What temperature should oil be for deep frying?

Most foods fry best between 350 °F and 375 °F (175–190 °C). Thick or bone-in foods such as fried chicken go lower (325–350 °F) so the inside cooks before the crust darkens; quick items such as calamari or the second fry of French fries go higher (375–385 °F). Below about 325 °F food absorbs more oil and turns greasy.

What temperature do you fry chicken at?

Fry bone-in chicken at 325–350 °F (163–177 °C) for about 12–15 minutes, and boneless tenders or nuggets at 350–375 °F for 4–6 minutes. The oil temperature drops when the chicken goes in, so heat the oil about 10–15 °F above the target. The chicken is safe when the thickest part reaches 165 °F (74 °C), the USDA safe minimum for poultry.

How hot should oil be for French fries?

Use two stages: blanch at 325 °F (163 °C) for 4–6 minutes until soft but pale, rest the fries, then finish at 375 °F (190 °C) for 2–3 minutes until golden and crisp. Frozen par-fried fries need only the hot stage.

What is the smoke point and which oils are best for deep frying?

The smoke point is the temperature at which oil starts to break down and smoke, giving off-flavours and irritating fumes. Use a refined oil with a smoke point well above your frying temperature: refined peanut (about 450 °F), canola (400–446 °F), corn, soybean, sunflower, safflower, rice bran or refined avocado. Unrefined oils such as unrefined peanut (about 320 °F) or unrefined sunflower (about 225 °F) are not suitable. Each reuse lowers the smoke point.

Can you deep fry with olive oil?

Yes. Extra-virgin olive oil smokes at about 374–405 °F (190–207 °C) depending on quality, and refined or "light" olive oil at about 390–470 °F. Both are above the usual 350–375 °F frying range, but extra-virgin olive oil is expensive in deep-fry quantities and its flavour fades with heat.

How much oil do I need for deep frying?

Plan on 2–3 inches (5–8 cm) of oil so food can float, while keeping the oil no more than halfway up the pot so it cannot bubble over. A 10-inch (25 cm) Dutch oven needs about 4 quarts (3.9 L) for 3 inches of oil. For a whole turkey, find the fill line first: put the thawed bird in the empty pot, cover it with water, remove the bird and mark the water level.

How long does it take to deep fry a turkey?

Heat the oil to 350 °F (177 °C) and allow about 3–4 minutes per pound, so a 12 lb turkey takes roughly 36–48 minutes. The turkey must be completely thawed and dry, and it is done when the thigh, wing and thickest part of the breast all reach 165 °F (74 °C). Fry outdoors, away from buildings, and never leave the fryer unattended.

How do I know the oil is hot enough without a thermometer?

A wooden spoon handle or chopstick placed in the oil should bubble steadily at around 350 °F, and a 1-inch bread cube should brown in about 60 seconds. These tests are rough. A clip-on deep-fry or candy thermometer is the only reliable way to hold the right temperature between batches.

Can I reuse frying oil?

Yes, a few times, if it was not overheated. Let it cool, strain it through a fine sieve or cheesecloth, and store it covered in a cool, dark place. Discard it when it darkens, smells rancid, foams or starts to smoke at normal frying temperature. Oil used for fish is best kept for fish.

Deep Fry Oil Temp Guide

Most foods fry at 350–375 °F (175–190 °C). Look up the exact oil temperature, fry time and safe internal temperature for 24 foods, check your thermometer reading against your oil's smoke point, and work out how much oil your pot needs.

Smoke points vary by brand, refining, freshness and free fatty acid content, and fall each time the oil is reused, so treat them as approximate. Refined and unrefined values are typical published figures; the USDA FSIS column is the agency's single value per oil. Choose an oil whose smoke point is well above your frying temperature.

Summary

This guide lists the oil temperature, typical fry time and doneness check for 24 deep-fried foods, from French fries (325 °F blanch, 375 °F finish) to fried chicken (325–350 °F to an internal 165 °F) and whole turkey (350 °F, about 3–4 minutes per pound). Switch between °F and °C or filter by food. The oil checker compares a thermometer reading with the target range for a food and with the smoke point of your oil. The smoke-point table separates refined and unrefined oils and shows the USDA FSIS figures. The pot calculator converts pot diameter and oil depth into quarts and litres and warns when the pot is too full.

How it works

Choose °F or °C and browse the chart, or type a food name to filter it.
Read the oil temperature, typical fry time and doneness check. Meat, poultry and fish must reach the USDA safe minimum internal temperature, so check them with an instant-read thermometer.
In the oil checker, pick the food and your oil and enter the thermometer reading to see whether to heat up, wait or add food.
In the pot calculator, enter the pot size, the oil depth you want and the pot height to get the oil volume and a fill-level check.
Use the smoke-point table to choose a refined, high-smoke-point oil for deep frying.
