Description

Tender and flavorful slow cooker pork ribs seasoned with a smoky spice rub and coated generously with your favorite BBQ sauce. These ribs are slow-cooked to perfection, resulting in fall-off-the-bone texture with minimal effort, and can be finished under the broiler for a caramelized finish.


Ingredients

Units Scale

Meat

  • 1 rack pork baby back ribs (~3 lbs)

Spice Rub

  • 1/4 cup light brown sugar
  • 1/2 tsp cayenne pepper
  • 1/2 tsp smoked paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • Salt and pepper, be generous

BBQ Sauce

  • 1 1/2 - 2 cups BBQ sauce, use your favorite

Instructions

  1. Remove the membrane: Use a knife to lift one corner of the membrane on the ribs. Grip it with a paper towel and pull it straight up and away to remove and discard.
  2. Pat dry and slice: Thoroughly pat the ribs dry with paper towels and slice the rack in half with a sharp knife.
  3. Prepare dry rub: Mix light brown sugar, cayenne, smoked paprika, garlic powder, onion powder, salt, and pepper in a small dish until well combined.
  4. Season ribs: Generously season all sides of the ribs with the dry rub mixture.
  5. Layer ribs with BBQ sauce: Place half a rack of ribs in a 6-7 quart slow cooker, meat side up. Brush or pour BBQ sauce over the ribs to coat thoroughly. Add the other half of the ribs and repeat coating with BBQ sauce.
  6. Slow cook: Cook on low for 6-7 hours or on high for 3-5 hours. For slightly chewy but tender ribs, cook high for about 3 ½ hours. For fall-off-the-bone tenderness, cook low for 6-7 hours.
  7. Optional broiling: Transfer ribs to a foil-lined baking sheet. Brush with additional BBQ sauce and broil for 3-5 minutes until sauce bubbles and thickens for caramelized ribs.
  8. Serve: Slice ribs and serve warm with your favorite sides. Store leftovers in the fridge for up to 3-4 days.

Notes

  • Choose a BBQ sauce with bold flavor since slow cooking doesn’t impart smoky BBQ flavors.
  • Baby Back or St. Louis style ribs both work well; adjust cooking time based on rib thickness and tenderness preferences.
  • If possible, ask your butcher to remove the membrane to save prep time.
  • Monitoring slow cooker time is key; under- or over-cooking affects tenderness and chewiness.
  • Broiling at the end gives ribs a delicious caramelized finish but is optional.
