Roasted Pumpkin Bisque is made with a fresh sugar pie pumpkin. It’s served with an (optional, but delicious) mushroom gruyere crostini.

This recipe was originally created when I entered it into a recipe contest many years ago. The challenge was to come up with a recipe using Pacific Natural Foods broth and mushrooms. You can use any brand of broth, of course, but Pacific Natural Foods makes a mushroom broth, and that is what this recipe calls for. You are welcome to substitute vegetable or chicken broth, if you cannot find the mushroom broth.

I have a recipe for Pumpkin Soup with Gruyere that is quite fantastic, so I used that recipe as the inspiration to make this one.

PREPARE THE ROASTED PUMPKIN:

  • Preheat oven to 425°F. Spray a baking sheet lightly with nonstick spray.
  • In a medium bowl, toss the pumpkin with butter, thyme, sea salt and pepper. Spread on the baking sheet; bake for 20 minutes, or just until tender.  Remove from the oven, and reduce the oven to 400°, so it’s ready for preparing the crostini.

PREPARE THE SOUP:

  • In a medium saucepan, heat the olive oil to medium-heat. Add the onion; sauté until the onion is tender and beginning to brown lightly at the edges (about 5 minutes). Add in the thyme, broth, wine, cider, cardamom, ginger, cayenne, salt and pepper. Scoop the roasted squash into the broth; bring to a boil. Reduce the heat and simmer for 10 minutes. Remove from heat.
  • Pour the soup mixture into a food processor and process until smooth and creamy. Return to the pan. Add the cream, stir and keep on low heat.

I didn’t take home a prize for this from this recipe contest, but this soup recipe remains a favorite in our house. So that’s a win!

It turns out to be so creamy and delicious. The roasted pumpkin lends a yummy, earthy flavor to the soup. Combined with all of the spices, mushroom broth and a little sweetness from the apple juice… it all really works wonderfully.

How to make Mushroom Gruyere Crostini:

This part of the recipe is completely optional, but I highly suggest you make the crostini for dunking in the soup. It’s an amazing combination!

Place the bread slices on a baking sheet. Put in the oven for 3 to 4 minutes, just until lightly toasted. Remove from the oven.
 
In a large skillet, heat the olive oil at medium heat. Add the garlic and mushrooms. Sauté until the garlic is fragrant and the mushrooms are no longer dry.
 
Divide the mushrooms between the toasts, piling them on top. Sprinkle with Gruyere cheese. Place the toasts back into the oven until the cheese is melted, about 3 to 4 minutes. Dunking mushroom gruyere crostini into the roasted pumpkin bisque is highly encouraged. Enjoy!

  4. Marnie says:

    Mmmm You got my vote! This sounds so yummy! Now if I can just find a sugar pie pumpkin..

    1. Lori Lange says:

      @Marnie, They should have them at your regular market. They’re the only pumpkins that you should be using to cook with– usually labeled as “pie pumpkins” or “sugar pumpkins.” You’ve probably seen them before & just not noticed what they were called. Look for pumpkins that are about the size of a baby’s head!

  5. Barbara says:

    Ummmm, Lori? Can you just pass me some of the mushroom crostini and I’ll try the soup later?

  6. Heather (Heather's Dish) says:

    that crostini with mushrooms looks amazing – what a great combination of textures, flavors, and colors!

  7. Tracy says:

    This looks amazing! I’m pretty sure I could eat this for the entire fall season and not get tired of it. 🙂
