Cheesy Broccoli Cauliflower Soup

Rich, creamy and slightly decadent, this cheesy broccoli cauliflower soup is nonetheless absolutely delicious and sure to impress your family and friends. If you like broccoli or cauliflower, then you’ll need no convincing here. But if not everyone shares your love of cruciferous vegetables, this is the soup to bring them on board. Serve this to those who say, “I don’t like broccoli,” or “Cauliflower is gross,” and get ready for a change of attitude!

You can use fresh or frozen broccoli and cauliflower with equally excellent results. Don’t worry about chopping the vegetables too fine if you plan to blend them later as this recipe suggests. The salmon seasoning might seem like an odd thing to include in a non-seafood soup, but it goes very well with cauliflower and rich, cheesy dishes. If you don’t have any on hand, feel free to substitute an equal amount of Old Bay, Cajun or creole seasoning. The lemon juice, added right at the end, helps temper the richness of the cheese and gives the finished dish a nice bit of brightness.
