Preheat the oven to 400 degrees F.
Combine the spinach, feta, ricotta, scallions, parsley and garlic in a bowl. Season with salt and pepper. Cut the Brie in half through the equator. Place the filling in the center of the cheese and top with the other half.
Lay 1 sheet of phyllo onto a work surface and brush with butter. Lay another sheet down and turn it slightly, keeping the center point. Brush with butter. Repeat to make a complete wheel with the last sheet. Brush with butter. Place the cheese wheel in the center of the phyllo and wrap the phyllo, twisting the top vertically. Some pieces may crumble.
Brush with more butter and transfer to a roasting rack on a baking sheet. Bake until caramelized, about 20 minutes. Allow to rest on a cooling rack for another 15 minutes before serving.
