Ingredients
  

For the Roasted Vegetables
  • 5 cups butternut squash peeled and diced, from about 1 small squash
  • 2 cups carrots peeled and sliced into 1-inch pieces
  • 1/2 medium white or yellow onion sliced, about 1 cup
  • 5 whole garlic cloves peeled, can be gently smashed
  • 2 tsp avocado oil or substitute maple syrup or extra vegetable broth for oil-free
  • 2 tsp maple syrup
  • sea salt and black pepper to taste
For the Soup
  • 1 1/2 to 2 cups vegetable broth
  • 2/3 cup light coconut milk plus extra for garnish if desired, or use cashew milk
  • 1/4 tsp ground cinnamon
  • 1 pinch nutmeg optional
  • 1 pinch cayenne pepper optional
For Garnish
  • toasted croutons
  • toasted pepitas (pumpkin seeds)

Equipment

  • Two baking sheets
  • Parchment paper
  • Large pot or Dutch oven
  • Immersion blender or high-speed countertop blender

Method
 

  1. Set your oven to 400°F (204°C) and prepare two baking sheets by lining them with parchment paper. Distribute the diced squash, carrot slices, onion pieces, and whole garlic cloves evenly across both sheets, making sure they form a single layer. Coat the vegetables with the avocado oil and maple syrup, then season liberally with salt and pepper. Toss everything together until all pieces are well covered. Place the sheets in the oven and roast for 25–30 minutes, until the squash and carrots can be easily pierced with a fork and show golden caramelized spots.
  2. Move all the roasted vegetables from the baking sheets into a large pot or Dutch oven. Add 1½ cups of vegetable broth along with the coconut milk, cinnamon, and optional nutmeg and cayenne. Stir everything together and heat over medium until it begins to simmer gently. Lower the heat, cover the pot with a lid, and let it cook undisturbed for 5–10 minutes so the flavors can meld.
  3. Blend the soup until it reaches a completely smooth, velvety texture. You can use an immersion blender right in the pot, or carefully ladle the hot mixture into a countertop blender (working in batches if necessary for safety). If the soup seems too thick after blending, gradually stir in more vegetable broth until you achieve the consistency you prefer.
  4. Sample the soup and make any final seasoning tweaks. Add extra salt, pepper, maple syrup, or any of the spices (cinnamon, nutmeg, cayenne) to adjust the flavor balance to your taste.
  5. Divide the hot soup among serving bowls. Top each portion with a drizzle of coconut milk if you like, and finish with a sprinkle of toasted pepitas or croutons for added texture and visual appeal. Serve right away.

Notes

To make this soup oil-free, replace the avocado oil with a splash of extra vegetable broth or a touch more maple syrup before roasting. Cashew milk, oat milk, or soy milk can all stand in for the light coconut milk if needed, though coconut milk gives the richest, silkiest result. For the smoothest texture, blend the soup for at least a full minute and consider using a high-speed countertop blender rather than an immersion blender. Store leftovers in an airtight container in the refrigerator for up to 4–5 days — the flavors deepen beautifully overnight. To freeze, cool the soup completely and transfer to airtight freezer-safe containers for up to 1 month; thaw overnight in the fridge and reheat gently on the stovetop over low heat, adding a splash of broth or coconut milk to loosen if needed.
