Ingredients

Servings:

Units:

Main

  • 1 ½ kg St Louis pork ribs, trimmed and patted dry

    One full rack or two halves, depending on crockpot size

Seasoning

  • 5 ml Kosher salt
  • 3 ml Black pepper, freshly ground
  • 5 ml Paprika(optional)
  • 3 ml Garlic powder
    (optional)

Sauce

  • 480 ml Barbecue sauce

    Add during the final 2-3 hours of cooking to prevent sauce from breaking down

    Use your favourite BBQ sauce or prepare your own

Method

  1. 1

    Remove the thin membrane from the underside of the ribs by loosening it with a knife and peeling it away. Pat the ribs dry with kitchen paper.

    ~5 mins
  2. 2

    In a small bowl, combine the salt, black pepper, paprika, and garlic powder. Rub this mixture generously all over both sides of the ribs, massaging it into the meat.

    ~5 mins

    Tip: Adjust seasonings to taste; do not skip this step as it builds flavour

  3. 3

    Optional: For enhanced flavour, quickly sear the ribs under a hot grill or in a heavy-bottomed frying pan for 2-3 minutes per side until lightly browned. This is optional but recommended.

    ~10 mins
    Optional step

    Tip: Browning adds depth to the finished dish

  4. 4

    Arrange the ribs in your crockpot, curling them if necessary to fit. If using two racks, you may need to cut them in half or stand them upright.

    ~5 mins

    Tip: Ribs do not need added liquid; they will produce their own juices

  5. 5

    Cover and cook on Low for 6 hours, or on High for 3 hours.

    ~6 hrs

    Tip: Do not lift the lid during this initial cooking phase

  6. 6

    After the initial cooking time, pour the barbecue sauce over the ribs, turning them to coat evenly.

    ~5 mins

    Tip: This timing prevents the sauce from burning or breaking down

  7. 7

    Return the crockpot to Low for a further 2 hours (or High for 1-1.5 hours), until the ribs are very tender and the meat pulls away easily from the bone.

    ~2 hrs

    Tip: Monitor in the final 30 minutes to prevent the ribs from becoming mushy

  8. 8

    Transfer the ribs to a serving platter. If desired, reduce any excess cooking liquid in the slow cooker by switching to High and simmering uncovered for 15-20 minutes, then drizzle over the ribs.

    ~10 mins
    Optional step

    Tip: This step creates a thicker sauce for serving

  9. 9

    Serve the ribs hot, with extra barbecue sauce on the side if desired.

Frequently Asked Questions

No, ribs release plenty of their own moisture as they cook slowly. Adding water will result in watery, less flavourful meat. The crockpot's sealed environment means minimal evaporation, so no additional liquid is needed for the first 6 hours of cooking
