Learn how to make delicious Caramelized Onion Bacon Grilled Cheese Sandwich. Easy recipe with step-by-step instructions.

Ingredients

Scale

Gathering the right ingredients is key to making this sandwich truly exceptional. Here’s what you’ll need:

  • 8 slices of sourdough bread
  • 2 tablespoons unsalted butter, softened
  • 1 large onion, thinly sliced
  • 1 tablespoon olive oil
  • 8 slices of thick-cut bacon
  • 8 ounces of cheddar cheese, sliced
  • 4 ounces of Gruyère cheese, sliced
  • Salt and pepper, to taste

Feel free to substitute the Gruyère with Swiss cheese for a more budget-friendly option. My grandma often used what she had on hand, and it always turned out delicious.

Instructions

Ready to dive into making this comfort food classic? Here’s how:

  1. Start by caramelizing the onions. In a large skillet, heat the olive oil over medium heat. Add the sliced onions and season with a pinch of salt. Cook for about 25-30 minutes, stirring occasionally, until they become golden brown and caramelized.
  2. While the onions are cooking, prepare the bacon. In another skillet, cook the bacon over medium heat until crispy. Once done, place on a paper towel-lined plate to drain excess grease.
  3. Butter one side of each slice of sourdough bread. Lay the buttered side down on a cutting board or plate.
  4. On the unbuttered side of four slices, start layering: add a few slices of cheddar and Gruyère cheese, a generous spoonful of caramelized onions, and two slices of bacon.
  5. Top with the remaining slices of bread, buttered side up.
  6. Heat a large skillet or griddle over medium heat. Place the sandwiches in the skillet, cooking each side for about 3-4 minutes, or until the bread is golden brown and the cheese has melted.
  7. Flip carefully and cook the other side. Press down lightly with a spatula to ensure even cooking.
  8. Remove from the skillet, slice in half, and serve immediately. Enjoy the gooey, savory goodness!

As you cook, remember my grandma’s golden rule: patience is key. Letting the onions properly caramelize and the cheese fully melt will make all the difference.
