Once you know how to make lemon butter sauce for fish, you’re going to want to put it on everything! There’s your warning. 😉 It’s hard to believe that three simple ingredients can elevate seafood in such an elegant, flavorful way, but this lemon garlic butter sauce recipe lives up to the challenge and can be used in so many ways.
One of the reasons I think this is the best lemon butter sauce for fish is because it’s so versatile! Whether you’re serving it with seafood like lobster tails or pan-fried halibut (which is how I originally made it!), this sauce is also great on veggies like zucchini noodles or sauteed broccoli.
What Is Lemon Butter Sauce?
This lemon butter sauce recipe is light and rich at the same time. It’s essentially a lemon and garlic flavored, emulsified butter, and it’s incredible on seafood in particular.
Lemon And Butter Sauce Ingredients
This easy lemon garlic butter sauce for fish is made of only 3 ingredients that you probably already have at home:
How To Make Lemon Butter Sauce
- Melt butter. It will bubble a bit.
TIP: Use an enameled saucepan like this, so that you can see color changes.
- Add lemon and garlic. Stir in lemon juice and garlic powder, and continue to heat until the sauce turns darker yellow. Remove from heat right away.
TIP: Watch carefully – it will burn easily if heated too long! The time can vary if you use a different type of pan than I did.
Lemon Garlic Butter Sauce FAQs
Is lemon butter sauce healthy?
I’ll leave the answer up to you, depending on how you feel about buter, which is the primary ingredient. Butter doesn’t have the negative connotation that it used to, and I like to get grass-fed butter for extra benefits.
Can I use garlic cloves instead of garlic powder?
Yes, you can use minced or crushed garlic, but may want to add it toward the very end. I used garlic powder, because it has less risk of burning and it’s faster.
Why did my sauce separate?
This can happen if your heat is too high, or if you use bottled lemon juice, which often has water added. Be sure to use freshly squeezed lemon juice.
Why is my sauce thin?
It’s supposed to be thin! But if you do want to it thicker, you can add some cornstarch (not low carb) or xanthan gum to thicken it.
Why did my lemon butter sauce turn brown?
You may have overcooked the sauce a bit and now it’s a brown butter lemon sauce! It’s still fine to eat and will have a nice, nutty flavor.
Alternatively, you can strain it through a fine-mesh sieve to remove any brown bits. It will still be a more golden color and have some browned butter flavor.

Can you make it ahead?

Can you freeze lemon butter sauce?
