Fall whispers into my kitchen with this sweet potato and parsnip soup that warms my soul. I whipped up this dish one rainy evening while hunting for the perfect comfort food. The blend of earthy sweetness topped with golden mushrooms and crunchy walnuts turns dinner into a moment of pure delight.
Soothing soul-warming soup
What gets me every time about this soup is its natural sweetness boosted by whatever herbs I've got growing - sometimes sage, other times thyme, depending on my mood. Those crispy golden mushrooms bring their woody flavor while a drizzle of olive oil adds that Mediterranean touch. It's basically a hug in a bowl that makes everything better.

Kitchen magic begins
- Getting everything ready
- First I peel and chop my veggies, then slice that onion super thin to join the party.
- Creating flavor foundations
- In my favorite pot, I heat oil gently until my veggies turn a pretty golden color.
- Blending the flavors
- I toss in herbs and broth, letting everything simmer with the lid on, then off - that's when the real magic happens.
- Mushroom spotlight
- Meanwhile, I sauté my mushrooms with garlic and sage until they're perfectly golden and crispy.
- Bringing it all together
- I blend the soup until smooth, pour it into bowls, top with mushrooms and walnuts, add a splash of olive oil, and it's done.

Storage tips and tricks
The soup stays good in the fridge for a couple days no problem. I like making the mushrooms fresh when serving, but they'll keep for a few hours too. For busy days, I freeze single portions in airtight containers after they've cooled down. It's like having a little comfort stash ready to warm up those cold winter evenings.
