01 - Preheat oven to 480°F or to the highest setting available. If using a pizza stone, position it in the oven before heating.
02 - On a lightly floured surface, stretch or roll the pizza dough into a 12-inch round. Transfer to a parchment-lined baking sheet or pizza peel.
03 - In a small mixing bowl, combine crème fraîche, minced garlic, chopped dill, lemon zest, salt, and black pepper until fully incorporated.
04 - Evenly distribute the crème fraîche sauce over the dough, leaving a 1/2-inch border uncovered.
05 - Sprinkle shredded mozzarella cheese uniformly over the sauce.
06 - Arrange sliced dill pickles and red onion, if using, across the surface of the cheese.
07 - Bake for 12 to 15 minutes, or until the crust turns golden and cheese bubbles.
08 - Remove from oven, garnish with fresh dill, slice into portions, and serve hot.
