Ingredients

  • 1/2 cup (1 stick) unsalted butter, cut into pieces
  • 3 cloves garlic, minced
  • 1 tablespoon fresh lemon juice, about half a lemon
  • 1 teaspoon lemon zest (optional, for extra citrus aroma)
  • 1 tablespoon fresh parsley, finely chopped
  • 1/4 teaspoon salt, or to taste
  • Freshly ground black pepper, to taste
  • Pinch of cayenne pepper (optional, for a subtle heat)

Equipment

  • Small saucepan or skillet
  • Measuring spoons
  • Whisk or spoon for stirring
  • Knife and cutting board
  • Citrus zester or microplane (optional)
  • Serving bowl or ramekin

Instructions

  1. Melt the butter: Place the butter in a small saucepan over medium-low heat. Allow it to melt slowly, stirring occasionally to prevent burning.
  2. Sauté the garlic: Once the butter has melted, add the minced garlic. Cook gently for 1-2 minutes, stirring frequently until the garlic becomes fragrant and just starts to turn golden. Be careful not to burn it.
  3. Add lemon and seasoning: Stir in the fresh lemon juice, lemon zest (if using), salt, black pepper, and cayenne pepper. Mix well to combine all flavors.
  4. Finish with parsley: Remove the saucepan from heat and stir in the chopped fresh parsley. This adds a fresh, herbaceous note and vibrant color to the sauce.
  5. Serve warm: Transfer the butter sauce to a serving bowl or ramekin. Serve immediately alongside steamed or boiled crab legs for dipping.

Tips & Variations

“For the best flavor, use fresh garlic and freshly squeezed lemon juice. Avoid pre-minced garlic or bottled lemon juice as they can alter the taste.”

  • Double the recipe if you’re serving a crowd—this sauce goes fast when paired with crab legs!
  • Add a splash of dry white wine or sherry during the garlic sauté step for a more complex flavor.
  • Mix in some finely chopped tarragon or chives for a unique twist on the classic parsley version.
  • If you prefer a creamy sauce, whisk in a tablespoon of heavy cream after the lemon juice step.
  • For a spicy kick, increase the cayenne pepper or add a few flakes of red chili.
  • Try substituting the unsalted butter with a garlic-infused butter or herb butter for extra aroma.
