Recipe Questions & Answers

Can I freeze this soup?

Yes, freeze without the milk or cream. Thaw overnight in the refrigerator, reheat gently, and stir in dairy just before serving. The soup keeps well for up to 3 months.

What potatoes work best?

Yukon Gold or other waxy varieties are ideal—they break down slightly for creaminess while maintaining some texture. Avoid russets which can become gluey when blended.

How do I clean leeks properly?

Slice leeks lengthwise, fan out layers under running water to remove trapped grit and sand. Pat dry before cooking to prevent excessive splattering when sautéing.

Can I make this dairy-free?

Absolutely. Use all olive oil instead of butter and substitute coconut milk, almond milk, or cashew cream for dairy milk. The result remains silky and satisfying.

What's the best way to achieve smooth texture?

An immersion blender works perfectly directly in the pot. For ultra-smooth results, use a regular blender in batches, venting slightly to release steam. A potato masher creates a rustic chunky version.

How long will leftovers keep?

Store in an airtight container in the refrigerator for 4-5 days. The flavors often improve after a day. Reheat gently over low heat, adding a splash of broth if needed.
