How to Make One Pot Chicken Parmesan Pasta

If you love the comfort of pasta night but want something faster and bolder than a plain spaghetti, this One Pot Chicken Parmesan Pasta is the answer. It’s everything you adore about chicken parmesan—juicy seasoned chicken, tangy marinara, gooey mozzarella, and a sprinkle of savory Parmesan—combined into one skillet-friendly meal. The result is a creamy, saucy, crowd-pleasing dinner that comes together with minimal cleanup and maximum flavor.

This recipe uses three chicken breasts cut into bite-sized pieces, a pantry-friendly jar of Ragu Old World Traditional Pasta Sauce, and simple seasonings you probably already have on hand. Using rigatoni gives you ridged tubes that trap sauce in every bite, and finishing with fresh parsley lifts the whole dish with a brightness that balances the cheese and tomato.

Why this one-pot method works

Cooking everything in one pot saves time, reduces dishes, and lets the pasta absorb flavors directly from the sauce and chicken as it simmers. The chicken pieces cook quickly, then finish in the sauce so they stay tender and soak up that rich tomato taste. The shredded mozzarella melts into creamy pockets throughout the pasta, while Parmesan adds a salty, nutty finish.

Ingredients

• 3 chicken breasts (diced into bite sized pieces)
• 2 tsp Italian seasoning
• ½ tsp garlic powder
• 1/2 tsp onion powder
• 1 tsp garlic salt
• 1 medium yellow onion (finely minced)
• 1 tbsp garlic paste
• 16 ounces dried rigatoni pasta
• 1 24 ounce jar Ragu Old World Traditional Pasta Sauce
• 24 ounces chicken stock
• 1 1/2 cup mozzarella cheese (shredded)
• ½ cup Parmesan cheese (shredded)
• Salt & pepper (to taste)
• 2 tbsp fresh parsley (finely chopped)

Equipment

• Large deep skillet or wide heavy pot with lid
• Wooden spoon or heatproof spatula
• Measuring spoons and cups
• Sharp knife and cutting board
• Grater (if shredding your own cheeses)

Prep ahead

Dice the chicken into even bite-sized pieces so they cook uniformly. Finely mince the yellow onion and chop the parsley. If you prefer freshly shredded cheese, grate the mozzarella and Parmesan now. Having everything measured and ready will make the cooking flow quickly.

Step-by-step directions

1. Season the chicken: Place the diced chicken breasts in a bowl and sprinkle with 2 tsp Italian seasoning, ½ tsp garlic powder, 1/2 tsp onion powder, and 1 tsp garlic salt. Toss the pieces until they are evenly coated. This blend builds the classic chicken parmesan flavors right into the meat before it hits the pan.
2. Sauté the aromatics and brown the chicken: Heat a large deep skillet or wide pot over medium heat. If your pan is nonstick, you may not need additional oil; otherwise add a tablespoon of neutral oil. Add the finely minced medium yellow onion and 1 tbsp garlic paste to the hot pan. Cook, stirring frequently, until the onion is soft and translucent, about 3 to 4 minutes. Push the onion mixture to the side, then add the seasoned diced chicken in a single layer. Cook the chicken pieces, stirring occasionally, until they are browned on the outside and nearly cooked through, about 4 to 6 minutes.
3. Add the pasta and liquids: Pour the entire 1 24-ounce jar of Ragu Old World Traditional Pasta Sauce into the skillet with the chicken and aromatics. Add 24 ounces of chicken stock and stir to combine. Scrape any browned bits from the bottom of the pan; those add great flavor. Add the 16 ounces of dried rigatoni pasta, making sure the pasta is submerged and evenly distributed in the sauce and stock mixture.
4. Simmer until pasta is al dente: Bring the mixture to a gentle boil over medium-high heat, then reduce the heat to a simmer. Cover the skillet with a lid and cook, stirring every 4 to 5 minutes to prevent sticking, until the rigatoni is tender but still has a slight bite—about 12 to 15 minutes. If the sauce thickens too much before the pasta is cooked, add a splash more chicken stock or water to loosen it.
5. Adjust seasoning: Taste the sauce and pasta, then season with salt and pepper to taste. Remember the Parmesan will add saltiness, so season conservatively at first.
6. Stir in the cheeses: Once the pasta is al dente and the sauce has thickened to your liking, remove the skillet from heat. Sprinkle 1 1/2 cups shredded mozzarella cheese and ½ cup shredded Parmesan cheese evenly over the top. Replace the lid for 2 minutes to let the cheeses melt, or stir gently until the mozzarella becomes stringy and the Parmesan is fully incorporated into the sauce. This creates a creamy, cheesy finish that clings to the pasta and chicken.
7. Garnish and serve: Finish with 2 tbsp finely chopped fresh parsley for a bright herbal note. Give the pasta one last gentle stir to distribute the parsley and melted cheese. Serve immediately, spooned into bowls or onto plates while everything is hot and melty.

Troubleshooting tips

• If the sauce reduces too quickly and the pasta isn’t yet tender, add a few tablespoons of chicken stock or hot water and continue simmering until the pasta is done.
• To prevent the pasta from sticking, stir frequently especially during the first 10 minutes of cooking. Use a wide pot so the pasta has room to move.
• If you prefer an even saucier dish, stir in an extra 1/4 cup of chicken stock or 2 tablespoons of olive oil after the cheeses melt.
• For more crust and browned cheese, transfer the skillet briefly under a broiler for 1 to 2 minutes—watch closely to avoid burning.

Variations and swaps

• Vegetable boost: Stir in a couple of handfuls of fresh baby spinach during the last 2 minutes of cooking so it wilts into the sauce. Sliced mushrooms or diced bell pepper added when sautéing the onion also work well.
• Different pasta shapes: If you don’t have rigatoni, use penne, ziti, or another tubular pasta. Cook times may vary slightly.
• Extra heat: Add 1/4 to 1/2 tsp crushed red pepper flakes when you add the jarred sauce for a spicy kick.
• Cheese variations: Swap half the mozzarella for provolone or fontina for a different melty profile, but keep the total cheese amounts the same.

Make-ahead and storage

This dish reheats beautifully. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over low heat with a splash of chicken stock to loosen the sauce, or microwave in short bursts until warmed through. If you plan to freeze, cool completely and store in freezer-safe containers for up to 2 months; thaw overnight in the refrigerator before reheating.

Serving suggestions

Serve this One Pot Chicken Parmesan Pasta with a simple green salad dressed in lemon and olive oil to cut through the richness. Crusty bread or garlic bread makes an excellent side for soaking up extra sauce. A squeeze of lemon over the finished dish can add a welcome brightness if the tomato and cheese feel heavy.

Nutrition and portioning

This recipe makes about 4 to 6 servings depending on appetite and side dishes. It provides a balanced combination of protein from the chicken, carbs from the rigatoni, and calcium from the cheeses. If you need to stretch the meal, add an extra cup of baby spinach or a side of roasted vegetables to bulk up the plate without much extra effort.

Final notes

One Pot Chicken Parmesan Pasta is a weeknight lifesaver: simple, satisfying, and full of familiar flavors. The secret is in efficiently layering flavors—season the chicken well, build aromatics with onion and garlic, and let the pasta slowly absorb the tomato and stock. With a quick sprinkle of fresh parsley and generous melting cheese, you’ll have a comforting dinner that looks and tastes like you spent much longer in the kitchen than you actually did.

Now gather your ingredients and put a skillet to work—this family-friendly, cheesy dinner is waiting.
