What Temperature to Sear a Steak | The Heat Range for Bistro-Quality Crust

Searing a steak at 400–450°F (204–232°C) delivers the fastest browning without burning the oil — the single range that produces a restaurant crust and a properly cooked interior.

That range is the sweet spot. Below 350°F, the steak steams instead of searing because any surface moisture can’t evaporate fast enough. Above 500°F, even high-smoke-point oils risk scorching, and the outside can blacken before the middle warms. Whether you use a cast-iron pan, a stainless skillet, or a gas grill, holding the pan or grate surface in that 400–450°F window is the move that separates a great sear from a burnt or gray one.

Why 400–450°F Matters for the Sear

The Maillard reaction — the chemical cascade that creates the brown crust and savory flavor — accelerates above 285°F. But you need higher heat to compensate for the cold steak pulling the pan temperature down the moment it hits the surface. A pan heated to at least 400°F stays hot enough to keep browning active even after the steak lands. At 450°F, you get aggressive browning in under three minutes per side without the oil reaching its smoke point if you’ve chosen the right fat.

An infrared thermometer is the reliable tool here, not guessing by the water-bead test. Point it at the empty pan after five minutes of preheat to confirm the surface is in range before adding oil.

Pan Pan vs Grill vs Cast-Iron: Temperature Differences

Pan-searing on an induction, electric, or gas cooktop targets that 400–450°F surface temp. Smart induction protocols sometimes specify searing at 425°F for two minutes per side, then dropping to 375°F to finish the interior. Grill-searing runs hotter — 450–500°F — because the grates are open and lose heat to airflow. Preheat a gas grill with all burners on high and the lid closed for 10–15 minutes; the grate surface should read around 475°F before the steak goes on.

Cast-iron or black steel pans are the material choice for searing, not nonstick. Their mass holds temperature steady when the cold steak hits, so the pan doesn’t crash below 350°F. Some dedicated cast-iron cooks preheat to 500–550°F, but that requires careful oil management and good ventilation — 400–450°F is safer and delivers a crust that is equally good.

Here is how the methods compare at a glance:

The Oil and the Internal Temp: Two Decisions That Make or Break It

Your cooking fat must handle the heat without breaking down. Avocado oil (smoke point ~520°F), grapeseed oil (~420°F), and refined high-heat coconut oil (~400°F) are all safe picks. Avoid butter during the sear — it burns below 400°F — but you can add it for basting after the crust forms and the heat drops.

Internal doneness is measured separately with a needle probe or instant-read thermometer. Medium-rare finishes at 130–135°F; medium at 135–145°F. Pull the steak from the heat when it is 5–10°F below your target — residual heat (carryover cooking) will push it the rest of the way during a five-minute rest.

A dry surface hitting a 425°F pan sears immediately.
