How to Make Chicken Spaghetti Casserole Step-by-Step

Step 1 – Cook the Chicken

Start by slicing your chicken breasts in half horizontally to make four thin cutlets. This helps them cook faster and more evenly. Heat olive oil in a skillet over medium heat and sear each piece for 7–10 minutes, flipping halfway until golden and cooked through. Once done, let the chicken rest to keep it juicy, then chop it into bite-sized pieces.

Step 2 – Cook the Spaghetti

Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook until just al dente—firm but cooked. This ensures the pasta won’t turn mushy during baking. Drain and set it aside.

Step 3 – Build the Sauce

Using the same skillet, melt the butter over medium heat. Toss in the diced onion and garlic, sautéing until the onion softens and becomes translucent. Sprinkle in the flour and stir constantly for 2–3 minutes. Slowly whisk in the chicken broth, allowing it to blend into a smooth, creamy sauce. Add the salt, pepper, Italian seasoning, half the cheddar, half the mozzarella, and the heavy cream. Keep stirring until the cheeses fully melt and the sauce thickens.

Step 4 – Combine and Bake

Now it all comes together. Add the drained tomatoes, cooked chicken, and spaghetti into the skillet with the sauce. Stir well until everything is coated evenly. Transfer this mixture into a 9×13-inch baking dish. Sprinkle the remaining cheddar and mozzarella on top. Bake uncovered at 375°F for 25 minutes until the cheese melts and the edges are bubbly.
