This soup is an absolute showstopper! The aroma that fills your kitchen is just the beginning—you'll be amazed by the earthy, comforting flavours in each spoonful. And let's talk about the colours: vibrant yellow from the squash, warm orange from the carrots, and the subtle green and brown tones from toasted pistachios. This is autumn comfort in a bowl. 🍁

Like most of my soup recipes, there's no need for cream here. You can skip it altogether, use a small splash for a touch of richness, or go all out if that's your preference. I like to add just a hint, enhancing the soup's texture without overpowering the natural sweetness of the squash or adding unnecessary calories.

Maple syrup is completely optional but highly recommended. It adds a subtle sweetness and depth of flavour that complements the roasted squash beautifully. Speaking of roasting—rather than halving and roasting the squash, I chop it into smaller pieces and roast them. This technique brings out a sweeter, more caramelized flavour that makes the soup even more delicious and complex. 🍂✨

Ingredients

Servings:

1 butternut squash (2 to 2 1/2 lbs), peeled and chopped into 1/2 to 3/4 inch cubes as evenly as possible
1 large or 2 medium carrots, peeled and chopped into 1 inch chunks
1 tbsp olive oil
kosher salt
2 tbsp butter
1 small to medium yellow onion
2 stalks of celery, chopped
¼ tsp dried thyme leaves
1 bay leaf
3 to 4 cups of chicken or vegetable stock
1 tsp maple syrup, plus more to taste
3 tbsp heavy cream, plus more to taste
¼ cup toasted shelled pistachios or other nuts of choice
freshly ground black pepper

Instructions

1
Preheat the oven to 400°F (200°C). Peel the butternut squash and dice it into 1/2 inch (1.25cm) cubes; chop the carrots into 1 inch (2.5cm) chunks. Dry them well with paper towels (this will help them caramelize better) and drizzle with a little olive oil and some kosher salt, then scatter onto a rimmed aluminium baking sheet (do not use parchment, or it won't brown). Bake in the preheated oven. It will take around 40–45 minutes (may take longer if you chopped it into larger chunks). It should be very tender when tested with a fork, golden brown and caramelized on the outside. After 30 minutes of cooking, flip each squash and carrot chunk to caramelize the other side. Remove from the oven when ready.
2
While the squash bakes, let's make the base of the soup. Heat the butter over medium heat in a large pot, swirling the pan constantly and stirring the butter with a wooden spoon. At first your butter will shimmer (the sound of water evaporating), then it will start to brown and you will see brown solids forming; your butter will become perfectly still and smell nutty—you've just made brown butter. This whole process should take only about 1.5–2 minutes for this small amount of butter. Be sure to watch closely, stir constantly to avoid burning and scorching the pot.
3
As soon as your brown butter is ready, add the onions and celery and cook for about 5 minutes until soft and translucent, but not browned. Proceed to the next step immediately, or remove from heat and set aside until your squash and carrots are ready.
4
Add your squash and carrots to the pot with the onions and celery. Add the thyme, bay leaf, and about 3½ cups (840ml) of stock and bring to a simmer. Reduce the heat to maintain a steady simmer and cook for about 10–15 minutes for the flavours to meld and for the onions and celery to become very tender.
5
Remove the bay leaf and transfer the contents of the pot to a blender (or use a handheld immersion blender). Process until very creamy and smooth. If needed, add the remaining ½ cup (120ml) stock to thin the soup to your desired consistency. Stir in the optional cream and maple syrup. Taste your soup and season with more salt and pepper.
6
Divide the soup into 6 servings, garnish with nuts and freshly ground black pepper. Enjoy.

FAQ

Can I make butternut squash soup ahead of time?+

Yes! This soup keeps for up to 4 days in the fridge or freezes beautifully for 3 months—just store it before adding the brown butter and cream, then warm it gently and stir those in when you're ready to serve.

What can I substitute for heavy cream in this butternut squash soup?+

You can use coconut milk, Greek yogurt, or cashew cream for a similar creamy texture; just stir them in at the end and adjust the amount to your preferred richness since alternatives vary in thickness.

Why isn't my butternut squash roasting evenly?+

Make sure you're cutting your squash into consistently-sized 1/2 to 3/4 inch cubes and patting them dry before roasting—uneven pieces and excess moisture are the main reasons some pieces brown while others stay pale.

How do you make brown butter and when do you add it to the soup?+

Melt the 2 tbsp butter in a small pan over medium heat, swirling occasionally until the milk solids turn golden brown (about 5-7 minutes), then drizzle it into individual bowls of soup just before serving for maximum nutty flavor.
