We have one that makes a thick soup - it can be watered down to the right consistency with milk.
Cut top off pumpkin to make a lid (so it sits in the top)
Scoop out all seeds from lid & in pumpkin
In the pumpkin add
1 tin Reduced cream
1-2tsp crushed garlic
1 pkt onion soup
2 slices of bread - cubed
1 cup grated cheese
Mix all together in the pumpkin, put onto a baking tray (Place a bread crust under the bottom so it doesn't burn) Bake at 180 for 1.5-2hours, or until the flesh comes away from the side when it's mixed into the centre of the pumpkin - you can put the oven up higher if you are gettin impatient!
Once the flesh is coming away take pumpkin out of the oven & scoop all the flesh into the centre of the pumpkin mixing it with the reduced cream mixture... once its all mixed it can be used as a vegetable the first night, then blended with milk as a soup.
If you dont take ALL the flesh off the sides of the pumpkin you can breakdown the sides, grate cheese with a bit of curry powder on top & grill - tastey snack
Alterations
If you think its too sweet you can use the equivalent of cream instead of reduced cream, and you can dice an onion if you dont have the packet soup
Mum has been making this for years, it can be frozen either in the thick form (cubes are good as you can de-frost a couple into a cup of milk), or the thinner form.
