  • Rich and creamy. The sauce is easy to make and so creamy, filled with savory garlic, ripe tomatoes, and zesty Italian seasoning. 
  • Extra cheesy. Kids and adults alike love this recipe, and I suspect it has something to do with the copious amounts of melty cheese! Of course, you can adapt the amount of cheese depending on how indulgent you’re feeling.

Ingredients for chicken spaghetti.

Ingredients You’ll Need

Here are some notes on the ingredients you’ll need to make a delicious baked chicken spaghetti. Don’t forget to scroll to the recipe card below the post for the full amounts and recipe details.

  • Spaghetti – Regular or whole wheat dry spaghetti. Another long pasta, like linguine or fettuccine, will also work.
  • Chicken – You’ll need cooked shredded chicken. Use leftover chicken breast or you can buy a rotisserie chicken from the store and shred it.
  • Butter
  • Onion and Garlic – Finely chopped yellow onion and freshly minced garlic. You can adapt the amount of garlic to taste.
  • Flour
  • Broth – I recommend low-sodium chicken broth, chicken stock, or vegetable stock.
  • Heavy Cream – You can also use milk or half-and-half.
  • Seasoning – Italian seasoning, plus salt and pepper to taste. 
  • Canned Tomatoes – Rotel tomatoes are a classic choice, but feel free to use any brand of diced tomatoes.
  • Cheese – Shredded cheddar cheese, or another melty variety. Grate the cheese fresh from the block so that it melts smoothly.

How to Make Chicken Spaghetti

With just 10 minutes of prep, you can have this chicken spaghetti in the oven and on the way to your dinner table.

  • Cook the pasta. Start by boiling and draining the spaghetti. Since you’ll be baking the pasta afterward, cook it a minute or two shorter than the suggested time on the package.
  • Sauté. Meanwhile, sauté onions and garlic in a skillet with butter. Stir in the flour and let it cook off to make a “roux”. This creates the base for the cream sauce.
  • Make the sauce. Pour in your chicken broth and heavy cream, and sprinkle in the Italian seasoning. Whisk everything together and then season with salt and pepper as the sauce thickens.
  • Combine. Next, stir in canned tomatoes, shredded chicken, and about half of the grated cheese. Lastly, mix in the cooked spaghetti.
  • Bake. Transfer the chicken pasta to a large casserole dish and sprinkle over the remaining shredded cheese. Bake the spaghetti at 350ºF for 25 minutes until it’s melty and bubbly. 
  • Serve! Take your chicken spaghetti out of the oven and dig in. See the section below for tasty serving ideas.

Tips and Variations

Here are some bonus tips, plus a couple of easy ways to adapt this chicken spaghetti recipe:

  • Don’t overcook the pasta. Make sure to time the pasta correctly. It should be slightly undercooked, so you’ll want to remove the spaghetti from the heat and drain it about one minute before it reaches the recommended cooking time.
  • Add more veggies. Plenty of fresh and frozen vegetables would taste amazing in this recipe! Add sautéed diced zucchini, red bell peppers, and broccoli, or try a frozen veggie medley with sweet corn, green beans, and diced carrots. Greens like kale, spinach, and peas are also good options.
  • More add-ins. Try a variation of Tuscan chicken pasta with mushrooms and diced San Marzano tomatoes. Or, add cooked crispy bacon, spicy Italian sausage, or chopped chorizo. You can also make a variation of lemon chicken with a squeeze of fresh lemon juice, lemon zest, and capers.

What to Serve With Chicken Spaghetti

This creamy chicken spaghetti goes well with a side of crunchy tossed salad or fresh tomato mozzarella salad and hot-from-the-oven garlic bread (or, make garlic bread in the air fryer!). We love pairing this pasta dish with snappy sautéed asparagus or tender roasted green beans to round out a family meal.

Can I Prepare This Chicken Pasta Ahead?

Yes! This recipe can be meal-prepped 1-2 days in advance. Prepare the chicken spaghetti as directed and transfer the pasta to the casserole dish. Instead of baking, allow the spaghetti to cool completely, then wrap it tightly to store in the fridge. When you’re ready to bake the following day, unwrap the pasta and bake as directed. Note that you may need to add an extra few minutes to the baking time if the casserole is cold from the fridge.

Storing and Reheating Leftovers

  • Fridge. Store any leftover chicken spaghetti in an airtight container in the fridge for 3-4 days. Reheat leftovers in the microwave in increments, or on the stovetop until heated through.
  • Freeze. Store the baked and cooled spaghetti airtight and keep it frozen for up to 2-3 months. Defrost in the fridge overnight before reheating.
