Ingredients
  

For the dry rub
  • 1 1/2 tbsp brown sugar
  • 2 tsp chili powder
  • 1 1/2 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 1/4 tsp salt
  • 1/2 tsp black pepper
For the slather and base
  • 2 tbsp mustard (I use French’s Classic Yellow)
  • 2 tbsp honey
  • 1 onion (halved and sliced into 1/2-inch thick moons)
  • 1 cup water
  • 1 tbsp apple cider vinegar
For the ribs and finishing
  • 3 lb ribs (I prefer Smithfield St. Louis Style ribs for better fat marbling)
  • 3/4 cup bbq sauce (Sweet Baby Ray’s works best for a thick glaze)

Method
 

  1. Combine the brown sugar, chili powder, smoked paprika, garlic powder, onion powder, salt, and black pepper in a small bowl, mixing thoroughly to ensure the spices are evenly distributed. In a separate bowl, whisk together the mustard and honey until smooth and well combined. These two mixtures will form the flavor foundation for your ribs. I like to make the dry rub the night before and store it in an airtight container—the flavors meld together and become more potent.
  2. Preheat your oven to 300°F. Pat the ribs completely dry with paper towels—this helps the rub adhere better. Remove the thin membrane from the back of the ribs by sliding a knife under it and peeling it away; this allows the spices and moisture to penetrate the meat during cooking. Slice the onion into ½-inch thick moons and set aside. Once the oven reaches temperature, you're ready to build the braising liquid.
  3. Pour the water and apple cider vinegar into a large roasting pot or Dutch oven and arrange the sliced onions on the bottom to create a flavorful bed. This liquid will braise the ribs low and slow, keeping them incredibly moist. Generously coat both sides of the ribs with the honey-mustard mixture from Step 1, then apply the dry rub mixture, pressing it gently so it adheres to the meat. Cut the ribs into 2-3 manageable sections and place them bone-side down on top of the onions.
  4. Cover the pot tightly with foil or a lid to trap the steam and moisture, creating a humid braising environment that keeps the ribs tender. Place in the preheated 300°F oven and braise for 3 hours undisturbed. The low temperature and braising liquid will render the fat and break down the connective tissue, resulting in fall-off-the-bone ribs. I find that resisting the urge to peek keeps the temperature stable and ensures even cooking.
  5. Remove the ribs from the oven and carefully brush both sides with the BBQ sauce, coating evenly. Heat a grill or cast-iron skillet over medium-high heat, then gently place the ribs on the hot surface and sear all sides for 2-3 minutes per side until the sauce caramelizes and forms a deep, glossy crust. This quick searing step adds a charred exterior and locks in the glaze. Watch carefully to prevent burning—the sauce can char quickly, so move the ribs frequently if needed.
