Timing
Making the Best Bacon Sandwich with Caramelized Onions takes about 10 minutes for preparation and 20-25 minutes for cooking.
Instructions
Step 1: Caramelize the Onions
- Heat the Pan: In a large skillet, heat the olive oil and butter over medium heat.
- Add Onions: Once the butter is melted, add the thinly sliced onions. Season with a pinch of salt and pepper.
- Cook Slowly: Cook the onions slowly, stirring occasionally, for about 15-20 minutes until they are soft, golden brown, and caramelized. If they start to stick, you can add a splash of water to deglaze the pan.
Step 2: Cook the Bacon
- Cook Bacon: In a separate skillet, cook the bacon over medium heat until crispy, about 5-7 minutes. Flip halfway through for even cooking.

- Layer Ingredients: On one slice of bread, layer the crispy bacon, caramelized onions, and a slice of cheese. Add any optional toppings, such as lettuce or tomato.
- Top and Grill: Place another slice of bread on top. If you prefer, you can grill the sandwich in the skillet for a couple of minutes on each side until the cheese melts and the bread is golden brown.
Step 4: Serve
- Slice and Enjoy: Cut the sandwich in half and serve warm. Enjoy your delicious bacon sandwich with caramelized onions!
