There is nothing like the aroma of butter fried onions. Delicious with so many foods.
Peel the outer skin off the onion.
Use a sharp knife to thinly slice the onions.
Let the onions sit for at least 5 minutes before cooking.
Heat 4 tablespoons of the broth in a cast iron pan (or any type of skillet) over medium heat.
As soon as the broth begins to steam, add the sliced onions and cover for 3 minutes.
The onions will release a small amount of liquid.
Uncover, and the remaining 4 tablespoons of broth.
Leave the lid off and cook for another 4 minutes.
Cook for 7 minutes, until the onions are translucent, depending on the thickness of the slices.
For more tender onions, cook for 2 to 3 more minutes longer, uncovered, and stir frequently.
Shut off the heat and while the onions are still hot, stir in the oil, and salt and pepper to taste.
