How to Sauté (Pan Temperature, Fat, and Timing)

To sauté, heat a wide pan until it is hot, add a thin film of fat, and cook small, dry, evenly cut pieces of food in a single layer, tossing or stirring often until browned and just cooked. The word comes from the French sauter, "to jump," after the way food flips in the pan.

The science: keep the pan hotter than 100 °C

Sautéing is a race between two processes. Food is mostly water, and water cannot get hotter than 100 °C / 212 °F at sea level while it is liquid. Browning reactions like the Maillard reaction speed up dramatically above about 140 °C / 285 °F. So the surface of the food has to dry out before it can brown.

A good sauté keeps the pan hot enough that moisture leaving the food evaporates instantly. When the pan is too cool or too crowded, released water pools, the temperature drops toward 100 °C, and the food simmers in its own juices. You get grey mushrooms and limp peppers instead of golden ones.

Three things keep the pan hot:

• Preheat: a properly preheated pan stores heat to absorb the shock of cold food.
• Room: food covers no more than about two thirds to three quarters of the pan's surface, leaving space for steam to escape.
• Dry food: pat ingredients dry. Every drop of surface water costs energy to evaporate.

Choosing the pan and fat

A wide pan with sloped or straight sides and a heavy base works best. Stainless steel and carbon steel build fond, the browned bits that make a great pan sauce. Nonstick is fine for eggs and delicate items but browns less and should not be heated empty on high.

Smoke points vary by brand and refinement. See smoke point for more.

Steps

1. Cut ingredients into small, even pieces and pat them dry. Pieces about 1 to 2 cm (1/2 to 3/4 in) cook through in the same time they take to brown.
2. Preheat a wide pan over medium-high heat for 1 to 2 minutes. On stainless steel, a drop of water should skate across the surface as a bead rather than sizzle away. That is the Leidenfrost effect, and it tells you the pan is properly hot.
3. Add a thin film of fat and heat until it shimmers. About 1 to 2 tablespoons (15 to 30 mL) for a 30 cm (12 in) pan. Shimmering oil flows like water and shows faint ripples; smoking oil is too hot.
4. Add the food in a single layer without crowding. You should hear a lively sizzle. If it goes quiet, the pan was too cool or too full. Cook in batches if needed.
5. Let it sit briefly to brown, then toss or stir. Leave the food alone for 30 to 90 seconds so a browned surface can form, then toss with a flick of the wrist or stir with a spatula. Repeat.
6. Season and adjust the heat as it cooks. Salt draws moisture out, so many cooks salt vegetables partway through rather than at the start, especially mushrooms. Lower the heat slightly if the fat starts to smoke.
7. Finish with aromatics or a splash of liquid and serve. Add garlic, ginger or herbs in the last minute so they do not burn. A splash of wine, stock or lemon juice can deglaze the pan and lift the fond into a quick sauce.

Order of operations

When sautéing a mix, add ingredients by how long they need. For a vegetable sauté: onions and carrots first (5 to 7 minutes), then peppers and zucchini (3 to 4 minutes), then greens and garlic (1 minute). For meat and vegetables, sauté the meat first, remove it, cook the vegetables, then return the meat to warm through.

Common mistakes and fixes

• Food sticks: the pan or fat was not hot enough, or you moved the food too soon. Proteins bond to metal until a browned crust forms and releases them. Wait a little longer.
• Soggy, grey food: crowded pan. Use a larger pan or cook in two batches.
• Burnt outside, raw inside: pieces are too large or heat too high. Cut smaller, or lower the heat after the initial browning.
• Burnt garlic: added too early. Add it in the last 30 to 60 seconds.
• Butter turns black: use clarified butter, mix butter with oil, or add butter at the end for flavour.
