Smoked Baby Back Ribs on a Pellet Grill (Better than 3-2-1)

Ask anyone what their favorite BBQ food is and most people say pork ribs (with brisket and pulled pork coming in a close second and third).

Then ask them how they like them and you can split the room. Some love their ribs dry where you get a more pure pork taste complemented by the dry rub while others like a sticky wet glaze.

Today I’ll show you how to do both styles of ribs on a pellet grill using baby back ribs. 

Smoked pork ribs

There are so many recipes and procedures out there trying to explain a simple formula on how to create the perfect rib.

The problem with attaching a timed formula to a piece of meat is that each set of ribs comes off a different animal. The quality and size can result in vastly different cooking times.

Rather than going off a timed formula like the 321 method, I suggest using your eyes and touch as a guide.

My method is just as easy as the 3-2-1 method but gives you better results.

Once you have your smoker ready and your ribs rubbed with seasoning. You will place them in your smoker. 

You need to smoke the ribs for long enough to allow the rub to set and for a rich mahogany color to develop.

You can tell the rub has set by rubbing your finger on the rub. When it doesn’t come off you can move to the next step. This usually takes around an hour and a half. 

At this point, you will wrap the ribs in foil with a mixture of sugars and butter and allow the ribs to cook until tender to the touch. When you can insert a probe without any resistance into the meat between the bones they are ready. This should roughly take a further hour. 

Once your ribs are at this stage, you can either dry them up if you like dry style ribs or you can glaze them if you like wet ribs. You do this by unwrapping the foil they lay in and putting them back in the smoker for 15 minutes, or up to an hour.

So the basic formula you want to follow is:

1. Smoke for color and until the rub doesn’t scratch off (roughly 1 and a half hours)
2. Wrap for tenderness; the meat should probe without any resistance (roughly 1 hour)
3. Glaze or dry out (15 minutes)

The key here is that you are cooking with your senses and adjusting the times. You will never have over or under cooked ribs again.

I smoked my ribs at 300°F, if you use a lower temp of 225°F, understandably, this will add more time to your cook

Ingredients for smoking Baby Back Ribs on a Pellet Grill

• Baby back ribs – Meaty, tender, and cook faster than spare ribs. Look for evenly sized racks.
• Binder – Helps rub stick. Use yellow mustard, olive oil, or hot sauce.
• Dry rub – A pork-friendly BBQ rub with sweet, salty, and spicy balance.
• Wrap ingredients – Adds moisture and flavor. Try butter, honey, brown sugar, and apple juice.
• BBQ glaze – Thick, sweet sauce for sticky ribs. Warm with honey or sugar to thicken.
• Spritz liquid – Keeps bark moist. Use apple juice, water, or a mix with vinegar or beer.

Equipment you will need

• Smoker (I used a Z Grills pellet smoker)
• Chefs knife
• Chopping board
• Saucepan pan
• Basting brush
• Instant read thermometer (I used a Thermapen ONE)

How to smoke pork ribs in a pellet smoker

1. Rib selection and trim

There are 3 main styles of ribs to choose from when cooking pork ribs. They are spare ribs, St. Louis Style ribs which are just trimmed spare ribs, and finally, baby back ribs.

I have opted for baby back ribs for this recipe, although you can use any cut of rib and they will turn out just as perfect.

Baby back ribs come from beneath the loin muscle and are connected to the backbone. They are also a lot smaller in size compared to spare ribs and St Louis Style ribs, hence the term baby. 

I like them as they are a perfect size to handle, they cook faster than spare ribs, and I just love the flavor.

To trim ribs you need to firstly remove the membrane that is attached to the bones. If left on you will get a chewy finish to your ribs and it also stops any seasoning from penetrating the bone side of the meat.

Use a butter knife to peel back the corner of the membrane, then grip with a paper towel and you should be able to pull it off in one go. 

Then it is a matter of trimming off any excess fat that may be on the ribs and also shaping them to an even thickness, so they cook evenly along the entire rack.

2. Get the smoker ready

You can make this recipe in any smoker, or even on a gas grill with the right setup. I like using a pellet grill because of the consistent temperatures and ease of operation so I can focus on perfecting the flavors. 

If you are using a pellet grill you’ll need to make sure the hopper is filled with enough wood pellets to smoke your ribs. Ribs are forgiving so you can use any smoke wood.

Set your smoker to 300°F and allow it to come up to temperature. All up it takes around 8 to 12 minutes to be ready to smoke, depending on the model of smoker you are using.

3. Smoking the baby back ribs

Once the smoker is ready at 300°F and you have your ribs rubbed with your choice of pork rub. You can place them into the pellet smoker and close the lid.

You will want to check them for color and see if there are any overly dry areas on the rub. If there are dry areas, give a quick spritz of a 50/50 mix of apple juice and apple cider vinegar. And close the lid and let the ribs smoke away for a further 30 minutes.

After an hour and a half, your ribs should have a deep mahogany color on them and if you rub a finger on the ribs, the seasoning shouldn’t come off. This means they are ready for the wrap stage.

To wrap your ribs, you will need 2 sheets of foil per rack of ribs. Due to the bones, they can be sharp and if you pierce the foil, you have a secondary layer of protection to hold in the valuable juices.

You will want to add some brown sugar, maple syrup, honey, butter and some of the spritz to the foil and lay the ribs meat side down on the wrapping ingredients.

Fold up the foil and make sure you have the ribs tightly wrapped to prevent air pockets and any chance of steaming the ribs.

These then go back into the smoker for an hour. At this time you can put all of the sauce/glaze ingredients into a heat-proof pot and stir them up and place in the smoker to thicken up and allow the sugars to dissolve.

After an hour, unwrap the ribs and stick a probe into the meat between the bones and if there is no resistance, they are ready for the next stage.

Take them out of the smoker and fold up the edges of the foil to create a boat for each rack of ribs. Flip them over showing the meat side. One rack of ribs you will glaze with the sauce we had in the smoker for the last hour and the other rack of ribs we will leave them be.

Place both racks in their foil boats back in the smoker for 15 minutes. In 15 minutes the glaze will set and the dry ribs will crust back up.

4. Serving ribs

After 15 minutes, the ribs can be sliced into individual ribs and served. 

Brushing the wet glazed ribs with a little more warmed-up glaze.

They will pair perfectly with any BBQ sides like potato salad, slaw, etc.

The hardest thing to do is decide if you prefer wet or dry-style ribs.

Whether you went with the sticky glaze or the dry rub bark, we’d love to hear how your ribs turned out. If you tried this recipe, don’t forget to leave a rating and comment below—your feedback helps us (and other BBQ lovers) keep the smoke rolling!
