Let’s cook together, shall we?

Whether you’re looking for an easy potato and leek soup or something to impress the in-laws, this recipe fits both bills.

Ingredients You’ll Need

Before we dive into the step-by-step, here’s what you’ll need to gather from your kitchen or local market. I’ve included tips and swaps, too!

• 1.9 lb potatoes (about 4 medium)
  • Use Russet or Yukon Gold. Avoid waxy potatoes.
• 1 large leek (about 3.8 oz)
  • Only use the white and light green parts. Save the dark greens for stock!
• 4 cups vegetable stock (or chicken stock)
• 2 Tbsp butter (or vegan butter)
• 2 Tbsp olive oil
• 1 garlic clove, minced
• 1 bay leaf
• 1 tsp salt (adjust to taste)
• 1/2 tsp black pepper
• 2-3 sprigs fresh thyme (or 1/2 tsp dried)
• 1/4 cup heavy cream (optional, or sub with milk, or leave out for a leek and potato soup without cream)

How to Clean Leeks (Because It’s Tricky!)

Leeks are sneaky. Dirt hides deep in their layers. Here’s how I clean them:

1. Slice off the root and dark green tops.
2. Slice the leek in half lengthwise.
3. Fan out the layers and rinse under running water.
4. Chop and rinse again in a bowl of cold water.

This step only takes 2 minutes but makes a big difference!

Step-by-Step: How to Make the Best Potato Leek Soup

You don’t need any fancy tools here. Just a big pot and a blender (or immersion blender).

1. Prep Your Ingredients

• Peel and chop your potatoes into 1-inch pieces.
• Clean and chop your leeks (see above).
• Mince the garlic.

2. Sauté the Aromatics

In a large soup pot or Dutch oven:

1. Heat butter and olive oil over medium heat.
2. Add the chopped leek, garlic, thyme, bay leaf, salt, and pepper.
3. Cook for 2-3 minutes, stirring often, until the leeks are soft and fragrant.

3. Simmer Everything

1. Add the potatoes to the pot.
2. Pour in your stock.
3. Bring it all to a boil, then reduce to a simmer.
4. Cover and cook for 15-20 minutes, or until the potatoes are fork-tender.

4. Blend the Soup

1. Remove the bay leaf.
2. Use an immersion blender to blend right in the pot. Or ladle the soup into a blender in batches.

Tip: When using a stand blender, leave a gap for steam to escape. I learned the hard way (soup on the ceiling…not cute).

5. Add Cream (Optional But Delicious)

1. Stir in your heavy cream or milk.
2. Taste and adjust seasoning.
3. Serve hot with your favorite toppings!

Family-Friendly Topping Ideas

• Shredded cheddar
• Crispy bacon bits
• Chopped chives or green onions
• Croutons (the kids’ favorite!)

Make It Your Own: Variations

This soup is super forgiving. Try these twists:

• Use milk instead of cream for a lighter version
• Add a handful of spinach or kale at the end for extra greens
• Stir in some cooked white beans for protein
• Make it spicy with crushed red pepper flakes
• Swap leeks for onions if you’re in a pinch

Storage + Reheating Tips

• Fridge: Store in an airtight container for up to 4 days.
• Freezer: Freeze in single portions for up to 3 months.
• Reheat: Gently on the stovetop or microwave. Add a splash of stock if it’s too thick.

What to Serve with Potato Leek Soup

I love making this on busy weeknights with simple sides. Here are a few:

• Crusty bread or garlic toast
• Grilled cheese (classic combo!)
