Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente. Drain and set aside, tossing with a little olive oil to prevent sticking.

Step 2: Prepare the Chicken and Sauce

In a large skillet, melt the butter over medium heat. Add the cooked, shredded chicken and season with garlic powder, onion powder, Italian seasoning, red pepper flakes (if using), salt, and black pepper. Stir for 2 minutes until the chicken is well coated with the seasonings.

Pour in the marinara sauce and heavy cream (or milk), stirring to combine. Let the sauce simmer for about 3–5 minutes until it thickens slightly.

Step 3: Combine Pasta and Sauce

Add the drained spaghetti to the skillet with the creamy marinara chicken mixture. Toss everything together until the pasta is fully coated and evenly mixed.

Step 4: Assemble and Add Cheese

Preheat your oven to 375°F (190°C). Transfer the spaghetti mixture to a greased 9×13-inch baking dish. Sprinkle the shredded mozzarella, cheddar, and Parmesan cheese evenly over the top.

---

Step 5: Bake to Perfection

Place the dish in the preheated oven and bake uncovered for 15–20 minutes, or until the cheese is fully melted, bubbly, and golden brown on top.

Step 6: Garnish and Serve

Remove from the oven and let it sit for a few minutes. Garnish with freshly chopped parsley and serve hot. Enjoy your ultimate cheesy chicken spaghetti!

Storage Instructions

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, place the spaghetti in a microwave-safe dish and heat in 30-second intervals until warmed through. Alternatively, reheat in the oven at 350°F (175°C) for about 15 minutes. If the pasta seems dry, add a splash of milk or marinara sauce before reheating.

For longer storage, you can freeze the dish. Wrap it tightly in plastic wrap and aluminum foil, then freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.
