Flavorful Butternut Squash Soup with Brown Butter, Veggies, Toasted Pistachios, and Optional Maple Syrup 🍂🥣

This soup is an absolute showstopper! The aroma that fills your kitchen is just the beginning—you’ll be amazed by the earthy, comforting flavors in each spoonful. And let’s talk about the colors: 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 flavor 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 flavor that makes the soup even more delicious and complex. 🍂✨

FLAVOURFUL BUTTERNUT SQUASH SOUP

Yields1 Serving
Cook Time1 hr

 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

1

Preheat oven to 400°F.

Peel the butternut squash and dice into 1/2 inch cubes; chop carrots into 1 inch chunks. Dry them well with paper towel (will help them caramelize better) and drizzle with a little bit of olive oil, some kosher salt and scatter onto a rimmed aluminum baking sheet (do not use Parchment or it won't brown.)

Bake in 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 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 (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 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 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 onions and celery. Add thyme, bay leaf and about 3 1/2 cups of stock and bring to simmer. Reduce to maintain steady simmer and simmer for about 10-15 minutes for flavours to meld and for onions and celery to become very tender.

5

Remove the bay leaf and transfer the contents of the pot to a blender (or use handheld immersion blender.) Process until very creamy and smooth. If needed, add remaining 1/2 cup stock to thin the soup out to desired consistency.

Stir in optional cream and maple syrup. Taste your soup and season with more salt and pepper, to taste.

6

Divide between two bowls, garnish with nuts and freshly ground black pepper. Enjoy.
