Step 2: Baking and Waiting
Line a large pan with the tin-foil. This is kinda optional, but it saves a lot of time in clean up since the juices will run out and burn during baking. Because of the juices, you'll want to use a pan that has edges to it, not just a flat cookie sheet.
Lay your pumpkin halves face down on the pan.
Set the oven to around 350 degrees, or around 180 Celsius.
Stick the pan in the oven, and then wait for about an hour and a half to 2 hours. The actual time will vary depending on how thick your pumpkins are and how hot your oven actually gets.
You can check the pumpkins every so often to see if they are tender by sticking a fork in them.
Once they're nice and soft that means they're done.
