Slow Cooker Baby Back Ribs

These slow cooker baby back ribs are fall-off-the-bone tender, packed with flavor, and so easy to make. Just season them, set the slow cooker, and let it do all the work.

I love making ribs this way because you don’t need a smoker or a grill. Everything happens right in your kitchen, and the result is just as delicious.

The ribs get coated in a simple homemade spice rub that gives them a smoky, slightly sweet flavor. Then they cook low and slow until the meat is super tender.

At the end, you brush them with BBQ sauce and broil for a few minutes. That step gives them those sticky, caramelized edges that make ribs so good.

If you’ve never made ribs at home before, this is the perfect place to start. It’s a straightforward recipe that delivers amazing results every time.

What Makes This Recipe So Good

Truly Hands-Off Cooking – You spend about 10 minutes on prep and the slow cooker does all the heavy lifting for hours, which means you get fall-off-the-bone tender ribs without standing over a grill or smoker all day.

Apple Cider Vinegar Keeps Them Tender and Bright – That splash of vinegar works during the long cook to break down the meat even further while adding a subtle tang that cuts through the richness so the ribs never taste heavy or one-note.

That Spice Rub Is Incredible – The combo of smoked paprika, cumin, chili powder, and brown sugar creates a deep, smoky-sweet bark on the ribs that tastes way more complex than the simple ingredient list suggests.

Ingredients

• 2 racks Baby Back Ribs (about 4 lb total)
• 2 tbsp Brown Sugar
• 1 tbsp Smoked Paprika
• 1 tbsp Garlic Powder
• 1 tbsp Onion Powder
• 1 tsp Chili Powder
• 1 tsp Cumin
• 1.5 tsp Salt
• 1 tsp Black Pepper
• 1.5 cups BBQ Sauce
• 2 tbsp Apple Cider Vinegar

Directions

Step 1

Remove the thin membrane from the back of each rack of ribs by loosening a corner with a paper towel and peeling it off completely.

Step 2

In a small bowl, mix together brown sugar, smoked paprika, garlic powder, onion powder, chili powder, cumin, salt, and black pepper. Rub the spice mixture generously over both sides of each rack.

Step 3

Cut each rack in half so the pieces fit in the slow cooker. Stand the rib sections upright along the inside wall of the slow cooker, meaty side facing outward, curving them to fit.

Step 4

Drizzle the apple cider vinegar over the ribs. Cover and cook on low for 7 to 8 hours or on high for 4 to 5 hours, until the meat is very tender and pulling away from the bones.

Step 5

Carefully transfer the ribs to a foil-lined baking sheet, meaty side up. Brush a generous layer of bbq sauce all over the top and meaty sides of the ribs.

Step 6

Broil on high for 3 to 5 minutes, watching carefully, until the sauce is caramelized and sticky with slightly charred edges. Let rest for 5 minutes, then slice and serve.

Pro Tips

Removing the Membrane

That thin membrane on the back of the ribs is slippery and annoying to grab, but a dry paper towel gives you the grip you need. Slide a butter knife under a corner to loosen it first, then grab that flap with the paper towel and pull it off in one steady motion.

If you skip this step, the membrane turns into a tough, chewy layer that won’t let the spice rub penetrate the meat. It also blocks the smoke flavor from the paprika, so you end up with bland ribs on one side.

How to Arrange Ribs in the Slow Cooker

Standing the rib sections upright and curving them along the wall of the slow cooker is the key move here. If you lay them flat and stack them, the bottom rack sits in liquid the whole time and gets mushy instead of tender.

When they’re standing up, hot air and steam circulate around all the pieces evenly. You want the meaty side facing the outer wall of the slow cooker because that side gets the most heat, which helps build flavor.

If you have a smaller slow cooker and the pieces are still too tall, you can cut each half-rack into two-rib sections. Just make sure nothing is packed too tight so steam can still move around.

Don’t Add BBQ Sauce to the Slow Cooker

It might seem like a good idea to pour bbq sauce in with the ribs while they cook, but don’t do it. The sugar in the sauce will break down over those long hours and turn bitter, and the flavor gets washed out by all the liquid the ribs release.

The ribs put off a surprising amount of juice on their own, so they definitely won’t dry out without sauce. Save all the bbq sauce for the broiling step at the end where it actually caramelizes and gets that sticky, glossy finish you want.

Frequently Asked Questions

Do I really need to remove the membrane from the back of the ribs?

Yes, removing the membrane makes a big difference. That thin, papery layer on the bone side of the ribs gets tough and chewy when cooked, and it also blocks the seasoning from penetrating the meat. Peeling it off is the single best thing you can do for tender, flavorful ribs.

If you’re having trouble gripping it, use a dry paper towel to get a good hold on the corner and pull it off in one smooth motion. You can also ask your butcher to do it for you when you buy the ribs.
