Why You’ll Love This Fall Cauliflower Pizza

  • All the cozy fall flavors — butternut squash, Brussels sprouts, prosciutto — on a crispy, gluten-free crust
  • A gorgeous, restaurant-worthy pizza that’s actually easy to pull off at home
  • Low-carb and gluten-free without sacrificing any flavor
  • Perfect for fall dinner parties or a special weeknight treat

Ingredients You’ll Need

  • Cauliflower crust — store-bought or homemade; pre-bake until golden for best crispiness
  • Butternut squash — roasted until caramelized and sweet
  • Brussels sprouts — thinly sliced or shaved for even roasting
  • Prosciutto — adds salty, savory depth and crisps up beautifully in the oven
  • Mozzarella — the creamy, melty base
  • Olive oil + garlic — a simple sauce that lets the toppings shine

Tips for the Best Results

  • Roast the squash and Brussels ahead — gives them a head start on caramelizing before the pizza goes in the oven
  • Pre-bake the crust — always bake cauliflower crust before adding toppings to prevent sogginess
  • Add prosciutto in the last 5 minutes — or place it on after baking so it stays delicate rather than tough
  • Don’t overload — a lightly topped cauliflower pizza holds up better and stays crispier

Substitutions & Variations

  • Acorn squash or sweet potato — great substitutes for butternut squash
  • Pancetta or bacon — swap for prosciutto for a more intense smoky flavor
  • Gruyère or fontina — beautiful fall cheese alternatives to mozzarella
  • Add a drizzle of balsamic glaze — the finishing touch that ties all the fall flavors together

Frequently Asked Questions

Can I prep components ahead of time?

Yes! Roast the butternut squash and Brussels sprouts up to 2 days ahead. Store in the fridge and bring to room temperature before topping the pizza. This makes weeknight assembly super fast.

What’s the best way to slice Brussels sprouts for pizza?

Trim the ends, remove any outer leaves, and thinly slice them on a mandoline or with a sharp knife. Shaved Brussels sprouts roast faster and lay flat on the pizza better than halved ones.
