Lupin Free Classic Béchamel
Silky, rich, and endlessly versatile, this classic white sauce is the kind of kitchen staple that elevates everything it touches — from lasagna layers to gratins to a simple croque monsieur. The ingredient list is refreshingly short: butter, flour, whole milk, and a whisper of nutmeg, salt, and white pepper. That simplicity is actually great news for anyone navigating lupin avoidance, since many store-bought béchamels and pre-made sauce mixes can sneak in lupin flour as a thickener or protein booster. Here, plain all-purpose flour does the job the traditional way, so there's no guesswork about what's actually in your sauce. The technique is straightforward — a quick roux cooked until pale and nutty, then milk added gradually while you whisk — and the result is a smooth, glossy sauce with real depth of flavor. That final pinch of nutmeg is the secret move that makes it taste genuinely restaurant-quality. Make it fresh and use it right away, or press plastic wrap directly onto the surface to keep it silky until you're ready to pour.
