Ingredients

  • 1 tablespoon extra virgin olive oil
  • 1 medium yellow onion chopped (2 1/2 cups)
  • 2 cloves garlic minced
  • 1 pound yukon gold potatoes peeled and cut into 1-inch pieces
  • 1 bunch asparagus tough ends trimmed and cut into 1-inch pieces
  • 3 cups low-sodium chicken or vegetable stock
  • 1 cup milk I used whole milk
  • 1 teaspoon kosher salt or to taste
  • 1/2 teaspoon ground black pepper or to taste
  • squeeze of lemon juice
  • Optional: croutons or crusty bread for serving

Instructions

  • Heat olive oil in saucepan or dutch oven over medium-low heat, then add the onions and a pinch of salt. Cook, stirring occasionally, for 5-7 minutes, until translucent and starting to brown. Stir in the garlic and cook for an additional minute.

Notes

Storage Instructions
Let the soup cool completely before storing. You can keep it in an airtight container in the fridge for up to 4 days. It reheats beautifully on the stovetop or in the microwave - just give it a good stir and add a splash of water, stock or milk, if it thickens up too much.
You can also freeze this soup. Transfer to a freezer-safe container and freeze for up to 2 months. Thaw overnight in the fridge and reheat gently. Give it a good whisking or blitz with an immersion blender if it has separated a bit (this may happen due to the milk in the recipe).
