How long does it take to smoke ribs on a Weber kettle?

Smoking ribs on a Weber kettle grill is a popular way to infuse tender, fall-off-the-bone rib meat with delicious smoky barbecue flavor. The exact amount of time needed to smoke ribs on a Weber kettle depends on a variety of factors, including the size and type of ribs being cooked, the cooking temperature, and the desired degree of doneness.

Quick Overview

On average, smoking ribs on a Weber kettle grill takes between 4-6 hours depending on the size of the ribs and desired tenderness. Baby back ribs take 4-5 hours while spareribs can take up to 6 hours due to their larger size. The ribs are done when the meat has pulled back from the bones by at least 1⁄4 inch and the meat probes tender when poked with a fork or toothpick.

Detailed Cooking Times

Here is a more detailed look at approximate smoking times for ribs on a Weber kettle:

Baby Back Ribs

  • 2 racks of baby back ribs (4-5 lbs total): 4-5 hours
  • 3 racks of baby back ribs (6-7 lbs total): 5-6 hours

Spareribs

  • 2 racks of spareribs (6-7 lbs total): 5-6 hours
  • 3 racks of spareribs (9-10 lbs total): 6-7 hours

St. Louis Style Ribs

  • 2 racks (5-6 lbs total): 5-6 hours
  • 3 racks (7-9 lbs total): 6-7 hours

The ribs are done when you can twist a bone and it rotates easily. The meat should have shrunk back from the ends of the bones by at least 1⁄4 inch. Use a fork or toothpick to test tenderness – it should slide in and out of the meat easily when they are fully cooked.

Factors That Affect Cooking Time

There are several factors that can affect the amount of time it takes to smoke ribs on a Weber kettle grill:

Type and Size of Ribs

The type of ribs will impact cooking time. Meatier spareribs take longer to smoke than smaller baby back ribs. Larger ribs also require more time than smaller slabs.

Number of Racks

The more racks of ribs you smoke, the longer the overall cooking time. Each additional rack adds roughly 1 hour to the total time.

Cooking Temperature

If smoking at a higher temperature (275-300°F), ribs will cook faster than smoking low and slow (225-250°F). Lower, slower smoking gives the most tender results.

Wood Chips vs. Chunks

Wood chips create smoke faster but burn off quickly. Chunks provide smoke over a longer period. Using only chips may require replenishing more often during the smoke.

Meat Temperature

Pulling the ribs off the grill once they reach an internal temperature of 195-205°F will result in more tender meat than pulling them off based on time alone.

Desired Tenderness

The longer you smoke the ribs, the more tender the meat will become. If you prefer fall-off-the-bone ribs, smoke them for a longer amount of time.

Tips for Smoking Ribs on a Weber Kettle

Follow these tips for smoking delicious, tender ribs on your Weber kettle grill:

  • Trim off any excess fat or membrane for more even cooking.
  • Rub the ribs all over with a dry rub or spice mix for flavor.
  • Use indirect heat by pushing the coals to one side and placing the ribs on the other.
  • Add wood chips or chunks to generate smoke – use apple, cherry, hickory, etc.
  • Maintain a temperature between 225-275°F by adjusting the vents.
  • Flip and rotate the ribs every 1-2 hours for even cooking.
  • Wrap ribs in foil at the midway point to power through any stall.
  • Brush with barbecue sauce during last 30-60 minutes once bark has formed.
  • Let ribs rest for 10-15 minutes before cutting and serving.

Step-By-Step Guide

Follow this simple step-by-step guide for smoking ribs on a Weber kettle grill:

1. Prepare the Ribs

Start by trimming any excess fat or membrane from the backside of the ribs for better absorption of smoke and seasoning. Peel off the membrane then rub the racks all over with a dry spice rub. Let them sit while you prep the grill.

2. Set Up the Grill for Indirect Heat

Pile charcoal on one side of the grill and light it. Replace the cooking grate once the coals are hot. Add soaked wood chunks or chips onto the hot coals for smoke. The ribs will cook over indirect heat on the empty side.

3. Place the Ribs on the Grill

Lay the rib racks meat side up on the empty side of the grill away from the coals. Try to maintain a temperature of 225-275°F by adjusting the vents. Close the lid.

4. Maintain the Temperature

Monitor the temperature and adjust the vents as needed to maintain 225-275°F. Add more hot coals or wood chunks if needed to replace what has burned through. Keep the lid closed as much as possible.

5. Flip and Rotate

Flip and rotate the ribs every 1-2 hours for even cooking. This helps prevent hot spots. If any areas are cooking faster, rotate that section away from the heat or shield it with foil.

6. Wrap in Foil

Once the ribs have smoked for a couple of hours, wrap them tightly in foil. This steams the meat to get through any stall. Return to the grill to finish cooking.

7. Glaze and Crisp

Unwrap the ribs during the last 30-60 minutes. Brush with barbecue sauce to glaze and increase caramelization. Keep the lid off during this time to crisp them back up.

8. Rest and Serve

When the ribs are fully cooked, remove from heat and let rest for 10-15 minutes before cutting. This allows the juices to redistribute. Slice between the bones and serve!

How to Tell When Ribs Are Done

Determining doneness for ribs can be tricky. Here are some ways to test when they are ready to come off the grill:

  • The meat has shrunk back from the ends of the bones by at least 1⁄4 inch.
  • A fork or toothpick slides in and out of the meat easily.
  • The meat between the bones cracks and begins to split when bent.
  • The internal temperature taken in the thickest part of the meat reaches 195-205°F.
  • The ribs pass the bend test – pick up the slab from one end and if it starts to break they are likely done.

The most reliable way is to use a meat thermometer to check the internal temperature. Look for 195-205°F in the thickest section once the ribs have smoked for the estimated time based on their size.

Troubleshooting

Having trouble getting perfect smoked ribs off your Weber? Use this troubleshooting guide:

Issue Cause Solution
Ribs taking too long Cooking temp too low Increase air flow to raise temp
Thick membrane on ribs Trim membrane for faster cooking
Ribs burning or bitter taste Cooking temp too high Close vents to lower temp
Too much smoke Use fewer wood chips, space out additions
Ribs not getting smoke flavor Not enough smoke Add more wood chips or chunks
Smoking too hot and fast Lower temp to 225-250°F
Tough, chewy ribs Undercooked Cook longer until tender
Cooked unevenly Rotate ribs and distribute heat evenly
Dry ribs Overcooked Spritz with juice/cider, don’t oversmoke
Not enough moisture Wrap earlier, add liquid when foiling

Conclusion

Smoking ribs on a Weber kettle grill delivers finger-licking, barbecue-flavored results. For baby back ribs, plan on 4-5 hours of smoking time, while meatier spareribs can take up to 6-7 hours to fully cook low and slow. Maintaining an even temperature between 225-275°F and using an instant-read thermometer are keys to perfectly smoked ribs. With a little practice using the vents to control heat and generating the right amount of smoke, your Weber kettle can produce competition-worthy ribs.
