Roasted Winter Squash and Feta Soup
This Roasted Winter Squash and Feta Soup is a cozy, crowd-pleasing appetizer soup that will start your holiday feasts on a festive note. Inspired by the viral baked feta trend, this recipe takes the winter squash of your choice, roasts it with onions, garlic, and a block of feta cheese for a deep, caramelized flavor, then blends it all into a luscious, velvety soup. Far from boring, this gourmet soup includes a touch of fun with croissant slices topped with fried prosciutto and cheese, with a crunch that perfectly complements the silky soup.

Why I Love This Soup, and Hope You Will, Too
With the holidays coming up, I always feel compelled to serve soup, even though it’s often not thought of as a traditional fancy-pants menu item. This soup takes care of that!
Roasted Winter Squash and Feta Soup makes a lovely starter dish, as it’s creamy and decadent and quite unique. Because it’s an appetizer soup, don’t serve it in a huge bowl as though it’s a meal. You don’t want your guests to fill up before the main course!
Plus, the soup is very rich, and just a small bowl is the right amount to get the full enjoyment of the complex flavors. It’s make-ahead easy, so whip it up a day or two before your big event and stash it in the fridge.

Main Ingredients and Substitutions
Winter squash — This soup is wonderfully flexible in that it can use just about any of the winter squashes, from butternut to pumpkin to kabocha, and more. I used pumpkin, plus a delicious honeynut from my garden. Butternut squash is readily available in U.S. grocery stores, both fresh and frozen. Frozen is absolutely fine; just be sure to thaw it before making the soup.
Feta cheese — Choose the best feta that you’re willing to spring for. Don’t use crumbled feta; it will not turn out the way you expect.
Aromatics — Roasted onions and garlic add another layer of flavor to the soup, especially roasted garlic, which tames down into something mild and sweet.
Herbs — This autumn soup is seasoned beautifully with thyme, rosemary, and sage.
Cook’s Notes
- You have a couple of blending options: a regular or high-speed blender, or an immersion blender. I prefer the immersion route for easier clean-up.
- Fresh herbs are lovely but I don’t roast them in the oven; use dried herbs here.
- If you don’t want to fix the croissant croutons, chopped fried sage is a lovely topping.
- This soup holds well in the fridge for several days, perfect for make-ahead meals.
