The slow cooker is a wonderful tool for effortlessly cooking onions to a deep brown color and silky tenderness.


  • 2 pounds (910 g) onions
  • Salt and freshly ground black pepper
  • 4 cups (960 ml) good-quality beef stock
  • 1 tablespoon tomato paste
  • 1 tablespoon miso paste
  • 1 bay leaf



Cut the onions into quarters, then slice the quarters crosswise ½ inch (6 mm) thick. Put them in the slow cooker and toss with 1 teaspoon salt and several grindings of pepper. Add the stock, tomato paste, miso paste, bay leaf, and 1 cup (240 ml) water. Cover and cook on low for 8 hours.


Season with more salt or pepper, if needed, then serve.
