Quick Lemon Butter Sauce in 5 Minutes for Fish & Pasta

Make a super-easy, bright lemon butter sauce for chicken, pasta, fish, or steamed vegetables. It’s light, tangy, and made with fresh lemon juice and real butter—no preservatives, additives, or artificial colors.

By heating the fresh lemon juice first, the butter emulsifies into the juice without the need for flour or cornstarch. The sauce comes together in minutes and has a clean, fresh lemon flavor balanced by butter.

Ingredients

Simple ingredients deliver maximum flavor: fresh lemon juice, salted butter, salt, and white pepper. Optional buttermilk can be added for extra creaminess.

Here’s how you make it

  • Cut the butter into small pieces and set aside so it melts evenly.
  • In a medium saucepan, heat the lemon juice over high heat until it just starts to bubble, then reduce the heat to low.
  • Add the butter a few pieces at a time and whisk on low until the mixture is smooth and fully combined.
  • Season with salt and white pepper to taste. Serve immediately over your dish of choice.

This sauce takes less than five minutes to make and reheats easily. If you have leftovers, store them in the refrigerator and reheat gently (see storage notes).

Recipe tips

  • If the sauce starts to separate or “break,” remove the pan from heat and whisk in a splash of cold water until it re-emulsifies.
  • For a creamier texture, stir in 2 teaspoons of buttermilk just before serving.

Storage and reheating

Store leftover sauce in a sealed jar in the refrigerator for up to 5 days.

To reheat, warm the sauce gently in a pan over medium-low heat, whisking until smooth. If it becomes too thick, whisk in a tablespoon of water at a time until you reach the desired consistency.

Variations

Add fresh or dried herbs to customize the sauce for different dishes. Fresh herbs are milder—add them at the end of cooking. If using dried herbs, reduce the amount because they’re more concentrated.

  • Dill: pairs beautifully with fish and poultry.
  • Rosemary: good with roasted chicken, pork, or beef.
  • Sage: works well with turkey, pork, or richer meats.
