Preparing the Chicken:

Start by seasoning the chicken breasts with salt and pepper on both sides.

Heat a skillet over medium-high heat and add a tablespoon of oil.

Sear the chicken breasts for about 6-7 minutes per side until they're fully cooked.

Remove the chicken from the skillet and let it rest for a few minutes. Then, slice it into thin strips.

Cooking the Tortellini:

Bring a large pot of salted water to a boil.

Add the tortellini to the boiling water and cook according to the package instructions.

Once cooked, drain the tortellini and set it aside.

Preparing the Alfredo Sauce:

In the same skillet used to cook the chicken, melt the butter over medium heat.

Add the minced garlic and sauté for about a minute until fragrant.

Sprinkle the flour over the melted butter and garlic, stirring constantly for 2 minutes to create a roux.

Slowly pour in the heavy cream while continuously whisking to avoid lumps.

Cook the sauce for about 5 minutes until it thickens.

Stir in the grated Parmesan cheese until fully melted and combined.

Season with salt and pepper to taste.

Bringing It All Together:

Add the cooked tortellini and sliced chicken to the Alfredo sauce.

Gently toss everything together until the tortellini and chicken are evenly coated.

Simmer the mixture for a few minutes to allow the flavors to meld together.

Taste and adjust the seasoning if needed.
