Editorial Guidelines Updated on November 20, 2023 Rate PRINT Share Yield: 3 cups One of the mother sauces of French cuisine, béchamel is a true classic. This simple white sauce is made with milk, butter, and flour, and is the basis of other sauces and used in many recipes, from gratins to macaroni and cheese. We use this silky, creamy béchamel sauce for Lasagna Bolognese, where it holds the layers of pasta together and provides a rich counterpoint to the acidity of the tomatoes. Kelsey Hansen Any cook who has made a lumpy béchamel knows the pain of seeing the sauce turn clumpy. The secret to success with a béchamel sauce recipe is to cook the roux long enough to avoid a floury taste, and over medium-low heat, being careful not to let it brown. Another tip: whisking constantly while adding flour, then milk, prevents lumps from forming. Lasagna With Meat Sauce What Is Béchamel Sauce? A classic French sauce, a béchamel is made with flour, butter, and milk. It is used in many dishes from lasagna to macaroni and cheese to gratins and casseroles to croque monsieur. The butter and flour are cooked together in a heavy-bottomed saucepan to form a thick paste (the roux) before milk is added. A béchamel uses a white roux, one that has been cooked very quickly to maintain its light color and subtle, nutty flavors. Milk is slowly whisked into the roux and cooked until it takes on a creamy consistency, thickening to the texture required. (Some recipes call for a thick sauce, whereas for use in lasagna, the béchamel needs to have a pourable consistency.) The sauce is then seasoned with salt, pepper, and nutmeg. What Is a Roux? A roux is a combination of flour and fat that is cooked together and used as a base to thicken and flavor sauces. The method for making a roux uses roughly equal parts oil or butter or another fat to flour. The roux is whisked constantly as it cooks until it reaches an optimal shade of color. Depending on the recipe, that color can range from white to dark brown. The finished base can be used to thicken sauces, gravies, soup, gumbo, and other dishes. Nutmeg in Béchamel It’s worth mentioning the use of nutmeg in béchamel sauce because you might not notice it. This spice—that you might be familiar with from eggnog or holiday cookies—is a subtle but necessary addition. It brings warmth, spice, and complexity to the blank canvas that is white sauce. How to Avoid Lumps in a Béchamel Sauce A lumpy sauce is the last thing you want; follow these simple steps to prevent the sauce from clumping: Use warm, not cold, milk (that’s why our recipe calls for heating the milk).Add the milk to your roux in increments; this gives the roux chance to accept the liquid evenly. If you add the milk all at once, the roux will seize and create lumps that are difficult to remove. Ingredients 7 tablespoons unsalted butter 6 tablespoons all-purpose flour 3 ½ cups milk, heated just until steaming Pinch of freshly grated nutmeg ½ teaspoon coarse salt Freshly ground pepper Directions Kelsey Hansen Melt butter: Melt butter in a heavy-bottomed, medium saucepan over medium-low heat. Kelsey Hansen Add flour and cook roux: Add flour, whisking constantly. Cook, whisking occasionally, 2 to 3 minutes; do not let roux brown. Kelsey Hansen Whisk in small amount of hot milk: Whisking constantly, add about 2 tablespoons hot milk to saucepan. Kelsey Hansen Add more milk, whisking constantly: Pour half of the remaining hot milk into the saucepan in small increments, whisking the mixture constantly, until a smooth paste forms. Kelsey Hansen Whisk in remaining milk, nutmeg, and salt: Whisk remaining milk into pan; add nutmeg and salt. Kelsey Hansen Kelsey Hansen Cook, stirring: Cook, stirring with a wooden spoon, making sure to scrape bottom and sides, until sauce is thick and creamy, about 15 minutes; if any lumps form, stir sauce rapidly with a whisk. Kelsey Hansen Season and let stand to cool: Season with pepper; remove from heat. Let sauce stand until lukewarm, about 30 minutes, before assembling lasagna. Kelsey Hansen Make Ahead and Storage Kelsey Hansen This béchamel sauce is best used fresh, but it can be made one day ahead and stored in an airtight container in the refrigerator. Reheat gently in a heatproof bowl over a pan of simmering water before using. Frequently Asked Questions Why is béchamel used in lasagna? Using ricotta is easier than making a béchamel sauce, but like legions of other cooks, we think béchamel produces a more delicious lasagna. The rich, creamy sauce balances the acidity from the tomatoes and is better at keeping the layers of pasta together than ricotta. Does traditional lasagna have béchamel or ricotta? The components of a traditional lasagna vary depending on who you ask. It appears that béchamel sauce was used in northern Italy, and ricotta in the South. In the U.S., versions that use ricotta are preeminent. Should you use hot or cold milk for béchamel? As noted above and in the method for our béchamel sauce recipe, hot milk is best for making the sauce. Adding cold milk to the roux is likely to result in a lumpy sauce.
