# How-To Steps:

01 - Melt butter in a large pot over medium heat. Add leeks and onion, sauté for 6–8 minutes until softened but not browned.
02 - Stir in minced garlic and cook for 1 minute until fragrant.
03 - Add potatoes, vegetable broth, salt, pepper, thyme, and bay leaf. Bring to boil, then reduce heat to simmer. Cover and cook 20–25 minutes until potatoes are very tender.
04 - Remove and discard the bay leaf from the pot.

07 - Gradually add grated sharp cheddar, stirring constantly until melted and fully incorporated. Taste and adjust seasoning as needed.
08 - Ladle soup into bowls, garnish with extra cheddar and chives or scallions. Serve hot.

# Expert Advice:

01 -
  • This soup bridges the gap between winter comfort and spring freshness, feeling substantial without weighing you down
  • The sharp cheddar creates these incredible salty pockets throughout every spoonful, making each bite distinct from the last
  • It comes together in under an hour but tastes like it simmered all day, earning you compliments you barely had to work for
02 -
  • Leeks hide dirt between their layers, slice them lengthwise and swish them in a bowl of cold water before cooking
  • The soup will thicken as it stands, thin it with a splash more broth or milk when reheating leftovers
  • Add the cheese off the heat or at very low temperature, high heat makes dairy proteins seize and turn grainy
03 -
  • Grate your own cheese instead of buying pre shredded, which contains anti caking agents that prevent smooth melting
  • Room temperature cream incorporates more easily than cold, which can cause the cheese to separate when it hits the hot soup
