This creamy cauliflower sauce is a like a healthy alfredo sauce using cauliflower as a base. It has less calories and all the benefits of this healthy veggie!
Heat the butter in a large pot over medium heat. Add the cauliflower and saute for 4 minutes until lightly browned. Add the garlic and cook for 1 to 2 minutes until fragrant. Add the vegetable broth, garlic powder, oregano, and 1/2 teaspoon kosher salt. Bring to a simmer, then cover and cook 6 to 7 minutes on medium high heat until the cauliflower is tender when pierced with a fork.
Carefully transfer the contents to a blender and blend on high until a smooth sauce forms. Add the Parmesan cheese and additional 1/2 teaspoon salt, and blend again. Taste: if you’d like more cheese you can add a little more, but we like adding a little extra Parmesan to the pasta when we stir in the sauce. Serve immediately with 1 pound pasta. (You can also refrigerate for up to 1 week: warm on the stovetop before serving.)
