Preheat your oven to 400°F. Remove pie crusts from refrigerator and let them sit at room temperature for 15 minutes to soften slightly.

Peel, core, and slice the apples into 1/4-inch pieces. Place in a large bowl and toss with lemon juice to prevent browning.

Mix the cinnamon, sugar, and flour together, then toss with the apples until evenly coated. Transfer to a medium saucepan, top with butter, cover, and simmer over medium heat until apples are soft.

Unroll pie crusts on a lightly floured surface. Using a 3.25-3.5 inch biscuit cutter, cut out 12 circles. Gently press each circle into the cups of a standard muffin tin.

Fill each crust with about 2 tablespoons of apple filling. From remaining dough, either cut thin strips to create a lattice pattern or use a smaller 2.5-inch cutter to create top crusts.

Whisk together egg and water to make an egg wash. Brush over the tops of each pie, then sprinkle with turbinado sugar. Place muffin tin on a parchment-lined baking sheet and bake for 15 minutes until golden brown.
