Learn how to make a smooth, creamy white sauce from scratch. This beginner cooking lesson teaches you how to make a roux, add milk without creating lumps, adjust the thickness, and turn one basic sauce into cheese sauce, garlic sauce, Alfredo-style sauce, casseroles, and more.
White sauce, also called Bechamel sauce, is one of the five classical mother sauces. It begins with a roux made from butter and flour. Milk is then whisked into the roux and gently cooked until the sauce becomes smooth and creamy.
Learning this one technique gives you the foundation for many familiar recipes, including macaroni and cheese, creamy casseroles, vegetable sauces, garlic pasta, Alfredo-style sauces, and homemade cream soup substitutes.
This lesson focuses on the basic cooking skills behind white sauce: measuring equal amounts of butter and flour, whisking in liquid gradually, controlling the heat, and adjusting the finished sauce to suit your recipe.

White sauce is a simple milk-based sauce thickened with a roux. A roux is made by cooking butter and flour together before adding liquid. The flour thickens the milk, while the butter helps create a smooth texture and prevents the flour from clumping.
| Ingredient | Purpose |
|---|---|
| Butter | Provides richness and combines with the flour to form the roux. |
| Flour | Thickens the sauce. |
| Milk | Creates the creamy base. |
| Salt and Pepper | Season the finished sauce. |
| Start With | Add | Create |
|---|---|---|
| White Sauce | Cheddar or Parmesan | Cheese Sauce |
| White Sauce | Garlic and Parsley | Garlic Sauce |
| White Sauce | Parmesan and Extra Butter | Alfredo-Style Sauce |
| White Sauce | Chicken, Mushrooms, or Celery | Cream Soup Substitute |
White sauce is closely connected to the Bechamel mother sauce. Once you master this basic version, you can adapt it for pasta, vegetables, casseroles, soups, and many family meals.
This simple white sauce is the foundation for countless recipes. Once you learn this easy recipe, you can create cheese sauce, garlic sauce, creamy pasta dishes, casseroles, homemade cream soups, and many other family favorites.
The photos below show exactly how butter, flour, and milk come together to make a smooth white sauce.
A roux (pronounced roo) is simply butter and flour cooked together before adding liquid. Follow these four easy steps to make a smooth, lump-free sauce every time.
Place the butter in a small saucepan over medium heat. Allow it to melt completely without letting it brown.
Sprinkle the flour over the melted butter and whisk until the mixture becomes smooth. Continue cooking for about one minute to remove the raw flour taste.
Slowly pour in the milk while whisking constantly. If you're making another type of sauce, you can substitute chicken, vegetable, or fish stock instead of milk.
Continue stirring until the sauce thickens. Add cheese, garlic, herbs, or other seasonings depending on the recipe you're making.
Your finished white sauce can be served over pasta, vegetables, baked potatoes, chicken, fish, or used as the base for casseroles and creamy soups.
| Ingredient | Amount |
|---|---|
| Butter | 1 tablespoon |
| Flour | 1 tablespoon |
| Milk | 1 cup |
This simple 1 : 1 : 1 cup formula is easy to remember and can be doubled or tripled when making larger batches.
The same roux used to make white sauce is also the starting point for cheese sauce, homemade cream soups, gravies, and many casserole recipes. Learning this one technique opens the door to hundreds of recipes.
Every cook has a batch of white sauce that turns out too thick, too thin, or a little lumpy. Fortunately, most problems are easy to fix. Use these tips to rescue your sauce and improve your sauce-making skills.
| If This Happens... | Try This |
|---|---|
| Lumpy Sauce | Whisk vigorously while the sauce is still warm. If needed, pour the sauce through a fine-mesh strainer. |
| Too Thick | Whisk in a little warm milk until the sauce reaches the consistency you want. |
| Too Thin | Continue simmering while stirring. The sauce will thicken as excess liquid evaporates. |
| Raw Flour Taste | Cook the roux for about one minute before adding the milk. |
| Scorched Bottom | Reduce the heat and stir constantly. If the sauce burns, pour the unburned portion into a clean pan without scraping the bottom. |
| Use | Consistency |
|---|---|
| Vegetables | Thin and pourable |
| Pasta | Creamy enough to coat the noodles |
| Casseroles | Medium thickness |
| Macaroni & Cheese | Thicker before adding the cheese |
White sauce continues to thicken slightly as it cools. If you're making it ahead of time, keep it a little thinner than your final desired consistency. You can always whisk in a splash of milk when reheating.
