Seasonings

  • Sweet Paprika – It adds color and flavor to these ribs.
  • Ground Black Pepper – A little bit of pepper goes quite a long way.
  • Dry Mustard – It gives these ribs that zesty flavor.
  • Garlic Powder – You can never have too much garlic. This is a must for the ribs.
  • Chili Powder – Bring color and flavor to your ribs with a bit of chili powder.
  • Cayenne Powder – Just a bit of this will add a slight kick without making the ribs too spicy.

You will also need the ingredients to prepare the homemade barbeque sauce. It’s much better than using any bottled brand you can find in the stores.

What Is the Traeger 3-2-1 Ribs Method?

The 321 method is a step-by-step process commonly used when preparing ribs in the smoker. It involves smoking the ribs for three hours on the pellet grill, two hours of wrapping them in foil on the pellet grill, and then an additional hour of cooking the ribs on the pellet grill unwrapped with a generous amount of barbeque sauce added to both sides of the meat.

It’s a surefire way to ensure you have fall-off-the-bone ribs ready to serve at the end of the night. Because this process takes time, it’s a good idea to start cooking your ribs earlier in the day.

How to Make Baby Back Ribs on Pellet Grill

Prep your ribs the night before. Use your knife to get rid of the silverskin membrane, and then apply mustard to your ribs, using it as a binder. Once you’ve applied the mustard, add your seasoning blend to every side of your ribs, place the bag of ribs in the fridge, and allow everything to marinate overnight.

The next day, set your smoker to 225°F. When it reaches the ideal temperature, put your ribs on the smoker with the meat side up, allowing them to smoke for three hours.

Remove your ribs from the smoker, place the meat side up on your foil, add your brown sugar, honey, and butter, and then seal your foil before placing the ribs back on the smoker for an additional two hours.

After two hours, open the foil, brush both sides of your ribs with the homemade BBQ sauce, and put them right back on the smoker for the last hour. Of course, you can leave them on a bit longer if you want your sauce to get nice and thick. Remove from the smoker, let sit for about 10 minutes, and then serve.

Wood Pellets – Cherry or Apple?

When it comes to these savory ribs, using apple or cherry pellets will work well. Cherry wood creates this incredible sweetness that enhances the taste of the ribs, making them both sweet and savory but not too sweet. The same thing goes for using apple pellets.

The fruit-flavored pellets add a slight touch of sweetness to anything you prepare in the smoker, meaning either option would be great when you prepare these Trager 3-2-1 Ribs.
