Making Garlic-Ranch Chicken Pizza is straightforward if you follow these simple steps:

1. Preheat your oven to 450°F (232°C). If using a pizza stone, place it in the oven as it heats.
2. Prepare the Chicken: In a bowl, combine the shredded chicken, minced garlic, olive oil, salt, and pepper. Mix well to ensure the chicken is evenly coated.
3. Roll Out the Dough: On a floured surface, roll out your pizza dough to your desired thickness. Transfer it to a parchment-lined baking sheet or a pizza peel if using a stone.
4. Spread the Ranch Dressing: Evenly spread the ranch dressing over the pizza dough, leaving a small border around the edges.
5. Add the Chicken Mixture: Distribute the garlic and chicken mixture evenly over the ranch dressing.
6. Top with Cheese: Sprinkle mozzarella and cheddar cheese over the chicken layer, ensuring an even distribution.
7. Bake the Pizza: Place the pizza in the oven (or on the pizza stone) and bake for 12-15 minutes or until the crust is golden and the cheese is bubbling.
8. Cool and Garnish: Once baked, remove the pizza from the oven. Let it cool for 5 minutes before garnishing with chopped green onions.
9. Slice and Serve: Cut the pizza into slices and enjoy!

These steps will guide you in creating this incredible pizza effortlessly.
