Hannah Storm's Mystery Soup

The “mystery” in this soup is pumpkin, and it works brilliantly. A full pound of sliced mushrooms gets sauteed in butter with onion, then simmered in chicken broth alongside pumpkin puree until everything melds into a velvety, earthy base.

Half-and-half stirred in at the end gives it body without making it heavy, and the honey and nutmeg push it into cozy fall territory. The honey isn’t just sweetness here. It rounds out the earthy pumpkin and mushroom flavors so neither one dominates.

The flour goes in right after the saute, before any liquid. This is your roux, and it’s what keeps the soup thick and silky instead of thin and watery. Give it a minute to cook out the raw flour taste before adding the broth.

Chef Tips

• Use canned pure pumpkin puree (not pumpkin pie filling, which has sugar and spices already added).
• Slice mushrooms evenly, about ¼ inch thick, so they cook at the same rate.
• For a smoother soup, blend half the batch with an immersion blender and stir it back in. You keep some texture but lose the chunkiness.
• Freshly grated nutmeg makes a noticeable difference over pre-ground.

Variations

• Swap pumpkin for butternut squash puree for a slightly sweeter, nuttier flavor.
• Add a pinch of cayenne or smoked paprika for warmth.
• Top with toasted pumpkin seeds instead of croutons for a seasonal crunch.
