Peel the onions; cut the onions in half and slice into thin strips.
In a large pan or cast iron skillet, over medium-high heat, melt butter and oil.
Add onions and stir with a wooden spoon to coat; reduce heat to medium or medium-low.
Let the onions cook, stirring occasionally, while the onions slowly caramelize.
After 10 minutes, season the onions with a little salt.
The onions will soften and release liquid as they gradually brown.
If the onions start to stick to the pan, add a tablespoon or two of water and stir to keep the onions from burning.
The onions should be caramelized to a nice, deep brown; between 30 to 45 minutes.
