Instant Pot St. Louis Ribs

Instant Pot St Louis Ribs. St. Louis Cut spare ribs, quick and tender from the pressure cooker.


  • 1 slab St. Louis Cut spareribs, membrane peeled off
  • 1 cup water
  • 1 tablespoon liquid smoke

Barbecue Rub (2 tablespoons of my Homemade Barbecue Rub), or use your favorite store-bought rub

  • 1½ teaspoons fine sea salt
  • ¾ tablespoon paprika
  • ¾ tablespoon brown sugar
  • ½ tablespoon chili powder
  • ½ teaspoon ground black pepper
  • ¼ teaspoon garlic powder
  • ¼ teaspoon onion powder

Barbecue sauce (1 cup of my Espresso Chipotle BBQ Sauce), or use your favorite store-bought sauce

  • ¾ cup ketchup
  • 2 tablespoons brown sugar
  • 2 tablespoons cider vinegar
  • 1 shot espresso (or 1 ounce of coffee)
  • 1 teaspoon Dijon mustard (or cheap yellow mustard)
  • ½ teaspoon soy sauce


  1. Make the rub and sauce: In a small bowl, stir the barbecue rub ingredients: salt, paprika, brown sugar, chili powder, black pepper, garlic powder, and onion powder. Break up any clumps of brown sugar with your fingers. Set aside. In a medium bowl, whisk the barbecue sauce ingredients until smooth: ketchup, brown sugar, cider vinegar, espresso, mustard, and soy sauce. Set aside for later.
  2. Remove the membrane from the ribs: On the bone side of the ribs, work a butter knife between the membrane and the bone, then grab the membrane with a paper towel and pull it away from the ribs. Pull gently but firmly; if the membrane tears while you’re pulling, work the knife under the remaining pieces and pull them off as well. Trim the flap of meat from the bone side as well - either discard it or sprinkle it with rub and add it to the pot with the ribs. (It makes a nice cook’s snack.)
  3. Season the ribs and cut the rack into 4 pieces: Sprinkle both sides of the ribs with the rub, concentrating the rub on the meaty side of the ribs. Cut the rack of ribs into 4 pieces, cutting between every 3rd bone. Pour 1 cup of water and 1 tablespoon of liquid smoke into an Instant Pot or other pressure cooker. Stack the ribs in the pot, bone side down, in a loose pile.
  4. Pressure cook the ribs for 30 minutes with a natural release: Lock the lid and pressure cook on high pressure for 30 minutes in an Instant Pot or other electric PC (use Manual, Pressure Cook, or Pressure Cook - Custom mode) or for 24 minutes in a stovetop PC. Let the pressure come down naturally, about 15 minutes. (You can quick release any remaining pressure after 15 minutes if you're in a hurry.)
  5. Sauce and broil the ribs: Put the ribs, bone side down, on a rimmed baking sheet. Brush the ribs with the barbecue sauce, then put them under a broiler set to high. Broil the ribs until the sauce is bubbling and just starting to brown, about 5 minutes. Remove the ribs from the broiler, brush with another layer of sauce, serve, and enjoy!
