Ingredients

  • 2 pre cooked short ribs with bone in
  • 1/3 cup of gruyere cheese shredded
  • 1 small white onion sliced
  • 1 tbsp of balsamic vinegar
  • 1 tbsp of olive oil
  • 1 tbsp of butter
  • Kosher salt to taste

Instructions

  • For Caramelized Onions (cook time 30 minutes)
  • In a small cast iron skillet, add olive oil and butter on medium heat
  • Once butter is melted, add sliced onions to the skillet and cover with a tight fitting lid
  • After about 3 minutes, remove the lid and give onions a stir
  • Continue this process for the next 20 minutes stirring every 5 minutes or so
  • Onions will begin to brown and become fragrant
  • At the end of cooking right when the onions begin to caramelize add kosher salt and balsamic vinegar
  • Give a final stir and remove the heat and set aside
  • To assemble skillet (prep 5 minutes, cook time 5 minutes)
  • In a small cast iron skillet, add 2 pieces of short ribs bone side down
  • To each short rib, top with a heaping of caramelized onions to taste and add shredded gruyere cheese
  • Broil in the oven until cheese is melted and bubbling, about 2-3 minutes (keep your eyes on it)

Notes

Cook time is a combination of the time it takes to caramelize the onions and the time it takes to prep the skillet and melt the cheese in the oven. Caramelization of onions takes about 30 minutes. To assemble the skillet and then melt the cheese should be about 10 minutes total.
If you want you can add a little bit of the short rib liquid to the bottom of the skillet to help steam and reheat your short ribs if you're warming them up, just enough to create a little steam and warm the short ribs through.
