There are nights when you want something bold, satisfying, and a little bit fun to eat. This Buffalo Cauliflower Pizza fits the bill: spicy, crunchy cauliflower tossed in hot sauce piled on a creamy roasted onion base, finished with peppery arugula and bright green onions. It’s a crowd-pleaser that doesn’t rely on dairy—vegan-friendly if you choose a dairy-free ranch—and the textures keep every bite interesting.

The key to success here is timing and staging. Roasting the onion and blending it into a silky cream gives you a flavorful foundation that tames the heat of the Buffalo sauce. Meanwhile, the chickpea-flour batter crisps up the cauliflower without deep frying. With a hot stone and a quick final bake, the crust gets that blistered, slightly charred edge we all crave.

This post walks you through the exact workflow I use in a busy home kitchen—what to prep first, how to space the oven tasks so everything finishes together, and small tips that keep the pizza from sticking or getting soggy. No fluff—just clear steps to a fun, spicy pizza night.

What We’re Using

Ingredients

1 small cooking onion, roughly chopped — the base flavor for the roasted onion cream; roughly chopped so it roasts evenly.
2 garlic cloves, peeled and cut in half — adds aromatic depth to the cream; halved so they blend smoothly.
1 tablespoon + 1 teaspoon oil, divided — used to roast the onions and to mix with the hot sauce for tossing cauliflower.
Sea salt & ground black pepper, to taste — essential seasoning for both cream and cauliflower; adjust to preference.
1/4 cup raw cashews, soaked for at least 1 hour and drained — creates the creamy texture for the roasted onion cream when blended.
1 tablespoon nutritional yeast — gives the cream a savory, slightly cheesy note.
1 tablespoon lemon juice — brightens the cream and balances the richness of the cashews.
1/4 cup filtered water — used to thin the onion-cashew cream to a spreadable consistency.
3/4 cup chickpea flour — makes the batter that crisps the cauliflower without gluten- or dairy-based binders.
3/4 cup filtered water — mixed with the chickpea flour to reach a thin pancake-batter consistency.
Sea salt & ground black pepper, to taste — used again in the batter; balance to taste.
4 cups SMALL cauliflower florets — choose florets the size of a pinky tip so they cook evenly and get thoroughly coated.
1/2 cup Buffalo-style hot sauce — the spicy coating for the cauliflower; use a brand you like for flavor and heat level.
1 tablespoon oil — whisked with hot sauce to help it coat the cauliflower and promote browning.
1 lb pizza dough — homemade or store-bought; will be stretched to a 12-inch crust.
2 handfuls baby arugula — scattered on after baking for peppery freshness.
2 green onions, finely sliced — bright garnish that adds crunch and mild onion flavor.
Vegan ranch dressing, for drizzling and dipping (see recipe notes) — optional but recommended for cooling contrast to the heat.

Cook Buffalo Cauliflower Pizza with Roasted Onion Cream Like This

Oven setup and initial baking

1. Place an oven rack as low as possible and put a pizza stone on that rack. Place a second oven rack on the second rung from the top. Preheat the oven to 450°F.

2. Line two baking sheets with parchment paper.

Make the roasted onion cream

3. On one prepared baking sheet, combine the chopped onion, halved garlic cloves, 1 teaspoon of the oil, and a pinch of salt and pepper. Toss so everything is lightly coated and spread into a single layer.

4. Slide this sheet onto the top rack and roast until the onion edges begin to char and the garlic softens, about 15 minutes. Remove from the oven and let cool briefly so it’s safe to handle.

5. Into an upright blender place the roasted onion and garlic, the remaining 1 tablespoon of oil, the drained cashews, nutritional yeast, lemon juice, 1/4 cup filtered water, and salt and pepper to taste. Blend on high until completely smooth and silky. Taste and adjust seasoning. Scrape the roasted onion cream into a small bowl and set aside.

Make and bake the chickpea-battered cauliflower

6. While the onions roast, whisk together 3/4 cup chickpea flour, 3/4 cup filtered water, and a pinch of salt and pepper in a large bowl until smooth. The batter should resemble thin pancake batter.

7. Add the 4 cups small cauliflower florets to the batter and stir so each piece is lightly coated.

8. Use a slotted spoon to transfer the battered florets to the second prepared baking sheet, tapping off excess batter so the florets are not clumped. Spread them out in a single layer.

9. Bake the cauliflower in the oven (use the same oven set at 450°F) for 20 minutes, until the batter looks dry and is slightly browned. Remove and let cool briefly.

