Ingredients
For the Ribs
-
2 racks baby back ribs (about 4–5 lbs total)
-
1 tbsp yellow mustard (to coat ribs before seasoning)
Dry Rub
-
2 tbsp brown sugar
-
1 tbsp smoked paprika
-
1 tbsp garlic powder
-
1 tbsp onion powder
-
1 tsp black pepper
-
1 tsp salt
-
½ tsp cayenne (optional, for heat)
Carolina Mustard Sauce
-
1 cup yellow mustard
-
½ cup apple cider vinegar
-
¼ cup honey (or brown sugar)
-
2 tbsp ketchup
-
1 tbsp Worcestershire sauce
-
1 tsp red pepper flakes
-
½ tsp black pepper
-
½ tsp salt
Instructions
1. Prep the ribs
-
Remove membrane from the back of each rack (grip with a paper towel and pull).
-
Pat ribs completely dry.
-
Brush a thin layer of yellow mustard over both sides – this helps the rub stick and adds tang.
2. Apply dry rub
-
Mix all dry rub ingredients in a small bowl.
-
Generously coat all sides of the ribs.
-
Optional but recommended: Let seasoned ribs sit in the fridge for 1–2 hours (or overnight) for deeper flavor.
3. Make the sauce
-
Whisk together all sauce ingredients in a bowl or jar.
-
Set aside ½ cup for later (to serve with finished ribs).
4. Slow cook
-
Cut each rib rack into 3–4 rib portions so they fit easily in the slow cooker.
-
Place rib pieces in the slow cooker, stacking them if needed.
-
Pour half of the remaining sauce over the ribs (about ¾ cup).
-
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours until meat is very tender but not totally falling apart.
5. Thicken sauce (optional but recommended)
-
Carefully remove ribs to a foil‑lined baking sheet.
-
Pour slow cooker juices into a small saucepan.
-
Simmer over medium heat for 5–10 minutes until reduced and slightly thickened.
-
(Or whisk in a cornstarch slurry: 1 tsp cornstarch + 1 tbsp water.)
6. Glaze & finish
-
Brush ribs generously with the reduced sauce (or fresh reserved sauce).
-
For caramelized edges: place ribs under the broiler for 2–4 minutes (watch closely!).
-
Or serve as is for the ultimate tender, no‑fuss version.
7. Serve
-
Pour remaining reserved sauce on the side for dipping.
-
Classic sides: coleslaw, baked beans, pickles, cornbread.
Pro Tips
-
Don’t drown the ribs in sauce during cooking – too much liquid can make them mushy. Half the sauce is plenty.
-
Baby backs vs. spareribs: Baby backs cook faster and fit better. For spareribs, add 1–2 hours on LOW.
-
No broiler? No problem – these are amazing straight from the slow cooker.
-
Make ahead: Cook, cool, and refrigerate in the sauce. Reheat gently on the stovetop or in a low oven.
