  • 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

Step-by-Step Directions

Now that we have all our ingredients ready, let’s get to the fun part making this delectable casserole! Just follow these simple steps:

  1. Preheat your oven to 350°F (175°C). Grease a large casserole dish with a little butter or cooking spray to ensure nothing sticks.
  2. Cook the chicken in a large pot over medium heat for about 6-7 minutes per side until its surface turns golden brown and it’s cooked through.
  3. While the chicken is cooking, boil salted water in a separate pot and cook your spaghetti until it’s al dente, about 8-10 minutes. Once done, drain and set aside.
  4. In a big bowl, mix the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the cheddar cheese together until everything is well combined.
  5. Transfer this enticing mixture to your greased casserole dish. Top it off with the remaining cheese to create that bubbly, melted cap.
  6. Bake in your preheated oven for 25-30 minutes, until everything is bubbly, and the top is a gorgeous golden brown.
  7. Finally, let it rest for about 5 minutes before garnishing with chopped green onions and serving.

A side note: Don’t overmix when you’re combining the ingredients. We want tender crumbs tough dough is a no-go!
