How To Make Lasagna White Sauce Recipe?
- Melt the Butter: In a medium-sized pan, melt the butter over medium heat.
- Add the Flour: Once the butter has melted, add the flour and whisk them together.
- Cook the Flour: Whisk for a few minutes while it bubbles, to cook out the raw flour taste.
- Add the Milk: Gradually pour in the milk, whisking continuously until the mixture becomes smooth after each addition.
- Thicken the Sauce: Continue stirring until the sauce reaches a thick, glossy consistency, but not too stiff.
- Season: Season with salt, pepper, and a pinch of nutmeg, if desired.

Recipe Tips:
- Whisk Constantly: Stir the sauce continuously while adding milk to avoid lumps and ensure a smooth texture.
- Adjust Consistency: If the sauce gets too thick, add a little more milk to loosen it up until you reach the perfect consistency.
- Cook the Flour Properly: Don’t skip cooking the flour for a few minutes to avoid a raw taste in the sauce.
- Season Well: Taste the sauce and adjust the seasoning with more salt, pepper, or nutmeg for extra flavor.
- Reheat Gently: When reheating, do so on low heat and stir frequently to prevent it from burning or becoming too thick.

- Refrigerate: Cool the leftover sauce to room temperature, then store it in an airtight container in the fridge for up to 2-3 days.
- Freeze: To freeze, cool the sauce, then store it in a freezer-safe container for up to 1 month.
