Tender chicken, spinach, and mushrooms are tossed with chewy rotini in a rich, creamy sauce. This easy chicken spinach mushroom pasta is ready in just 30 minutes. Every bite is creamy, savory, and packed with tender vegetables.
Pat the chicken thighs dry with paper towels, then slice them against the grain into ¼-inch-thick pieces. Transfer to a large mixing bowl and season with ½ teaspoon salt, ½ teaspoon garlic powder, and ¼ teaspoon black pepper. Set aside.
Bring a large pot of water to a boil over medium-high heat and season with 2 teaspoons of salt. Boil the rotini for 1 minute less than the package directions until al dente. Reserve ¼ cup of the starchy pasta water, then drain the pasta and set aside.
Heat olive oil in a large pan over medium heat. Add the chicken in a single layer and cook until browned on the edges and the chicken reaches an internal temperature of 165°F. Set aside.
Melt the butter in the same pan. Add the mushrooms in a even layer and cook, stirring occasionally, until they release their moisture and become softened and golden. Sauté the garlic for 10 seconds.
Pour in the heavy cream and reserved pasta water. Gently simmer until the sauce slightly thickens and coats the back of a spoon.
Stir the baby spinach into the sauce until just wilted.
Remove the pan from the heat. Add the rotini and cooked chicken, then toss until everything is evenly coated in the creamy sauce.
