You could swap out the butter for olive oil to cook the onions but the butter adds a richness to the caramelized onions. You could also use bacon fat to add extra smokiness to the pizza.
Swap out the ricotta and butter for your preferred substitute, or omit entirely. Drizzle a bit of extra olive oil on the dough before topping with ingredients.
Use your favorite premade gluten free pizza dough or make your own with this mix from Bob’s Red Mill (<-affiliate).
While this is a tremendously filling pizza that doesn’t need extra protein, cooked Italian sausage or chicken apple sausage would complement the flavors of the sage and butternut squash.
Other squash such as acorn or delicata would be excellent with this pizza. Try it with a smoked gouda if you don’t have smoked mozzarella. Even broccoli could be swapped for the kale in this butternut squash pizza.
Instead of store bought dough, you can make your own dough with this simple pizza dough recipe. Or try my favorite sourdough pizza crust from King Arthur Flour! I usually get 2 pizzas from this recipe, enough for 4 to 6 servings.
