This mash is pure comfort: creamy, smooth and deeply savoury thanks to slow-roasted garlic. The cloves become sweet and mellow in the oven, blending effortlessly into the potatoes and giving them a gentle festive richness without overwhelming the palate. It’s a perfect partner to the glazed celeriac and gravy.
The mash reheats beautifully and is ideal for preparing ahead, making it a reliable Christmas Day side that won’t add any stress to your schedule.
