Preheat your oven to 400°F (200°C). Spread the cubed butternut squash and sliced carrots evenly on a baking sheet. Drizzle with olive oil and toss to coat.
Roast the vegetables in the oven for about 25-30 minutes, or until they are golden brown and tender when pierced with a fork.
Remove the roasted vegetables from the oven and allow them to cool slightly for a few minutes.
Add the roasted vegetables, grated ginger, and vegetable broth to a large pot. Bring the mixture to a gentle simmer over medium heat.
Ladle the hot mixture into a blender or use an immersion blender to blend until mostly smooth, leaving some chunks for texture if desired.
Return the blended soup to the pot and heat gently. Season with salt and pepper to taste. Adjust the consistency with additional broth if needed.
Ladle the hot soup into bowls, allowing some chunks of roasted vegetables to remain visible for texture and visual appeal.
Enjoy your warm, vibrant bowl of roasted butternut squash and carrot soup topped with a sprinkle of fresh herbs or a drizzle of olive oil if desired.
