2 cups shredded sharp cheddar cheese
1 cup fresh bell peppers, chopped
1 can (10.5 oz) cream of chicken soup
1 tsp paprika
½ tsp cayenne pepper
1 tsp garlic powder
¼ cup green onions, sliced (for garnish)
Preheat oven to 350°F (175°C).
Grease a large casserole dish with butter or cooking spray.
In a large pot or skillet over medium heat, cook chicken 6–7 minutes per side until golden and fully cooked.
Remove chicken and shred or chop into bite-sized pieces.
Boil salted water and cook spaghetti until al dente (8–10 minutes).
Drain and set aside.
In a large bowl, mix together:
Shredded chicken
Cooked spaghetti
Cream of chicken soup
Chopped bell peppers
Paprika, cayenne, garlic powder
Half of the cheddar cheese
Transfer mixture into the greased casserole dish.
Top with the remaining cheddar cheese.
Bake 25–30 minutes until bubbly and golden brown.
Let casserole rest 5 minutes before serving.
Garnish with sliced green onions and enjoy!
Cook spaghetti al dente: It will absorb flavors without getting mushy.
Customize the spice: Adjust cayenne pepper to your heat preference.
Add extra veggies: Mushrooms, zucchini, or corn work well.
Make ahead: Assemble the casserole the night before and refrigerate; bake before serving.
