Step 1: In a large bowl, whisk together the bread flour, instant yeast, and salt. Add the warm water and 2 tablespoons of olive oil, stirring until a sticky dough forms.
Step 2: Cover the bowl with a damp cloth and let the dough rise in a warm spot for about 1 to 2 hours, or until it has doubled in size.
Step 3: Pour 3 tablespoons of olive oil into a 10-inch or 12-inch cast-iron skillet, ensuring the bottom and sides are well-coated.
Step 4: Transfer the dough to the skillet. Gently press it toward the edges. If it resists, let it rest for 10 minutes and try again until it covers the bottom of the pan.
Step 5: Cover the skillet and let the dough rise for another 30-45 minutes. This step creates the signature airy texture of the Vegan Pepperoni Skillet Pan Pizza.
Step 6: Preheat your oven to 475°F (245°C). Spread the pizza sauce over the dough, going almost all the way to the edges.
Step 7: Sprinkle the vegan mozzarella evenly over the sauce and layer the vegan pepperoni slices on top. Season with dried oregano.
Step 8: Bake for 18-22 minutes on the bottom rack of the oven until the crust is golden-brown and the cheese is melted and bubbling.
Step 9: Remove from the oven and let rest in the pan for a few minutes before sliding onto a cutting board. Slice and serve your Vegan Pepperoni Skillet Pan Pizza immediately.
