Caper butter sauce is made by combining butter with briny capers, often with lemon juice or zest. Some versions add parsley or garlic, but the basic sauce is simple and buttery. Its texture can range from melted butter with capers to a more emulsified sauce.
To make caper butter sauce, melt butter gently, stir in drained capers, then add lemon juice to taste. Keep the heat low so the butter does not brown or separate unless you specifically want a browned-butter version. Serve the sauce while warm.
Caper butter sauce pairs especially well with fish and seafood, including pan-seared fish and scallops. It also works with boiled potatoes, asparagus, and other simply cooked vegetables. Spoon on a little at first: the capers bring a concentrated, salty tang.
Drain capers before adding them to caper butter sauce. Rinse them briefly if they taste very salty, especially when packed in brine; salt-packed capers may need a longer soak. This helps keep the finished sauce from becoming overly salty.
You can make caper butter sauce ahead, but it is best served freshly prepared. Refrigerate leftovers in a covered container and rewarm them gently over low heat, stirring as they warm. The butter may separate, and the lemon and capers can lose some freshness.
Caper butter sauce can be frozen, but its texture may turn grainy or separate after thawing. Thaw it in the refrigerator, then warm it gently while whisking. For the smoothest result, make a fresh batch rather than relying on frozen sauce.
If caper butter sauce tastes too salty, stir in unsalted butter or a little lemon juice, and avoid adding any more salt. You can also dilute it with a little water or unsalted stock. Next time, drain or rinse the capers before using them.
Yes, caper butter sauce works well with pasta, especially alongside seafood or a simple lemon-and-herb pasta. Toss the warm sauce with cooked pasta, loosening it with a splash of pasta water if needed. Add the sauce gradually so the dish does not become greasy.
No. Caper butter sauce is defined by the capers and may simply be melted butter flavored with them. Beurre blanc is a French butter emulsion traditionally built on a reduction of wine and vinegar; capers can be added to it, but they are not essential.
Caper butter sauce can separate if the butter gets too hot or boils. Warm it gently over low heat and stir continuously. If it has already split, take it off the heat and whisk in a small splash of warm water to help bring the sauce back together.

Caper butter sauce combines melted butter with briny, tangy capers, often with lemon and herbs. It belongs to a broader European style of butter sauces and is especially familiar alongside fish, where the sharp capers balance butter’s rich, smooth flavour. Recipes vary: some keep it simple, while others add parsley or a splash of lemon juice.
Serve it spooned over pan-seared or grilled fish, or try a little with vegetables or chicken. It is very rich in fat and low in carbohydrates, so a small spoonful can bring plenty of flavour. For a lighter sauce, use less butter and add more lemon or herbs.
