First, make the pizza dough. In a glass measuring cup or small bowl, combine yeast and 1 cup warm water. Add a pinch of sugar and let sit for 5 minutes.: You will notice a slight froth and yeasty aroma forming on the surface, which is the reassuring sign the yeast is alive and active. The warm water should feel comfortable to the wrist, and that gentle warmth helps the yeast bloom into bubbles, giving the dough lift. As you wait, the scent turns mildly sweet and bready, and that scent is a good indicator of readiness. If nothing happens after five minutes, the yeast may be old or the water too hot or too cold. Do not rush forward with inactive yeast, or the crust will remain dense and pale. A common mistake here is using water that is too hot, which can kill the yeast instantly, so test the temperature carefully.
In the bowl of a stand mixer, add the flour and salt. Mix the ingredients until combined.: When you blend the flour and salt, the mixture should look even and fine without pockets of salt. This step ensures the salt will season the entire dough and prevents patches of over salted dough. The dry mixture smells clean and wheaty, and once combined it is ready to accept the liquid. A frequent oversight is adding salt directly onto the yeast during activation, which can inhibit it, so keeping them separate is wise.
Add the yeast mixture to the flour mixture. Next, add 1 tablespoon of olive oil. Mix until combined. Switch to the dough hook and knead for about 5 minutes on medium speed.: As the dough takes shape, it will go from shaggy to a cohesive mass, soft and slightly tacky to the touch. The motion of the dough hook develops gluten, and you will see the dough pull away from the bowl and form a smooth surface. The sound changes too, from splattering to a low, steady thunk as the hook works. Under kneading leaves a crumbly texture, while over kneading can produce a tough crust, so aim for that sweet spot where the dough is stretchy and springs back when poked.
Spray a large bowl with cooking spray. Form dough into a ball and place in the bowl. Cover pizza dough with a damp towel and set in a warm area to rise. Let the dough rise for 1 hour or until dough has doubled in size.: The dough should become noticeably puffy and airy, almost doubled in volume, with a slightly domed top and soft, tender skin. The aroma deepens into a richer dough scent, and pressing gently will leave a faint indentation that springs slowly back. Rising time depends on room temperature, so a cool kitchen may require a bit longer. Avoid letting the dough overproof, which causes weak structure and a collapsed crust when baked.
Preheat the oven to 450 degrees F. Cut the dough in half. Take one piece of dough and punch it down on a lightly floured surface. You can refrigerate or freeze the other half of the dough or make 2 pizzas, if you wish. Using a rolling pin, roll the dough out into a circle. Place the pizza dough on a pizza pan or pizza stone.: The preheated oven readies the environment for immediate oven spring and browning. When you punch the dough down, you release large gas bubbles and create a denser, more even crumb. Rolling the dough thin will produce a crisper crust, while leaving it slightly thicker yields a chewier interior. Transfer it carefully to a pan or stone dusted with corn meal so it slides easily. One common error is over flouring the surface, which can dry out the dough and prevent good browning.
Evenly brush the olive oil on the pizza. Top with fresh mozzarella slices. Add the parmesan cheese. Place the pizza in the oven and bake for 12-15 minutes or until pizza crust is golden and cheese is melted.: As the pie bakes, you will hear gentle bubbling and see the mozzarella melt into glossy pools while the crust develops golden blisters and a toasty aroma. The olive oil on the surface encourages even browning and a crisp edge. Watch for the cheese to be fully melted and the crust edges to take on a warm amber hue, that is the cue to pull it. Avoid leaving it unattended for too long, as cheese can over brown and the crust can harden if overbaked.
Remove the pizza from the oven and place arugula on top. Squeeze fresh lemon juice over the arugula and season with salt and black pepper, to taste. Garnish with additional parmesan cheese, if desired. Cut into slices and serve.: The residual heat will slightly wilt the arugula so it softens without losing its peppery snap, and the aroma of citrus will brighten the whole pie. Toss the greens with the lemon juice briefly so they are evenly dressed, then distribute them across the hot pizza so each slice carries that fresh contrast. Season thoughtfully because the cheeses already add salt, and a light hand with pepper will enhance rather than overpower. A frequent mistake is adding too much lemon, which can take over the delicate balance.
Note we made a thin crust pizza. Josh rolled the crust into about a 13-inch circle. If you want a thicker crust, don't roll it out as far.: The final sprinkle of extra Parmesan cheese provides an added savory note and a slight granular texture against the melted mozzarella . Cutting through the golden crust releases fragrant steam and creates neat slices that highlight the topping contrast. Serve immediately while the cheese is warm and the greens remain fresh. Waiting too long can lead to a soggy base as the toppings settle, so enjoy while hot.
Note we made a thin crust pizza. Josh rolled the crust into about a 13 inch circle. If you want a thicker crust, don't roll it out as far: You can judge thickness visually as you roll, aiming for an even edge and uniform center so the bake is consistent. A thinner roll yields crispness and a larger surface for toppings, while a thicker roll gives a chewier interior; both are delicious depending on your preference. If you opt for thick, expect slightly longer bake time and a softer crumb. Avoid uneven rolling, which creates hotspots that brown before the center is done.
