Recipe Info

Ingredients You’ll Need

• 3 large leeks (white and light green parts only, sliced and rinsed well)
• 2 tablespoons olive oil (or dairy-free butter)
• 2 cloves garlic, minced
• 5 medium Yukon Gold potatoes (about 2 lbs, peeled and diced)
• 1 medium onion, chopped
• 6 cups vegetable broth (low-sodium preferred)
• 1 teaspoon salt (adjust to taste)
• ½ teaspoon black pepper
• 1 bay leaf
• Fresh thyme sprigs (or 1 teaspoon dried thyme)
• Optional garnish: chopped fresh chives, parsley, or a drizzle of olive oil

Step-By-Step Instructions

1. Prep the vegetables – Slice the leeks lengthwise, rinse well to remove grit, and slice into thin half-moons. Peel and dice the potatoes into small chunks for quicker cooking.
2. Sauté the aromatics – In a large pot, heat the olive oil over medium heat. Add leeks, onion, and garlic, stirring occasionally for 6–8 minutes until softened and fragrant.
3. Add the potatoes and broth – Stir in the diced potatoes, bay leaf, thyme, salt, and pepper. Pour in the vegetable broth and bring to a gentle boil.
4. Simmer until tender – Reduce heat and let the soup simmer uncovered for 20–25 minutes, until the potatoes are soft and break apart easily.
5. Blend until creamy – Remove the bay leaf. Use an immersion blender to puree the soup until smooth (or carefully transfer to a blender in batches). Adjust thickness with extra broth if needed.
6. Taste and adjust – Add more salt or pepper to your liking. Serve hot, garnished with fresh herbs or a drizzle of olive oil.

Helpful Notes & Tips

• Cleaning leeks: Always rinse thoroughly, as leeks trap dirt between layers.
• Texture control: Blend fully for a creamy soup, or leave it slightly chunky for rustic appeal.
• Storage: Refrigerate leftovers in an airtight container for up to 4 days, or freeze for up to 3 months. Reheat gently on the stovetop.

Recipe Variations

• Add greens – Stir in a few handfuls of spinach or kale at the end for extra nutrients.
• Make it protein-rich – Add cooked shredded chicken or white beans for heartiness.
• Herb swap – Use rosemary or dill instead of thyme for a flavor twist.

Serving Suggestions

• Serve with crusty bread or warm sourdough for dipping.
• Pair with a crisp green salad for a light dinner.
• Top with crispy fried leeks or roasted chickpeas for extra crunch.
