Remove membranes from the back of the ribs. They should come off fairly easily by slipping a butter knife underneath the membrane and running the knife along the underside, pulling up on the membrane until you are able to detach the membrane.
Season both sides with rib rub.
Place wire rack trivet into the inner pot of an Instant Pot and add water.
Place ribs upright in a circular shape with meat facing outward and ribs inward.
Cook on high pressure for 25 minutes.
When the cycle is complete, natural release for 15 minutes, then quick release.
Carefully remove the ribs from the Instant Pot and place on a cutting board.
Brush and Bake With BBQ Sauce
Brush top of ribs with Keto BBQ Sauce.
Cut ribs as necessary and place in an air fryer for 5 minutes at 400 F. If you don’t have an air fryer, you can complete this step in an oven, although you may need to bake for a little longer (until the outside is slightly crispy).