Toss cauliflower in Buffalo sauce and finish baking

10. Rinse the large bowl used for the batter. Combine 1/2 cup Buffalo-style hot sauce and 1 tablespoon oil in that bowl and whisk until combined.

11. Transfer the baked cauliflower into the hot sauce bowl. Break up any large clumps and discard any loose, hard baked batter bits. Toss until every floret is evenly coated in sauce.

12. Return the sauced cauliflower to the baking sheet in a single layer and bake another 15 minutes, or until edges brown slightly and the exterior feels dry. Remove and let cool slightly. Increase oven temperature to 500°F.

Shape dough and assemble

13. Dust your work surface and pizza peel with flour, or use a piece of parchment on the peel. Stretch or roll the 1 lb pizza dough into an even 12-inch circle. Transfer the dough to the floured peel or to the parchment, trimming the parchment so there’s a 1/2-inch border if using paper.

14. Spread the roasted onion cream evenly over the dough, leaving about 1/2 inch around the edge for the crust.

15. Arrange all of the Buffalo-coated cauliflower over the cream. Press florets gently into the cream so they adhere to the dough.

Bake the pizza

16. Jiggle the peel to ensure the pizza will slide. If it sticks to a floured peel, lift the edges and dust with a little more flour until it moves freely. Skip this if you used parchment.

17. Open the oven and slide the pizza off the peel onto the hot stone (or transfer using the parchment). Close the oven immediately. Bake 7 minutes.

18. Open the oven, rotate the pizza with the peel, and bake an additional 5 minutes, or until the top crust has browned in spots and the onion cream is drying near the crust.

19. Remove the pizza from the oven. Cut into slices and scatter the baby arugula and sliced green onions on top. Drizzle with vegan ranch. Serve immediately.

The Upside of Buffalo Cauliflower Pizza with Roasted Onion Cream

This pizza is bold but balanced. Roasted onion cream smooths the heat; chickpea batter gives crunchy texture without deep frying; arugula and green onions add a fresh counterpoint. It’s a great way to make cauliflower the star and to enjoy Buffalo flavor without wings. It’s also adaptable for vegan diets and works well for parties because the cauliflower keeps its shape and texture when baked a second time.

Swap Guide

Swap buffalo-style hot sauce — try a milder hot sauce or a smoky chipotle for different heat and flavor.
Swap chickpea flour — you can’t substitute the exact behavior without changing crispness; if you must, test a tempura or gluten-free all-purpose batter but results will differ.
Swap cashews — use a vegan cream cheese (softened) if allergic, but flavor and texture will change.
Swap arugula — baby spinach or peppery microgreens also work if you prefer milder greens.

Setup & Equipment

Pizza stone (or heavy baking steel) — for a blistered crust.
Two baking sheets — one for the roasted onions and one for the cauliflower.
Blender — an upright blender gives the smoothest roasted onion cream.
Pizza peel or parchment — for transferring the pizza to the stone.
Slotted spoon — to move battered cauliflower without excess batter.

Don’t Do This

Don’t overload the cauliflower on the baking sheet — crowding causes steaming, not crisping.
Don’t skip soaking the cashews — unsoaked cashews make a gritty cream.
Don’t spread too much onion cream to the edge — it should not pool or make the crust soggy.
Don’t try to flip or move the pizza mid-bake except for a single rotation; repeated opening will cool the oven and interfere with crust formation.

Spring to Winter: Ideas

Spring: top with fresh peas and mint after baking for a bright lift. Summer: add grilled corn and thin-sliced jalapeño for extra crunch. Fall: swap arugula for a handful of baby kale tossed in lemon for a heartier bite. Winter: finish with pickled red onions to cut through the richer roasted onion cream.

If You’re Curious

Why chickpea flour? It crisps up and gives a slightly nutty flavor that holds up to coating and baking. Why roast the onions first? Roasting concentrates their sweetness and softens them so they blend into a silky cream that won’t weep on the pizza. Why bake the cauliflower twice? The first bake sets the batter and partially cooks the cauliflower; tossing in hot sauce and finishing in the oven renders the sauce into a glaze and crisps the edges without sogging the crust.

Meal Prep & Storage Notes

Make the roasted onion cream up to 3 days ahead and keep refrigerated in an airtight jar. The battered cauliflower can be fully cooked and sauced, then refrigerated for up to 2 days; re-crisp on a sheet in a hot oven (425°F) for 8–10 minutes before assembling. Leftover pizza stores for 2 days in the fridge; reheat in a 375°F oven on a baking sheet until warmed through to refresh the crust. The onion cream can be frozen for up to 1 month; thaw overnight in the fridge and stir before using.
