Ingredients for Butternut Squash Leek Soup
This is a simple soup with just a few ingredients. The simple ingredients really let the butternut squash flavor shine through. Plus this recipe is naturally gluten-free and dairy-free!
- Butternut Squash – I opt for a whole squash rather than precut. It really makes a difference in flavor and color. Precut butternut squash can yield a brownish looking soup (rather than bright orange) from my experience.
- Leeks – Add the perfect oniony flavor. You’ll just use the white and light green part. The darker green parts can be discarded or saved to make chicken stock.
- Olive Oil
- Chicken Stock – Adds a nice depth of flavor. You can also use vegetable broth or vegetable stock.
- Fresh Thyme
- Cayenne Pepper – I prefer cayenne pepper to black pepper in this soup. It adds a touch of heat while keeping the soup an even orange color.
- Bay Leaf
Tip: Using a whole butternut squash you cut up fresh yourself rather than precut butternut squash really takes this soup to the next level. Using pre-cut squash often results in a brownish, rather than bright orange, colored soup.
How to Cut Up Butternut Squash
1. Start by peeling the butternut squash.
2. Next cut off the top and button of the squash.
3. Then cut the squash right above where it starts to curve out.
4. Cut the top part in half long ways then chop into chunks.
5. Slice the bottom in half then scoop the seeds out.
6. Chop the bottom into chunks.
How to Make Butternut Squash Leek Soup
Once you have your squash ready it’s time to make the soup. The numbered photos here match up with the how-to steps below.
1. Place the cut butternut squash soup in a bowl and cover with plastic wrap. Microwave for 15 minutes.
2. Meanwhile, in a large dutch oven, sauté the leeks in a few tablespoons of olive oil over medium heat until softened.
3. Add the softened butternut squash to the leek mixture. Let it sit and brown (but not burn!) on the bottom until the squash starts to caramelize. Cook this way stirring occasionally for 10 minutes. This brings out the flavor of the squash.
4. Add the chicken stock and scrap all the brown bits off the bottom of the pan.
5. Add the spices and bring to a simmer. Simmer for 10 minutes.
6. Blend until smooth with an immersion blender or in a high-speed blender. Season the pureed soup with a pinch of salt.
This soup is delicious as a meal on it’s own served with kale cranberry salad and gluten-free rolls. It’s also the perfect compliment to a holiday meal! Check out my full collection of gluten-free holiday recipes here.
What is a good garnish for this soup?
Once you’ve pureed the soup to perfection it’s ready to serve. You can serve the soup on its own or topped with delicious garnishes like crumbled bacon, a drizzle of cream (or coconut milk) or roasted pumpkin seeds.
Can I freeze this?
Butternut squash soup freezes wonderfully. I recommend making a double batch if you can because it freezes so well. Cool the soup in the refrigerator before transferring it to a freezer container in airtight containers for longer storage. Frozen butternut squash leek soup can last for up to 6 months.
