Before you start

Before starting, ensure your slow cooker insert is clean and dry. Remove the ribs from their packaging and pat them dry with paper towels to improve the adhesion of the sugar. Peel and slice the sweet onion into uniform rounds, about a quarter-inch thick.

Measure out your brown sugar and whiskey so they are ready to add immediately after the ribs are positioned. Having all ingredients prepped beforehand makes the assembly quick and prevents unnecessary mess in the kitchen.

Ingredients at a glance (4)
  • 3 lb pork spareribs, cut into serving-size sections
  • 1 large sweet onion, sliced into rounds
  • 1 cup dark brown sugar
  • 1/2 cup whiskey

Instructions

Assembly and layering

  1. Assemble the ribs
    Place the pork spareribs into the slow cooker, standing them on edge to fit them snugly. Tuck the sliced sweet onion rounds in between the ribs to ensure even flavor distribution throughout the cooking process.
    Look for Ribs are standing upright and onions are tucked in.
    Tip Packing the ribs tightly helps them cook evenly in their own juices.

At the end of this phase, the ribs should be standing upright, snugly packed within the slow cooker. The onion slices should be distributed evenly between the rib sections to ensure they soften and release their flavor throughout the cooking cycle. Ensure the base of the insert is clear of any debris so the ribs sit flat on the bottom of the stoneware.

Adding the glaze

  1. Add glaze ingredients
    Evenly spoon the dark brown sugar over the top of the ribs. Pour the whiskey over the sugar and the ribs, ensuring everything is lightly coated. Cover the slow cooker with its lid.
    Look for Sugar is distributed and whiskey is poured over.
    Tip Pouring the whiskey slowly helps dissolve the sugar as it reaches the bottom.

Once the brown sugar and whiskey are added, the ribs should be lightly coated. The sugar will begin to dissolve as it hits the whiskey, creating a base for the glaze. Check that the sugar is spread evenly across the tops of the ribs rather than clumped in one spot, which helps in creating a consistent flavor profile as the sugars caramelize during the slow cook.

Slow cooking to perfection

  1. Slow cook and serve
    Cook on low for 8 hours until the meat is opaque and pulling away from the bones. Check that the internal temperature reaches at least 145°F (63°C). Let the ribs rest for 5 minutes before serving with the sauce.
    Look for Meat is tender and pulls away from the bone.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Use tongs to carefully lift the ribs as they will be very tender.

After the long cook, the ribs should look tender, with the meat shrinking slightly away from the ends of the bones. The liquid at the bottom of the cooker will have transformed into a rich, dark amber sauce.

The onions should be completely soft. Check the temperature and ensure the meat is fully cooked through before turning off the slow cooker and letting the ribs rest.

Common mistakes

Avoid lifting the slow cooker lid frequently during the cooking process, as this releases heat and steam, which significantly increases the total cooking time and can lead to uneven results. Do not overcrowd the slow cooker; if the ribs are packed too tightly, the heat will not circulate properly.

Conversely, do not add too much liquid, as the onions and the pork itself will release moisture during cooking, which would dilute the glaze and prevent it from becoming properly sticky and rich.

How to tell it’s done

The ribs are perfectly done when the meat is opaque and begins to pull away from the bone, indicating that the connective tissues have broken down. Use a meat thermometer to ensure the internal temperature of the thickest part of the ribs reaches at least 145°F (63°C).

The sauce should have thickened into a pourable, amber glaze. Allow the ribs to rest for at least 5 minutes before serving to ensure the juices redistribute throughout the meat, maximizing tenderness.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
