Peanut Oil
10.0best for stir frySlight nutty flavor, great for deep frying
Vegetable Oil provides neutral fat in Stir Fry, keeping the sauce and coating moist without adding strong flavor. Refined blends marketed as vegetable oil typically smoke at around 400–450°F, which comfortably withstands wok cooking; a substitute needs a comparable refined smoke point so it doesn't break down before the vegetables are fully cooked.
Slight nutty flavor, great for deep frying
Peanut oil is the gold-standard stir-fry oil — 1:1 by volume with a 450°F smoke point and a subtle nutty aroma that defines classic Cantonese wok hei. Preheat the wok 2 minutes until a water drop flashes in under a second, swirl 2 tablespoons up the sides, then add ginger and garlic for 15 seconds before protein.
Neutral flavor, same smoke point
Corn oil swaps 1:1 by tablespoon with a 450°F smoke point that handles wok heat cleanly. Its neutral flavor lets aromatics and sauces lead. Preheat the wok 2 minutes, swirl oil up the sides, and add aromatics for 15 seconds — work in 1-cup batches to keep the high-heat sizzle that creates the char.
All-purpose neutral oil
Safflower oil is 1:1 by tablespoon with a 510°F smoke point — the highest in this lineup. It laughs at wok temperatures and its perfect neutrality lets ginger and garlic aromatics dominate without competition. Preheat the wok 2 minutes, swirl oil up the sides, and sear protein 90 seconds before adding vegetables.
Most direct swap, nearly identical
Canola oil swaps 1:1 by volume with a 400°F smoke point that sits at the edge of wok territory. Drop the heat slightly from a roaring flame to medium-high and work in smaller 3/4-cup batches to keep the sizzle alive. Its clean neutral flavor lets ginger, garlic, and finishing sauces define the dish.
Neutral flavor, similar smoke point
Sunflower oil is 1:1 by volume with a 440°F smoke point that handles the wok's high heat comfortably. Preheat the empty wok 2 minutes, swirl 2 tablespoons up the sides, add ginger and garlic for a quick sizzle, then protein in batches. The neutral flavor lets wok hei char and finishing sauces dominate.
Higher smoke point, works for frying and baking
Typically soybean-based already; direct swap in frying, baking, and dressings with no flavor change
Neutral and widely available
Widely available neutral swap
Use melted; adds slight coconut flavor
Neutral flavor, best for baking and frying
Use light/refined, not toasted for cooking
High smoke point and nutty; use 3/4 cup per cup oil, excellent for frying and sauteing
In baking use 7/8 cup, adds rich flavor
Clarified butter, high smoke point for frying
Solid fat; cream into sugar for cookies, melted for quick breads, adds slight richness
Use 3/4 cup oil per cup, works in quick breads
Use slightly less, works for frying but not pastry
Liquid swap for cooking uses
Vegetable oil in stir-fry is chosen for its 400°F+ smoke point, not its flavor — the whole point is to hit the wok at high heat so aromatics like ginger and garlic sizzle instantly and sear proteins with a crisp char in under 60 seconds. Unlike pasta, where oil is a medium-heat emulsifier for the sauce, stir-fry oil is a thermal transfer medium: the wok must be ripping hot (preheat empty for 2 minutes until a water drop evaporates in under 1 second), then 2 tablespoons oil goes in and is swirled up the sides before any food lands.
Add aromatics for 15 seconds, protein for 90 seconds tossing constantly, then hard vegetables for 2 minutes and soft ones for 60 more. The flame and smoke point combination creates wok hei — that charred, breath-of-the-wok flavor you can't replicate at lower temperatures.
Work in 1-cup batches to keep the wok hot; overcrowding drops the temperature 50°F and steams food instead of searing. Finish with sauce added in the final 20 seconds so sugars don't burn.
Preheat the empty wok for 2 minutes until a water drop evaporates in under 1 second before adding oil — a cold wok steams food instead of searing it and ruins the wok hei char.
Don't overcrowd the wok; work in 1-cup batches because overcrowding drops the temperature 50°F and kills the high-heat sizzle that defines stir-fry.
Skip extra-virgin olive oil or butter — they smoke below 400°F, and the smoke point failure creates acrid, burnt aromatics instead of the clean char you want.
Add sauce in the final 20 seconds, not at the start; sugars in stir-fry sauces burn on the flame within 30 seconds and turn bitter.
Keep aromatics like ginger and garlic in the wok for only 15 seconds before protein goes in; longer contact with the high heat burns them to bitterness.
