Brussels sprouts gratin is what happens when comfort meets intention. Tender sprouts baked in a creamy sauce turn a sometimes-overlooked vegetable into something rich and inviting. It’s the kind of dish that changes minds at the table not by convincing, but by tasting good.
This gratin works because it respects the sprout. Roasting or blanching first softens the bite, while the oven brings everything together into a golden, bubbling finish. It’s familiar food, reimagined gently, without losing its grounding feel.
In the Let’s Veg lifestyle, Brussels sprouts gratin represents balance. Vegetables can be nourishing and indulgent at the same time. There’s room for comfort especially when vegetables remain the heart of the dish.
