Fall is here, and of course that means it’s time to have some fun with everyone’s favorite seasonal gourd: pumpkin.

Don’t get me wrong, I have nothing wrong with pumpkin. It’s just that sometimes pumpkin can taste a little like…nothing.

That’s why I like to pair it with some big time flavor friends. In the case of this soup recipe, I’ve called on miso, chilis, and oyster mushrooms.

The result is a creamy, spicy, and umami-rich soup that will definitely warm you up in more ways than one.

Miso Pumpkin Soup Ingredients

For this recipe you’ll need:

  • Sugar pumpkin: also known as pie pumpkin. You’ll need a smaller one that’s around 2-2.5 pounds
  • Onion
  • Garlic: aim for a head of garlic that’s on the small side.
  • Carrots
  • Oyster mushrooms: any variety of oyster, foraged or farmed, work great in this soup
  • Vegetable stock
  • Coconut milk
  • White miso paste
  • Coconut Aminos
  • Thai Chilis: I love throwing some serious heat at this soup, so I opt for two chilis. For milder soup, just go with one. You can substitute with 1/4 teaspoon of red chili flakes.
  • Green onions
  • Extra Virgin Olive Oil
  • Sesame Oil

How to Make Miso Pumpkin Soup with Oyster Mushrooms

Start by cutting the pumpkin in half width-wise, or around the equator if you will.

Scoop out the seeds with a spoon (save them for roasting), then rub a little olive oil over the inside of the pumpkins and season with sea salt and black pepper.

Scrub the carrots and also cut the onion and garlic clove in half, leaving the skins on.

Line a baking sheet with a mat or parchment paper. Place the garlic cloves cut side down on the sheet, then place the pumpkin halves on top of each garlic half.

Housing the garlic inside the pumpkin is a neat little trick I devised. It not only prevents the garlic from burning, but it also allows the aromatics of the garlic to completely permeate through the pumpkin, resulting in some wonderful garlicky roasted flesh.

Nestle the carrots on the sheet, then drizzle a little olive oil on top of all the vegetables.

Transfer the baking sheet to a preheat 400°F oven and roast for about 50-60 minutes until the pumpkin is extremely tender.

You should be able to pierce it all the way through with a knife with zero resistance.

When the pumpkin is tender, remove it from the oven and allow it to slightly cool. Roughly chop the pumpkin into large chunks, discarding the stem, and transfer it to a high speed blender.

Note eating pumpkin skin: Yes, you can totally eat the skin of a sugar pumpkin! If you are using a true high-speed blender, the skin will just dissolve into the puree as you blitz it. If you are using a standard blender though, I do recommend peeling off the skin before blending to avoid finding unsightly bits of skin in the soup.

Roughly chop the onion and carrots and add them to the blender, and squeeze out the garlic cloves from their skin into the blender.

Select the “soup” setting on your blender if there is one, or simply blitz on high speed for 3-4 minutes until everything is smooth and creamy.

While the pumpkin is roasting, slice the green onion and chilis, and chop or tear the oyster mushrooms into even, bite-size pieces.

Heat two tablespoons of olive oil in a large skillet over medium heat, then add the mushrooms in an even layer.

Cook the mushrooms, undisturbed for about 5 minutes until they have released their liquid and start to brown, then give them a stir and cook for another 4-5 minutes until they are nice and browned all over.

Season the mushrooms with a pinch of salt, then add the green onion, chili, and sesame oil.

Continue cooking for another 2-3 minutes until the onion is soft and the mushrooms are very brown and almost crispy, then remove the skillet from heat.

Delightful Umami flavor, never had pumpkin soup like this! Restaurant and guest worthy. I substituted dried chanterelle mushrooms that I reconstituted in red wine and olive oil for the blue oyster mushrooms. The pumpkin I had was super watery, so when I baked it in the oven there was lots of water in the sheet pan. Substituted red pepper flakes for the chilis and added a bit of butternut squash to the mix. Truly delightful! Try this!!!
