How to Make Sweet Red Onion Sauce

  1. Thinly slice 2 large red onions into rings.
  2. Melt 4 tablespoons of butter (or olive oil for vegan option) in a large saucepan over medium heat. Add the onion rings and cook, stirring occasionally, until softened and caramelized (about 20-25 minutes).
  3. Pour in 1/2 cup ruby port wine, 1/4 teaspoon salt, and freshly cracked black pepper to taste.
  4. Reduce heat to low and simmer gently, stirring occasionally, until the port wine has reduced by about half and the sauce has thickened slightly (about 15-20 minutes).
  5. Taste and adjust seasoning as needed. Serve warm or cold, garnished with freshly cracked black pepper.
