This pumpkin pesto soup is easy to make for a cosy fall lunch or dinner. It makes the most of fresh pumpkin by pairing with the herbs and garlic of pesto. A vegan (using vegan pesto), gluten-free and low histamine soup recipe.
Soups are always so cosy during fall, and our family loves it as a lunch idea or light dinner. If you are a soup lover too then you may like to see my butternut squash and apple soup, parsnip and ginger soup and my broccoli and cauliflower soup. Both full of healthy goodness and so tasty too!
New pumpkins, and new recipe ideas
I thought I was all done with pumpkin recipes this year, but then a trip out to the countryside to Castle Farm made me want to do one more . . .
Their pumpkin displays are so pretty, and so of course I had to buy
one or two at least five (!) more pumpkins and squash to bring home to cook.
The lady in the farm shop gave me a recipe card for pumpkin pesto soup that sounded delicious. I've changed it up a fair amount here to make it a bit more hearty with extra veg and potato, and used coconut milk in place of dairy milk so that is vegan. I hope you enjoy for a fall lunch or dinner!
Ingredients for pumpkin soup
This easy fall soup combines fresh vegetables with vegetable broth, herbs and coconut milk. You can either use store-bought pesto or make your own.
You will need:
- Pumpkin: the food for fall! I used a pumpkin that was around 1kg in weight for this recipe.
- Onion: for the base of flavour. It is higher fodmap, so leave out if it is an issue for you.
- Potato: to thicken and make the soup a bit more hearty.
- Carrot and celery: for some added vegetables and flavour.
- Turmeric and thyme: to add flavour as well as some health benefits.
- Vegetable broth: if you follow a low histamine diet then be careful about ingredients, or perhaps make your own. Or use water with added herbs and salt.
- Coconut milk: for that creamy taste!
Step by step instructions
I think of this soup as a two-stage recipe, but one that is very simple. Before making the soup you want to make your pesto, and there are suggestions below for vegan and gluten-free recipes. Of course, you can simply use a store-bought one too.
Once you have pesto ready, then you can begin to make the soup.
In a large pot fry the onion and garlic in olive oil, and then add the turmeric and thyme. Stir to combine.
Add the celery, pumpkin, potato and carrot, and cook for a few minutes. Pour in the vegetable broth and bring to a boil. Reduce the heat and have on a light simmer for 30 minutes.
Pour in the coconut milk and a spoonful of pesto (or two spoonfuls if you want it more pesto flavour). Stir to combine, and let it warm through for a few minutes (adding the coconut milk will cool the temperature slightly). Use an immersion blender to blend into your soup.
Then simply ladle into your bowls and top with a little more pesto.
Pesto recipe suggestions
You can of course use store-bought pesto for this recipe, and there are many vegan versions available now if you have that dietary requirement.
For those here for the low histamine aspect of the recipes, you may prefer to make your own. Some suggestions for pesto recipes here on the blog:

This soup was really good! I left out the onion because I can't
have them and it's still really flavorful!
So glad you like it Stephanie! The pesto gives lots of flavour without the onion I think 🙂
This looks delicious! If I've got homemade pumpkin puree on hand, how much would I need instead of the recipe's diced pumpkin?
I haven't tried it myself with pumpkin puree, but would estimate around 4 cups. If you want more a 'pumpkin' flavour then perhaps another cup or two. Hope you enjoy!
