Creating a white sauce is a fundamental skill in the kitchen, perfect for enhancing a variety of dishes. This creamy, versatile sauce can be used in pasta, casseroles, or as a base for other sauces. With just a few simple ingredients, you can whip up a delicious white sauce in no time.
All the ingredients for this white sauce recipe are commonly found in most kitchens. However, if you don't have all-purpose flour or butter, you will need to pick these up at the supermarket.

Ingredients for White Sauce Recipe
Butter: Adds richness and a smooth texture to the sauce.
All-purpose flour: Helps to thicken the sauce, creating a creamy consistency.
Milk: Provides the liquid base for the sauce, making it creamy and smooth.
Salt: Enhances the overall flavor of the sauce.
Pepper: Adds a touch of spice and depth to the sauce.
Technique Tip for This Recipe
When making a white sauce, ensure that the butter and flour are fully combined and cooked for at least one minute before adding the milk. This step, known as creating a roux, helps to eliminate any raw flour taste and ensures a smoother, creamier sauce.

How to Store / Freeze This Recipe
- Allow the white sauce to cool completely before storing. This prevents condensation, which can make the sauce watery.
- Transfer the cooled sauce into an airtight container. Glass jars or BPA-free plastic containers work best to maintain freshness.
- Label the container with the date of preparation. This helps you keep track of its shelf life.
- Store the container in the refrigerator. The white sauce will keep well for up to 5 days.
- For longer storage, consider freezing. Pour the sauce into a freezer-safe container, leaving some space at the top as the sauce will expand when frozen.
- Alternatively, freeze the sauce in ice cube trays for easy portioning. Once frozen, transfer the cubes to a zip-top freezer bag.
- When ready to use, thaw the sauce in the refrigerator overnight. Reheat gently in a saucepan over low heat, stirring frequently to maintain its creamy texture.
- If the sauce appears too thick after reheating, add a splash of milk or cream to reach the desired consistency.
- Avoid reheating the sauce multiple times, as this can affect its quality and flavor. Only reheat the amount you plan to use.
How to Reheat Leftovers
Gently reheat the white sauce on the stovetop over low heat. Stir constantly to prevent it from sticking or burning. If the sauce has thickened too much, add a splash of milk or cream to reach the desired consistency.
Use a double boiler to reheat the sauce. Fill the bottom pot with water and bring it to a simmer. Place the sauce in the top pot and stir occasionally until it’s warmed through. This method ensures even heating and prevents scorching.
Microwave the sauce in short intervals. Place the sauce in a microwave-safe bowl, cover it with a microwave-safe lid or plastic wrap with a small vent. Heat on medium power for 30-second intervals, stirring in between, until the sauce is hot and smooth.
If you’re reheating the sauce to use in a casserole or pasta dish, you can add it directly to the dish and bake it in the oven. This will allow the sauce to heat up along with the other ingredients, ensuring a cohesive and delicious meal.
