St. Louis Ribs: 3-2-1 Vs. 2-2-1 Methods
Author
This side-by-side rib cook puts the 3-2-1 and 2-2-1 schedules on the grill at the same time. One rack gets three hours of smoke before wrapping, while the other gets two, then both follow the same wrapped and final sauced stages.

The comparison centers on tenderness, bark, moisture, smoke flavor, overall flavor, and texture. With both racks prepared the same way and cooked at 225°F, the changing smoke time is the point of the rib battle.
Why You'll Love This Recipe
This cook starts with two racks of St. Louis-style ribs trimmed to look as similar as possible. Both racks get yellow mustard and BBQ rub on each side, then rest while the grill comes up to temperature.
The two schedules are easy to follow because the first rack goes on the grill, then the second follows one hour later. From there, both racks are wrapped for the same two-hour period and finished with BBQ sauce for the same final hour.

Ingredients You'll Need
The ribs are seasoned with yellow mustard and BBQ rub, with Cowboy Crust used here. Brown sugar, BBQ sauce, and apple juice are added during the foil stage.
Use your favorite BBQ rub and BBQ sauce for both racks so the comparison stays focused on the 3-2-1 versus 2-2-1 timing. The apple juice is added in a small amount to each foil packet.
How To Make It
The Prep. Start by cleaning up both racks of St. Louis-style ribs. Trim off any excess meat, fat, or loose pieces so both racks are as similar as possible.
Remove the membrane from the back of each rack. Generously coat both sides of each rack with yellow mustard, then apply your favorite BBQ rub. I’m using Cowboy Crust. Make sure you get a nice, even coating on both sides.
Place the ribs on a cutting board and let them rest for about 20 minutes while you get the grill ready. Set Up the Grill: Fire up the Z GRILLS pellet grill and set the temperature to 225°F. Rack #1 – The 3-2-1 Rib. Place the first rack on the middle shelf and smoke it for 1 hour. After that first hour, place the second rack on the middle shelf. Now we have: 2-1 rack: 3 hours total smoke time. 2-1 rack: 2 hours total smoke time. Continue cooking until the first rack reaches three total hours and the second rack reaches two total hours. The Wrap. Remove both racks from the grill. For each rack, lay out a sheet of heavy-duty aluminum foil.
Add ribbons of yellow mustard, brown sugar, and BBQ sauce to the foil. Place each rack meat-side down into its own foil packet. Add a small amount of apple juice to each packet – just enough to provide some moisture without flooding the ribs. Wrap each rack tightly, making sure the foil packets are sealed well. Return both racks to the Z GRILLS at 225°F. Cook for 2 hours. The Finish. After two hours, carefully remove both foil packets from the grill. Be careful when opening the foil – there will be a lot of hot steam inside. Open each packet and allow the steam to escape. Flip the ribs over so the meat side is facing up. Brush both racks generously with BBQ sauce. Return both racks to the grill at 225°F for 1 final hour.
The Rib Battle: After that final hour, remove both racks from the grill. Allow them to rest on a cutting board before slicing. Now it's time to see what these two methods produced. We'll compare the 3-2-1 ribs vs. the 2-2-1 ribs based on: Tenderness. Bark. Moisture. Smoke flavor: Overall flavor. Texture. And, of course, we'll crown a winner. So… Which Method Makes Better Ribs? 2-1 or 2-2-1.
The first rack smokes for 3 hours before wrapping, while the second rack smokes for 2 hours before wrapping. Both racks are then wrapped for 2 hours and finished unwrapped for 1 hour at 225F. Set the Z GRILLS pellet grill to 225F. The ribs cook at 225F during the smoking, wrapped, and final sauced stages. Add ribbons of yellow mustard, brown sugar, and BBQ sauce to heavy-duty aluminum foil. Place each rack meat-side down in its own packet and add a small amount of apple juice for moisture. Starting the second rack after the first rack has smoked for 1 hour allows one rack to receive 3 total hours of smoke time and the other to receive 2 total hours before both racks are wrapped together. Compare the 3-2-1 and 2-2-1 ribs based on tenderness, bark, moisture, smoke flavor, overall flavor, and texture.Frequently Asked Questions
