Step 1: Prep and Roast the Pumpkin
Preheat your oven to 180°C (350°F). Line a large baking sheet with parchment paper or aluminum foil.
Cut the pumpkin in half and scoop out the seeds and stringy pulp with a spoon.
Carefully peel the tough outer skin using a sharp chef's knife, then cut the pumpkin flesh into 2-inch cubes.
Place the pumpkin cubes on the prepared baking sheet. Drizzle with 1 tablespoon olive oil and season generously with salt and pepper.
Toss to coat evenly, then spread in a single layer (don't overcrowd).
Roast in the preheated oven for 25-30 minutes, turning once halfway through, until the pumpkin is fork-tender and slightly caramelized at the edges.
Remove from oven and set aside.
Step 2: Sauté Aromatics and Ginger
While the pumpkin is roasting, heat 2 tablespoons olive oil in a large pot or Dutch oven over medium heat.
Once the oil is shimmering, add the diced onion and cook for 3-4 minutes, stirring occasionally, until translucent and softened.
Add the minced garlic and fresh ginger to the pot, stirring constantly for 1-2 minutes until very fragrant.
Important: Don't let the garlic or ginger brown or burn, as this will make them bitter.
Step 3: Simmer and Blend
Add the roasted pumpkin cubes to the pot with the sautéed aromatics.
Pour in the vegetable broth, enough to just cover the pumpkin pieces.
Bring the mixture to a boil over high heat, then immediately reduce the heat to low.
Simmer gently for 10 minutes to allow the flavors to meld together.
Remove the pot from the heat.
Using an immersion blender, blend the soup directly in the pot until completely smooth and creamy.
Alternative: Carefully transfer the soup in batches to a regular blender and blend until smooth. Hold the lid down firmly with a kitchen towel to prevent hot soup from splattering.
Step 4: Finish with Coconut Milk and Season
Stir in the full-fat coconut milk until fully incorporated and the soup has a uniform creamy orange color.
Place the pot back on the stove over low heat and warm the soup through for 2-3 minutes. Do not boil after adding coconut milk, as it may separate.
If using optional spices (cumin, coriander, turmeric), add them now and stir well.
Season with salt and freshly ground black pepper to taste. Remember that flavors become more muted as soup cools, so it should taste slightly overseasoned when hot.
Add fresh lime juice or apple cider vinegar if desired, to brighten the flavors.
If the soup is too thick, thin it with additional vegetable broth or water until you reach your desired consistency.
Taste and adjust seasoning one final time before serving.
