Ribs internal temperature.
Ribs are the one cut where the thermometer does not get the final say. They usually come good somewhere around 190 to 203 F, but the reading moves a lot depending on where you put the probe. Cook them until they pass the bend test, and let the number tell you only when to start checking. USDA FSIS calls pork safe at 145 F with a rest of at least 3 minutes, and ribs clear that hours before they are tender.
145 F (62.8 C), then rest at least 3 minutes before carving or consuming
Steaks, chops and roasts (whole muscle). Food thermometer in the thickest part, away from bone, fat and gristle, read before removing from the heat source. This is a food safety floor, not a preference. Where any other number on this page is lower, this one governs.

What this covers at the counter
| Cut | Methods | Finish | Notes | Guide |
|---|---|---|---|---|
| Spareribs (full rack) | smoke | bend test, 190 to 203 F (craft) | Pork Board: 5 to 7 hours at 225 to 250 F. | Spareribs |
| St. Louis cut ribs | smoke | bend test, 190 to 203 F (craft) | Trimmed spareribs. Same time band; more even cooking. | Spareribs |
| Baby back (loin back) ribs | smoke | bend test, 190 to 203 F (craft) | Pork Board: 3 to 5 hours at 225 to 250 F. Leaner and quicker than spareribs. | Loin |
| Country-style ribs | smoke, braise | bend test, 190 to 203 F (craft) | FSIS lists them under the loin. Boneless or bone-in strips; not a rack. | Loin |
| Rib tips | smoke | bend test, 190 to 203 F (craft) | The trimmed-off sternum strip. Cartilage-rich; cook alongside. | Spareribs |
Safe comes first. Tender comes later.
190 to 203 F, bend test
Ribs are done when they pass the bend test and the meat has pulled back from the bone ends, which usually happens somewhere between 190 and 203 F. The thermometer is unreliable on ribs because the meat is thin and close to bone; FSIS and the Pork Board both say 'until fork tender'.
Bend test: Lift a rack of ribs from one end with tongs; the meat surface cracks and the rack bends near 90 degrees without breaking.
Pit 225 to 250 F. National Pork Board: loin back ribs 3 to 5 hours; St. Louis and spareribs 5 to 7 hours at 225 to 250 F; times vary with thickness. Approximate. Rest: 10 to 15 minutes.
200 to 205 F, probe tender
Chuck and short ribs follow brisket logic: pull when probe tender, commonly 200 to 205 F. The Beef Board describes chuck short ribs as tender when slow-cooked and brisket as a low-and-slow primal because it is a working muscle.
Probe tender: A thermometer probe or skewer slides into the thickest part with almost no resistance, like into soft butter.
Pit 250 to 275 F. chuck roast roughly 1.5 hours per pound; plate short ribs 6 to 8 hours at 250 to 275 F. Approximate. Rest: 30 to 60 minutes.
Where the thermometer goes
Between bones, not touching bone; a probe on ribs is a rough guide only. The meat is thin and the bones are close, so one reading can be off by a lot. Take two or three, and trust the bend test over any of them.
- Time:
- 5 to 7 hours at 225 to 250 F (Pork Board); the 3-2-1 schedule is one way to structure it, not a rule. Approximate.
- Rest:
- 10 to 15 minutes.
- Slice:
- Between the bones, meat side down so you can see them.
- The danger zone. Bacteria grow fastest between 40 F and 140 F, doubling in as little as 20 minutes. Never leave food out of refrigeration more than 2 hours, or 1 hour when the air is above 90 F. Hold hot food at or above 140 F and cold food at or below 40 F.
- Where the probe goes. Insert the thermometer into the thickest part of the food, not touching bone, fat or gristle. For thin foods insert through the side. Check large or irregular pieces in several places. For a whole bird check the innermost thigh and wing and the thickest part of the breast.
- Colour is not doneness. Appearance and colour are not reliable indicators of safety or doneness. A burger can be brown and unsafe or pink and safe. Pork at 145 F can be pink. Smoked chicken can stay pink at the bone at 165 F.
- The 3 minute rest is part of the 145 F rule. For whole-muscle beef, pork, lamb, goat and veal the safety rule is 145 F AND a rest of at least 3 minutes before carving or eating. The rest is not optional and it is not the same thing as the long barbecue rest.
- 01Following 3-2-1 by the clock on a thin rack and steaming it to mush.
- 02Saucing early and burning it (FSIS: last 15 to 30 minutes).
- 03Leaving the membrane on the bone side.
