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.

Shopping list for heavenly soup

  • Sweet potatoes: 2 good ones chopped into small cubes for ultimate smoothness
  • Parsnips: 4 medium ones cut into slightly bigger chunks
  • Onion: Just one will do, thinly sliced
  • Mushrooms: 400g of small brown ones, nice and fresh
  • Garlic clove: One fat one to flavor those mushrooms

  • Fresh herbs: Grab sage or thym, whatever you fancy
  • Salt and pepper: Freshly ground, of course

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.

Frequently Asked Questions

→ How should I store this soup?
Keep the soup in the fridge for up to two days without toppings. Once cooled, it can also be frozen in a plastic bottle or airtight container.
→ Can the toppings be prepped early?
Sautéed mushrooms hold well at room temperature for a few hours, but they're best served hot. Prepare nuts and herbs just before serving.
→ What’s the trick to the perfect texture?
Adjust the thickness with more or less water while blending. For an ultra-smooth soup, blend longer on high speed.
→ Can I swap fresh herbs?
Sage and thyme can replace each other based on your taste. Dried herbs work too; use smaller amounts.
→ What’s the best way to clean mushrooms?
Rinse mushrooms briefly under running water, then pat them dry. Don’t soak them as they’ll absorb too much water. Trim off the earthy stem bottoms.
