Food Thermometer Placement by Meat Type: A Stage-by-Stage Guide

Start with the Right Tool and a Clean Probe

Before you take any reading, confirm your thermometer is designed for the job. An instant-read digital thermometer works for most cuts, but a leave-in probe thermometer is better for large roasts that spend over an hour in the oven. Both types measure internal temperature, not surface heat, which is what determines doneness.

Calibrate the thermometer if it allows adjustment. Fill a glass with ice and water, stir for 30 seconds, and the probe should read 32°F (0°C). Boiling water should read 212°F (100°C) at sea level. If it is off by more than 2 degrees, adjust it or replace the unit.

Wash the probe with hot soapy water before and after each use, especially when moving between raw meats. Inserting a dirty probe can push surface bacteria into the interior of the food, which defeats the purpose of checking temperature in the first place.

• Instant-read: good for steaks, chops, fish fillets, and burgers
• Leave-in probe: good for roasts, whole poultry, and brisket
• Infrared: not for internal temperature; avoid for doneness checks

Beef: Insert into the Thickest Part, Away from Bone

For steaks and roasts, the probe should enter the side of the meat, not the top. Push it into the thickest portion, which is usually the center of the cut. Avoid touching bone, because bone conducts heat differently and will give a falsely high reading. Fat also reads differently, so aim for lean muscle.

For a steak that is 1 inch thick, insert the probe horizontally from the side until the tip reaches the middle. For a roast like a ribeye or sirloin, insert from the top down into the center, again avoiding bone. If the cut is uneven, take two readings at different spots and trust the lower one.

Doneness for beef is a personal choice, but the USDA recommends cooking whole cuts to at least 145°F (63°C) followed by a three-minute rest. If you prefer medium-rare, pull the meat at 130°F (54°C) to 135°F (57°C), because carryover cooking will raise it about 5 degrees while it rests.

Poultry: Check the Thigh, Not Just the Breast

Poultry is the one meat where you cannot rely on a single reading. The breast and thigh cook at different rates, and the thigh is the last part to reach a safe temperature. Insert the thermometer into the inner thigh, close to the body cavity but not touching bone. The tip should be in the thickest part of the thigh muscle.

For a whole chicken or turkey, take a second reading in the breast, inserting from the side toward the center. The breast should read at least 165°F (74°C), and the thigh should also reach 165°F (74°C). If the breast is done but the thigh is not, return the bird to the oven and check again in 10 minutes.

For bone-in chicken pieces like thighs or drumsticks, insert the probe into the thickest part, parallel to the bone, and make sure the tip is not resting against it. Boneless breasts should be probed from the side at the thickest point. Ground poultry, like turkey burgers, should be checked in the center of the patty, which is the last area to cook.

Pork: Aim for the Center of the Loin or Chop

Pork has changed its recommended cooking temperature. The USDA now says whole cuts of pork are safe at 145°F (63°C) with a three-minute rest, which leaves the meat slightly pink in the center. This is a change from the older 160°F (71°C) guideline that produced dry, overcooked pork.

For a pork chop or tenderloin, insert the probe into the side of the thickest part, avoiding the bone and any pockets of fat. A pork loin roast should be probed from the top down into the center, and you may need to check two spots because a roast can cook unevenly from end to end.

Ground pork, like sausage patties or meatballs, must reach 160°F (71°C). Insert the probe into the side of the patty or the center of the meatball. Because ground meat is mixed, bacteria can be distributed throughout, so there is no room for a lower target temperature.

Fish: Probe the Thickest Fillet or Steak at an Angle

Fish is thinner than most meats, so placement matters more. For a fillet, insert the probe from the side into the thickest part, angling it so the tip sits in the center of the flesh without poking through to the pan. For a thick steak like salmon or halibut, insert from the side toward the center.

The FDA recommends cooking fish to 145°F (63°C), but many cooks prefer to pull it at 135°F to 140°F (57°C to 60°C) and let carryover heat finish it. The flesh should flake easily with a fork and be opaque throughout. If the fish is very thin, less than half an inch, a thermometer may not give an accurate reading; rely on visual cues instead.

For shellfish like shrimp or scallops, a thermometer is impractical because the pieces are too small. Cook them until the flesh is opaque and firm. If you are cooking a large fish roast or a whole fish, insert the probe into the thickest part near the head, and check both sides if the fish is thicker than 2 inches.

Resting: The Final Stage That Changes Your Reading

Resting is not optional. When you remove meat from heat, the internal temperature continues to rise for several minutes because heat from the outer layers moves inward. This carryover cooking can add 5 to 10 degrees for large roasts, and less for thin cuts like steaks or chops.

The probe should be removed before resting, because the hole it leaves can let juices escape. Let the meat rest on a cutting board or a warm plate, loosely tented with foil. The rest time varies by size: a steak needs 5 minutes, a pork loin 10 minutes, and a whole turkey 20 to 30 minutes.

After resting, the final temperature is what determines safety and doneness. If you pull beef at 130°F (54°C) for medium-rare, it will climb to about 135°F (57°C) during the rest. Poultry should be pulled at 160°F (71°C) because it will reach 165°F (74°C) while resting. Check the final temperature with a clean probe if you want confirmation, but insert it into a fresh spot, not the original hole.

Troubleshooting Uneven Results and Thick Cuts

If your meat reads done on the outside but raw in the center, the problem is usually cooking temperature too high or the meat was too cold when it went in. Let large cuts sit at room temperature for 30 to 60 minutes before cooking, and use a lower oven temperature for thick roasts to allow even heat penetration.

For roasts with a bone, like a standing rib roast or a leg of lamb, the meat near the bone cooks slower than the outer muscle. Take readings in at least two locations and trust the reading from the deepest point. If you are using a leave-in probe, place it in the thickest muscle and set the alarm for your target pull temperature.

When cooking multiple pieces of meat, like a tray of chicken breasts or pork chops, check each piece individually. They will not cook at the same rate, even if they look identical. The safe approach is to test the thinnest piece first; if it is done, the thicker ones likely need more time, so verify them separately.
