Preheat oven to 425º F, and line a large baking tray with parchment paper.
To the baking tray, add cauliflower. Drizzle the cauliflower with olive oil, and then season it with sea salt, thyme, and black pepper.
Roast the cauliflower for about 25 minutes, until the cauliflower is very soft and has begin to brown. To get a thick and creamy hummus, the cauliflower needs to be cooked well to reduce the moisture content.
Allow the cauliflower 10-15 minutes to cool, and then add it to a food processor bowl, along with tahini, lemon juice, olive oil, garlic, salt and pepper.
Process the cauliflower hummus for 3-4 minutes. If necessary, stop and scrape down the sides. It will continue to thicken and create a smooth, silky texture the longer you process, so don’t be shy about keeping the food processor running a bit here!
Chill the hummus prior to serving (it’s delicious cold out of the fridge!). Garnish with an extra drizzle of olive oil, some paprika (or smoked paprika), and optionally some chopped parsley. Some pine nuts or toasted almonds make a great texture on this as well!
