1Bring a pot of water to a boil over medium high heat. Cut the onions halfway through the center and boil for 15 minutes until they start to slightly soften.
2Remove the onions from the water and let them cool for a few minutes. Remove the first 4-5 layers of each onion to make dolma and chop the inner ones and set aside.
3Make the filling by mixing rice, ground beef, garlic, parsley, mint, Aleppo pepper, allspice, oregano, salt, pepper, tomato paste, pepper paste, pomegranate molasses, and olive oil in a bowl.
4Preheat the oven to 375 degrees F.
5Fill each onion layer with 1 to 1 1/2 tablespoon filling, gently roll it up so the ends overlap and nestle tightly next to each other in a baking dish (ceramic).
6Make the sauce by mixing the tomato paste with hot water, pomegranate molasses, olive oil, salt and pepper.
7Pour over the dolmas and cover with aluminum foil.
8Bake for 45 minutes. Then, uncover and bake for another 30 minutes until the sauce is reduced and the onions are golden.
