These are delicious on grilled hamburgers, bratwurst or “veggie burgers” .
Yield: ½ cup
2 large sweet yellow onions, I prefer Vidalia
3-4 tablespoons unsalted butter
3-4 tablespoons vegetable oil
¼ teaspoon cayenne pepper
Thinly slice the onions and separate them into rings and rough chop. In large skillet, cast iron preferred, melt butter and oil together. Add the onions to the butter and oil and cook over medium heat for about 10-15 minutes, stirring constantly until they start to soften. Reduce heat to low and cook for another 15-20 minutes, until the onions are caramelized and deep brown. Remove from skillet and drain on paper towels to absorb excess oil.
