Ingredients for Quick & Easy Chicken Spaghetti
One of the best things about this recipe is that it uses simple, everyday ingredients. Here’s everything you’ll need to make this delicious chicken spaghetti:
- 8 oz spaghetti – Regular or thin spaghetti works best
- 2 cups cooked chicken – Diced or shredded (rotisserie chicken works great!)
- 1 small onion – Finely diced
- 1 red bell pepper – Diced into small pieces
- 2 tablespoons olive oil – For sautéing the vegetables
- 2 cups shredded cheddar cheese – Sharp cheddar gives the best flavor
- 1 cup chicken broth – Low-sodium recommended
- 1 cup milk or cream – Whole milk or half-and-half works best
- 2 tablespoons all-purpose flour – To thicken the sauce
- 1 teaspoon seasoned salt – Adds perfect flavor
- ½ teaspoon chili powder – For a little kick (optional)
Step-by-Step Instructions
Follow these simple steps to create your delicious chicken spaghetti in just 30 minutes:
Cook the Pasta
Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente according to package directions (usually 7-8 minutes). Drain and set aside.
Sauté the Vegetables
While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the diced onion and bell pepper, cooking until softened, about 3-4 minutes.
Make the Sauce
Sprinkle flour over the vegetables and stir for 1 minute. Gradually whisk in the chicken broth and milk, stirring constantly to prevent lumps. Bring to a simmer and cook until the sauce begins to thicken, about 3-5 minutes.
Add Chicken and Cheese
Stir in the cooked chicken and 1½ cups of the shredded cheddar cheese. Season with seasoned salt and chili powder. Continue stirring until the cheese is fully melted and the sauce is smooth.
Combine with Pasta
Add the cooked spaghetti to the skillet and toss until the pasta is evenly coated with the sauce. If the mixture seems too thick, add a little more chicken broth to reach your desired consistency.
Final Touch
Transfer to a serving dish and sprinkle with the remaining ½ cup of cheddar cheese. If desired, place under the broiler for 2-3 minutes until the cheese is bubbly and golden.
Time-Saving Tips
Make this Quick & Easy Chicken Spaghetti Recipe even faster with these helpful shortcuts:
- Use rotisserie chicken – Skip cooking the chicken and use a store-bought rotisserie chicken instead. Simply shred or dice about 2 cups worth.
- Pre-shredded cheese – While freshly grated cheese melts better, pre-shredded cheese works fine in a pinch and saves prep time.
- Pre-chopped vegetables – Many grocery stores sell pre-chopped onions and bell peppers in the produce section.
- Cook pasta ahead – You can cook the spaghetti up to a day in advance and store it in the refrigerator until needed.

Pro Tip: Make a double batch and freeze half for another meal! This chicken spaghetti freezes beautifully for up to 3 months. Just thaw overnight in the refrigerator and reheat in the oven at 350°F until hot and bubbly.
Customization Options
This Quick & Easy Chicken Spaghetti Recipe is incredibly versatile. Here are some delicious ways to make it your own:
Vegetarian Version
Swap the chicken for 8 oz of sliced mushrooms and use vegetable broth instead of chicken broth. Sauté the mushrooms with the onions and peppers until golden brown.
Spicy Kick
Add a diced jalapeño with the bell peppers and onions, or stir in a few dashes of hot sauce or red pepper flakes to the sauce for extra heat.
Extra Veggies
Add diced zucchini, carrots, or frozen peas to boost the nutritional value. Just add firmer vegetables like carrots when you sauté the onions, and more delicate ones like peas at the end.
