THE GOOD STUFF

Ingredients

LET’S MAKE IT

Step by step

  1. Warm butter and olive oil over medium-low heat in a skillet.
  2. Add onions and salt (and optional sugar); cook slowly, stirring often, 25–35 minutes until richly golden and jammy.
  3. Stir in thyme and the optional wine or broth; cook until the liquid has evaporated.
  4. Toast baguette slices until lightly crisp; arrange them on a baking sheet.
  5. Spoon caramelized onions onto the toasts and cover with Gruyère.
  6. Broil for 1–2 minutes until bubbling and golden, watching carefully to avoid burning.
  7. Finish with freshly cracked black pepper and extra thyme. Serve warm.
Make the onions ahead and broil the topped toasts right before serving.
SHOP THE SETUP

Finish with a little crunch.

A few flakes of Maldon Sea Salt can add texture after broiling, if the finished toasts need extra seasoning. Taste first—the cheese is already salty.
