Preheat your oven to 400 F. Then, peel the butternut squash and then scoop out the seeds. Chop into 1-inch sized cubes and add to a baking sheet. Drizzle with olive oil, salt, pepper, and paprika. Bake for 40 minutes, flipping halfway.
Add 2 tbsp vegan butter or olive oil to a saucepan. Allow to melt on medium-low heat. Chop your white onions into thin strips. Add the onions into the saucepan and reduce the heat to low. Cook and continuously stir until the onions turn brown. Once caramelized, turn off the heat and set aside.
For the cashew ricotta, add 3/4 cup raw cashews to a saucepan and boil the water. Allow the cashews to boil for about 10 minutes then remove from heat. In a food processor or blender, add the cashews, water, 1 tbsp lemon juice, 1 tbsp minced garlic, 1 tbsp garlic powder, salt and pepper. Blend until creamy and it should be a hummus-like consistency. Place the ricotta in the fridge for one hour to thicken up before serving.
Next, prepare the balsamic glaze. Mix together the balsamic vinegar, maple syrup, olive oil, and thyme in a small bowl. Set aside.
Once the butternut squash is done in the oven, reduce the oven heat to 350 F.
Begin to assemble the pizza. Spread out the balsamic glaze on the pizza crust. Top with the caramelized onions, butternut squash, and spinach. Bake for 10-12 minutes or until the edges of the crust turn golden brown.
After the pizza is done baking, top with the cashew ricotta. Serve and enjoy!
