Main Ingredients

  • 1.5 lbs boneless, skinless chicken breasts (about 3-4 pieces) Use fresh chicken for the best flavor! Alternatively, rotisserie chicken is a fantastic shortcut.
  • 8 oz spaghetti Whole wheat or gluten-free pasta works wonderfully for a healthier option.
  • 2 cups shredded sharp cheddar cheese Sharp cheddar gives this casserole its rich, cheesy flavor.
  • 1 cup fresh bell peppers (chopped) A mix of red, yellow, and green bell peppers adds flavor and visual appeal.
  • 1 can (10.5 oz) cream of chicken soup This creamy goodness binds everything together.
  • 1 tsp paprika Use smoked paprika for an extra depth of flavor.
  • 1/2 tsp cayenne pepper Adds just the right amount of heat.
  • 1 tsp garlic powder Fresh garlic can be sautéed with the chicken for added aroma.
  • 1/4 cup green onions (sliced) Perfect for garnishing at the end.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • Grease a large casserole dish. In a large pot over medium heat, cook the chicken for about 6-7 minutes per side until golden and cooked through.
  • While the chicken cools, boil salted water in a separate pot and cook your spaghetti until al dente (about 8-10 minutes). Drain and set aside.
  • In a big mixing bowl, shred the cooked chicken and mix it together with the cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the shredded cheddar cheese.
  • Pour the mixture into your greased casserole dish and spread it out evenly. Top with the remaining cheese.

Baking

  • Bake for 25-30 minutes until bubbly and the cheese is golden brown.
  • Let it rest for about 5 minutes before garnishing with chopped green onions and serving.

Notes

You can assemble the casserole a day in advance. Store leftovers in an airtight container for up to 3 days. Casserole can be frozen for up to 2 months if not baked.
