Step-by-Step Instructions
- Prepare the Oven and Dish:
- Preheat your oven to 350 degrees Fahrenheit. Lightly grease a large casserole dish to prevent sticking and make cleanup easier. Getting this ready ahead saves time later.
- Cook the Chicken:
- Place the chicken breasts in a large pot over medium heat. Cook for six to seven minutes per side until golden and cooked through. The inside should be moist without any pink. Let the chicken cool slightly then shred into bite-sized pieces using forks or your hands.
- Boil the Spaghetti:
- Bring a large pot of salted water to a boil. Add the spaghetti and cook until just al dente about eight to ten minutes. Drain well and set aside. The noodles should be firm enough to absorb sauce without becoming mushy.
- Mix the Casserole Base:
- In a big mixing bowl combine the shredded chicken cooked spaghetti cream of chicken soup chopped bell peppers paprika cayenne garlic powder and half of the cheddar cheese. Stir until everything is evenly coated and the cheese starts to blend into the mixture.
- Assemble and Bake:
- Pour the mixture into the prepared casserole dish and spread it out evenly. Sprinkle the remaining cheddar cheese over the top. Bake in the oven for 25 to 30 minutes until bubbly and the cheese is golden and crisp on top.
- Rest and Serve:
- Once out of the oven allow the casserole to rest for five minutes so it firms up and slices neatly. Garnish with sliced green onions for added color and fresh brightness. Serve warm and enjoy.
Sharp cheddar cheese is my favorite ingredient here because its tang cuts through the creamy sauce beautifully. Growing up I loved helping my mom grate the cheese and sneak small tastes of the sharp edges right off the block. Nothing replaces fresh shredded cheese for that perfect melt and flavor boost.
Storage Tips
Store any leftovers in an airtight container in the fridge for up to three days. The flavors deepen as it sits making it even better the next day. When reheating cover the casserole and warm it gently in a 325-degree Fahrenheit oven to keep the cheese melty and the pasta from drying out.
Ingredient Substitutions
If cheddar is not available try Monterey Jack for a milder melt or pepper Jack for a bit more spice. Gluten-free pasta works well for dietary needs. Feel free to add other veggies like diced poblano peppers or fresh spinach for extra color and nutrition. Rotisserie chicken is a timesaver option that adds great flavor and convenience.
Serving Suggestions
Serve hearty squares of the casserole with a crisp green salad and warm garlic bread to balance the richness. For a fun twist try topping with salsa or a dollop of sour cream. This dish is also great for brunch gatherings or enjoying as leftovers for lunch the next day.
