Caramelized onions make a delicious addition to so many dishes. Sweet and savory, caramelized onions take such a basic ingredient to a whole new level!
Heat skillet or saute pan over low-medium heat. Add butter or olive oil to skillet. Separate onion slices into rings and add to your skillet. Watch onions to make sure they are cooking low and slowly, adjusting the temperature as needed. Stir only occasionally. Cook until onions have reached desired coloring, between 30-50 minutes. Remove from heat and serve.
