Béchamel is one of those foundational sauces that makes everything it touches taste more luxurious — think lasagna, moussaka, croque monsieur, or a bubbling gratin fresh from the oven. This version is built from just six pantry staples: butter, flour, whole milk, salt, white pepper, and a whisper of nutmeg. The technique is straightforward but satisfying, starting with a quick roux that cooks off any raw flour taste before the milk is streamed in gradually for a silky, lump-free result. For anyone navigating tree nut allergies or sensitivities, this sauce is a genuinely safe comfort — no hidden nut-based thickeners, no specialty swaps required, just clean, classic ingredients doing exactly what they're supposed to do. The nutmeg here adds warmth and depth without any cross-contamination concern, since it's botanically unrelated to tree nuts and used in a small, carefully measured amount. Once you've got this sauce in your repertoire, you'll find yourself reaching for it constantly — it keeps beautifully under plastic wrap pressed right to the surface, ready to finish whatever dish you have in mind.

Melt the butter in a medium saucepan over medium heat until foamy but not browned.
Add the flour all at once and whisk constantly for 1 to 2 minutes, until the mixture turns a pale straw color and smells faintly nutty — this cooks out the raw flour taste.
