Lemon Caper Sauce
Some sauces are complicated. They demand hours of simmering, a dozen obscure ingredients, and your undivided attention. This is not one of those sauces.
This Lemon Caper Sauce is the opposite. It’s your secret weapon for turning a simple piece of chicken or fish into something that tastes like it came from a high-end restaurant. It’s bright, zesty, and packed with a salty, briny punch from the capers.
With just a few pantry staples and about 10 minutes, you can create a sauce that elevates your entire meal. It’s proof that impressive flavor doesn’t have to be difficult.
What You’ll Need
The beauty of this sauce is its simplicity. You likely have most of these ingredients on hand already. Using high-quality, fresh ingredients will make a noticeable difference in the final taste.
- Unsalted Butter: Divided into 4 tablespoons for cooking and 2 tablespoons cold and cubed for finishing.
- Garlic: 2 cloves, minced finely.
- Chicken or Vegetable Broth: 1/2 cup of a good quality, low-sodium broth.
- Fresh Lemon Juice: 1/4 cup, from about 1-2 lemons. Do not use the bottled kind.
- Capers: 2 tablespoons, drained and preferably rinsed.
- Fresh Parsley: 2 tablespoons, chopped.
- Salt and Black Pepper: To taste.
Pro Tips
I’ve made this sauce hundreds of times. Here are a few key tips that guarantee a perfect result every time.
- Control Your Heat. The biggest mistake is burning the garlic. Start with a medium-low heat to melt the butter. The garlic should gently sizzle, not aggressively fry. Burnt garlic will make the entire sauce bitter.
- Rinse Your Capers. Capers are packed in a brine that is very salty. Giving them a quick rinse under cold water removes the excess salt, allowing their true floral, tangy flavor to shine through. This gives you more control over the final seasoning.
- The Cold Butter Finish. This is a classic French technique called “monter au beurre.” Adding cold, cubed butter at the very end, off the heat, while whisking constantly, emulsifies the sauce. It makes it creamy, glossy, and less likely to separate. Don’t just melt it in; whisk it in.
Tools Required
You don’t need any special equipment for this recipe, which makes it perfect for a quick weeknight meal.
- Small Saucepan
- Whisk
- Knife and Cutting Board
- Measuring Cups and Spoons
- Juicer or your hands for the lemon
Substitutions and Variations
This sauce is flexible. You can easily adapt it based on what you have available or your dietary preferences.
| Ingredient | Substitution | Notes |
|---|---|---|
| Unsalted Butter | Ghee or high-quality olive oil | The flavor will change. Olive oil will be less creamy. |
| Chicken Broth | Dry white wine or vegetable broth | Wine adds a sharp, acidic note. Cook off the alcohol first. |
| Capers | Finely chopped green olives | Provides a similar briny flavor but a different texture. |
| Fresh Parsley | Fresh dill, chives, or tarragon | Dill is excellent with fish. Chives add a mild onion flavor. |
Make-Ahead Tips
While this sauce comes together in minutes, you can prep parts of it to save even more time.
You can make the sauce through Step 3 and store it in the fridge for up to two days. When you are ready to serve, gently reheat it in the saucepan and then proceed with Step 4 to finish it with the cold butter and parsley for the best texture.
How to Make Lemon Caper Sauce: Step-by-Step
Follow these simple steps for a flawless sauce.
Step 1: In a small saucepan, melt 4 tablespoons of butter over medium-low heat.
Step 2: Add the minced garlic and cook for about 60 seconds, or until it becomes fragrant. Be careful not to let it brown.
Step 3: Pour in the broth, increase the heat to medium, and bring it to a simmer. Let it reduce by about a third, which should take 3-4 minutes. This concentrates the flavor.
Step 4: Remove the pan from the heat. Whisk in the fresh lemon juice and capers.
Step 5: Add the 2 tablespoons of cold, cubed butter, one piece at a time, whisking constantly until the butter is fully melted and the sauce is smooth and creamy.
Step 6: Stir in the fresh parsley. Season with a small amount of salt and pepper to your taste. Remember the capers and broth already contain salt.

Cooking Time Efficiency:
The best way to make this quickly is to practice “mise en place.” This means having all your ingredients measured, chopped, and ready to go before you even turn on the stove. Since the cooking process is so fast, you won’t have time to mince garlic or juice a lemon once you start.
Leftovers and Storage
If you have any leftover sauce, it can be stored easily.
Place the cooled sauce in an airtight container and keep it in the refrigerator for up to 3 days. To reheat, warm it gently in a saucepan over low heat, whisking occasionally. Do not microwave it, as the high heat can cause the sauce to break and separate.
Frequently Asked Questions
Q1. My sauce looks oily and separated. What went wrong?
Ans: This usually happens for one of two reasons. The heat was too high when you added the final cold butter, or you didn’t whisk continuously while adding it. Reheat gently and whisk vigorously to see if it will come back together.
Q2. Can I double the recipe?
Ans: Absolutely. This recipe scales very easily. Just use a slightly larger saucepan to give yourself enough room to whisk properly.
Q3. My sauce is too thin. How can I thicken it?
Ans: The best way is to let it reduce a bit longer on the stove before adding the final butter. You can also make a small slurry with 1 teaspoon of cornstarch and 1 tablespoon of cold water, whisk it in, and simmer for a minute before finishing the sauce.
Q4. Is there an alternative to capers?
Ans: If you don’t like capers, you can get a similar briny taste from finely chopped Kalamata or Castelvetrano olives. You could also leave them out and have a simple, delicious lemon butter sauce.
