Squash Soup with Nutmeg and Walnut Oil

47 Comments

I’m actually not a soup person, no matter what time of year it is. But I was highly intrigued by this recipe in Eric Ripert’s cookbook, A Return to Cooking. Interestingly enough, the other recipe I’ve blogged about from the same cookbook was an outstanding seafood chowder.


Chef Ripert’s name for this soup is Pumpkin, Acorn, and Butternut Squash Soup with Nutmeg and Walnut Oil. I like the idea of mixing the squashes, and then nutmeg and walnut oil as finishing touches?! Yes please.

Here is the cookbook, published in 2009.

From the author, Michael Ruhlman, regarding this recipe: “Eric almost didn’t make this soup because he’s so put off by overspiced squash soups. While he does add some gratings of fresh nutmeg at the end, the fresh thyme and the walnut oil are the primary seasonings, and the soup retains the flavors of the squash.”

Pumpkin, Acorn, and Butternut Squash Soup with Nutmeg and Walnut Oil
Printable recipe below

6 tablespoons unsalted butter
1 cup sliced onions
2 cups peeled and diced sugar pumpkin
2 cups peeled and diced acorn squash
2 cups peeled and diced butternut squash
Fine sea salt
Freshly ground white pepper
5 cups chicken stock
1 cup heavy cream
3 thyme sprigs
3 ounces sharp cheddar cheese
1 tablespoon walnut oil
1 whole nutmeg, for grating

Melt 2 tablespoons of the butter in a large pot over medium heat. Add the onions and cook until translucent, about 3 minutes. Add the pumpkin, acorn and butternut squash dice and sauté until softened, about 10 minutes. Season with salt and pepper to taste.

Cover with the chicken stock and bring to a simmer. Cook until the squash is tender, about 30 minutes.

Purée the soup in batches in a blender until satiny-smooth. Pass through a fine-mesh sieve to remove any remaining lumps, and return the soup to the pot. Add the cream and the remaining 4 tablespoons of butter. Bring to a simmer.

Wrap the thyme sprigs in a square of cheesecloth and tie with kitchen string. Add to the simmering soup and let infuse for 10 minutes. Remove the thyme bundle and adjust the seasoning.

To serve, divide the soup among six warmed soup bowls. Shave the cheese over each bowl and drizzle the walnut oil over the cheese.

Grate nutmeg over each bowl to taste and serve immediately.

The walnut oil I purchased in August of 2021 and opened in October to make this recipe was rancid. The bottle was sealed, so I was surprised and disappointed. I don’t recommend this brand.
