Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 3 lbs peeled and cubed butternut pumpkin with 2 tbsp olive oil and 1/2 tsp salt on a rimmed baking sheet. Roast for 30-35 minutes until tender and caramelized at the edges.
  2. Step 2: While pumpkin roasts, heat 1 tbsp olive oil in a large pot over medium heat. Add 1 large chopped yellow onion and sauté for 6-7 minutes until softened and translucent.
  3. Step 3: Add 3 minced garlic cloves and 2 tsp ground wattleseed, cooking for 1 minute until fragrant. Stir in the roasted pumpkin and 4 cups vegetable stock.
  4. Step 4: Bring the soup to a simmer, add 1 tsp fresh thyme leaves, 1 tsp salt, and 1/2 tsp black pepper. Simmer gently for 10 minutes to meld flavors.
  5. Step 5: Meanwhile, toast 1/4 cup pepitas in a dry skillet over medium heat, shaking frequently for 3-4 minutes until golden and fragrant.
  6. Step 6: Use an immersion blender to puree the soup until smooth and creamy. Adjust seasoning if needed.
  7. Step 7: Serve the soup hot with a dollop of 1/2 cup plain Greek yogurt and sprinkle with toasted pepitas for a delightful contrast.
