Step-by-Step Instructions

  1. In a Dutch oven or stock pot, heat oil and/or butter to medium heat.
  2. Add onion; 3-4 minutes or until slightly soft.
  3. Add asparagus; cook another 3-4 minutes or until soft. Stir in garlic, salt, black pepper, dill, oregano and red pepper flakes; cook 30-60 seconds or until garlic is fragrant.
  4. Stir in potatoes and stock. Bring to a low simmer; cook 20-25 minutes or until potatoes are very soft.
  5. Use an immersion blender to puree until very smooth.
  6. Alternatively, carefully transfer soup to a high-powered blender; let slightly cool, then puree until very smooth; transfer back to the pot.
  7. Stir in vinegar and lemon juice. Taste and adjust seasoning, if necessary.

Recipe Substitutions and Alterations

  • For the fat: Use olive oil and/or butter to saute the onions and garlic. I like to do 2 tablespoons olive oil + 1 tablespoon butter for optimal flavor.
  • For the onion: Use white or yellow onion. For a shortcut, you can use frozen diced onions.
  • For the asparagus: Fresh is best, but frozen would work as well.
  • For the potatoes: Use yukon gold or white potatoes. You could use reds, but it’s best to peel them.
  • For the herbs: Adjust how much of each herb and spice you’d like to use. You can also add some fresh dill, chives and/or parsley, if you’d like.
  • For the acid: If you don’t have sherry vinegar, use a little white wine vinegar.
  • For a richer soup: Add a few tablespoons of half-and-half or heavy cream.
