Here is a recipe for 3-Ingredient Slow Cooker Baby Back Ribs. They turn out incredibly tender, fall-off-the-bone, and require almost no effort. The three ingredients are pork ribs, a dry rub, and your favorite barbecue sauce—but if you want to count the rub as a single ingredient, this is as simple as it gets.
3-Ingredient Slow Cooker Baby Back Ribs
Prep time: 5 minutes
Cook time: 6–8 hours (low) or 3–4 hours (high)
Yield: 2–3 racks of baby back ribs (serves 4–6)
Ingredients
-
2–3 racks baby back ribs (about 4–6 lbs total)
-
¼ cup dry rub (store-bought or homemade—see below)
-
1 ½ cups your favorite barbecue sauce (plus extra for serving)
Optional (not counted in “3 ingredients” if you use store-bought rub):
-
Aluminum foil (for easy cleanup)
Instructions
1. Prep the ribs:
Remove the membrane from the bone side of each rack for more tender ribs. To do this, slide a butter knife under the thin silvery skin at one end, grab it with a paper towel, and pull it off. Rinse the ribs and pat them dry with paper towels.
2. Apply the rub:
Generously coat all sides of the ribs with the dry rub, pressing it into the meat. If time allows, wrap the ribs in plastic wrap and refrigerate for 1–8 hours (overnight is best but optional).
3. Place in slow cooker:
If your slow cooker is oval-shaped, cut each rack in half to fit. Stand the ribs upright along the sides, meat side facing the wall, or stack them with a thin layer of barbecue sauce between layers. (Stacking is fine—they’ll cook evenly.)
4. Cook:
Cover and cook on low for 6–8 hours or on high for 3–4 hours, until the meat is tender and easily pulls away from the bone.
5. Sauce and finish (optional but recommended):
Remove the ribs carefully (they will be very tender) and place them on a foil-lined baking sheet. Brush generously with barbecue sauce. For a caramelized finish, place under the broiler for 3–5 minutes until the sauce bubbles and chars slightly. Alternatively, finish on a grill over medium heat for 5–10 minutes.
6. Serve:
Slice between the bones and serve with extra barbecue sauce on the side.
Homemade Dry Rub (if you want to make your own)
Mix together:
-
2 tablespoons brown sugar
-
1 tablespoon paprika
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
1 teaspoon salt
-
½ teaspoon black pepper
-
½ teaspoon cayenne (optional, for heat)
This yields about ¼ cup—enough for 2–3 racks.
Tips & Variations
-
Low-carb/keto: Use a sugar-free dry rub and a no-sugar-added barbecue sauce.
-
Spicy: Add red pepper flakes to the rub or use a spicy barbecue sauce.
-
No broiler or grill: Serve the ribs directly from the slow cooker after saucing—they’re still delicious, just without the caramelized crust.
-
Easy cleanup: Line the bottom of the slow cooker with aluminum foil before adding the ribs for effortless cleanup.
