There are ribs that require hours of smoking, constant basting, and careful temperature control. And then there are these Slow Cooker Pork Spare Ribs. With just six simple ingredients and a slow cooker, you can create ribs that are impossibly tender, deeply flavorful, and glazed with a sweet, tangy, savory sauce that tastes like it came from a barbecue pit. The combination of barbecue sauce, soy sauce, apple cider vinegar, brown sugar, and garlic powder creates a complex, Asian-inspired glaze that caramelizes beautifully as the ribs cook low and slow.
Spare ribs are meatier and richer than baby back ribs, making them ideal for long, slow cooking. As they braise in the slow cooker, the meat becomes so tender it falls off the bone, while the sauce reduces into a sticky, glossy glaze that clings to every bite. Serve them with coleslaw, cornbread, or simply on their own. This is the kind of meal that will have everyone asking for seconds.

6-Ingredient Slow Cooker Pork Spare Ribs Feast
Prep Time: 10 minutes | Cook Time: 7-8 hours on LOW or 4-5 hours on HIGH | Total Time:Approximately 7-8 hours
Yield: 4 servings
Ingredients
-
3 to 3½ pounds raw pork spare ribs, cut into 3- to 4-rib sections
-
1 cup barbecue sauce (your favorite bottled, regular or smoky style)
-
¼ cup soy sauce (regular or low-sodium)
-
¼ cup apple cider vinegar
-
¼ cup packed brown sugar
-
1 teaspoon garlic powder
-
Optional: kosher salt and black pepper to taste (only if your barbecue sauce is very low in salt)
Instructions
1. Prepare the Ribs:
Place the raw pork spare ribs in the bottom of a 5- to 7-quart slow cooker, arranging them in a single layer as much as possible. It is fine if they overlap slightly or stand on edge, but aim to keep most of the meat in contact with the bottom so it braises evenly.
2. Make the Sauce:
In a medium bowl, whisk together the barbecue sauce, soy sauce, apple cider vinegar, brown sugar, and garlic powder until the sugar is mostly dissolved and the mixture is smooth. Taste the sauce; if your barbecue sauce is very mild or low in salt, add a small pinch of kosher salt and a few grinds of black pepper, keeping in mind the sauce will concentrate as it cooks.
3. Coat the Ribs:
Pour the sauce mixture evenly over the ribs in the slow cooker, lifting the rib sections slightly with tongs so the sauce can run underneath and coat the bottom pieces. The ribs do not need to be fully submerged; they will release juices as they cook, creating more braising liquid.
4. Cook:
Cover the slow cooker with its lid and cook on LOW for 7 to 8 hours, or on HIGH for 4 to 5 hours, until the meat is very tender and starting to pull away from the bones. Avoid lifting the lid during the first few hours so the slow cooker can maintain a steady temperature.
5. Transfer and Skim:
Once the ribs are tender, use tongs to carefully transfer them to a serving platter, keeping the sections intact as much as possible. Skim excess fat from the surface of the cooking liquid in the slow cooker with a spoon.
6. Thicken the Sauce (Optional):
If you like a thicker, stickier glaze, pour the cooking liquid into a small saucepan and simmer over medium heat for 5 to 10 minutes, stirring occasionally, until slightly reduced and glossy. Alternatively, leave it as is for a looser, more spoonable sauce.
7. Serve:
Spoon the sauce generously over the ribs on the platter, or serve it on the side for dipping. Serve hot, with plenty of napkins.
Recipe Notes & Pro Tips
Spare Ribs vs. Baby Back Ribs: Spare ribs come from the belly side of the rib cage. They are meatier, have more fat and connective tissue, and are larger than baby back ribs. They are ideal for slow cooking because the long, gentle heat breaks down the fat and collagen, resulting in incredibly tender, flavorful meat. Baby back ribs can also be used; reduce the cooking time by about 1 hour.
Cut the Ribs into Sections: Cutting the rack into 3- to 4-rib sections makes them easier to fit into the slow cooker, ensures even cooking, and makes serving simpler. Use a sharp chef’s knife or cleaver to cut between the bones.
