Ingredients
  

  • 4 tablespoons unsalted butter
  • 1 large yellow onion, diced
  • 8-10 large garlic cloves 6 minced, 2-4 sliced thin
  • 1/4 cup all-purpose flour
  • 4 cups low-sodium chicken broth or vegetable broth
  • 2.5 lbs Yukon Gold potatoes, peeled and cut into 1-inch cubes
  • 2 sprigs fresh thyme or 1 teaspoon dried thyme
  • 1 bay leaf
  • 1 1/2 teaspoons kosher salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1 cup heavy cream or full-fat evaporated milk
  • 2 tablespoons neutral oil for frying garlic garnish
  • Optional garnishes: crispy fried sliced garlic, chopped chives, grated sharp cheddar cheese, crumbled cooked bacon

Equipment

  • Large Dutch oven or heavy-bottomed pot
  • Chef's knife
  • Cutting board
  • Measuring cups and spoons
  • Whisk
  • Immersion blender (or standing blender)
  • Small skillet
  • Wooden spoon or spatula
  • Ladle

Method
 

  1. Melt the butter in a large Dutch oven over medium heat. Add the diced onion and cook until soft and translucent, about 5-7 minutes.
  2. Add the 6 cloves of minced garlic and cook for 60 seconds until fragrant, being careful not to let it brown.
  3. Sprinkle the flour over the onion and garlic mixture. Cook, stirring constantly, for 2 minutes to form a roux.
  4. Gradually whisk in the broth until no lumps remain. Add the cubed potatoes, thyme sprigs, bay leaf, salt, and pepper.
  5. Bring the soup to a boil, then reduce heat to a simmer. Cover and cook for 20-25 minutes, or until the potatoes are fork-tender.
  6. While the soup simmers, prepare the crispy garlic garnish. Heat 2 tablespoons of neutral oil in a small skillet over medium-low heat. Add the thinly sliced garlic and cook, stirring frequently, until golden brown and crisp. Immediately transfer to a paper towel to drain.
  7. Once the potatoes are tender, remove and discard the bay leaf and thyme sprigs. Using an immersion blender, blend the soup in the pot until completely smooth. (If using a standing blender, blend in batches carefully).
  8. Reduce the heat to low. Slowly stir in the heavy cream. Warm the soup through gently—do not allow it to boil.
  9. Taste and adjust seasoning with additional salt and pepper if needed.
  10. Serve immediately, garnished with the crispy garlic slices and other desired toppings.

Notes

For the best texture, use an immersion blender and avoid over-blending, which can make the soup gluey. Always temper the dairy by adding it off the boil over low heat to prevent curdling. For a lighter version, use full-fat evaporated milk. Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently on the stovetop. The soup can be frozen for up to 3 months, though the texture of the potatoes may change slightly upon thawing.
