Onions in Pakistani Cooking: Soft, Golden, Brown or Birista?
How to cook onions for Pakistani curries: the four stages (soft, golden, brown and birista), which dishes need which, how long each takes, and how to avoid burning them.
Almost every Pakistani curry starts with onions in hot oil, and how far you cook them changes the whole dish. Pale, soft onions give a light, sweet curry. Deep brown onions give a dark, rich gravy. Crisp fried onions, birista, are the backbone of biryani and qorma. Recipes say “fry until golden” or “until brown”, and knowing exactly what that means is one of the most useful skills in desi cooking.
The four stages
1. Soft (translucent). The onions lose their raw crunch and turn see-through, with no colour. It takes about 3–5 minutes on medium heat. Used in lighter vegetable dishes like aloo gobi, and in some white karahis where colour isn’t wanted.
2. Golden. Light gold all over, with a sweet smell. It takes 8–10 minutes. This is the stage for most everyday salans, daals and chana masala. It gives a balanced, medium-coloured gravy.
3. Brown. Deep golden-brown, with darker edges. It takes 12–15 minutes. Used in richer meat dishes like aloo gosht and many karahis and qormas. It gives a darker gravy with a deeper, slightly caramelised flavour.
4. Birista. Thinly sliced onions fried in plenty of oil until deep brown and crisp, then lifted out. It takes 15–20 minutes. This is , used for biryani, qorma, haleem and garnishes.
Slice or chop?
Slice onions into thin half-moons for birista, qorma and biryani, where they’re fried until crisp or ground into a paste. Chop them finely for salan, daal and keema, where they melt into the masala. For the smoothest gravies, some cooks grate or blend the onions.
Whatever you choose, cut them evenly. Pieces of different sizes cook at different speeds, so some burn while others stay raw.
How to brown onions without burning them
- Use enough oil. Onions need fat to brown evenly. Too little oil and they stick and scorch in patches.
- Start on medium-high, finish on medium. High heat at the start drives off water quickly; lower heat at the end gives you control as they darken.
- Stir regularly, more often as they darken. Onions change slowly at first, then very fast at the end.
- Add a pinch of salt at the start. It draws out moisture and helps them cook evenly.
- Watch the edges. Onions brown first at the edges of the pan; keep moving them.
- Take them off a shade early. They keep cooking in the hot oil for several seconds after you turn the heat off.
Making birista
Birista is worth making in a big batch. Slice 4–5 onions thinly and evenly. Heat about a cup of oil in a karahi. Fry the onions on medium-high heat, stirring, until they shrink and turn golden, then lower the heat and keep frying, stirring constantly, until deep brown. Lift them out with a slotted spoon onto a plate lined with paper; they crisp as they cool.
Stored in an airtight jar, birista keeps for a week in the fridge or two months in the freezer. Crush it into marinades, layer it into biryani or sprinkle it over daal and haleem. The leftover onion-flavoured oil is excellent for cooking the next curry.
When onions go wrong
Bitter, burnt onions: start again. Burnt onions make the whole curry bitter, and no amount of spice will fix it.
Pale, sweet curry: the onions weren’t cooked far enough. Next time, give them a few more minutes.
Onions sticking and catching: add a splash of water, scrape the bottom, and keep going.
Getting onions right is the first half of a good curry. The second half is the , which we cover in our bhunai guide.
