Bring a large pot of water to a boil. (Note that you will need to save 1 cup of pasta cooking liquid to add back into dish). Cook pasta according to the package instructions.
While the pot of water is heating, heat 1 tbsp olive oil in a large skillet over medium heat. Add chopped mushrooms and cook for 10 minutes, stirring often until they are golden brown. Add minced garlic, chopped kale, salt, and a few cracks of pepper. Combine and saute for about 3 minutes until kale is wilted.
Once pasta is cooked, set aside 1 cup of cooking liquid, then drain. Place drained pasta back into large pot and add mushroom and kale mixture. Add the parmesan and water, quickly stirring with a wooden spoon until sauce is well combined and creamy. Serve immediately and enjoy!
