup and milk until smooth.
Add the drained tuna, frozen peas, 1 1/2 cups of shredded cheddar cheese, salt, and pepper to the soup mixture. Stir until well combined.
Gently fold in the cooked egg noodles, ensuring they are evenly coated in the mixture.
Pour the noodle mixture into the prepared casserole dish, spreading it into an even layer.
Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top.
In a small bowl, combine the crushed potato chips and melted butter, stirring to coat evenly. Sprinkle this mixture evenly over the casserole.
Bake the casserole in the preheated oven for 25–30 minutes, or until the top is golden brown and the mixture is bubbling around the edges.
Remove the casserole from the oven and let it cool for 5 minutes before serving. Enjoy!
