Cook Time: 15 minutes
Total Time: 15 minutes

Ingredients

  • 1/4 cup unsalted butter
  • 2 leeks white and light greens only, sliced and cleaned
  • 2-3 cloves fresh garlic minced
  • 2 tablespoons flour
  • 1 cup half & half
  • 1/4 cup low sodium vegetable broth
  • 1 fresh lemon juiced and zested
  • 1/3 cup parmesan cheese finely grated
  • 1/2 teaspoon coarse sea salt

Instructions

  • In a medium saucepan over low-medium heat, melt the 1/4 cup unsalted butter.
  • Add the cleaned and sliced 2 leeks, stirring to coat and then cooking down for 4-5 minutes. Leek should cook down, but not be browned. Add the minced 2-3 cloves fresh garlic, cooking for an additional minute.
  • Stir in the 2 tablespoons flour, creating a roux paste.
  • Whisk in the 1 cup half & half and 1/4 cup low sodium vegetable broth, reduce heat to low.
  • Remove from the heat and whisk in the zested and juiced 1 fresh lemon, finely grated 1/3 cup parmesan cheese, 1/2 teaspoon coarse sea salt and 1/4 teaspoon ground black pepper. Mixture should coat the back of a spoon when the cheese has melted.
  • Serve hot over chicken, pork, seafood, pasta or veggies.

Notes

Storage: Store any leftover creamy leek sauce in an airtight container in the refrigerator. It should last for up to three days.
Freezing: Unfortunately I do not recommend freezing cream based sauces. They tend to separate.
