3 leeks, halved and sliced (white and light green parts only)
3 cloves garlic, minced
6 cups chicken stock
6 russet potatoes, halved and sliced with skins on
1 cup half & half
Salt and pepper to taste
Freshly cracked pepper for garnish
Green onions, sliced for garnish
Instructions
Cut off the dark green leaves of leeks, keeping only white and light green sections (about 3 cups sliced). Slice each leek in half lengthwise, then cut into semi-circles. Place in bowl of cool water, swish to release sand, then lift out and drain in colander.
Cut unpeeled potatoes in half lengthwise, then slice each half into 1/4 inch thick pieces.
Melt 1 stick of butter over medium-low heat in large stock pot.
Add leeks to butter and cook for 8-10 minutes, stirring often, until very soft and translucent.
Add minced garlic and cook for 1 minute, stirring constantly.
Pour in chicken stock and add sliced potatoes. Liquid should come about three-quarters up the sides of potatoes.
Increase heat to medium and bring to boil, then reduce to gentle simmer. Cook for 20 minutes until potatoes are fork-tender and soup naturally thickens.
Remove from heat. Stir in 1 cup half & half until fully combined. Soup will continue to thicken as it cools.
Season with salt and pepper to taste (start with 1/2 teaspoon salt). Serve immediately, garnishing each bowl with freshly cracked pepper and sliced green onions.
Notes
Use russet potatoes for best natural thickening. Their high starch content creates creamy texture without pureeing.
Clean leeks thoroughly by swishing in water to remove hidden sand between layers. You should have about 3 cups sliced leeks.
Substitute heavy cream for thicker soup or whole milk for lighter version.
Soup thickens considerably when refrigerated. Add extra stock or milk when reheating.
Can freeze soup base without half & half for up to 3 months. Add fresh dairy when reheating.
Use good quality or homemade chicken stock for best flavor. Vegetable stock works for vegetarian version.
