Preheat your oven to 300°F (150°C) and line a small baking sheet with parchment paper or foil.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper to create the dry rub.
Pat the baby back ribs dry with a paper towel and evenly coat all sides with the dry rub mixture.
Wrap the seasoned ribs tightly in aluminum foil and place them on the baking sheet.
Bake the ribs for approximately 2 hours, or until the meat is tender and begins to pull away from the bone.
While the ribs bake, whisk together the tomato paste, apple cider vinegar, coconut aminos, liquid smoke, and maple syrup in a small saucepan over low heat for 5 minutes until thickened.
Carefully remove the ribs from the oven, open the foil, and brush the homemade BBQ glaze generously over the top of the meat.
Adjust the oven to the broil setting and place the glazed ribs back inside for 3 to 5 minutes until the sauce is bubbly and slightly charred.
Steam the green beans for 5 to 7 minutes until bright green and tender-crisp.
Let the ribs rest for 5 minutes before slicing and serving alongside the steamed green beans.
