Special equipment: a round aluminum pizza pan or a wooden pizza peel and pizza stone
For the dough: In an electric mixer fitted with a dough hook, dissolve the yeast in the water until there are no pieces of yeast left. Add the flour and start mixing on low. After the flour and water have started to mix, add the salt. Let mix for another minute until all of the flour from the sides of the bowl have been incorporated. If the dough is sticking to the side of the bowl, add flour slowly until it starts to firm up around the dough hook. Add the olive oil and mix for another 5 minutes.
Let the dough rest in the bowl, covered, for 10 minutes. In the meantime, spray a baking sheet or aluminum pan with cooking spray. After the dough is done resting, empty it onto a lightly floured prep surface. Weigh the dough out into three 10-ounce portions. In your hands, fold the dough into itself, tightening the dough and removing air pockets with each fold. Add flour to your hands if the dough is too sticky. When the dough is tight enough to hold its shape, put it on to the greased baking sheet and spray the top with a little of the cooking spray. Cover with plastic wrap and let proof at room temperature for 1 to 1 1/2 hours. The dough should at least double in size. You can also proof in the fridge overnight and leave it out 30 minutes before you are ready to use it the next day.
For the garlic ricotta: While the dough is proofing, make the roasted garlic ricotta, sliced zucchini and charred red onions. (Start roasting the garlic right away as it will take the most time.)
Preheat the oven to 400 degrees F.
Cut off the tops of the heads of garlic. Drizzle the olive oil over the tops of the garlic, wrap in aluminum foil and roast for 45 minutes to 1 hour. Once tender, remove from the oven and let cool. In a stainless bowl, squeeze out the roasted garlic. Add a splash of oil and a pinch of salt and pepper. Using a spatula, smooth the garlic into a paste in the bowl. Add the ricotta and fold in the garlic until it is completely incorporated.
For the charred red onions: Turn the oven temperature up to 500 degrees F. Cut the ends off the onions, and peel off the tough outer layer. Cut in half lengthwise and thinly slice. Toss in olive oil and cook on a baking sheet in the oven of 15 to 20 minutes until you see a good bit of charred pieces. Cool.
For the zucchini: While the onions cook, cut the ends off of the zucchini and squash and thinly slice on a bias. Toss in a metal bowl with the olive oil, pepper flakes, lemon zest and salt and pepper.
To assemble the pizza: Leave the oven temperature at 500 degrees F, and lightly flour a smooth work surface. Take out one of the dough balls. Starting at the edges, gently press down on the dough, being careful not to pull at it. Continue pressing the edges and work towards the center, keeping the dough round. Make sure to flour both sides at least twice during this process. Once you've stretched the dough to about 14 inches, move it onto a round aluminum pizza pan or a wooden peel if you plan on sliding it on to a pizza stone.
Start assembling the pie by spreading the ricotta mixture all over the base. Place several slices of fresh mozzarella evenly over the crust. Next, add the cut zucchini and squash and charred red onions. Drizzle with olive oil and place in the oven on the aluminum pan or if using a pizza stone, slide on from the wooden peel. Let bake for about 10 minutes, then slide the pizza right onto the oven rack and cook for another 5 to 10 minutes or until the crust is golden brown. Repeat with the remaining ingredients.
