Spicy Southern Cheesy Chicken Spaghetti Casserole

Why You’ll Love This Recipe

I love this recipe because it is easy to make, filling, and packed with cheesy comfort. I get tender chicken, creamy sauce, sharp cheddar, and a gentle spicy kick from paprika and cayenne pepper in every bite.

I also like that this casserole serves a crowd without needing complicated steps. I can prepare it in about 45 minutes, and it comes out bubbly, golden, and ready to serve.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

3-4 boneless, skinless chicken breasts, about 1.5 lbs
8 oz spaghetti
2 cups shredded sharp cheddar cheese
1 cup fresh bell peppers, chopped
1 can, 10.5 oz, cream of chicken soup
1 tsp paprika
1/2 tsp cayenne pepper
1 tsp garlic powder
1/4 cup green onions, sliced

Directions

I preheat the oven to 350°F, then grease a large casserole dish.

I cook the chicken in a large pot over medium heat for about 6-7 minutes per side, until it is golden and cooked through.

I boil salted water and cook the spaghetti until al dente, about 8-10 minutes. Then I drain it and set it aside.

I shred the cooked chicken, then mix it in a bowl with the cooked spaghetti, cream of chicken soup, bell peppers, paprika, cayenne pepper, garlic powder, and half of the cheddar cheese.

I transfer the mixture to the greased casserole dish and top it with the remaining cheddar cheese.

I bake it for 25-30 minutes, until the casserole is bubbly and golden brown.

I let it rest for 5 minutes, then garnish it with sliced green onions before serving.

Variations

I sometimes add diced tomatoes with green chiles for extra Southern flavor. I can also use rotisserie chicken when I want a faster version.

For more heat, I add extra cayenne pepper or sliced jalapeños. For a milder casserole, I reduce the cayenne and use sweet bell peppers.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 3-4 days.

To reheat, I warm individual portions in the microwave until hot. For larger portions, I cover the casserole dish with foil and reheat it in the oven at 350°F until warmed through.
