Get your smoker preheated to 350°F.
Put that pie crust into your smoker for about 25 minutes, just until it starts to turn a nice golden brown. Then, take it out of the smoker. (Skip this step if using pre-baked pie crust like graham cracker crust)
Grab your mixing bowl and combine your pumpkin puree, eggs, evaporated milk, and that lovely pumpkin spice mix. Give it a good stir until it's all mixed up.
Now, lower the heat on your smoker to 300°F.
Pour your delicious filling into your pre-baked pie crust.
It's time to put the pie back into the smoker for another 1¼ hours. You'll know it's ready when a toothpick inserted 2" from the crust comes out clean. If the center is a little wobbly, that's okay. It'll firm up once cooled.
Let the pie chill in the fridge for about 2 hours. After that, it's ready to serve!
