Bring a large pot of salted water to a boil. Add the cauliflower florets and garlic cloves, and boil until the cauliflower is knife tender, about 10 minutes.
1 head of cauliflower, 5 to 6 garlic cloves
Drain the cauliflower, reserving about ¼ cup of the water for later use. Transfer the cauliflower and garlic to a food processor. Add the Parmesan cheese, butter, salt, and pepper.
⅓ cup Parmesan cheese, ¼ cup unsalted butter, Salt and pepper
Pulse until the cauliflower reaches the desired consistency. Use some of the boiling water if needed to thin out the cauliflower mash. Taste, and adjust salt and pepper if needed.
Serve hot with your favorite entree.
