Citric Acid Free Classic Cauliflower Gratin
Bubbling, golden-topped, and deeply comforting, this cauliflower gratin is the kind of dish that turns a humble vegetable into something genuinely showstopping. A silky béchamel made from butter, flour, and whole milk wraps every floret in richness, while nutty Gruyère melts through the sauce and crisps up beautifully on top alongside buttered panko breadcrumbs. For anyone navigating a citric acid sensitivity, this recipe is a natural fit — every ingredient is straightforward, with no citrus-derived additives, preservatives, or acidic flavor enhancers hiding in the list. Cauliflower gratins can sometimes call for a squeeze of lemon or a splash of white wine, but this version gets all its depth from the toasted roux, warm nutmeg, and generous cheese without any of those triggers. The technique is approachable too: blanch the cauliflower until just tender, build the sauce, layer everything in a baking dish, and let the oven do the rest. A scatter of fresh parsley at the end adds a little color and freshness without introducing anything problematic. It's the kind of side dish that earns a permanent spot in your rotation.

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.
