Ham and Caramelised Onion Grilled Cheese

Who doesn't love caramelized onions? Especially in a ham and caramelized onion grilled cheese sandwich, where the slight tartness is a perfect complement to our bold Extra Old Cheddar Cheese. This quick-to-prepare recipe is sure to become one of your classics.


  • 2 white medium onions, peeled
  • 15 mL (1 tbsp) extra virgin olive oil
  • Pinch dry thyme or 1 branch fresh thyme
  • 1 mL (1/4 tsp) white sugar
  • 125 mL (1/2 cup) water
  • 10 mL (2 tsp) white wine vinegar
  • 8 slices crusty whole wheat, thickly sliced bread
  • 45 mL (3 tbsp) Dijon mustard
  • 225 g (1/2 lb) sliced ham
  • 12 slices Armstrong Extra Old Cheddar Cheese, sliced (1/2”, 1cm)
  • 45 mL (3 tbsp) salted butter


  1. Slice onions 1/2 cm (1/4” thick). In a frying pan on medium-high heat fry the onions in olive oil for 2 min. Add thyme and sugar. Continue frying, stirring often for 15 minutes, until golden. Add water and cook until evaporated. Add vinegar, stir and cool.
  2. Cut cheddar in 12 slices.
  3. Spread 4 slices of bread with mustard. Divide the ham, Armstrong Extra Old Cheddar Cheese, and onions between the slices. Top with more bread, spread top of each sandwich with 5 mL (1 tsp) butter.
  4. In a large frying pan on medium-low heat fry 2 sandwiches butter side down for 4 minutes, until golden. Spread top of each sandwich with 5 mL (1 tsp) butter, flip and cook another 3 minutes. Repeat with remaining sandwiches. Serve.


*Serve with a bowl of soup to make a comforting and delicious lunch. Try adding sliced tomatoes or pickles to the sandwiches before cooking.
