How to Use a Meat Thermometer | End Undercooked Meat for Good

One wrong guess with a knife slice can ruin a roast or serve undercooked chicken. A meat thermometer removes the guesswork entirely — but only if you place it right. The single most common error isn’t the tool, it’s the angle. Here’s the exact method for every cut, from a thin burger patty to a whole turkey, so dinner lands safely and on your preferred doneness every time.

Where to Insert the Probe for Every Cut

The goal is the coolest center, which is always the last part to cook. For thick roasts, steaks, chops, and whole poultry, insert the probe into the thickest section of meat, staying well clear of bone, large fat pockets, and gristle — those throw a false high reading. For thin cuts like burgers, chicken breasts, or thin steaks, insert the probe through the side, parallel to the cooking surface, so the tip reaches the middle without poking out the other side. For casseroles and egg dishes, push the probe into the center of the dish. If you’re cooking a whole bird, avoid touching the cavity or the pan; aim the probe into the thickest part of the breast or thigh instead.

The Right Way to Read the Temp

Begin checking when the meat is within about 30 minutes of being done, and keep the probe in place until the reading stops climbing. For instant-read models, some experts recommend slowly backing the probe out until the temperature dips and then rises again — the lowest point is the true center temperature. Remove the meat from heat when it reads about 5 to 10°F below your target, then let it rest. Carryover cooking will lift the internal temperature those final degrees. Common targets to remember:

Common Mistakes That Throw Off Your Reading

Touching bone, fat, or the pan is the fastest way to misread the temperature — that false high number will leave you with an undercooked center. Measuring too early also tricks you, because the outside heats faster than the middle; the center is your truth teller. Pulling the probe out before the number stabilizes is another easy miss — wait those extra five seconds. And skipping the carryover rest step means the meat will keep cooking after you pull it, taking a perfect medium-rare into medium territory.

Accuracy Checks and Probe Depth

A thermometer is only as good as its calibration. Test yours in an ice-water bath: fill a container with ice, add water, stir, and wait three minutes. Insert the probe, and within 30 seconds it should read 32°F. If it doesn’t, follow the manufacturer’s recalibration steps. Depth also matters — thermocouple sensors need only about ¼ inch, digital instant-read models want roughly ½ inch, and dial thermometers require 2 to 2½ inches to reach the sensing point. Insert the probe at least up to the notch on the metal shaft so it supports itself and stays out of the ambient heat.
