Cooking what I want in 2019! Yes we’ve been on a roll with carbs and cauliflower here, but I wanted to make my ultimate fantasy pizza a reality while we’re still hibernating from the (apparently) never ending snow and cold. This vegan Buffalo cauliflower pizza is a bit of extra work, but it will BLOW. YOUR. MIND.

It’s so, so flavourful. Spicy from the Buffalo-style hot sauce, slightly sweet from the roasted onion cream, tangy from a good drizzle of vegan ranch dressing, and peppery/fresh from a finishing touch of arugula and herbs. I wanted to take this in a white-sauced pizza direction and knew that blending cooked onions into the base of a sauce would give me the velvety and creamy results that I wanted. A little touch of cashews helped with those goals too.

Our cauliflower is battered and baked in the standard way. and then we densely populate the entire surface of the pizza with that spicy, slightly crunchy goodness . Every bite has a ton of the spicy cauliflower. If you’re going to the trouble of battering and baking cauliflower before you even shape your pizza dough, you better make it count!

There is a detectable love of Buffalo-style hot sauce goods on this website. If you like this Vegan buffalo cauliflower pizza, you might also be interested in my Buffalo chickpea chili with mushrooms and cashew sour cream, Buffalo chickpea and cauliflower stuffed baked potatoes, or my 7-layer dip Buffalo retried beans.

If it’s still unapologetically winter where you are, this recipe is just the thing to cozy up to on a chill Saturday night in. The super hot oven will warm your house right up and the spicy heat does its own work too. Seeing the little radishes and peas popping up on the distinctly Californian Instagram accounts that I follow always gives me pangs of longing for local produce this time of year, but then I remember pizza and everything’s okay again :) Hope you’re having a great week!

Prep Time: 30 mins
Cook Time: 1 hr 5 mins
Total Time: 1 hr 35 mins
Servings 4



  • 1 small cooking onion, roughly chopped
  • 2 garlic cloves, peeled and cut in half
  • 1 tablespoon +1 teaspoon oil, divided
  • sea salt & ground black pepper, to taste
  • ¼ cup raw cashews, soaked for at least 1 hour and drained
  • 1 tablespoon nutritional yeast
  • 1 tablespoon lemon juice
  • ¼ cup filtered water


  • ¾ cup chickpea flour
  • ¾ cup filtered water
  • sea salt & ground black pepper, to taste
  • 4 cups SMALL cauliflower florets (the size of the tip of your pinky finger)
  • ½ cup Buffalo-style hot sauce or other hot sauce that you enjoy
  • 1 tablespoon oil


  • 1 lb pizza dough
  • 2 handfuls baby arugula
  • 2 green onions, finely sliced
  • vegan ranch dressing, for drizzling and dipping (see recipe notes)


  • Pizza Stone


  • Any hot sauce you like(/can handle) is great, but I prefer Tessemae’s hot Buffalo sauce here.
  • Use whatever pizza dough or base that you like. You could even do a cauliflower base for double cauliflower action! I think this sweet potato one would be great here.
  • You need to finish this pizza with ranch and that’s just the way it is! You can find my hemp seed ranch HERE, tahini ranch HERE, or pickled jalapeno ranch HERE (double spicy yessss).


  • Place an oven rack as low as possible in your oven and place a pizza stone on that rack. Place another oven rack near the top of the oven (second rung from the top). Turn the oven on to 450°F. Set up two baking sheets with parchment paper.
  • Make the roasted onion cream. On one baking sheet, combine the chopped onion, garlic cloves, 1 teaspoon of oil, salt, and pepper, Toss to combine and arrange in a single layer. Slide the baking sheet into the oven (top rack) and roast until onions are charring a bit on the edges, about 15 minutes. Remove onions and let cool slightly.
  • In an upright blender, combine the roasted onions and garlic, remaining tablespoon of oil, cashews, nutritional yeast, lemon juice, water, and some salt and pepper. Blend on high until totally smooth and creamy. Adjust seasoning if necessary. Scrape roasted onion cream into a small bowl and set aside.
  • While onions are roasting, you can also have the cauliflower cooking. In a large bowl, whisk together the chickpea flour, water, salt, and pepper until smooth. It should have the consistency of thin pancake batter. Drop the small cauliflower florets into the batter and stir until all pieces are lightly coated. Using a slotted spoon, carefully transfer battered cauliflower to the baking sheets, tapping off excess batter before setting on the baking sheet. Spread cauliflower out as much as you can and slide into the oven. Bake for 20 minutes, or until batter is dry and slightly browned. Remove cauliflower from the oven and let cool slightly
  • Rinse out the large bowl that you used to batter the cauliflower. Pour the hot sauce and tablespoon of oil into the bowl and whisk to combine.
  • Transfer the battered and baked cauliflower to the bowl with the hot sauce, breaking up the pieces if necessary. If there are baked bits of batter, break them off and discard them. Toss the battered cauliflower in the hot sauce mixture until it is evenly coated. Return the sauced cauliflower to the baking sheet. Bake the cauliflower for another 15 minutes or until edges are slightly browned and exterior is dry. Remove cauliflower once sufficiently cooked and let it cool slightly. Increase the oven temperature to 500 degrees F.
  • Dust your working surface and a pizza peel with flour OR line it with a piece of parchment paper. Start stretching/rolling out the dough until you have a 12-inch circle of even thickness. Carefully transfer the dough circle to the floured/papered peel. If you use the paper method, trim the paper so that you have a ½ inch border around the circle of dough.
  • Spread the roasted onion cream on the pizza evenly, leaving about ½ an inch at the crust area. Top the pizza with all of the Buffalo battered cauliflower. Lightly press the battered florets into the onion cream and dough.
  • Jiggle the pizza peel to ensure that the pizza will come loose. If it’s sticking, carefully lift up the edges and toss in a bit more flour until it seems to loosen from the peel. If you’re using parchment, ignore this step!
  • Open the oven and with equal measures of care and efficiency, slide the pizza off of the peel and onto the hot stone with a few flicks of your wrist (or just pull a tab of the parchment paper). Close the oven immediately.Let the pizza cook for 7 minutes. Open the oven and, using the peel, rotate the pizza. Cook for an additional 5 minutes, or until the top crust is browning in spots and the onion cream is drying out near the crust.
  • Remove the Buffalo cauliflower pizza from the oven. Cut it into slices and sprinkle the arugula and green onions on top. Drizzle with the vegan ranch as well. Enjoy immediately!
