Roast potatoes are a classic accompaniment to roast meats, but these Goose Fat Roast Potatoes are so good they can easily steal the show. The secret to that addictive crunch and pillowy interior is the combination of the right potato, careful preparation and, crucially, goose fat.

Goose Fat Roast Potatoes

The ideal roast potato has a crisp, golden crust and a light, fluffy centre. Goose fat helps create that contrast: it has a high smoke point and imparts a rich, savory flavour while allowing the exterior to blister and crisp quickly.

Goose fat is widely available during the holidays, and duck fat is an excellent substitute. If you roast a goose or duck at home, strain and reserve the rendered fat—use a fine sieve or muslin to remove any browned solids before storing.

What can I use instead of Goose Fat?

For a vegetarian option, use ghee (clarified butter), which tolerates high heat. For vegan/vegetarian diets, a neutral vegetable oil with a high smoke point works well—avoid regular olive oil, which smokes at lower temperatures.

Golden Rules for Crispy Roast Potatoes

Alongside goose fat, a few technique points ensure consistent results. Follow these golden rules for the best roasties:

Choose the right potatoes

Use floury varieties such as Maris Piper, King Edward or Russet. These break down slightly on cooking and become fluffy inside—new (waxy) potatoes are not suitable for roasties or mash. For the crispiest results, peel your potatoes for this recipe.

The right size (and shape)

Cut potatoes into uniform medium-sized chunks so they cook evenly. A handy method is to trim each end at a slant and cut the potato into three or four pieces, leaving a triangular centre piece for good surface area. Avoid cutting them too small.

Parboil your spuds

Parboiling softens the outer layer without finishing the potato. This reduces oven time and increases the surface that will crisp. Simmer until the outside is tender but the centre is still firm—usually 7–10 minutes depending on size.

Rough Them up!

After draining, toss the potatoes in a colander so the edges break apart slightly. Dust with fine semolina or a little flour and shake again. Those rough edges create extra crunchy bits when roasted in hot fat.

Leave them to steam dry

Let the potatoes steam dry a few minutes after parboiling before adding them to the roasting tin. This helps remove surface moisture so the fat can crisp the exterior instead of steaming it.

Keep your distance

Give each piece some space on the tray. Overcrowding traps steam and prevents crisping—spread the potatoes so each one has room to brown.

How to make Goose Fat Roast Potatoes

Full measurements and a printable recipe card are available in the recipe section below. Read the steps and watch the video before you begin for best results.

Preheat the oven to 220°C (430°F) or 200°C (400°F) for fan ovens. Put the goose fat into a large roasting tin and place it in the oven to get very hot—this may produce some smoke, so ventilate the kitchen if needed.

Peel the potatoes and cut them into medium even chunks. Place them in a saucepan, cover with cold water, add 1 tsp salt and bring to the boil. Simmer for 7–10 minutes until the edges are tender but the centre still feels firm.

Drain the potatoes (do not rinse). Toss them in a colander to rough up the edges, then sprinkle with 2 tbsp fine semolina or 1 tbsp flour and season with coarse salt and black pepper. Leave to steam dry for at least five minutes.

Carefully remove the hot roasting tin from the oven with oven mitts. Using tongs, place each potato piece in the fat—do not tip the colander into the tin to avoid dangerous splatters. Turn pieces so they are coated in the hot fat; they should sizzle on contact.

Adding parboiled potatoes to roasting tray with hot goose fat

Roast for 15 minutes, then turn the potatoes to brown evenly and roast for a further 15 minutes. Depending on size and parboil time, they are often done in about 30 minutes. If needed, roast another 10–15 minutes until the crust is deep golden and the interior is soft and fluffy.

Transfer the potatoes to a platter and finish with fresh rosemary and a little extra salt if desired.

Top tips for goose fat roasties

  • Handle potatoes with tongs. Never tip raw potatoes into hot fat—this causes dangerous splattering.
  • Test the fat. Drop one potato in to check: it should sizzle loudly when the fat is hot enough.
  • Add herbs after roasting. Fresh herbs or garlic will burn at the high roasting temperature; sprinkle them on once the potatoes are out of the oven.
  • Save and reuse the fat. Strain leftover fat through a fine sieve or muslin, cool and store in a jar in the fridge for future roasting.
  • Scale sensibly. This recipe serves about four. If increasing quantities, use extra roasting tins to avoid overcrowding.
  • Reheat well. Leftovers revive beautifully in an air fryer or hot oven.
