Ingredients You Need

Pasta & Chicken

• 12 oz dry spaghetti
  • Use regular, thin, or whole-wheat spaghetti.
  • You can swap with fettuccine or linguine if that’s what you have.
• 2–3 cups cooked chicken, shredded or diced
  • Rotisserie chicken works perfectly and saves time.
  • Leftover grilled or baked chicken adds great flavor.

Creamy Sauce Base

• 2 tbsp unsalted butter
• 1–2 tbsp olive oil
  • Use extra-virgin if you like a stronger flavor, or regular for milder taste.
• 4 cloves garlic, minced
  • Use jarred minced garlic as a shortcut, about 1½–2 tsp.
• 2 tbsp all-purpose flour
  • This thickens the sauce; use gluten-free flour if needed.
• 2 cups low-sodium chicken broth
  • Boxed broth works well; Better Than Bouillon gives deeper flavor.
• 1½ cups heavy cream
  • Swap with half-and-half for a lighter sauce, but it thickens a bit less.
• 1 cup freshly grated Parmesan cheese
  • Use a block and grate it; pre-shredded often clumps and melts poorly.
• ½ cup grated Romano or more Parmesan (optional, for extra punch)

Seasonings

• 1 tsp kosher salt, plus more to taste
• ½ tsp black pepper
• ½–1 tsp Italian seasoning
• ¼ tsp crushed red pepper flakes (optional, for mild heat)
• ¼ tsp onion powder (optional, for extra savory flavor)

Fresh Finish

• ¼ cup chopped fresh parsley or basil
• Extra Parmesan for serving

Equipment List

• Large pot for boiling spaghetti
• Large deep skillet or wide pot for sauce (12-inch works well)
• Tongs or pasta fork
• Measuring cups and spoons
• Whisk
• Cutting board and knife
• Cheese grater

Quick Tips & substitutions

• Salt the pasta water generously so the spaghetti carries flavor into the sauce.
• Cook spaghetti just to al dente; it finishes in the sauce and soaks up flavor.
• Use rotisserie chicken when you feel short on time or energy.
• Stir the sauce constantly after you add flour so it stays smooth and lump-free.
• Keep the heat on medium or medium-low after adding cream so it does not scorch.
• Add Parmesan off the heat or on low so it melts smoothly and does not turn grainy.
• Thin the sauce with extra broth or pasta water if it thickens too much.
• Use gluten-free spaghetti and gluten-free flour for a gluten-free version.
• Swap heavy cream with evaporated milk for a lighter but still creamy sauce.
• Add a handful of frozen peas or spinach at the end for easy veggies.

How to Make Creamy Spaghetti Chicken Recipe

Step 1: Cook the Spaghetti

1. Bring a large pot of water to a boil and add a big pinch of salt.
2. Add the spaghetti and cook until al dente, usually 1–2 minutes less than package directions.
3. Scoop out 1 cup of starchy pasta water and set it aside, then drain the spaghetti.
4. Toss the drained pasta with a drizzle of olive oil so it does not stick while you make the sauce.

Step 2: Sauté Garlic and Build the Roux

1. Heat a large deep skillet over medium heat and add butter and olive oil.
2. When the butter melts and foams slightly, add the minced garlic.
3. Stir and cook the garlic for about 30–60 seconds until it smells fragrant and looks lightly golden, not brown.
4. Sprinkle the flour over the garlic and fat, then whisk or stir until it forms a smooth paste.

Step 3: Add Broth and Cream

1. Slowly pour in the chicken broth while you whisk so the mixture stays smooth.
2. Stir until the mixture thickens slightly and looks glossy, about 2–3 minutes.
3. Pour in the heavy cream and keep stirring while the sauce heats and thickens again.
4. Keep the heat at medium or medium-low so the cream simmers gently, not rapidly.

Step 4: Season and Add Cheese

1. Add salt, black pepper, Italian seasoning, onion powder, and red pepper flakes if you use them.
2. Taste the sauce and adjust the salt level before you add cheese.
3. Lower the heat to low and add the grated Parmesan (and Romano if using) in small handfuls.
4. Stir after each handful until the cheese melts and the sauce turns silky and thick.

Step 5: Add Chicken and Spaghetti

1. Add the cooked chicken to the sauce and stir so the pieces warm through.
2. Toss in the cooked spaghetti and use tongs to coat every strand with the creamy sauce.
3. If the sauce looks too thick, splash in a bit of reserved pasta water or extra broth until it reaches your favorite consistency.
4. Taste again and adjust salt, pepper, or red pepper flakes.

Step 6: Finish and Serve

1. Turn off the heat and sprinkle chopped parsley or basil over the pasta.
2. Toss gently so the herbs spread through the dish.
3. Serve the Creamy Spaghetti Chicken Recipe hot with extra Parmesan on top.
4. Add a side salad or steamed veggies and call dinner done.

Recipe Variations

• Gluten-free: Use gluten-free spaghetti and a 1:1 gluten-free flour blend for the roux.
• Lighter version: Use half-and-half or a mix of milk and a little cream, and reduce cheese slightly.
• Low carb: Swap spaghetti with zucchini noodles or spaghetti squash and thicken the sauce with extra cheese instead of flour.
• Veggie boost: Stir in steamed broccoli, peas, spinach, or mushrooms during the last few minutes.
• Extra protein: Add crispy bacon bits or turkey bacon on top right before serving.
• Spicy twist: Increase red pepper flakes and add a pinch of smoked paprika.

Ways to Serve Creamy Spaghetti Chicken Recipe

• Pair with a simple green salad with lemony dressing.
• Serve with garlic bread or toasted baguette slices.
• Add roasted broccoli, green beans, or asparagus on the side.
• Pack leftovers in a thermos for a cozy work or school lunch.
• Top with extra herbs and a squeeze of lemon for brightness.

Storage Success

Store leftover Creamy Spaghetti Chicken Recipe in an airtight container in the fridge for up to 3–4 days. Add a splash of milk, cream, or broth when you reheat it so the sauce turns silky again. Reheat on the stove over low heat or in the microwave in short bursts, and stir often so it heats evenly. Skip freezing if possible, since cream sauces can turn grainy, but if you do freeze it, thaw gently and stir in a bit of fresh cream to revive the texture.
