14 - 7 ounces cooked seafood such as shrimp, scallops, or white fish, or 4 strips cooked bacon, crumbled, or fresh chopped chives or parsley
# How-To Steps:
01 - In a large soup pot, heat butter and olive oil over medium heat. Add leeks and onion, cooking for 5–6 minutes until softened but not browned.
02 - Add minced garlic and diced celery, sautéing for 2 minutes until fragrant.
03 - Stir in diced potatoes, bay leaf, thyme, salt, and pepper. Pour in the broth and bring to a boil.
04 - Reduce heat to low, cover, and simmer for 20–25 minutes until potatoes are very tender and easily pierced with a fork.
05 - Remove the bay leaf. Use an immersion blender to purée the soup until smooth, or leave slightly chunky if preferred.
06 - Stir in the milk and gently reheat over low heat. Adjust seasoning as needed.
07 - For seafood variation: fold in cooked seafood and heat through for 2–3 minutes. For bacon variation: ladle soup into bowls and top with crumbled bacon.
08 - Garnish with fresh chives or parsley as desired. Serve hot.
