Ingredients needed
The ingredients for this roasted butternut squash soup recipe are listed fully down in the recipe card but let’s briefly go over the pantry staples needed including a few substitutions you can make as desired!
Butternut squash 1 Roasting it halved (instead of cubed) keeps this easy and develops incredible caramelized flavor.
Yellow onion – Adds savory depth and balances the squash’s natural sweetness.
Garlic cloves – Essential for a rich, aromatic base.
Vegetable broth – Thins the soup and keeps it vegetarian. You can sub for vegetable stock or even chicken broth if preferred.
Ground cumin – Adds subtle warmth and complexity without overpowering the squash.
Nutmeg (optional) – Just a pinch enhances the natural sweetness and gives that classic fall soup vibe.
Milk – Makes the soup extra creamy. Whole milk gives the richest texture, but you can use 2%, half and half, heavy cream, or unsweetened plant milk if needed. I’ve also made this with sour cream instead of milk and LOVE the little bit of tang that it adds to the soup.
Optional toppings – Pumpkin seeds, fresh thyme, crispy sage leaves, cracked black pepper, or a drizzle of cream or olive oil for a beautiful finish. This is also delicious served with a good slice of crusty bread!
How to Make It
Just a reminder that you can find the FULL written recipe down in the recipe card, but I want to quickly go over how to make them with visuals for you 🙂
Cut the squash in half and remove the seeds. Place on a rimmed baking sheet and rub the flesh side with olive oil and season generously with salt and pepper. Roast until fork tender, about 45 minutes.
Meanwhile, saute the onion and garlic in a large pot over medium-high heat.
Once the squash is done, carefully remove the flesh using a large spoon and put it into the pot with the onions along with the veggie broth, cumin, and nutmeg. Simmer for about 5 minutes.
Using a blender or immersion blender, carefully blend the soup until it’s silky smooth. I find it easiest to get a creamy texture in a high-powered blender but I also love the ease of an immersion blender. Stir in the milk and season to taste.
Expert Tips for the Best Roasted Butternut Squash Soup
Roast cut-side down on the sheet pan. This traps steam and caramelizes the edges for a deeper flavor!
Blend thoroughly. A full minute of blending makes the soup ultra smooth and silky. While a high regular blender gets the soup silkier smooth, I usually prefer the ease of an immersion blender (which still does a great job!).
Adjust thickness last. Add extra broth after blending to control consistency. I don’t usually need any but it’s an option if you like your soup thinner.
Taste before serving. Butternut squash varies in sweetness—sometimes it needs an extra pinch of salt.
