One Pot Chicken Spaghetti Recipe: Creamy Tomato Noodles in One Pan

This one-pan wonder combines tender chicken, creamy tomato sauce, and perfectly cooked spaghetti without the mess of multiple dishes. It’s the ultimate weeknight solution when you need comfort food fast.

The secret lies in cooking everything together, allowing the pasta to absorb the rich tomato-chicken flavors as it cooks. No pre-cooking the chicken or boiling noodles separately—just layer the ingredients and let the pot do the work.

You’ll end up with a hearty, satisfying meal where every bite delivers juicy chicken, al dente pasta, and a velvety sauce that clings to each strand. It’s the kind of dish that tastes like it took hours but comes together in under 30 minutes.

Cleanup is just as simple as the cooking process. This is comfort food at its most efficient.

Ingredients for One Pot Chicken Spaghetti

Nothing fancy here. Just chicken, pasta, and a rich tomato sauce all in one pot.

The chicken is the star. Boneless skinless breasts stay tender and cook fast. Grab them from any supermarket—Costco if you’re feeding a crowd. The spaghetti should be standard #8 thickness (the thin kind can turn mushy). Barilla or De Cecco hold up best in one-pot recipes. For the tomatoes, San Marzano if you’re feeling fancy, but any diced works.

No heavy cream? Half-and-half or whole milk in a pinch (just know the sauce won’t be as luscious). Swap fresh garlic for 1 tsp garlic powder if you’re out. The Italian seasoning can be equal parts oregano and basil. Chicken broth substitute? Water plus bouillon cube—not ideal, but it’ll do. No Parmesan? Skip it or use pecorino for a sharper bite.

Leftovers keep 3-4 days in the fridge—reheats beautifully. Freeze without the pasta (it turns to mush), just the chicken and sauce for up to 3 months. Pro tip: add a splash of broth when reheating to loosen the sauce back up.

Step-by-Step Instructions for One Pot Chicken Spaghetti

This method keeps everything in one pan while building layers of flavor you’ll love.

Step 1: Sauté Chicken and Aromatics

Heat the 2 tbsp olive oil in a large pot or deep skillet over medium-high heat. Add the 1.5 lb boneless skinless chicken breasts cut into bite-sized pieces and cook for 5-6 minutes, stirring occasionally, until the chicken is no longer pink on the outside.

Push the chicken to one side and add the 1 whole onion finely diced. Cook for 3 minutes until it starts to soften. Then add the 3 cloves garlic cloves minced and cook for 30 seconds until fragrant. This builds the flavor foundation that makes this dish so satisfying.

Step 2: Build the Sauce Base

Stir in the 2 tbsp tomato paste and cook for 1 minute to deepen its flavor. Then add the 1 can canned diced tomatoes (with juice), 2.5 cups chicken broth, 1 tsp dried Italian seasoning, 1 tsp salt, and 0.5 tsp black pepper.

Bring the mixture to a gentle boil, then reduce heat to medium. Let it simmer for 5 minutes to allow the flavors to meld together. The liquid should be bubbling gently at the edges—this is where the magic starts to happen.

Step 3: Add Pasta and Finish Cooking

Stir in the 8 oz spaghetti broken in half, making sure it’s fully submerged in the liquid. Cover and cook for 10 minutes, stirring occasionally, until the pasta is nearly tender. The pasta will absorb much of the liquid as it cooks, creating that perfect texture.

Uncover and stir in the 0.5 cup heavy cream. Cook for an additional 2-3 minutes until the pasta is al dente and the sauce has thickened slightly. The cream adds that luxurious, velvety finish that makes this dish so special.

Step 4: Garnish and Serve

Remove from heat and let it sit for 2 minutes to allow the sauce to set slightly. The pasta should be coated in a rich, creamy tomato sauce with tender chicken pieces throughout.

Sprinkle with the 0.5 cup Parmesan cheese and the 0.25 cup fresh parsley chopped. Serve immediately while hot, with extra Parmesan on the side if desired. The parsley adds a pop of color and freshness that balances the richness of the dish perfectly.

Essential Equipment for This Recipe

Essential Pot

You need a large, heavy-bottomed pot or deep skillet with a tight-fitting lid. I recommend a 5-6 quart Dutch oven—my Le Creuset works perfectly. A wide base ensures even heat distribution for cooking the chicken and pasta uniformly. 🔥

Wooden Spoon

A sturdy wooden spoon is ideal for stirring without scratching your pot. It helps break up the chicken and prevents pasta from sticking to the bottom. Avoid metal utensils that can damage non-stick surfaces.

Chef’s Knife

Use a sharp 8-inch chef’s knife for dicing the onion and mincing the garlic efficiently. I prefer Wüsthof for its balance and durability. A dull knife makes prep slower and more dangerous.

Cutting Board

A large plastic or wood cutting board gives you space to prep all your ingredients at once. I like OXO’s utility board with a juice groove. This keeps your workspace organized and cleanup simple.

Measuring Tools

Accurate measurements matter for the sauce balance. Use a 1-cup liquid measure for the broth and cream, and measuring spoons for the spices. A kitchen scale helps for precise pasta portions.

Tongs

For turning the chicken pieces, 12-inch tongs give you control without crowding the pot. I recommend OXO’s locking tongs—they’re heat-resistant and easy to store. They also help test pasta doneness. 💡
