Walnut Free Classic Cauliflower Gratin
Creamy, bubbling, and crowned with a shatteringly crisp breadcrumb crust, this cauliflower gratin is the kind of side dish that quietly steals the show at any dinner table. Tender blanched florets get nestled into a silky Gruyère béchamel — the kind of sauce that takes only a few minutes of whisking but tastes like you really know what you're doing. The combination of nutty melted cheese, a whisper of freshly grated nutmeg, and that buttery panko topping creates layers of flavor and texture that feel genuinely indulgent. For anyone navigating tree nut concerns, this recipe is naturally free of walnuts at every step, with no substitutions or workarounds needed — just straightforward, wholesome ingredients you can feel confident about. Store-bought gratins and packaged sides can be a minefield of unexpected add-ins, so making this from scratch puts you fully in control. It comes together in one baking dish and emerges from the oven golden, fragrant, and ready to rest just long enough for you to resist digging in immediately. A scatter of fresh parsley at the end adds a bright finish that makes the whole thing look as good as it tastes.

Preheat the oven to 400°F (205°C). Bring a large pot of generously salted water to a boil. Add the cauliflower florets and cook for 4 minutes, until just barely tender when pierced with a knife but still holding their shape. Drain in a colander and let steam-dry for 2 minutes.

Melt 3 tbsp butter in a medium saucepan over medium heat. Add the flour and whisk constantly for 1 to 2 minutes, until the mixture turns a pale golden color and smells faintly nutty.
