Step 1: Prepare the Dough
Preheat your oven to 475°F (245°C) and place a pizza stone or baking sheet inside to heat up. If using store-bought pizza dough, allow it to come to room temperature for about 20-30 minutes. Roll the dough out on a floured surface to your desired thickness (about 12-14 inches in diameter for a standard pizza). Lightly brush the edges with olive oil for a crispier crust.

Step 2: Make the Alfredo Sauce (Optional)
If you prefer making your Alfredo sauce from scratch, melt 2 tablespoons of butter in a saucepan over medium heat. Add 2 minced garlic cloves and sauté for about 1 minute until fragrant but not browned. Stir in 1 cup of heavy cream and bring the mixture to a simmer. Gradually whisk in ¾ cup of freshly grated Parmesan cheese until fully melted and smooth. Season with salt and pepper to taste, and allow the sauce to thicken for 2-3 minutes. Remove from heat and set aside.

Step 3: Prepare the Toppings
In a skillet, heat 1 tablespoon of olive oil over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant. Toss in the fresh spinach leaves and cook until wilted, about 2-3 minutes. Remove from heat and set aside.

If your grilled chicken is not pre-cooked, grill or pan-sear the chicken breasts, seasoning them with salt, pepper, and Italian seasoning. Cook for about 6-8 minutes per side until fully cooked through. Allow the chicken to rest for a few minutes before slicing or cubing.

Step 4: Assemble the Pizza
Spread a generous layer of Alfredo sauce (store-bought or your homemade version) evenly over the rolled-out pizza dough, leaving about ½ inch around the edges. Top the sauce with half of the shredded mozzarella cheese. Evenly distribute the grilled chicken pieces and sautéed spinach over the cheese layer. Sprinkle the remaining mozzarella cheese and grated Parmesan over the top.

Step 5: Bake the Pizza
Carefully transfer the assembled pizza to the preheated pizza stone or baking sheet. Bake for 10-12 minutes, or until the crust is golden brown and the cheese is bubbly and slightly browned. Keep an eye on the pizza as baking times may vary depending on your oven.

Step 6: Serve and Garnish
Remove the pizza from the oven and let it cool for a couple of minutes before slicing. For added flavor, sprinkle with red pepper flakes and an extra drizzle of olive oil, if desired. Serve immediately while the pizza is hot, with a crisp crust and melty cheese.
