How to Make French Onion Grilled Cheese


  1. RED ONION JAM: (I would make at least day in advance)

    Combine the onion, butter, sugar & salt in a small saucepan with a lid. Saute over medium low heat, covered, for 20 minutes, stirring occasionally.

    Uncover, add the wine & vinegar & continue to cook over medium heat, stirring slightly more frequently, until there is no liquid left & the onions are soft & caramelized, about 25 minutes.

    Let the jam come to room temperature, then transfer to an airtight container & keep in the fridge for up to 3 weeks.

    NOTE: After making would probably make enough for about 4 - 6 sandwiches depending on how much you put on each sandwich.
  2. Since the red onion jam keeps for a while in the fridge, you can make it up to 2 weeks in advance & keep it on hand for your grilled cheese making pleasures or other.
  3. SAMMIE:

    Lightly toast both slices of bread. Spread one side with the red onion jam, then pile on the shredded cheese. Sprinkle with salt & freshly ground pepper. Press the second piece of bread on top.
  4. Melt 2 tsp of butter in a small frying pan over medium low heat. Carefully place the sandwich in the pan & cook, pressing down occasionally with a spatula, until the cheese has started to melt & the bread is golden & crispy, 4 - 5 minutes. Lift it out of the pan with the spatula & add the remaining 2 tsp of butter. Flip the sandwich & return it to the pan. Cook another 4 - 5 minutes until the cheese is gooey & the second side is golden.
  5. Place on a plate, cut in 1/2 & eat immediately.
