Place a large pot over high heat and fill with 2 inches of water or broth.
Place a steamer basket over the pan and add in the prepared Brussels sprouts.
Cover and steam until fork-tender but still bright green, about 4-5 minutes.
As soon as your sprouts are ready and tender-crisp, carefully transfer to a large bowl then add the clarified butter, garlic, parmesan cheese and parsley and toss to melt the butter and coat. Season with sea salt and pepper to taste.
