Instructions

1
Peel the potatoes and place them in a bowl of water to prevent browning.
2
In a saucepan, pour in the Guinness and bring to a simmer. Reduce the liquid by half.
3
Add the vegetable stock to the reduced Guinness.
4
Add the peeled potatoes to the pot, cover, and boil for about 10 minutes until par-cooked.
5
Drain the potatoes and allow them to cool down completely.
6
Once cooled, grate the potatoes into a large mixing bowl.
7
To the grated potatoes, add the onion powder, salt, and cornflour.
8
Mix everything together with your hands until well combined.
9
Shape the potato mixture into oval patties. You can use a ring mold for a uniform shape.
10
Place the shaped hash browns on a tray lined with aluminum foil and freeze for 20 minutes to help them hold their shape.
11
Heat a generous amount of vegetable oil in a frying pan over medium-high heat.
12
Carefully place the frozen hash browns into the hot oil and fry for about 3 minutes per side, until deep golden brown and crispy.
13
Remove from the pan, drain on a wire rack or paper towel, and serve immediately.

Tips & Notes

Pro tips

Freeze patties for at least 4 hours before frying—cold, firm patties develop a crispier crust and hold together better.
Use medium-high heat and ensure the oil is hot before adding patties; this creates the golden crust without burning the exterior while the inside cooks through.
Don't skip the cornflour—it acts as a binder and helps create that signature crispy exterior texture.
Test doneness by gently pressing a patty with a spatula; it should feel firm and not fall apart.

Substitutions

Guinness → dark ale or beef stock (loses malty flavor but maintains structure)
Maris Piper potatoes → Yukon Gold or other waxy potatoes (avoid floury varieties)
Cornflour → potato starch (1:1 ratio, similar binding effect)

Storage & make-ahead

Store cooked patties in an airtight container in the refrigerator for up to 3 days; reheat in a 375°F oven for 8–10 minutes until crispy, or pan-fry over medium heat for 2–3 minutes per side.

Equipment

large pot (for boiling potatoes) · frying pan or skillet (cast iron recommended for even browning)

Common Questions

Why boil hash browns in Guinness?

Boiling in Guinness infuses the potatoes with a subtle malty depth and richness that sets these apart from standard hash browns. The stock adds savory flavor while the cooking process breaks down the potatoes slightly for better binding.

Can I make these ahead of time?

Yes. Form and freeze the patties for at least 4 hours or overnight. Freezing firms them up so they hold their shape and develop a crispier exterior when fried.

What potatoes work best?

Maris Piper potatoes are ideal because they have a creamy texture and hold together well. Other waxy potatoes like Yukon Gold will also work; avoid floury varieties.

How do I know when they're done frying?

The patties should be deep golden brown and crispy on both sides, about 4–5 minutes per side over medium-high heat. Pierce one with a fork—the interior should be soft and hot throughout.

Can I use a non-alcoholic substitute for Guinness?

Yes. Replace Guinness with an equal amount of vegetable or beef stock, though you'll lose the malty flavor complexity. A dark ale or stout would be the closest alternative.
