With just a handful of steps, you’ll have a mouth-watering dish ready to bake in the oven.
What you’ll need
Gather up these ingredients to get started on your Spicy Southern Cheesy Chicken Spaghetti Casserole:
- 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)
Note: Feel free to substitute the cream of chicken soup with a homemade béchamel if you prefer a from-scratch route.
Step-by-step instructions
- Preheat your oven to 350°F (175°C) and grease a large casserole dish.
- In a large pot, cook the chicken over medium heat for about 6-7 minutes per side or until it’s golden brown and completely cooked through.
- While the chicken cooks, bring a pot of salted water to a boil and cook the spaghetti until al dente, usually around 8-10 minutes. Drain and set aside.
- In a mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the cheddar cheese. Stir until everything is well mixed.
- Transfer the mixture to your greased casserole dish and sprinkle the remaining cheese on top.
- Bake for 25-30 minutes, or until it’s bubbly and the top is golden brown.
- Allow it to rest for 5 minutes, then garnish with sliced green onions before serving.
