Instructions

For the Ribs:

    2 rack St. Louis-cut pork ribs
  • In a small bowl, combine all of the dry rub ingredients and stir to mix evenly.
    2 tablespoon kosher salt, 1 tablespoon brown sugar, 1 tablespoon smoked paprika, 1 tablespoon garlic powder, 1 tablespoon onion powder, 2 teaspoon black pepper, 1 teaspoon chili powder, ½ teaspoon cayenne
  • Pat the ribs dry and brush each side with mustard, about one tablespoon per side.
    ¼ cup yellow mustard
  • Apply the rub evenly to all sides of the ribs, pressing lightly to adhere the dry rub to the mustard.
  • Let the ribs sit at room temperature for 30-45 minutes, or refrigerate overnight uncovered.

Bake the Ribs

  • Preheat the oven to 275°F (135°C).
  • Place the ribs meat-side up on a wire rack set over a large sheet tray.
  • Bake for two and a half to three hours, or until the ribs are tender but not falling apart. The meat should have pulled back from the bones by about ½ inch (one centimeter).
  • Remove the ribs from the oven and place each rack on a large sheet of aluminum foil.
  • Divide the apple juice, melted butter, brown sugar, and apple cider vinegar between the racks.
    ½ cup apple juice, 4 tablespoon melted butter, 2 tablespoon brown sugar, 1 teaspoon apple cider vinegar
  • Wrap the foil tightly around the ribs to seal in the steam.
  • Return to the oven and cook for another one to one and a half hours.

For the BBQ sauce:

  • While the ribs cook, combine all BBQ sauce ingredients in a medium saucepan.
    1 cup ketchup, 1 cup chicken stock, 1/4 cup brown sugar, 2 tablespoon molasses, 2 tablespoon apple cider vinegar, 1 tablespoon Worcestershire sauce, 1½ teaspoon yellow mustard, 1/2 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon black pepper, 1/4 teaspoon kosher salt, 1/4 teaspoon chili powder, ⅛-¼ teaspoon cayenne, 1 bay leaf
  • Cook over medium heat for 20-30 minutes, stirring occasionally, until thickened.
  • Carefully unwrap the cooked ribs and transfer them back to the baking sheet bone-side up.
  • Measure ½ cup (120 milliliter) of the rib drippings and stir them into the BBQ sauce.
  • Simmer the sauce over low heat for 10 minutes.

Finish and serve:

  • Brush the ribs with BBQ sauce on all sides. Finishing with the meat side up.
  • Increase the oven temperature to 425°F (218°C).
  • Cook ribs for 10-15 minutes, until the sauce is glossy, sticky and lightly caramelized.
  • Let ribs rest 10 minutes before slicing between the bones and serving.

Notes

*Adjust the ingredient amounts in the recipe instructions accordingly if doubling or tripling the recipe. 
  • For the best flavor, season the ribs and refrigerate them uncovered overnight before cooking.
  • St. Louis-style ribs are done when they are tender with a slight bite and reach an internal temperature of 200-203°F (93-95°C).
Storage:
- Refrigerator: Transfer cooled ribs to an airtight container, and store them in the refrigerator for up to four days. 
- Freezer: Freeze cooled ribs for up to three months. Wrap individual portions or whole racks tightly in plastic wrap and aluminum foil, then place them in a freezer-safe container or zip-top bag.
- Reheating: Reheat ribs covered with foil in a 300°F (150°C) oven for 20-30 minutes if thawed or 45-60 minutes from frozen, until heated through. For the best texture, brush with a little extra barbecue sauce before reheating. Avoid microwaving when possible, as it can dry out the meat and soften the bark.
