What You Need to Make Butternut Squash Soup

Broth or water and olive oil. To blend the butternut squash soup and roast the vegetables.
How to Make Red Curry Butternut Squash Soup
Here is the quick walk-through, and the full recipe is in the card above.
Wrap and roast. Place the squash, onion, and garlic on foil, drizzle with olive oil, salt, and pepper, wrap, and bake 1 hour at 400 degrees F.
Scoop. Cut off the ends, halve the squash, scoop out the seeds, and add the flesh to a blender.
Blend. Add the broth and red curry paste and blend until smooth.
Simmer. Pour into a pot, bring to a boil, add the coconut milk, and simmer 5 to 10 minutes.
Serve. Ladle into bowls and serve with garlic bread or grilled cheese croutons.
Do You Have to Peel the Squash?
Good news: you do not have to peel the butternut squash for this butternut squash soup. Because everything gets blended until completely smooth, you can leave the skin on after roasting, which saves time and adds a little extra fiber and nutrients. Roasting softens the skin so much that it blends right in without any noticeable texture. That said, if you prefer a slightly lighter color and the silkiest possible result, the roasted skin peels off easily once the squash has cooled a bit. Either way works, so do whatever is easiest for you.
Tips for the Best Butternut Squash Soup
Roast until very tender. A fully soft squash blends into the creamiest butternut squash soup.
Start with less curry paste. Use 1 tablespoon, then add more to taste.
Blend well. Blend until completely smooth for that velvety texture.
Adjust the consistency. Add more broth for a thinner soup or less for a thick one.
Taste and season. A pinch of salt or a squeeze of lime brightens everything.
How to Add Protein
This butternut squash soup is light and perfect as a starter, but it is easy to turn it into a more filling meal. My favorite way to add protein is to blend in a can of drained white beans, such as cannellini or great northern, right along with the squash. They disappear completely into the creamy base and add plant protein and fiber without changing the flavor. You could also stir in a scoop of red lentils while the butternut squash soup simmers, top each bowl with crispy chickpeas or shredded chicken, or serve it with a protein-rich side. It is honestly perfect the way it is, but these easy additions make it a satisfying main.
What to Serve With It
This butternut squash soup is begging to be served with something for dipping. Garlic bread or crunchy grilled cheese croutons are my favorite, and a crusty baguette or naan works beautifully too. For a dinner party, serve small bowls as a starter with a swirl of coconut milk and a sprinkle of fresh cilantro or chili flakes on top. A simple green salad rounds it out into a light meal, and a drizzle of chili oil adds a little heat for those who want it. It is as pretty as it is cozy.
Make Ahead and Storage
This butternut squash soup is perfect for making ahead, and the flavor only gets better as it sits. Store it in an airtight container in the fridge for up to 5 days, or freeze it for up to 3 months, which makes it a great meal-prep option. Let it cool completely before freezing, and leave a little room in the container as it will expand. To reheat, warm it gently on the stovetop or in the microwave, adding a splash of broth or water if it has thickened. If you froze it, thaw it overnight in the fridge for the best texture, then reheat and give it a good stir.
The Perfect Starter for a Dinner Party
If you are hosting, this red curry butternut squash soup is a showstopping way to begin the meal. It looks elegant ladled into small bowls with a swirl of coconut milk and a few fresh herbs, yet almost all of the work happens hands-off in the oven, so you are free to focus on the rest of your menu. Because it can be made entirely ahead and gently reheated, there is zero last-minute stress, and it holds beautifully on the stovetop while guests arrive. The warm, cozy flavor feels special and a little unexpected, and it pairs with almost any main course that follows. Serve it with those crunchy grilled cheese croutons for a fun, interactive touch, and watch it become the dish everyone asks about. It is proof that an impressive starter can also be genuinely simple to pull off.
