How Long to Smoke Ribs
By The Recipes by Mom kitchen · Last checked October 21, 2026 · Not kitchen-tested; see how our recipes are made
Smoking pork baby back ribs at a smoker temperature of 225 to 250°F (107 to 121°C) typically takes 5 to 6 hours. Larger pork spare ribs or St. Louis cut ribs will take about 6 to 7 hours at the same temperature.
These times are general estimates. The exact duration depends on many factors, including the thickness of the ribs, the type of smoker used, and the weather. The goal for smoked ribs is cooking them until they are tender, not just for a set amount of time. A chart of typical times is a useful starting point, but always check for doneness using physical cues rather than just following the clock.
How Long to Smoke Ribs: time chart
| What | Heat | Time | Done when |
|---|---|---|---|
| Baby back ribs | 225 to 250°F smoker | 5 to 6 hours | Meat pulls back from the bones, bends easily |
| Pork spare ribs or St. Louis cut | 225 to 250°F smoker | 6 to 7 hours | Tender, bends and cracks on the surface |
| Beef back ribs | 250 to 275°F smoker | 5 to 7 hours | Probe-tender |

Good to know
- Ribs are done by tenderness, not by a single temperature
- Weather, wind and smoker type change cooking time
What changes the cooking time
The time ranges for smoking ribs are wide because several variables can affect how long they take to cook. Understanding these factors will help you manage your cooking process.
- Type and thickness of ribs: Meaty, thick ribs will take longer to cook than thinner ones. Beef back ribs have less meat than pork ribs but can still require a long cooking time to become tender.
- Smoker temperature: Maintaining a consistent smoker temperature is important. A lower temperature will cook the ribs more slowly. Dips in temperature, which can happen when you open the lid or if the fuel source wavers, will extend the cooking time.
- Type of smoker: Different smokers have different heat and smoke circulation characteristics. An offset smoker may cook differently from a pellet grill or a kamado-style cooker, which can influence the total time.
- Weather conditions: Outdoor elements like wind, cold, and humidity can affect your smoker’s ability to maintain a steady temperature. Cold and windy days often require more fuel and a longer cooking time to get the same results.
How to tell when ribs are done
Ribs are a cut of meat that becomes tender long after reaching a food-safe temperature. Pork is safe to eat at an internal temperature of 145°F (63°C). However, ribs cooked only to this point would be tough. The goal is to cook them much longer to break down connective tissues into gelatin, which makes the meat tender.
Because a final temperature is not the best indicator, look for physical signs of doneness:
- The bend test: Pick up the rack of ribs with tongs, holding it in the center. If it is done, it will bend easily and the surface of the meat will crack.
- Bone exposure: The meat will shrink and pull back from the ends of the bones as it cooks. When you see a good amount of the bone exposed, it is a sign that the ribs are getting close to done.
- Tenderness check: Use a meat probe or a toothpick to check for tenderness. It should slide into the meat between the bones with very little resistance. For beef back ribs, this probe-tender feel is the primary indicator of doneness.
Tips for better smoked ribs
A few simple practices can help you get consistent results when smoking ribs.
- Keep the smoker closed: Every time you open the smoker lid, heat and smoke escape, which can lower the temperature and prolong the cooking time. Only open it when you need to baste the ribs or check for doneness.
- Use a reliable thermometer: Use one thermometer to monitor the temperature of your smoker at the grate level and an instant-read thermometer to spot-check the temperature of the meat for safety if you are unsure.
- Allow the meat to rest: After you take the ribs off the smoker, let them rest before slicing. This allows the juices to redistribute throughout the meat, making the ribs more moist.
