This pesto chicken tortellini recipe is a simple yet elegant one pan meal! It pairs cheesy pasta with a creamy basil sauce and silky mozzarella stirred into every bite.
Add the butter to a skillet over medium heat. Once it melts, add the garlic and sauté for about a minute, stirring constantly.
Stir in the Italian seasoning, crushed red pepper flakes, pesto, chicken broth, and cream until smooth, then mix in the tortellini. Increase the heat to medium-high, and once it starts to bubble, cook, uncovered, stirring occasionally, for 5 minutes. Cooking the tortellini in the sauce helps thicken it by releasing starch. Reduce the heat if it starts to boil like crazy.
Stir in the chicken and cook it for another minute or two until it's warmed through and the sauce has thickened to your liking. Add a splash more cream if the sauce reduces too much.
Take the pan off the heat and add in the mozzarella. Stir/toss until melted. Season with salt & pepper as needed and serve immediately.
