French Bread Grilled Cheese with Caramelized Onions and Sharp Cheddar Cheese


Do you remember a little while back when grilled cheese was all I could think about? Melty cheese on fresh french bread. It sounded so good, but it felt like something was missing. It only took me a second to realize it was caramelized onions. Yes, caramelized onions would make it perfect… and it did!


Another one of my non-recipe recipes. Got that? It’s so easy you don’t really need a recipe to make it. Just throw this on this and add this and you are done kinda recipe.

Ingredient list:

  • butter
  • 1 large onion
  • French bread
  • sharp cheddar cheese


I started with my homemade 30 minute french bread. Slice it into sandwich-sized loaves and set it aside.


Slice a large onion into big rings. Add butter to a frying pan and melt it. Add onions to the butter and caramelize them over medium heat. Cook them till they are translucent and golden brown on the edges. They will be buttery sweet.


In the same pan you caramelized the onions, add more butter and let it melt over low heat.


Time to construct the sandwiches. Take the bread and layer the rest of the ingredients onto it. Start with a thick slice of sharp cheddar cheese and a huge pile of the caramelized onions. Squish it all between both slices of bread.


Here is the fun part. Add them each one by one into the pan and grill them each on both sides till the cheese is all melted and there is a good char on each side.


That’s it! They taste best when they are eaten right away. Enjoy!

  • I am a grilled cheese kinda girl. All ways, shapes & forms. Why oh why have I never tried caramelized onions (which I love love love by the way)! Pin’d! Thank you for sharing at the Should be Mopping the Floor party =)

  • I love grilled cheese sandwiches too. My favorite food with a bowl of tomato soup.

    If you like burgers let me share with you a wonderful way to eat a burger…..use garlic bread as a bun. Take the bread and grill it in a skillet on both sides…when it is hot and warm add a cooked burger with cheese and those grilled onions. WOW….it is good.
