In a large skillet, heat the olive oil over medium heat. Season the chicken pieces with salt and pepper. Once the oil is hot, add the chicken to the skillet. Cook for about 5-7 minutes, or until the chicken is golden and cooked through, stirring occasionally.
Once the chicken is cooked, add the butter and minced garlic to the pan. Stir continuously for about 1 minute, or until the garlic is fragrant but not browned.
Pour in the low-sodium chicken broth and water, scraping any browned bits off the bottom of the pan. This will add incredible flavor to your sauce!
Stir in the refrigerated cheese tortellini. Bring the mixture to a gentle boil, then reduce the heat to a simmer. Cook the tortellini according to the package instructions, usually around 3-5 minutes.
Once the tortellini is cooked, reduce the heat to low. Add the Neufchâtel cheese pieces and freshly grated parmesan cheese. Stir gently until the cheeses are melted and the sauce is creamy.
Stir in the fresh lemon juice and baby spinach leaves. Cook for an additional minute, just until the spinach wilts. Taste and adjust seasoning if necessary.
Serve your One Pan Creamy Lemon Chicken Tortellini warm, garnished with additional parmesan if desired. Enjoy the creamy, tangy flavors in every bite!
