Ingredients & Substitutions

Ingredient List

• 2 tablespoons extra virgin olive oil

• ¾ teaspoon salt, plus more to taste

Notes on Quality

• Leeks: Fresh is best, but frozen (pre-sliced) leeks can work in a pinch just thaw and drain.
• Potatoes: Yukon Golds give that buttery, creamy texture. Russets can work but may be starchier.
• Broth: Homemade is gold, but any low-sodium veggie broth or bouillon works beautifully.
• Skyr: Look for plain, full-fat for best flavor. Greek yogurt makes a great backup.

Possible Substitutions

• Skyr: Greek yogurt, crème fraîche, or sour cream are good swaps.
• Herbs: Try dill, tarragon, or parsley if you don't have chives.
