Ingredients

12 oz spaghetti, cooked al dente
2 cups cooked shredded chicken (rotisserie or homemade)
1 tablespoon olive oil
1 small onion, finely chopped
1 bell pepper, diced
1 can (10 oz) diced tomatoes with green chilies, drained
1 can (10.5 oz) cream of chicken soup
1 cup sour cream
2 cups shredded cheddar cheese (divided)
½ teaspoon smoked paprika
¼ teaspoon cayenne pepper (optional for extra heat)
Salt and black pepper to taste
Fresh parsley for garnish

Step-by-Step Instructions

Preheat the oven Set your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with olive oil or nonstick spray.
Sauté the veggies In a large skillet, heat olive oil over medium heat. Add chopped onion and bell pepper. Cook until soft and fragrant, about 4–5 minutes.
Mix the sauce In a large bowl, combine the sautéed vegetables, cream of chicken soup, sour cream, diced tomatoes with green chilies, half the shredded cheese, and spices. Stir until creamy and well blended.
Combine with chicken and spaghetti Add cooked spaghetti and shredded chicken to the creamy mixture. Toss gently to coat every strand in that luscious sauce.
Bake until bubbly Transfer everything into the prepared casserole dish. Top with the remaining cheese and bake uncovered for 25–30 minutes, until hot and bubbly with golden edges.
Serve & enjoy Garnish with fresh parsley and serve warm. Pair it with a side salad or roasted veggies for a comforting Southern-style dinner.

Variations to Try

Mild version: Skip the cayenne and use plain diced tomatoes instead of spicy ones.
Extra spicy: Add chopped jalapeños or a dash of hot sauce to the sauce mixture.
Veggie boost: Stir in chopped spinach, mushrooms, or zucchini for a wholesome twist.
Cheese lovers’ dream: Mix in Monterey Jack or pepper jack for even more melty indulgence.

Tips from Chef Emma

Cook spaghetti just until al dente—it will continue to soften as it bakes.
Shred your own cheese for the best melt and flavor.
Use rotisserie chicken for a quick, flavorful shortcut.
Let the casserole rest 10 minutes before serving so it holds its shape beautifully.
