Set the oven to 425 °F and let it reach temperature before baking. A fully heated oven helps the crust and cheese finish together.
Blend the cream cheese, pickle juice, garlic, dried dill, salt, and pepper in a mini food processor, or combine them in a bowl with a spoon or hand mixer. The finished spread should look smooth and glossy, without firm cream cheese lumps.
Set the crust on a sheet pan and coat it with the cream cheese spread, keeping a 1/2-inch rim uncovered and reserving 1 to 2 teaspoons for finishing if desired. An even coating protects against thick pockets of sauce, while the bare rim keeps the garlic mixture away from the exposed edge.
Distribute the mozzarella over the sauce, then arrange the dried pickle slices and finish with Parmesan and a pinch of dried dill. Space the pickles across the cheese so the toppings form an even layer rather than a mound in the middle.
Bake for 8 to 10 minutes, checking for melted cheese and a thoroughly heated pizza. Look for gently bubbling mozzarella and golden Parmesan edges without letting the garlic spread scorch.
Drizzle on the reserved cream cheese mixture, if any, and add chopped fresh dill if using. The finishing drizzle adds tang, while the fresh dill supplies a bright herbal aroma.
Wait 2 to 3 minutes before dividing the pizza into four slices. This brief rest lets the melted cheese settle so the pickles stay in place when you cut.
