1-Getting this spicy southern chicken spaghetti casserole just right starts with simple steps that anyone can follow, even if you’re new to cooking. Begin by preheating your oven to 350 degrees Fahrenheit to ensure even baking. Melt the 1 tablespoon butter in a large nonstick pan and cook the chopped medium sweet onion until soft, about 4 to 5 minutes, for a flavorful base.

2-Next, add the 1/2 teaspoon seasoned salt, 1/2 teaspoon garlic powder, 1 can condensed cream of chicken soup, 1 (10-ounce) can diced tomatoes with green chilies, 1 pound cheese product cut into cubes, and 1/3 cup milk. Stir constantly until the cheese melts, creating a creamy sauce. Then, fold in the 3 cups chopped cooked chicken and season with black pepper to taste for that extra kick.

3-Mix in the 12 ounces cooked spaghetti and transfer the mixture into a greased 9×13-inch casserole dish. Cover with aluminum foil and bake for 20 minutes. Remove the foil, sprinkle the 1 cup shredded cheddar cheese on top, and bake uncovered for another 5 minutes until golden.
