Cut the rack of ribs in thirds so that the ribs can lay flat in the crockpot later! Place the three pieces in a large resealable freezer bag.
Sprinkle with salt & pepper.
Dump in 2 cups of BBQ sauce. Pour in Dr. Pepper and squish to combine.
Remove excess air from the bag, seal, and freeze.
Cooking instructions:
Thaw.
Place the ribs in the crockpot.
Cook on high for 4 hours or on low for 8 hours.
Remove from the slow cooker once the ribs are fully cooked.
If desired, top with some additional BBQ sauce before serving.
Notes
Pro tip: If you want, you can whip up a small batch of the extra sauce by mixing an additional 1/2 cup of BBQ sauce with 1 additional Tbsp. of Dr. Pepper. Freeze the extra sauce in a medium freezer bag. Staple that bag to the other bag above the seal. You can use this sauce when serving.
