  • ½ cup chicken stock
  • ½ cup milk
  • 1 tablespoon butter
  • 1 tablespoon all-purpose flour
  • 3 garlic cloves
  • 3 lemons (juice only)
  • ¼ teaspoon salt
  • ¼ teaspoon pepper
  • ½ teaspoon apple cider vinegar
  • ½ teaspoon dried parsley


  • Melt butter in a pot on the stove top over medium heat.
    1 tablespoon butter
  • Add flour. Quickly whisk the flour and butter together to form a paste, and cook this for a few seconds while stirring.
    1 tablespoon all-purpose flour
  • Combine milk and chicken stock, and pour a splash of the liquid into the pot. Whisk until the liquid is incorporated into the flour paste, then add a little more. Continue to gradually add liquid until the sauce has an even, smooth consistency.
    ½ cup chicken stock, ½ cup milk
  • Add very finely diced garlic, apple cider vinegar and seasoning to the sauce, and keep whisking. The sauce will gradually thicken. Add additional seasoning, and lemon juice to taste. I like to squeeze half a lemon at a time, and then check to see if more is needed. Serve the sauce immediately.
    3 garlic cloves, 3 lemons, ¼ teaspoon salt, ¼ teaspoon pepper, ½ teaspoon apple cider vinegar, ½ teaspoon dried parsley



  • This sauce can be stored in a refrigerator for up to 3 days, and reheated or served cold. It's perfect for making ahead!
  • Make it vegan by using oat milk or soy milk and a vegan butter substitute.
  • Make sure to whisk and stir the sauce continuously, from when you add the flour, until the sauce has thickened. This is the easiest way to prevent lumpy sauce.
