Preparation Steps

• Place the fresh spinach leaves in a large colander set in the sink.
• Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package directions. Once cooked, drain the pasta over the spinach in the colander to wilt the spinach. Set aside.
• In a large skillet, heat 1 tablespoon of the reserved oil from the sun-dried tomatoes over medium heat. Add the chopped onion and sun-dried tomatoes; cook until softened, about 3 minutes. Stir in the minced garlic, crushed red pepper flakes, salt, and pepper; cook for another minute.
• Increase the heat to medium-high and add the broth to the skillet. Cook until the liquid is reduced by half, about 2 minutes. Stir in the sour cream, Parmesan cheese, and butter until well combined and creamy.
• Add the cooked spaghetti and wilted spinach to the skillet. Toss everything together until the pasta is evenly coated with the sauce.
