To cook baby back ribs on the grill, set up indirect heat with a drip pan under the rack, cover the grill and hold it at 250°F to 300°F, and cook a 2 to 4 lb rack for 1.5 to 2 hours until it is fork tender, brushing on sauce only in the last 15 to 30 minutes. That is the Clemson Extension method for ribs on a grill, and it is the one we follow here.
Our baby back ribs half rack comes from Heritage Duroc hogs, and its product page gives an oven method at 275°F. On the grill we use the same 275°F, inside Clemson’s range, and the same doneness cue from our page: the meat pulls back from the bone ends about a quarter inch. Here is the setup for gas or charcoal, the steps, and the signs the rack is ready.
What you need for baby back ribs on the grill
- 1 half rack of baby back ribs, thawed in the fridge overnight
- 1 tablespoon olive oil
- Dry rub: 2 tablespoons brown sugar, 1 tablespoon paprika, 2 teaspoons salt, 1 teaspoon black pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder
- 1/2 cup barbecue sauce
- A grill with a lid, a disposable drip pan, tongs, and a meat thermometer
The rub is the seasoning list from our product page (olive oil, salt, pepper, paprika, garlic powder, onion powder, and a little brown sugar). Our product page does not give a serving count, so plan by appetite: a half rack is a small rack, and a hungry table may want two.
Gas or charcoal: how to set up indirect heat
Clemson’s method calls for a covered grill with a drip pan under the meat instead of direct heat. That means the fire is on one side and the ribs sit over the pan on the other, with the lid down, so the grill works like a slow oven.
| Grill | Setup | Lid temperature (Clemson: 250°F to 300°F) | Time (Clemson, 2 to 4 lb rack) |
|---|---|---|---|
| Gas | Light the burners on one side only. Set a drip pan on the unlit side and put the ribs over it. | We hold about 275°F, the temperature on our product page | 1.5 to 2 hours, sauce in the last 15 to 30 minutes |
| Charcoal | Bank the lit coals on one side. Set a drip pan of water on the other and put the ribs over it. Add coals as needed to hold the temperature. | About 275°F | 1.5 to 2 hours, sauce in the last 15 to 30 minutes |
| Either, with wood | Add a chunk of apple wood to the coals or a smoker box to the lit burner at the start | About 275°F | Same |
Use a lid thermometer or a probe clipped to the grate near the ribs. The temperature at the grate can differ from the lid reading, so check both if you can.
How to grill baby back ribs, step by step
- Pull the membrane. Flip the rack bone side up. Slide a butter knife under the thin skin at one end, grip it with a paper towel, and peel it off.
- Oil and rub. Coat the ribs in olive oil, then press the rub onto every side.
- Set up indirect heat. Fire on one side, drip pan on the other, lid closed. Bring the lid to about 275°F.
- Cook over the drip pan. Ribs bone side down, lid closed. Open the lid only to add coals or to check.
- Sauce in the last 15 to 30 minutes. Clemson says to apply sauce late so it does not burn. Brush it on and close the lid again.
- Check for tender. At 1.5 hours, test the rack. It is done when it is fork tender and the meat has pulled back from the bone ends about a quarter inch. Give it up to 2 hours.
- Rest and cut. Rest 10 minutes, as our product page says, then slice between the bones.
Do not flip the ribs. Over indirect heat the drip pan protects the meat, and every lid lift costs heat and time.
How to tell baby back ribs are done
Pork is safe to eat at 145°F with a rest, per the Clemson Extension cookout food safety fact sheet and the USDA chart it follows. Ribs are not tender at 145°F, which is why Clemson’s chart lists ribs as done when they are fork tender, not at a number.
So judge ribs by feel. Two signs together: a fork or a thermometer probe slides between the bones with no resistance, and the meat has pulled back from the bone ends about a quarter inch, the cue on our product page.
Baby backs are the leaner, shorter rack, which is why our product page lists 275°F for them and 300°F for St. Louis ribs. For more grill methods, read how to BBQ heritage breed pork, and see every cut in heritage pork fresh cuts.
Questions people ask about baby back ribs on the grill
How long does it take to grill baby back ribs?
Clemson Extension lists 1.5 to 2 hours over indirect heat for a 2 to 4 lb rack in a covered grill at 250°F to 300°F, until fork tender. Start testing at 1.5 hours.
Should ribs be wrapped in foil when grilling?
The Clemson method does not use foil on the grill; the drip pan and the closed lid keep the ribs from drying out. Our product page uses foil in the oven, so wrap only if you are cooking indoors.
What is the best way to cook ribs on a gas grill?
Light the burners on one side only, set a drip pan on the unlit side, cook the ribs over the pan with the lid closed at about 275°F, and sauce in the last 15 to 30 minutes.
How long should I grill ribs at 300 degrees?
300°F is the top of Clemson’s range, and the chart’s 1.5 to 2 hour window still applies. Test for fork tender rather than counting on a shorter time.
Should you flip ribs on a gas grill?
No. Over indirect heat with a drip pan, keep them bone side down the whole time.
A rack worth the wait. Baby back ribs on the grill are a two hour cook that the grill does for you, and Heritage Duroc ribs, raised crate free with no antibiotics ever on Iowa family farms, are the rack we would put over the coals.
