When you are craving a rich, silky bowl of chicken Alfredo but don’t want to wash multiple pots and pans, this One Pot Chicken Alfredo is the ultimate weeknight winner! Everything from searing the marinated chicken to making the velvety sauce and cooking the pasta happens in a single pot.

The pasta cooks directly in a rich mixture of chicken stock, whole milk, cream, and shredded cheddar cheese. As the pasta releases its starches while simmering, it naturally thickens the sauce into the creamiest, glossiest Alfredo you’ll ever taste. Served with warm garlic bread, extra Parmesan, and a sprinkle of chilli flakes, it is pure comfort food made simple!

Ingredients

For the Chicken

• 2 chicken breasts (~500g)
• 1 tsp lemon juice
• 1 tsp salt
• 1 tsp black pepper
• 1 tsp paprika
• 1 tsp garlic powder
• 1 tsp soy sauce
• 2 tbsp vegetable oil, for cooking

For the Alfredo Pasta

• 3 tbsp butter
• 2 tbsp all-purpose flour
• 500ml chicken stock
• 500ml whole milk
• 250ml heavy cream
• 2 tsp paprika
• 2 tsp black pepper
• 1 tsp MSG (optional, for extra umami depth)
• 2 tsp dried oregano
• 1 cup shredded cheddar cheese
• 400g tripoline pasta (or broken lasagna sheets)

To Serve

• Garlic bread
• Grated Parmesan cheese
• Chilli flakes

Instructions

1. Marinate and Cook the Chicken

In a bowl, season the chicken breasts with lemon juice, salt, black pepper, paprika, garlic powder, and soy sauce. Mix well and let marinate for at least 10 to 15 minutes.

Heat 2 tablespoons of oil in a large pot or wide Dutch oven over medium-high heat. Add the marinated chicken breasts and sear for 3 to 4 minutes per side until golden brown, but only about 75% cooked through.

Remove the chicken from the pot onto a cutting board and set aside. Once cooled slightly, slice the chicken breasts into bite-sized cubes.

2. Make the Roux & Sauce Base

In the same pot (do not wipe it clean, as all those caramelized brown bits add huge flavor!), melt 3 tablespoons of butter over medium heat.

Add 2 tablespoons of flour and stir continuously for 1 minute to cook out the raw flour taste. Gradually pour in the chicken stock, whole milk, and heavy cream while whisking constantly to prevent any lumps.

Season the sauce with paprika, black pepper, MSG (if using), and dried oregano. Bring the liquid to a gentle simmer.

3. Cook the Pasta & Chicken

Add the 400g of uncooked tripoline pasta (or broken lasagna sheets) directly into the simmering sauce, pressing them down so they are submerged.

Stir in the cubed chicken pieces (and any rested juices from the cutting board!). Lower the heat to medium-low, cover the pot loosely, and let everything simmer together for 10 to 12 minutes, stirring every few minutes so the pasta doesn’t stick to the bottom of the pot.

(As the pasta cooks, it will absorb the liquids and release its starches, creating a thick, glossy sauce, while the chicken cooks through the remaining 25% to stay juicy!)

4. Cheese & Finish

Once the pasta is tender and cooked through (al dente), stir in 1 cup of shredded cheddar cheese until completely melted and velvety smooth. Remove from heat.

5. Serve

Garnish generously with freshly grated Parmesan and a pinch of chilli flakes. Serve hot alongside warm, buttery garlic bread for dipping!

The 75% Chicken Trick for Maximum Juiciness

A common issue with chicken pasta recipes is dry, rubbery meat from overcooking. My favorite trick is to sear the marinated chicken cutlets until they are 75% done, remove them, and slice them into cubes. Slicing and returning them to the pot while the pasta cooks allows the chicken to finish its last 25% of cooking directly inside the hot, simmering Alfredo sauce! This seals in the juices and infuses the chicken with rich creaminess.

Why Broken Lasagna Sheets or Tripoline Pasta?

Using tripoline pasta or breaking dried lasagna sheets into rustic chunks gives this dish such a fun, elevated feel! The wavy, ruffle edges trap the rich cheddar Alfredo sauce, garlic, and herbs in every single fold, ensuring you get maximum flavor with every forkful.

Tips for Getting It Right

• Stir Frequently While Simmering: Because the pasta cooks directly in milk and cream, make sure to stir every 2 to 3 minutes during the cook time so the pasta doesn’t settle or stick to the bottom of the pot.
• Keep Hot Milk or Stock Nearby: If your pasta absorbs liquid faster than expected before it turns fully al dente, simply stir in a small extra splash of warm milk or stock to loosen the sauce.
• Use Low Heat for Cheese: Stir in your cheddar cheese right at the end after turning off the burner so it melts smoothly into a silky texture without breaking or separating.

Storage and Reheating

• Storage: Store leftover One Pot Chicken Alfredo in an airtight container in the refrigerator for up to 3 days.
• Reheating: One-pot pastas continue to absorb sauce as they cool in the fridge. Reheat in a pan over medium-low heat with a splash of milk or chicken stock to restore its original creamy consistency, or microwave for 1 to 2 minutes.

Frequently Asked Questions (FAQ)

Q. Can I use other pasta shapes like penne or fettuccine?

Yes! Penne, rigatoni, fettuccine, or farfalle (bow ties) all work great. Keep an eye on package cooking times, as thicker pasta shapes may require a few extra minutes of simmering and a small splash of additional milk.

Q. Can I use chicken thighs instead of breasts?

Absolutely! Boneless, skinless chicken thighs stay even juicier. Follow the exact same marination and 75% searing process.

Q. Do I need to pre-boil the pasta?

No! The entire beauty of this recipe is that the dry, uncooked pasta cooks directly inside the spiced milk, stock, and cream mixture.
