BHA & BHT Free Classic Cauliflower Gratin
Bubbling, golden, and deeply comforting, this cauliflower gratin is the kind of dish that turns a humble vegetable into something genuinely showstopping. A silky homemade béchamel made from butter, flour, and whole milk wraps every floret in rich, nutmeg-scented sauce, while melted Gruyère adds that signature savory depth. The buttered panko topping bakes into a shatteringly crisp crust that contrasts beautifully with the tender cauliflower underneath. For anyone avoiding synthetic preservatives like BHA and BHT, packaged gratins and store-bought cheese sauces can be a minefield — this recipe sidesteps all of that by building everything from scratch with whole, recognizable ingredients. There's no need to squint at a label when you're the one whisking the sauce and grating the cheese. A final scatter of fresh parsley brightens the whole thing just before it hits the table, making it as pretty as it is satisfying.

Instructions

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.
