Heat the butter and olive oil in a large, heavy-bottomed pot over medium heat. Add the onion and cook for 6-8 minutes, stirring often, until very soft and lightly golden.
Add the minced garlic and grated ginger. Warm briefly, about 30-45 seconds, until fragrant.
Add the cubed butternut squash, broth, thyme, and bay leaf. Bring to a boil, then reduce to a gentle simmer. Cover and cook for 20-25 minutes, until the squash is completely tender when pierced.
Remove the thyme sprigs and bay leaf. Blend the soup until perfectly smooth using an immersion or countertop blender.
Stir in the heavy cream (if using), salt, and black pepper. Warm gently over low heat without boiling. Garnish with your favorite topping or one of my go-to options shared earlier in the post.
Notes
Don’t rush onion caramelization. Properly softening and lightly caramelizing the onion builds the base flavor of the soup.
Keep the simmer gentle. A steady simmer, not a hard boil, helps the squash soften evenly and prevents the soup from turning grainy once blended.
Make sure the squash is fully tender before blending. If it still feels firm when pierced, give it a few more minutes. Fully tender squash is key to a smooth, velvety texture.
Blend a little longer than you think. An extra minute of blending helps achieve a silkier finish.
Adjust the thickness at the end. If the soup thickens after blending or reheating, just add a small splash of broth or water until it reaches the texture you like.
Taste at the finish. Taste at the finish. Salt and pepper are best adjusted at the very end, especially if you’re using a salted broth or skipping the cream.
