Slow Cooker Baby Back Ribs Recipe

These flavorful Slow Cooker Ribs turn out perfectly every time! The secret is coating them in a homemade dry rub, slathering them in sticky-sweet barbecue sauce, and slowly cooking them until they are so tender that the meat falls off the bone.

Ingredients

  • 1 (3-5 pound) rack baby back ribs OR, 2 (1½-2½ pound) racks
  • 3 tablespoon light or dark brown sugar packed
  • 2 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • ½-1 teaspoon black pepper
  • 2 tablespoon Dijon mustard
  • cups BBQ Sauce homemade or store-bought, plus more for serving

Instructions

  • Remove the membrane. Place the ribs so the bone side faces up. Use a butter knife (or your fingers) to lift a corner of the membrane from one end of the rack. Grab the loosened end with a paper towel and pull it off in one slow, steady motion.

  • Cut the rack and pat them dry. If your rack is too large to fit in your slow cooker, cut it into 2-3 sections to fit. Pat both sides dry with paper towels.

  • Mix the dry rub. In a small bowl, combine the brown sugar, smoked paprika, garlic powder, onion powder, salt, and black pepper.

  • Coat with Dijon mustard. Use a pastry brush to rub the Dijon mustard over both sides of the ribs (the mustard helps the seasoning stick).

  • Apply the rub. Generously season both sides of the ribs with the seasoning mix.

  • Arrange in the slow cooker. Spread ¼ cup of barbecue sauce in a 6-quart (or larger) slow cooker and arrange the ribs to fit. Top with the remaining BBQ sauce.
    The other half of the seasoned baby back pork ribs covered in BBQ sauce are placed in a slow cooker with the other half a rack of seasoned baby back pork ribs covered in BBQ sauce underneath.
  • Cook on low or high. For fall-off-the-bone ribs, cook on LOW for 6-8 hours or HIGH for 4-5 hours (still tender but slightly firm). If possible, baste the ribs with the BBQ sauce every 2-3 hours.

  • Broil (Optional): Carefully remove the ribs from the slow cooker and place them on a foil-lined baking sheet. Brush with additional BBQ sauce and broil on high for 3 minutes, until caramelized and slightly charred.
  • Rest and Serve. Let the ribs rest for 5 minutes, then slice between the bones. Serve with extra BBQ sauce if desired.

Notes

The Nutritional Information is based on a recipe using 4 pounds of baby back pork ribs. The calculation is for six servings, but this will vary depending on how hungry people are.
  • For the most tender ribs, cook on LOW for 6–8 hours. If you're short on time, HIGH for 4–5 hours will work, but low heat is best.
  • Ribs: I prefer this recipe with baby back ribs, but pork spare ribs will also work.
  • Two racks of ribs, approximately 5 pounds total, will fit in a 6-quart slow cooker. However, it's best not to overcrowd the slow cooker.
  • Make-Ahead: The ribs can be prepped, coated in the spice rub, and refrigerated for up to 24 hours before cooking.
  • Storage: Cool to room temperature, then place them in an airtight container or wrap them tightly in foil. Refrigerate for up to 4 days. 
  • Freezing: Wrap them tightly in foil, then place them in a freezer-safe bag or container. Store for up to 3 months. Thaw in the refrigerator before reheating.
  • Reheating: Reheat leftovers in a 350°F (175°C) oven for about 15 minutes, brushing with extra BBQ sauce if needed. You can also microwave them in 30-second intervals, though this may dry them out.
