Deep Frying Oil Temperature: Crisp Pakoras That Aren’t Oily
Soggy, oily pakoras almost always mean one thing: the oil was too cold. Deep frying works best at about 170 to 180 °C, in small batches, with a proper drain afterwards. Get those three right and the pakora cooks fast, seals its outside, and soaks up less oil than the greasy ones from a crowded kadhai.
Before you start
- Oil heat: 170 to 180 °C for pakoras, samosas, fries.
- Without a thermometer: a drop of batter sinks, then rises within 2 to 3 seconds with steady bubbles.
- Batch: cover no more than half the oil surface.
- Drain: on a wire rack or a steel sieve, not a pile of newspaper.
- Safety: kadhai no more than half full; water never goes near hot oil.

Why cold oil makes greasy food
Batter is full of water. Drop it into properly hot oil and that water turns to steam at once, bursting outward through the soft batter before the oil has a chance to creep in. The steam rushes outward, which is why you see those lively bubbles. While steam pushes out, oil can’t easily get in.
At the same time, the outside dries into a crisp crust. Crunch.
In cool oil, say 140 °C? Slow steam. The pakora sits there pale, slowly cooking, while oil seeps into the batter the whole time, so what you lift out with the jhara is heavy, pale, limp and wet with oil that no amount of tapping on the rim will shake loose. Most oil actually enters food as it cools after frying, drawn into the tiny spaces the steam left, which is why draining right away matters too.
Hot oil fries. Warm oil soaks.
How to test oil temperature without a thermometer
A kitchen thermometer (a probe or a clip on one) is cheap and removes the guesswork, which is worth it if you fry often, but plenty of good cooks have never owned one and rely on the batter drop, the spoon handle and their own eyes instead. Without one, these checks work well together.
| Test | Too cold | Right (170 to 180 °C) | Too hot |
|---|---|---|---|
| Drop of batter | Sinks, stays down | Sinks, rises in 2 to 3 s | Rises at once, browns fast |
| Wooden spoon handle | Few lazy bubbles | Steady stream of bubbles | Fierce bubbling |
| Bread cube (2 cm) | Pale after 1 minute | Golden in about 60 s | Brown in 20 s |
| Oil surface | Still | Shimmering | Smoking |
Smoke means stop. Turn off the flame and let it cool before carrying on. Smoke points and reuse are in cooking oil reuse and smoke point.
Step by step: crisp pakoras that aren’t oily
- Batter: 1 cup besan, about half a cup cold water added slowly, half a teaspoon salt, half a teaspoon ajwain, chilli to taste. It should coat a spoon thickly and drop in a slow ribbon. A pinch of rice flour (1 to 2 tablespoons) adds crunch.
- Dry the vegetables: pat onion, potato or palak dry with a cloth. Wet vegetables spit and water down the batter.
- Salt last for onion pakoras: salt pulls water out of onion within minutes, so mix just before frying.
- Oil depth: about 5 to 7 cm in a heavy kadhai, filled to no more than half its depth, on medium high.
- Test, then fry in batches: once a batter drop rises in 2 to 3 seconds, add pakoras so they cover no more than half the surface. Too many at once drops the temperature sharply.
- Adjust the flame: turn it up a little right after adding a batch, then back to medium when the bubbling recovers.
- Fry and turn: 3 to 4 minutes, turning once or twice, until deep golden and the bubbling slows. Slowing bubbles mean most of the water has gone.
- Drain on a rack: lift with a jhara, tap once on the rim, and set on a wire rack or steel sieve over a plate. Kitchen paper works for a minute; stacked pakoras on newspaper steam and go soft (and printing ink doesn’t belong on food).
- Let the oil recover for 30 to 60 seconds before the next batch.
Double fry for extra crunch
For aloo fries or pakoras for guests, fry once at about 160 °C until just cooked and pale, rest on a rack for 10 minutes, then fry again at 180 °C for a minute until crisp. The first fry cooks the inside, the second sets the crust. It’s the same idea street vendors use.
Which oil and how much absorbs
Any oil that handles steady high heat works: sunflower, canola, corn, rice bran, groundnut or refined mustard oil. Unrefined oils such as kachi ghani mustard and extra virgin olive oil smoke earlier and have strong flavours, so they suit a quick tadka or a shallow fry far better than a long session of samosas, fries and pakoras for a houseful of guests on a rainy evening. Desi ghee can fry but browns quickly. Pricey too.
How much oil ends up in the food depends mainly on temperature, surface area and draining, not the brand, the price or whatever the label on the bottle promises about “low absorption”. Thin, lacy pakoras have more surface than chunky ones, so they carry more oil. Fried is fried. Pakoras with Ramadan iftar or a rainy day chai are fine; daily deep frying adds a lot of fat and calories. For a lighter crunch, see air fryer versus oven versus dehydrator.
Myth: a pinch of salt in the oil stops it soaking in
Salt doesn’t dissolve in oil, so it can’t change how much oil the food takes up. It sinks. Adding a spoon of hot oil into the batter (“mohan”) makes samosa pastry flaky and pakoras a little lighter, but it doesn’t stop cool oil from soaking in. The only real fixes are the heat and the batch size.
Another one: “soggy pakoras mean bad besan”. Usually it’s cold oil, a thin batter, or both, and fixing those two costs nothing but a minute of patience while the kadhai heats up properly before the first spoonful goes in.
Hot oil burns deeply. Keep children out of the kitchen when the kadhai is on, turn the handle inwards, and never leave hot oil alone. If oil catches fire, turn off the gas and slide a lid or damp towel over the pan; never pour water on it and never carry the pan. For a skin burn, hold it under cool running water for about 20 minutes and don’t apply butter, toothpaste or ice; see kitchen burn first aid. Get medical help for burns larger than the palm, on the face, hands or genitals, burns on a child, or any burn that looks white or charred.

Deep frying questions
What temperature should oil be for pakoras?
About 170 to 180 °C. That’s hot enough to crisp the outside quickly while the inside cooks through in 3 to 4 minutes.
Why are pakoras oily?
Usually because the oil was too cold or the kadhai was overcrowded; both let the batter sit and soak instead of sealing; draining on a rack also helps a lot.
How do you know oil is ready without a thermometer?
Drop in a little batter; if it sinks and rises within 2 to 3 seconds with a lively fizz, it’s ready; a wooden spoon handle should show a steady stream of small bubbles.
How to make pakoras crispy?
Use thick besan batter with a little rice flour, dry the vegetables, fry at 170 to 180 °C in small batches, and drain on a rack. Double frying adds more crunch.
Why do pakoras break in oil?
The batter is too thin or the vegetables are wet. Add a spoon of besan to thicken it and pat vegetables dry before mixing.
Why are pakoras brown outside but raw inside?
The oil is too hot. Lower the flame slightly and make pieces smaller so the middle cooks before the outside darkens.
How much oil does deep fried food absorb?
It varies with the food, the temperature and the draining; thin, crumbly items absorb more than chunky ones; hot oil and a good drain keep it lower.
Can you deep fry in olive oil?
Refined or light olive oil works well. Extra virgin can be used at moderate frying heat, but it costs more and has a strong taste.
How many times can frying oil be reused?
A few times if it’s strained and stays clean, less after frying fish or heavily spiced food. Throw it away once it’s dark, thick, foamy or smells sharp.
What to do if hot oil splashes on skin?
Hold the area under cool running water for about 20 minutes and remove rings or tight clothing nearby. Cover loosely with cling film or a clean cloth, and see a doctor for large, deep or facial burns.
