In a large pot of boiling salted water, cook the tortellini according to package instructions. Once cooked, drain and set aside.
In a large skillet, heat olive oil over medium heat. Season the chicken breasts with salt and pepper. Add the chicken to the skillet and cook for 6-7 minutes on each side, or until cooked through and golden brown. Remove from the skillet and let rest for a few minutes before slicing into strips.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant. Add the halved cherry tomatoes and Italian seasoning, cooking until the tomatoes begin to soften, about 3-4 minutes.
Pour in the heavy cream and bring the mixture to a gentle simmer. Stir in the baby spinach and cook until wilted.
Add the grated Parmesan cheese to the sauce, stirring until melted and smooth. Then, gently fold in the cooked tortellini and sliced chicken. Toss until everything is well coated in the creamy sauce.
Remove from heat, adjust seasoning with salt and pepper if needed.
Notes
Serve with fresh basil and extra Parmesan cheese for garnish.