Once you've mastered the basic recipe, you can easily change the flavor by adding different herbs, cheeses, or seasonings. These simple variations are great ways to practice building new sauces from one basic recipe.
| Add This... | Create... |
|---|---|
| Cheddar cheese | Cheese Sauce |
| Parmesan cheese | Alfredo-Style Sauce |
| Garlic and parsley | Garlic White Sauce |
| Italian seasoning | Italian Cream Sauce |
| Cooked mushrooms | Mushroom Sauce |
| Cooked onions | Onion Cream Sauce |
This creamy garlic pasta is one of the easiest ways to use homemade white sauce. The sauce comes together while the pasta cooks, making it a quick weeknight meal or side dish. Serve it immediately for the smoothest, creamiest texture.
Pasta continues to absorb sauce after it's mixed together. If the dish sits too long, it may become dry. For the best results, combine the pasta and sauce just before serving. If needed, stir in a splash of warm milk when reheating leftovers.
Once you've mastered the basic sauce, try these simple family recipes that build on the same technique.
Creamy bacon and pea pasta is a simple family meal that turns basic white sauce into a hearty dinner. Crispy bacon adds smoky flavor, peas add color and sweetness, and Parmesan cheese creates a rich, creamy finish.
Serve creamy bacon and pea pasta with a green salad, steamed vegetables, garlic bread, or fresh fruit for a balanced family meal.
Once you know how to make a basic white sauce, you can use the same technique in many family meals. These recipes help you practice making a roux, thickening milk, adding cheese, and turning one simple sauce into casseroles, pasta dishes, soups, and baked meals.
Watch the video below to see how butter, flour, and milk come together to form a smooth white sauce. Pay attention to how slowly the milk is added and how often the sauce is whisked.
Basic white sauce is made from butter, flour, and milk. The butter and flour are cooked together to make a roux, then milk is gradually whisked in until the sauce becomes smooth and thick.
Yes. Bechamel is the classical name for a white sauce made with a roux and milk. Home cooks often season it simply with salt and pepper, while other recipes add cheese, garlic, herbs, or vegetables.
Lumps usually form when the milk is added too quickly or the sauce is not whisked continuously. Add the liquid gradually and keep whisking. If lumps remain, strain the warm sauce through a fine-mesh sieve.
Whisk in a small amount of warm milk until the sauce reaches the consistency you need. Add only a little at a time so it does not become too thin.
Continue simmering the sauce gently while stirring. It will thicken as it cooks. If it is still too thin, make a small amount of roux separately and whisk it into the sauce.
Yes. A medium-thick white sauce can replace canned cream soup in many casseroles, pot pies, pasta dishes, and slow cooker recipes. Add cooked chicken, mushrooms, celery, or seasonings to match the flavor you need.
Yes. Cool the sauce, cover it, and refrigerate it. Reheat slowly over low heat while whisking in a splash of milk to restore its smooth texture.
Kids can help measure ingredients, whisk the flour into the butter, add seasonings, and stir with close adult supervision. An adult should handle the hot saucepan and stovetop as needed.
Continue practicing roux-making, sauce thickening, seasoning, and other beginner cooking techniques with these related lessons.
Mastering white sauce teaches you how to make a roux, thicken liquids, control heat, and adjust seasonings. Use these skills in pasta dishes, casseroles, soups, gravies, vegetables, and many other family recipes.
