Tips
Caramelize onions slowly over medium heat, stirring frequently, for deep sweetness that balances the pizza's smoky heat. Rushing this step produces raw, bitter onions instead of jammy, sweet ones.
Process the kabocha squash mixture until completely smooth for even distribution and creamy texture. Chunky sauce pools unevenly and creates dry spots on the finished pizza.
Reserve some cheese for the final layer to ensure even melting and golden color. Distribute across the top rather than clumping to prevent overcooked edges while the center remains barely melted.
Good to Know
Cover and refrigerate up to 3 days. Reheat in a 350-degree F oven for 8-10 minutes until warmed through.
Prepare kabocha squash puree and caramelize onions up to 1 day ahead. Assemble and bake just before serving for best crust texture.
Cut into slices and serve warm, optionally with a drizzle of hot sauce or a side salad.
Common Mistakes
Skip stirring the polenta mixture before spreading to avoid lumps and ensure even thickness on the pan.
Do not overbake after adding toppings to prevent the crust from becoming hard and cheese from separating.

FAQ
Can I make this pizza ahead of time?
Yes. Prepare the kabocha squash puree and caramelize onions up to 1 day ahead and refrigerate separately. Assemble and bake the pizza the day you plan to serve it for the best texture and crispy crust.
What if I don't have fresh sage?
Sage is optional and adds herbaceous flavor. Substitute with fresh thyme, oregano, or basil, or omit entirely. The pizza is fully satisfying without it.
Can I freeze leftover pizza?
Yes. Cool completely, wrap slices individually in plastic wrap and foil, and freeze up to 3 months. Thaw overnight in the refrigerator and reheat in a 350-degree F oven until warmed through.
