Since the heat here is all provided via Sriracha Sauce, this recipe, in terms of spiciness, is super simple to adjust. You could opt not to place the Sriracha on the onion and cauliflower and just roll with the hot sauce as a garnish. Or simply use less while baking and put none atop. On the flip side, double up on the Sriracha for that extra kick, or add a half teaspoon of cayenne pepper powder for even more heat. Whatever your preference, there’s a way to make this work.

Because it’s a well-blended smoother soup, you can make it a few days in advance and still enjoy its delicious flavors. Sriracha and cauliflower cheese soup is an excellent solution for a few workday lunches when prepped on a Sunday. Just store the soup in an airtight container and refrigerate it. It’ll be good for up to three days. Note: This soup doesn’t freeze well, so enjoy it fresh or within the first three days for the best flavor.
