Creating the Ultimate Bacon Sandwich
Now for the fun part! Follow the steps below, and you’ll be devouring a perfect bacon sandwich in no time.
Caramelize Those Onions
To get that sweet, golden flavor, start with the onions. Heat olive oil and butter in a skillet over medium-low heat. Add your thinly sliced onions, and stir gently. Patience is key here! Cook for about 20–30 minutes, stirring occasionally, until the onions soften and turn golden brown. The smell alone is worth it!
Crisp Up the Bacon
While the onions do their magic, grab a separate skillet and lay down the thick slices of bacon. Fry them to your desired crispness (soft and chewable or crunchy perfection, it’s your call). Once done, drain the bacon on paper towels to remove excess grease.
Toast & Assemble the Sandwich
Next, toast your bread slices until golden. Spread each slice with your favorite condiment; mayonnaise, mustard, or even ketchup could work. Start stacking with caramelized onions as the foundation, add your crunchy bacon, and pile on extras like lettuce or tomato if you like. Close the sandwich with the second slice of bread. Presto, you’re done!

Pro Tips for a Perfect Sandwich
- For deeper flavor, deglaze the onion skillet with a splash of red wine or broth.
- Try cooking bacon in the oven for less mess and evenly crispy results.
- Toasting the bread on a frying pan with a little butter makes it extra luxurious.
- Allow onions to cook slowly without rushing to achieve a proper caramelization (sweet, not burnt!).
Serving Suggestions for This Delightful Sandwich
Presentation is everything! Try slicing the sandwich diagonally for a chic touch. For sides, pair it with crispy potato chips, a light salad, or even a bowl of velvety tomato soup. A sprinkling of fresh parsley or a dollop of aioli can also jazz it up beautifully!

Plan Ahead and Store Smartly

Storing the Components
Caramelized onions store beautifully in an airtight container for up to a week in the refrigerator. Bacon can be cooked ahead and reheated.
Freezing Option
Although fresh is always better, you can freeze pre-cooked bacon and caramelized onions. Place them in separate freezer bags, and thaw in the refrigerator when needed.
Shelf Life
While assembled sandwiches are best enjoyed fresh, their components last well. Just quickly assemble before serving to keep bread crisp!
