Note: The Apple Pie Filling can be made at any time and refrigerated until ready to add to the pie pan. See Note/Warning if using a glass pie pan before you begin.: The filling's aroma while cooking will be heady and warm, with steam carrying notes of cinnamon and caramelized sugars. Preparing it ahead lets the flavors meld and the juices cool into a syrup, which makes handling easier and improves the final texture. A frequent mistake is rushing the cooling; if the filling is too warm, it can soften the crust and cause the pie to be messy when sliced. Watch for a gentle simmer and avoid high heat, which can break down the apples too quickly and produce a mushier texture than desired.
Make the Pie Dough: Prepare one pie crust recipe through step 6 under Make Dough (click HERE for the recipe.) Prepare the second pie crust through step 2 under Roll Dough using a standard 9-10-inch pie pan (1 1/2-inches deep).: While making dough, you should notice a shaggy mass coming together that feels cool from the butter bits, and a faint flour scent turning richer as fat disperses. Chilling at this stage firms the butter, which creates steam pockets when baked, yielding flakiness. A common error is overworking the dough, which warms the butter and develops gluten, causing toughness, so handle it with light, quick motions and rest the dough until firm and cool.
Make the Bottom Pie Crust: Lightly brush the bottom and sides of the crust in the pan (not edges that will be fluted) with the egg wash. Reserve the egg wash in the refrigerator for later. Tip: I find it easiest to add the egg wash after the pie dough has firmed up a bit, so I place the pie in the freezer for 20 minutes. After adding the egg wash, immediately cover the pie and refrigerate it while you prep the rest of the recipe (at least 45 minutes up to 5 days before baking).: Brushing the shell adds a protective layer so juices are less likely to soak into the crust. You may hear a soft tacky sound as the wash is applied, and visually you should see a thin glossy coating. Many bakers skip chilling before adding the wash, but I find freezing the shell for 20 minutes makes the application cleaner and reduces shrinkage during baking. Avoid adding the wash to the fluted edge at this time if you plan additional crimping, or it may seal too tightly and interfere with decorative edges.
Roll Out the Dough for the Lattice Top: Place a large piece of parchment paper on a baking sheet and generously dust with flour. Roll the dough disc into a rough 11×11-inch rectangle on the parchment paper. At this point, I cover and freeze the dough (on the baking sheet) for 20-30 minutes for easier/cleaner slices.: Rolling the dough on parchment simplifies transfer and keeps the surface smooth, while the generous dusting prevents sticking and tearing. You'll feel the dough relax under the rolling pin, and the surface should look slightly tacky but not wet. If the dough becomes sticky, pop it in the freezer for 20 to 30 minutes; attempting to force a sticky sheet will cause ragged edges and a less attractive lattice.
Make the Lattice Strips: After chilling, use a ruler and a pizza cutter, pastry wheel, or sharp knife to cut the dough into 1-inch-wide strips. Cover with plastic wrap and freeze for 30 minutes or refrigerate for up to 24 hours for MUCH easier-to-handle lattices. When you're ready to use the lattices, make the apple pie filling first:: Cutting precise 1 inch strips creates even browning and a tidy weave. The strips should feel firm but flexible; if they crack, let them rest at room temperature briefly to relax. Freezing the strips before weaving reduces stretching and preserves clean edges. A common misstep is trying to stretch strips to cover more area, which leads to thin, fragile pieces that tear during assembly.
Slice the apples: Peel the apples and make 4 slices around the core to remove it. Lay the 4 remaining apple segments, cut side down, on a cutting board, and slice into 1/8-inch slices. Transfer the apples to a large Dutch oven as you go to keep the workspace clean.: The rhythm of slicing produces thin, uniform pieces that are easy to layer. You will notice the apples releasing a sweet, fruity scent and a slight snap as the knife moves through. Keeping the slices thin and consistent promotes even cooking and texture. A pitfall here is uneven thickness; thicker pieces may not reach the same tenderness and can compromise the mouthfeel of the filling.
Apple pie filling: Add the sugars, flour, 1 tablespoon of lemon juice, and spices to the sliced apples and set over medium heat. Gently stir until evenly coated. Cover and cook for 15-20 minutes, stirring every couple minutes and replacing the lid. The apples are done when they reach YOUR desired apple pie tenderness – they will not become more tender in the oven. They should be fork-tender but still hold their shape. (They will not become mushy when baked; see the science behind it in the post.) Once tender, stir in the remaining 1 tablespoon of lemon juice and the vanilla.: As the filling cooks, the room will fill with a warm, spiced perfume and the apples will begin to soften, making a gentle bubbling sound in the pot. Stirring helps the sugars dissolve and coat each slice evenly, and the heat releases pectin that will later help the filling set. Avoid high heat, which can caramelize the sugars too fast and leave tough edges on the apples. Stir every couple minutes so nothing sticks and the apples cook uniformly.
