Author Notes

Creamy vegetable soups without cream (or milk!) are possible. The base formula of fat + vegetable + liquid yields an incredibly smooth and luscious consistency once blended, after being cooked until the flavors meld in a good, heavy-duty soup pot—like All-Clad’s FUSIONTEC™ 4-Quart Soup Pot. Here, potato adds extra body to a classic cream of celery soup that’s amped up a bit by the addition of brown butter. A final swirl of pesto at the end brings another layer of flavor. You can use any type of potato, but Yukon Gold is particularly great here as it adds a nice richness. —Posie (Harwood) Brien

What You'll Need
Ingredients
  • 4 tablespoons unsalted butter
  • 3 pounds (about 20 stalks) celery, chopped
  • 2 medium potatoes, peeled and diced
  • 1/2 teaspoon kosher salt, plus more to taste
  • 5 cups chicken stock
  • 1/2 cup pesto
Directions
  1. In a large Dutch oven or heavy-bottomed soup pot, add the butter.
  2. Cook the butter over medium-high heat, swirling the pan occasionally, until the butter begins to brown. First it will foam up, then the foam will subside and the solids at the bottom will begin to take on color. Watch for flecks of amber that begin to darken; this will take about 5 minutes. Stop just before the butter turns deep golden-brown—you want it a little more pale than usual, since you’re going to carry on cooking.
  3. Turn the heat down to medium, add the celery and potato, and season with salt. Cook, stirring occasionally, for about 8 minutes or until the celery begins to soften.
  4. Add the chicken stock; simmer for about 20 minutes.
  5. Use an immersion blender to blend the soup to a creamy texture. (You can also do this in a blender—just be careful transferring the hot liquids, and do it in batches.) Taste the soup and add salt as needed.
  6. Divide between bowls and swirl a generous spoonful of pesto into each bowl. Serve warm.

My family and I enjoyed this soup! I used BTB no-chicken base, added a good bit of black pepper, and finished with a tablespoon of sherry vinegar in the pot, because I didn't have pesto. When I make it again I will probably sautee some onion/garlic before adding the celery and potato, but it was really cool to see what these two veggies could do on their own. Yum, off to have another big helping :)
