  3. Decrease heat to simmer, and continue to cook, covered until needed in step 5.
  4. Meanwhile, melt butter in a large Dutch oven over med-high heat; stir in leeks, garlic, and 1/4 teaspoon salt; cover and cook until leeks are wilted and softened, about 10 minutes.
  5. Stir in broth mixture; bring to simmer and cook until potatoes are tender, 4-7 minutes.
  6. Off heat, remove bay leaves and mash some of the potatoes against side of pot to thicken soup to desired consistency.
