Prep Time 12 mins
Cook Time 8 hrs 10 mins
Servings 4 -5 servings


  • for the cauliflower:
  • 1 medium-sized head of cauliflower
  • 3 tbsp. avocado oil
  • 2 tsp. kosher salt
  • for the tahini dressing:
  • 1/2 cup tahini
  • juice of 1/2 of a lemon
  • 1 tsp. garlic powder
  • 1 tbsp. maple syrup
  • 1 tsp. salt
  • 3/4 cup water + more if needed to thin out the dressing
  • for the spicy herb sauce:
  • 1 cup parsley
  • 1 cup cilantro
  • 2 garlic cloves
  • 2 jalapeƱos deseeded
  • splash of lemon juice
  • 3/4 tsp. cumin
  • 1/2 tsp. sumac
  • 1/2 tsp. pepper
  • 1/2 cup olive oil


  • Fill a large pot with about 2 inches of water and bring to a boil. Add the whole head of cauliflower and cover to steam for about 10-12 minutes. Preheat the oven to 475 degrees F.
  • Use tongs to lift the cauliflower out of the water and on to a baking sheet topped with a cooling rack. Placing the cauliflower on top of the rack allows for heat to circulate around the entire cauliflower.
  • Top with avocado oil, and salt and place in the oven to roast for approximately 50-55 minutes until the florets are golden brown.
  • While the cauliflower is roasting make the tahini sauce by whisking together all of the ingredients until a creamy, drippy sauce forms. Add 1 tbsp. of water at a time after the initial amount of water and whisk until the consistency is thin enough to drizzle.
  • Next, prepare the spicy green herb sauce by adding all of the ingredients to a food processor. Pulse until well combined and set aside.
  • Remove the cauliflower from the oven. Place on a dish or plate and drizzle with the tahini and then the spicy green sauce. Garnish with a dash of salt, fresh mint and sliced chili peppers if desired. Enjoy!
