This festive mashed potato and celeriac mash is a simple, joyful side that lifts any roast. It’s the kind of cooking, easy recipes that delivers big flavor with very little fuss. A balance of creamy potato and the celery-like freshness of celeriac makes this an ideal companion for Thanksgiving or Christmas dinners.
Why this mash works
The mash pairs fluffy potatoes with earthy, slightly peppery celeriac. When roasted or caramelized, celeriac develops deep, nutty notes, but gently boiled and mashed with butter and cream keeps it bright and comforting. A small bunch of thyme simmered in the cooking water subtly infuses the vegetables for more depth.
Ingredients
- 1.5 kg potatoes — peeled and cut into roughly 1-inch chunks
- 1.5 kg celeriac — scrubbed, peeled, and cut into 1-inch chunks
- 1 small bunch of thyme (optional, to infuse the cooking water)
- 50–100 g butter
- 1 tbsp olive oil
- 100–150 ml double cream (or to taste)
- Salt and freshly ground black pepper
Method
- Place equal-sized chunks of potato and celeriac into a large pan and cover with cold water. Add the thyme bundle to the water to infuse the veg as they cook.
- Bring to a gentle boil and simmer for 12–13 minutes, or until both vegetables are tender when pierced with a knife.
- Drain carefully, remove the thyme, and let the veg sit for a minute to steam off excess moisture.
- Return to the pan or a warm bowl. Add the butter and olive oil first, then pour in the cream. Mash to the desired consistency and season to taste with salt and pepper.
- Transfer to a heatproof serving bowl and smooth the surface. To keep warm, pour 2–3 inches of water into a wider pan, set the bowl inside, and cover with a lid to create gentle steam. Check occasionally so the water does not boil dry.
Celariac is an incredible vegetable.
Tips for perfect mash
- Size matters — cut all pieces to the same size so they cook evenly.
- Infuse the water — simmering thyme in the cooking water adds subtle aromatic flavor without overpowering.
- Don’t overwork — mash until just smooth; overmixing makes potatoes gluey.
- Keep warm — the steaming bowl trick keeps the mash at serving temperature during busy holiday service. This is a simple but brilliant trick for festive gatherings and great for anyone exploring cooking, easy recipes.
Serving and storage notes
Serve piping hot alongside roast meats or glazed vegetables. Leftovers keep in the refrigerator for 2–3 days. Reheat gently on the stove with a splash of cream to restore silkiness. This recipe is a lovely example of straightforward holiday fare and suits anyone looking for reliable cooking, easy recipes.
Final thoughts
This potato and celeriac mash is unfussy, show-stopping, and comforting. It proves that small tricks — a herb in the water, a knob of butter, and a gentle steaming method to keep it warm — can make an everyday side feel festive. Try it for the next roast and enjoy how a humble root vegetable transforms the plate.
