I always start by preheating my oven to 425°F so it's fully ready when the pie goes in. While it heats, I fit my refrigerated pie crust into a 9-inch pie dish, crimping the edges with my fingers for that classic ruffled look. If the dough feels too cold and cracks, I let it sit out for a few minutes to soften slightly.
In a large mixing bowl, I whisk together the canned pumpkin, sweetened condensed milk, and eggs until the mixture is completely smooth. Then I add the pumpkin pie spice and salt, whisking again until everything is fully combined. I like to tap the bowl on the counter a few times to release any trapped air bubbles.
Once the filling is silky and lump-free, I pour it straight into the prepared pie crust. I use a spatula to smooth the top so it bakes evenly. At this point, I also loosely tent the crust edges with foil so they don't burn before the center sets.
I bake the pie at 425°F for the first 15 minutes, which helps set the crust. Then I lower the oven to 350°F and continue baking for another 30 to 35 minutes. I know it's done when the edges look set but the very center still has a slight jiggle.
After baking, I let the pie cool on a wire rack at room temperature for about an hour. Then I transfer it to the fridge for at least 2 hours, though I usually let mine chill longer. This resting time is what gives the filling that clean, sliceable texture.
