The key to this dish lies in selecting the right ingredients that bring both comfort and a touch of heat. I always reach for fresh, high-quality produce and proteins — it’s amazing how much difference that makes in simple recipes like this one. For the creamy base, I prefer whole milk or half-and-half to keep things rich without feeling heavy. And when it comes to the spice, I like to use a combination of cayenne and smoked paprika to add warmth and depth without overpowering the other flavors.

  • 12 ounces spaghetti, cooked al dente
  • 2 cups cooked, shredded chicken (rotisserie chicken works great)
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 1 cup diced tomatoes with green chilies (like Ro*Tel)
  • 1 cup shredded sharp cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 1 cup heavy cream or half-and-half
  • 1/2 cup sour cream
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cayenne pepper (adjust to taste)
  • 1 teaspoon dried oregano
  • Salt and black pepper to taste
  • 2 tablespoons olive oil or butter for sautéing
  • Optional: chopped green onions or fresh cilantro for garnish

If you’re short on time, using pre-cooked chicken or even leftover roast chicken is a great shortcut. For a milder version, simply reduce the cayenne or omit it altogether — this dish adapts well to your family’s heat tolerance.

Instructions

  1. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Cook the spaghetti according to package instructions until just al dente. Drain and set aside.
  3. Heat olive oil or butter in a large skillet over medium heat. Add chopped onion and sauté until translucent, about 4 minutes.
  4. Add minced garlic and cook for another 30 seconds until fragrant.
  5. Stir in the diced tomatoes with green chilies, smoked paprika, cayenne pepper, oregano, salt, and pepper. Let the mixture simmer for 3-4 minutes to meld the flavors.
  6. In a large mixing bowl, combine the cooked spaghetti, shredded chicken, tomato mixture, heavy cream, sour cream, and half of the shredded cheeses. Mix gently until everything is well coated.
  7. Transfer the mixture to your prepared baking dish and sprinkle the remaining cheese evenly on top.
  8. Bake uncovered for 20-25 minutes, or until the cheese is bubbly and golden brown on top.
  9. Remove from oven and let the casserole rest for 5 minutes before serving. Garnish with chopped green onions or cilantro if desired.
