Ingredients

2 ½ tablespoon unsalted butter
1 tablespoon olive oil
2 large yellow onions
¼ teaspoon salt
2 tablespoon water, wine, or beer for deglazing the pan

Instructions

Melt the butter and olive oil over medium-low heat.
Add the onions and sprinkle with salt. Cook uncovered over low heat for 45-60 minutes until golden or deep golden brown. Stir occasionally to avoid burning or sticking. You will need to stir more frequently towards the end of the process.
In the last few minutes, deglaze the skillet by adding the liquid of your choice while scraping the bottom of the pan with a wooden spatula. Serve on burgers and enjoy.
