Preheat the oven to 425F.

Make the Crust: In a medium bowl, sprinkle instant yeast over warm water. Let sit for 5 minutes. Stir in oil, salt, sugar, flour, and dill until dough comes together. Knead on a lightly floured surface for 1-2 minutes until smooth. Cover and set aside.

In a medium saucepan, melt butter and sauté garlic. Whisk in flour and cook for 1 minute. Gradually whisk in milk and add Italian seasoning, salt, and pepper. Cook until thickened, about 4-5 minutes. Stir in Parmesan until melted.

Roll out dough to a 12-inch circle. Place on a lightly oiled pizza pan. Spread white sauce over the dough, leaving a 1/2 inch edge. Sprinkle mozzarella cheese and place dried pickle slices on top.

Bake on the middle rack for 15-20 minutes or until cheese is melted and lightly browned.

While the pizza bakes, mix sour cream, mayonnaise, minced garlic, dill pickle juice, and fresh dill in a bowl.

After baking, sprinkle with crushed red pepper and chopped dill if desired. Drizzle creamy garlic sauce over the pizza and serve additional sauce on the side.
