Three ingredients, zero babysitting. These pork ribs slow cook for 6 hours until the meat pulls clean off the bone. Carnivore and keto friendly.
I make these slow cooker pork ribs when I want something hands-off for dinner. Three ingredients go into the crock pot in the morning, and by evening, the meat is falling off the bone without any effort in between.
The method is simple. Season a rack of pork ribs with salt and pepper, pour apple cider vinegar into the bottom of the slow cooker, and stand the ribs upright along the liner. The vinegar does two things: it creates steam that keeps the meat moist during the long cook, and the acidity helps break down the connective tissue faster. You will not taste vinegar in the finished ribs. It cooks off completely.
Standing the ribs upright (meaty side pressed against the liner) is the key detail most slow cooker rib recipes skip. That direct contact with the hot ceramic gives you a slight caramelization on the outside of the meat. You will not get a bark like you would from a smoker, but the exterior develops more color and texture than ribs that sit flat in liquid.
This recipe is naturally carnivore and zero carb. No sauce, no sugar rub, no hidden ingredients. If you follow a keto dinner rotation or strict carnivore protocol, these ribs fit without any modifications.
For sides, I usually pair these with keto coleslaw or cauliflower mac and cheese. If you want a sauce on the table, my keto BBQ sauce works well for dipping (though the ribs honestly do not need it). A batch of keto cornbread rounds out the plate if you are feeding a crowd.
I have tested this with both baby back ribs and St. Louis style spare ribs. Baby backs are leaner and cook a bit faster (closer to 5 hours on low). St. Louis style spare ribs have more fat marbling and benefit from the full 6 hours. Either cut works in this recipe. Ask your butcher to remove the membrane if you do not want to do it yourself, though the process takes less than a minute once you get the technique down.
One note on the seasoning: I keep it to salt and pepper for a true carnivore approach. If you are not strict carnivore, garlic salt or a simple dry rub with paprika, garlic powder, and onion powder adds another layer of flavor without adding carbs.
How to make slow cooker pork ribs
Start by removing the membrane from the back of the ribs. Slide a butter knife under the membrane near one end to create a pocket, then grip it with a paper towel and pull it off in one motion. This step is optional, but removing the membrane lets the seasoning penetrate both sides of the ribs and gives you a more tender result.
Season all sides generously with salt and pepper. Pour half a cup of apple cider vinegar into the bottom of the slow cooker liner.
Stand the ribs upright in the crock pot with the meaty portion pressed against the liner wall. This positioning gives the outside of the meat more direct heat contact, which creates better color and texture on the surface. Cook on low for 6 hours.
The ribs are done when the meat pulls away from the bone with no resistance. If you want to add a finishing glaze, brush the ribs with keto BBQ sauce and broil them for 2 to 3 minutes in the oven. Serve with keto green beans and bacon or your favorite low carb side.

Step by Step Instructions
Remove the membrane
Remove the membrane of pork ribs if needed or desired. To do so, take a butter knife and slide it under the membrane next to the ribs to form a pocket. Then slide two or three fingers under the membrane to create more space. Using a paper towel for grip, hold onto the membrane with the paper towel and pull off the membrane until it is completely removed. (See below for further instructions.)
Add ribs
Add pork ribs to the liner of the slow cooker. Let the ribs sit upright on its edge with the meaty portion up against the liner. This will help give the ribs a nice golden crispy exterior.

Can I use other types of meat instead of pork ribs?
Beef short ribs work well with this same method. Cook them on low for 8 hours since they have denser connective tissue. Bone-in chicken thighs are another option, but reduce the cook time to 4 hours on low to avoid the meat falling apart completely. Keep the apple cider vinegar at half a cup regardless of the protein you use.
What can I use instead of apple cider vinegar?
White vinegar works as a direct substitute at the same amount. You can also use a mix of lemon juice and water (2 tablespoons lemon juice plus enough water to reach half a cup). The vinegar cooks off completely during the 6 hours, so the final flavor difference between types is negligible.
How long should I cook the ribs in the slow cooker?
Cook on low for 6 hours for baby back ribs or 6 to 8 hours for spare ribs. You can also cook on high for 3 to 4 hours, though low and slow produces a more tender result. The ribs are done when the meat pulls away from the bone with no resistance and you can see about a quarter inch of bone exposed at the ends.
How should I store leftovers?
Store leftover ribs in an airtight container in the refrigerator for up to 4 days. They freeze well for up to 3 months. To reheat, wrap the ribs in foil with a splash of water and warm them in a 300 degree oven for 15 to 20 minutes. The microwave works in a pinch, but the oven preserves the texture better.
Do I need to remove the membrane from the ribs?
Removing the membrane is optional but recommended. The membrane is a thin, translucent layer on the back (bone side) of the rack. If you leave it on, it can turn rubbery during the slow cook and prevent seasoning from reaching the underside of the meat. To remove it, slide a butter knife under the membrane near one end, grip it with a paper towel for traction, and pull it off in one motion. Most butchers will do this for you if you ask.
Can I make these ribs in the oven instead?
Yes. Season the ribs the same way and place them on a wire rack set over a sheet pan. Pour the apple cider vinegar into the bottom of the pan. Cover tightly with foil and bake at 275 degrees for 3 to 4 hours. Remove the foil for the last 15 minutes if you want a drier, slightly crispy surface. The slow cooker is more hands-off, but the oven produces similar results.
These slow cooker pork ribs are a filling dinner when I don’t have time to cook at night. I just place a rack of ribs in the crock pot and cook on low for several hours.
The ribs turn out tender and juicy with just two seasonings: salt and apple cider vinegar.
To remove the membrane from a rack of pork ribs,
I don't think you want to be using a plastic spray bottle with vinegar. Like making broth, the vinegar will pull out toxic chemicals from the plastic and put it in the liquid you are spraying on your food.
If you want collagen in your food, don’t remove the membrane - eat it.
Thank you for that tip!! I'm new to carnivore.
