Halve onions from root to tip and remove root. With root facing you, slice onion halves into ⅛” to ¼” thick slices. Repeat for both onions.
Season with pinch of salt and reduce heat to medium-low. Cook onions for 15 to 20 minutes, stirring every few minutes to prevent from sticking.
Check onions for doneness. If they are getting too brown or sticking a bit, reduce heat. Cook for another 15 to 20 minutes.
If there are any bare spots in the pan, add splash of water to keep onions from burning.
Reduce heat and add Red Crown Pomegranate Reduction. Season with salt and stir to combine, cooking on low for 2 to 5 minutes until combined.
Serve and garnish with fresh pomegranate arils.