Do Not Add Extra Liquid: The ribs release their own juices as they cook, which combine with the sauce to create plenty of braising liquid. Adding extra water or broth will dilute the flavor.
Thicker Glaze: The sauce in the slow cooker will be thin because the ribs release juices as they cook. Reducing the sauce on the stovetop concentrates the flavors and creates a sticky, glaze-like consistency. This step is optional but highly recommended for that classic barbecue rib experience.
Broiler Finish (Optional): For a caramelized, sticky exterior, transfer the cooked ribs to a foil-lined baking sheet, brush with the reduced sauce, and broil for 3-5 minutes, watching closely, until the edges bubble and char slightly.
Add Heat: For spicy ribs, add 1 teaspoon of red pepper flakes, 1 tablespoon of sriracha, or 2 chopped chipotle peppers in adobo sauce to the sauce mixture.
Variations
Honey Soy Spare Ribs: Substitute the brown sugar with ¼ cup of honey and use an additional ¼ cup of soy sauce. The honey adds a floral sweetness and helps create a sticky glaze.
Dr Pepper Spare Ribs: Substitute the apple cider vinegar with ¼ cup of Dr Pepper or root beer. The soda adds a deeper, more complex sweetness.
Garlic Ginger Spare Ribs: Add 1 tablespoon of fresh grated ginger and an extra 2 cloves of minced garlic to the sauce mixture. The ginger adds warmth and brightness.
Spicy Korean-Style Ribs: Add 2 tablespoons of gochujang (Korean chili paste), 1 tablespoon of sesame oil, and 1 teaspoon of grated ginger to the sauce mixture. Garnish with sesame seeds and sliced green onions.
Smoky Ribs: Use a smoky barbecue sauce and add 1 teaspoon of liquid smoke and 1 teaspoon of smoked paprika to the sauce mixture. This mimics the flavor of hours on a smoker.
Pineapple Spare Ribs: Add 1 cup of drained crushed pineapple to the slow cooker along with the sauce. The pineapple adds sweetness and helps tenderize the meat.
Serving Suggestions
These ribs are a complete meal on their own, but they pair beautifully with classic barbecue sides:
-
Coleslaw (for crunch and acidity)
-
Cornbread or dinner rolls
-
Baked beans
-
Potato salad or macaroni salad
-
Roasted corn on the cob
-
Collard greens or green beans
For a low-carb meal, serve with cauliflower mash or a crisp green salad.
Storage & Reheating
Store leftover ribs in an airtight container in the refrigerator for up to 4 days. Separate the ribs from the sauce to prevent them from becoming too soft.
To reheat, place the ribs on a foil-lined baking sheet, brush with extra sauce, and warm in a 300°F oven for 10-15 minutes. You can also reheat in a covered skillet over medium-low heat with a splash of water or extra sauce.
These ribs freeze well for up to 3 months. Cool completely, then wrap tightly in plastic wrap and foil. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
The slow cooker is ideal for spare ribs because it provides gentle, consistent heat over many hours. This low-and-slow environment breaks down the collagen and connective tissue in the pork, transforming tough, chewy ribs into meat that literally falls off the bone.
The combination of barbecue sauce, soy sauce, apple cider vinegar, brown sugar, and garlic powder creates a sauce that is sweet, tangy, savory, and complex. The barbecue sauce provides smoky, tomato-based flavor. The soy sauce adds umami and saltiness. The apple cider vinegar adds brightness and helps tenderize the meat. The brown sugar provides deep, molasses-like sweetness. The garlic powder adds savory depth.
Reducing the sauce after cooking concentrates these flavors, transforming the thin cooking liquid into a thick, sticky glaze that clings to every rib. The optional broiler finish adds a caramelized, slightly charred exterior that mimics the texture of grilled or smoked ribs.
This recipe is proof that you do not need a backyard, a smoker, or any special equipment to make ribs worth writing home about. With six simple ingredients and a slow cooker, you can create spare ribs that are sweet, sticky, tender, and absolutely delicious. Perfect for game day, summer cookouts, or any time you crave barbecue.
