What are baby back ribs

Baby back ribs are pork ribs that are near the back or loin area of a pig. The bones are arched and are smaller than St. Louis style ribs, which are cut from near the belly of the pig.

  • Baby Back Ribs: Baby back ribs are smaller pork ribs with arched bones.
  • Yellow Mustard: This acts as a binder to help the rub stick.
  • Barbecue Rub: Use your favorite barbecue rub. I recommend trying my award-winning Pork Rub or try my recipe for All-Purpose BBQ Rub.
  • Barbecue Sauce: You can serve your ribs dry or wet. If you like them wet, add your favorite barbecue sauce toward the end.
Substitutions: If you don't like mustard, you can use vegetable oil or hot sauce for the binder.

How to Grill Baby Back Ribs on the Woodfire Grill

  1. STEP ONE: Start by removing the ribs from the package. Pat them dry with a paper towel. If the ribs have a membrane layer on top of the bones, pull that off.
  1. STEP TWO: Apply yellow mustard to both sides of the ribs and sprinkle liberally with your favorite barbecue rub.

The full rack of ribs will be too large for the Ninja Woodfire Grill, so cut it in half.

Let the ribs rest while you setup the grill. For added flavor, you can even do this step the night before and allow the rub to really penetrate the meat.

  1. STEP THREE: Add a cup of wood pellets to the smoke box of the Ninja Woodfire Grill. Set the grill to smoke. Then, set the temperature to 300F degrees and the time to 2 hours.
  1. STEP FOUR: Add the ribs to the grill, placing them side by side and close the lid. Smoke for 90 minutes.

  1. STEP FIVE: After 90 minutes, brush the ribs with sauce and smoke for 15 more minutes. The internal temperature of the ribs should reach about 205F degrees.

NINJA PRO TIP: You can customize your half rack of ribs by using different sauces on each half, or leave one half dry and only applying sauce to the other half.

  1. STEP SIX: Remove the ribs from the grill. Place them on a cutting board with the bones facing up. Slice the ribs between the bones. Add more sauce to the bottoms and sides and sprinkle with a little more rub.

How to serve baby back ribs

Wait to slice your ribs until just before you serve them. That will keep them from drying out.

  1. Super good! Seriously impressive smoky flavor. Way better than any I’ve made on a gas grill. Mine came out a bit darker but I also realized I had the heat up a little. Tasted delicious anyway and will definitely be making again. Thank you!

    1. Hi Roy, I’m sorry you didn’t like this recipe. I like cooking my ribs hot and fast. I’ve followed this recipe several times with no problem. What issues did you have?

    1. It depends on how smoky you like them. For mild smoke, just add one scoop. For more smoke, add another scoop after about 1 hour.

  2. Thanks for the recipe! In the instructions you mention to let the ribs rest while you heat the grill and then add them once it is ready. Even though the smoker function doesn’t have a built in preheat stage, do you let it heat up before adding the ribs?
