Roasting the squash instead of boiling it drives off water and caramelizes the sugars, which is the whole difference between a flat soup and a deep one. Cut the squash flesh-side down on the sheet pan so it steams into its own concentrated puree.

Butternut squash
The backbone; a firm heavy squash with matte skin roasts to a dense caramelized puree.
Roast the squashHalve, seed, and roast at 425F flesh-side down for 40-45 minutes until a knife slides through and the edges brown. Scoop the flesh out of the skin.
Build the baseSweat the diced onion in butter over medium heat 8 minutes until translucent, then add the roasted garlic and a pinch of nutmeg and sage.
SimmerAdd the squash and broth, bring to a simmer, and cook 15 minutes to marry the flavors.
Blend and finishPuree until completely smooth, stir in the cream, and season with salt until the sweetness snaps into focus.
Can you make Butternut Squash Soup in an air fryer? — Yes, with an insert
Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.
Can you freeze Butternut Squash Soup? — Yes
Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.
Can you make Butternut Squash Soup ahead of time? — Yes
Yes — it holds well and often tastes better the next day. Make it ahead and reheat gently before serving.
Is Butternut Squash Soup gluten-free? — Yes
Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.
Is Butternut Squash Soup vegan? — No
No — it contains meat, so it isn’t vegetarian or vegan.
