Preheat your oven to 300°F (150°C).
Carefully remove the thin membrane from the back of the ribs to ensure they become incredibly tender during the slow roast.
In a small bowl, mix the smoked paprika, garlic powder, onion powder, sea salt, and black pepper, then rub the mixture evenly over both sides of the ribs.
Wrap the seasoned ribs tightly in parchment paper followed by a layer of aluminum foil, then place them on a rimmed baking sheet.
Bake the ribs for 2 to 2.5 hours until the meat is tender and just beginning to pull away from the bone.
While the ribs bake, whisk together the tomato paste, maple syrup, coconut aminos, and apple cider vinegar in a small saucepan over low heat until well combined.
Remove the ribs from the oven, open the foil carefully, brush the sticky glaze generously over the meat, and broil on high for 3-5 minutes until caramelized.
Steam the green beans for 5-7 minutes until they are vibrant and tender-crisp, then serve them immediately alongside the glazed ribs.
