Butter sauce, also known as beurre blanc, is a classic French sauce made from a mixture of butter, shallots, and a liquid such as wine or vinegar. It’s a popular accompaniment to seafood, meat, and vegetables, but it can be tricky to thicken without using cornstarch. In this article, we’ll explore the reasons why cornstarch is often used to thicken butter sauce, and provide alternative methods for achieving the perfect consistency.
Why Cornstarch is Used to Thicken Butter Sauce
Cornstarch is a common thickening agent used in many sauces, including butter sauce. It’s a starchy powder extracted from corn, and it works by absorbing excess liquid and swelling to form a gel-like texture. When added to a hot liquid, cornstarch dissolves and forms a network of starch molecules that trap liquid and thicken the sauce.
However, some cooks may not have cornstarch on hand, or they may prefer not to use it due to its processed nature or potential health effects. Fortunately, there are several alternative methods for thickening butter sauce without cornstarch.
Alternative Methods for Thickening Butter Sauce
Method 1: Reducing the Liquid
One of the simplest ways to thicken butter sauce is to reduce the liquid by cooking it for a longer period. This method works by evaporating excess water and concentrating the flavors and solids in the sauce. To reduce the liquid, simply simmer the sauce over low heat for 10-15 minutes, stirring occasionally, until it reaches the desired consistency.
Method 2: Using Roux
A roux is a mixture of flour and fat that’s used to thicken sauces. To make a roux, melt a small amount of butter or oil in a pan, then add an equal amount of flour. Cook the mixture for 1-2 minutes, stirring constantly, until it forms a smooth paste. Gradually add the liquid to the roux, whisking constantly to prevent lumps. Bring the mixture to a simmer and cook for 2-3 minutes, until it thickens.
Method 3: Using Egg Yolks
Egg yolks can be used to thicken butter sauce by adding richness and body. To use egg yolks, beat them lightly in a bowl, then gradually add a small amount of the warm sauce to the eggs, whisking constantly. This is called tempering the eggs, and it prevents them from scrambling when added to the hot sauce. Once the eggs are tempered, gradually add them to the sauce, whisking constantly to prevent lumps.
Method 4: Using Cream or Crème Fraîche
Adding a small amount of cream or crème fraîche can help to thicken butter sauce and add richness and flavor. Simply stir in a tablespoon or two of cream or crème fraîche towards the end of cooking, and cook for an additional minute or two until the sauce thickens.
Tips for Thickening Butter Sauce
- Use a high ratio of butter to liquid. This will help to create a rich and creamy sauce that’s less likely to be too thin.
- Don’t overheat the sauce. High heat can cause the sauce to break and separate, resulting in an unappetizing texture.
- Whisk constantly. Whisking helps to distribute the thickening agents evenly and prevents lumps from forming.
- Add thickening agents gradually. Adding thickening agents too quickly can result in a sauce that’s too thick or lumpy.
Common Mistakes to Avoid
- Adding too much liquid. This can result in a sauce that’s too thin and difficult to thicken.
- Not cooking the sauce long enough. Failing to cook the sauce for a sufficient amount of time can result in a sauce that’s too thin or raw-tasting.
- Not whisking constantly. Failing to whisk constantly can result in a sauce that’s lumpy or uneven.
Conclusion
Thickening butter sauce without cornstarch is a simple process that requires a little patience and practice. By using one of the alternative methods outlined above, you can create a rich and creamy sauce that’s perfect for accompanying your favorite dishes. Remember to use a high ratio of butter to liquid, don’t overheat the sauce, whisk constantly, and add thickening agents gradually. With a little practice, you’ll be creating delicious butter sauces like a pro.

What is the purpose of thickening butter sauce?
Thickening butter sauce is essential to achieve the desired consistency and texture in various dishes. A thickened butter sauce can coat the food evenly, enhancing the overall flavor and presentation. It is particularly important in French cuisine, where butter sauces are a staple in many classic recipes.
By thickening the butter sauce, you can prevent it from becoming too runny or separating, which can be unappetizing. Thickening agents help to stabilize the sauce, allowing it to maintain its texture and consistency even when served hot or cold. This is especially crucial when serving the sauce over delicate foods, such as fish or vegetables, where a thin sauce might not provide enough flavor or texture contrast.
Why can’t I use cornstarch to thicken butter sauce?
Cornstarch is a common thickening agent, but it’s not the best choice for thickening butter sauce. Cornstarch can leave a starchy or chalky texture in the sauce, which can be unpleasant. Additionally, cornstarch can break down when exposed to high heat or acidic ingredients, causing the sauce to thin out or become uneven.
Furthermore, cornstarch can also affect the flavor of the butter sauce, giving it a slightly starchy or bland taste. In contrast, other thickening agents like egg yolks, cream, or roux can add richness and depth to the sauce, making it more flavorful and aromatic. By avoiding cornstarch, you can create a more refined and sophisticated butter sauce that complements your dishes.
What are some alternatives to cornstarch for thickening butter sauce?
There are several alternatives to cornstarch that you can use to thicken butter sauce. One popular option is egg yolks, which can be whisked into the sauce to create a rich and creamy texture. Another option is heavy cream or crème fraîche, which can be added to the sauce to give it a luxurious and velvety texture.
You can also use a roux made from butter and flour to thicken the sauce. This method involves cooking the butter and flour together to create a smooth and creamy paste, which can then be whisked into the sauce. Other options include using grated cheese, such as Parmesan or Gruyère, or adding a slurry made from flour and water.
How do I thicken butter sauce with egg yolks?
To thicken butter sauce with egg yolks, start by whisking the egg yolks in a separate bowl until they become light and fluffy.