Cool the Apples: Line a rimmed baking sheet with parchment paper or a silicone baking mat for easy cleanup. Transfer the apples and their caramel juices to the baking sheet. Pop the pan in the fridge or freezer to cool to room temperature for about 25 minutes.: Spreading the apples on a cooled surface arrests cooking and concentrates the juices visually into glossy ribbons. Cooling for about 25 minutes brings the filling to a manageable temperature so it will not melt the chilled crust. A common oversight is not cooling enough, which can cause a soggy bottom crust, so allow the full rest time and check that the mixture has come down to room temperature before assembly.
Assemble: Once the apples have cooled, transfer them and the sauce to the chilled pie shell, rearranging and layering them horizontally to compact.: Layering horizontally compacts the slices and helps the pie slice cleanly, creating a dense but tender interior. You should hear the light settling of apples as they nestle together, and the filling will glisten with syrup. Avoid overfilling the shell, which can cause juice to spill and make the crust soggy; leave a small gap to accommodate bubbling during baking.
Weave the Lattice Top (See Post for Photos): If the strips become too stiff to work with, let them rest on the counter for 10 minutes. Start by laying five horizontal strips evenly spaced over the pie (center the middle strip). Fold the first, third, and fifth horizontal strips back and place a vertical strip on the left side. Unfold the first, third, and fifth strips over the perpendicular strip and fold the second and fourth strips back. Add a second vertical strip, then unfold the second and fourth strip. Repeat the process for a total of ten strips, five running in each direction.: Weaving a lattice adds texture and vents for steam to escape, and the woven pattern bakes into a crisp grid that contrasts with the soft filling. If strips are cold and too stiff, they will crack, but if too warm they will stretch and lose shape; allow them to temper until flexible. A typical mistake is forcing a stiff strip, which tears, so be patient and let the dough rest if needed.
Make the Edges: Press the edges of the strips into the edges of the crust to seal. Flute, crimp, or create whatever edge design you prefer. Lightly brush the edges and the lattice top with the egg wash. Sprinkle the lattice top (avoid the edges) with coarse sugar if using.: Sealing the edges prevents leaks and gives the pie a finished look. The edges should feel secure under gentle pressure and the design should look uniform. Brush the top lightly with the reserved egg wash and add coarse sugar if desired for sparkle. Overworking the rim can compress the dough and make the crust dense, so handle edges with a light touch.
Refrigerate: Chill the unbaked pie for 30 minutes. Don’t skip this step—it will help the crust not shrink unless you have a glass pie pan. Then, bake without chilling, or the pan can shatter (see Notes).: Chilling firms the butter and relaxes the dough, which helps prevent shrinking and keeps the lattice crisp. You may notice the pie feeling colder to the touch and a slight tightening of the dough surface as it rests. Skipping this step often results in a misshapen or shrunken crust, so set a timer and allow the full 30 minutes unless you are using a glass pan that requires a different approach.
Preheat the Oven: Immediately after transferring the pie to the fridge, place a baking sheet on the bottom rack of your oven and preheat the oven to 425 degrees F so the baking sheet can get very hot.: Preheating the oven and a hot baking sheet jump starts the bottom crust into steam production, promoting flakiness and preventing sogginess. The oven will emit a dry heat smell and the baking sheet will become radiantly hot. A common rookie mistake is putting the pie in a cold oven, which leads to long, soggy bake times and a greasy bottom crust.
Bake: Transfer the chilled pie to the rimmed baking sheet. Bake at 425 degrees F for 25 minutes (keep an eye on the crust so it doesn't become too brown). Reduce the heat to 375 degrees F and continue to bake for 35-45 minutes or until the filling is bubbling around the edges (if you don’t wait for it to bubble, your filling will be runny). Cover the edges with a pie shield or the top with foil if they are browning too quickly.: During baking you should see the lattice turn golden brown and the filling begin to bubble vigorously at the edges, signaling a properly thickened interior. If the crust darkens too fast cover the edges with foil to prevent burning. Not waiting for the filling to bubble is a common error that results in a runny pie, so watch for active bubbling as your cue to finish the bake.
Cool: Transfer the pie to a cooling rack and let it rest for 4 hours to cool to room temperature so the filling can set. You can pop the pie in the fridge or freezer to speed up the cooling process. The pie can rest at room temperature for up to 2 days or be refrigerated for up to 5.: Cooling quietly completes the set of the filling and concentrates the flavors, and you will notice the juices thicken and the slices hold shape. Slicing too soon makes the pie sloppy, so patience at this stage is rewarded. If you need to speed things, briefly chill in the fridge or freezer, but avoid cutting while still warm to keep clean slices.
Reheat: After the pie has cooled, you can reheat/refresh it in the oven. Tent the pie with foil and place it in a cold oven. Turn the oven to 375 degrees F, and when the preheat bell dings, leave the pie in for another 10-15 minutes or until warmed.: Reheating restores warmth and revives crispness in the crust, and you will detect the aromas returning as the pie warms. Leaving it tented keeps the top from overbrowning while the center heats through. A mistake is reheating too long or at too high a temperature which can dry out the filling and toughen the crust.
