How Long to Cook Ribs in the Oven

I love ribs. Not smoked ribs, so please do not come for me, but a good slow-baked rack of ribs with seasoning and sauce is absolutely my thing.

If smoked ribs are your favorite, that is fine. I am not pretending to be a barbecue purist here. I am talking about oven ribs, and more specifically, how long they actually need to cook if you want them tender.

The short answer is that it depends on the size of the rack, the type of ribs, and your oven, but these are good general oven times:

• 250 degrees F: about 3 1/2 to 4 hours
• 275 degrees F: about 2 1/2 to 3 1/2 hours
• 300 degrees F: about 2 to 3 hours

Anything much hotter than 300 degrees F starts working against you. Ribs are a tougher cut, and they need time more than aggressive heat. If you rush them, they are more likely to dry out before they get properly tender.

For me, low and slow is the only way to go.

Prepping Your Ribs

The first thing I recommend is removing the membrane from the back of the ribs. You can get it started with a sharp knife, then grab it with your hands or a paper towel and pull it off.

Can you leave it on? Sure, if you absolutely want to. But the texture is better if you remove it, so I think it is worth the extra minute.

Once that is done, season the ribs on both sides. You can use a store-bought pork rub, a homemade spice blend, or just keep it simple. If you are new to making ribs at home, salt, pepper, and garlic are a great place to start.

After seasoning, wrap each rack tightly in foil. I like to spray the inside of the foil lightly with cooking spray or use parchment under the foil, so the ribs do not stick.

The important part is wrapping them well and keeping each rack in its own packet. Put them on a sheet pan in a single layer. Do not stack them.

Baking

Once the ribs are prepped, place them in a preheated oven.

My preferred temperature range is 250 to 275 degrees F. Depending on the size of the rack and your oven, they will usually need somewhere between 2 1/2 and 4 hours.

That is really the whole method. Let the oven do the work.

If you are baking more than one tray at a time, rotating the pans halfway through is not a bad idea. Otherwise, leave them alone and let them cook slowly.

How to Tell When Ribs Are Done

Texture matters more than the temperature or the clock.

Once the ribs are getting close to the expected cook time, check for tenderness. The meat should pull away from the bones fairly easily, and the rack should bend without feeling tough.

If you want to use a thermometer, ribs are often in a good place somewhere around 195 to 200 degrees F, but I would still pay more attention to texture than the exact number.

Ribs are done when they are tender, not just technically cooked.

Resting

Once the ribs are done, let them rest before unwrapping them.

I usually let them rest for about 10 to 20 minutes. That gives the juices time to settle a bit and helps the temperature even out.

After that, you can unwrap them and eat them as-is, but I usually like to finish them one more time.

Second Bake

If you want saucy ribs, this is the point where I would brush them with barbecue sauce and return them to the oven.

Put the unwrapped ribs back on a baking sheet, brush them with sauce, and bake them at 350 degrees F for about 10 to 15 minutes, just until the sauce starts to caramelize.

You can also use the broiler for a few minutes if you want a little more color and stickiness. Just keep a close eye on them so the sauce does not burn.

Storage

If you are not eating the ribs right away, let them cool and store them in the refrigerator.

Cooked ribs are best used within 3 to 4 days in the fridge.

They also freeze well. Wrap them tightly and freeze them for longer storage. When you are ready to use them, thaw them in the fridge and then reheat.

Alternatives to Baking

I am not trying to write a barbecue manual here, so I am sticking mostly to the oven, but there are a couple of other ways to get tender ribs at home.

Crock Pot

You can cook ribs in a slow cooker if you want very tender results.

To do that, remove the membrane, season the ribs, and either lay them down or curl them to fit the pot. You may need to cut the rack in half. Add enough water to come about halfway up the ribs. You do not want them fully submerged, but you also do not want the liquid to cook off completely. I usually add onion and barbecue sauce to the liquid for more flavor.

Cook on low for about 8 hours or on high for about 3 to 4 hours.

This method gives you very soft ribs, though the texture is obviously different from baked ribs.

Braising

Braising is another good option if you want very tender ribs, and it is actually the method I use most often in my restaurant. It works especially well when you are cooking a larger amount of ribs.

Use a deep pan or Dutch oven, season the ribs, and stand them on their side if possible. Add enough water to cover about one-half to three-quarters of the meat. I also add onion and barbecue sauce to the liquid for more flavor. Cover the pan tightly with foil and cook at 325 to 350 degrees F for 3 to 4 hours, checking for tenderness as they cook.

Once the ribs are tender, finish them with sauce or spice rub and return them to the oven or put them under the broiler.
