How To Make Instant Pot Ribs
Our easy, step-by-step guide will take the mystery out of creating this traditional barbecue rub for ribs, so that anyone from novice home cooks to seasoned pit-masters can make these tender and flavorful ribs in no time at all.
Prepare The Dry Rib Rub
- First combine all the spices into a small bowl to prepare the dry rub for the ribs.
- Coat the ribs generously and evenly with the dry rub.
Instant Pot Ribs Instructions
- Pour the water and apple cider vinegar in the Instant Pot for processing liquids. Next, place the trivet in the bottom of the Instant Pot.
- Place the pork ribs into the Instant Pot, curling them so that they wrap around the interior.
- Lock the lid on the Instant Pot, setting to 'SEAL". Hit the manual setting and set to "HI", with time set to 18 minutes.
- After the 18 minute cooking time is over, allow to Naturally Release for 10 minutes, then carefully manually release the remaining pressure and remove lid.
- OVEN BAKED INSTRUCTIONS: Place your barbecue seasoned ribs on an aluminum foil lined rimmed baking sheet. Cover the entire baking sheet and ribs with aluminum foil, sealing tightly around the edges of the baking sheet. Bake at 350 F for 3 ยฝ to 4 hours. Remove and finish with the same finishing instructions as the Instant Pot method.
Finish With Barbecue Sauce
- Turn your oven on to the 'high' broil setting and line a rimmed baking sheet with aluminum foil.
- Transfer the ribs from the Instant Pot to the aluminum lined baking sheet. Coat the ribs with the barbecue sauce.
- Place ribs under the broiler to 6 to 7 minutes, turning half way, and let the barbecue sauce on the ribs caramelize crispy on the edges.
- Remove from oven. You can add another coating of barbecue sauce if you want, and then cut into portions or serve whole on a platter. Enjoy these ribs by themselves, with fries, or with any favorite side.
Tips for Success
- Coat the raw rack of ribs generously and evenly with the dry rib rub, or other dry spice rub blend before cooking.
- Don't overcook the ribs when caramelizing the barbecue sauce finish!
Substitutions and Variations
You can use pork Baby Back ribs instead of the St. Louis ribs. Consider the spice blends below for more flavor options:

Frequently Asked Questions
St Louis ribs are flatter and straighter, whereas the baby back ribs are curved and shorter. Because they're flatter and easier to brown and get just right on the grill, they can cook more evenly, which is excellent.
From the 1930s through the 1960s, smaller meat packers in St. Louis created a new, more rectangular cut for pork spare ribs that included more meat and removed cartilage from the side of the ribs. They called them the St. Louis–style ribs cut.
