Bacon, Caramelized Onion and Chipotle Aioli Sandwich

Bacon, Caramelized Onion and Chipotle Aioli Sandwich

Sandwiches deserve a little more press. I’m not talking about peanut butter and jam sandwiches (which I love), or cheddar cheese and tomato sandwiches (which I also love), but sandwiches that make you stop what you are doing and give them your full attention.

To help out the sandwich’s lowly reputation, I’ve decided to feature it in a six part Sandwich Series. Like the title? That idea was mine and mine alone. I know I know, alliteration is cheesy, but this first sandwich needed a little cheese. Ok that was really bad. I’ll stop.

Bacon, Caramelized Onion and Chipotle Aioli Sandwich

Inspired by Simone’s comment on my Chipotle Sea Salt post about how she mixes chipotles in mayonnaise, I knew I had to whip up a batch. The bacon and caramelized onions seemed like the only logical things that belonged with chipotle aioli on a sandwich.

This is a messy, gooey, don’t-ever-eat-on-a-first-date kind of sandwich. It is finger-licking, lip- smacking, I-don’t-care-how-many-calories-are-in-here kind of good. It is rich from the bacon, sweet from the caramelized onions and spicy from the chipotles. I just finished eating the one here and when I looked down at my plate (actually I ate it right off the table where I photographed it) to see it was all finished, I felt a pang of sadness. I wanted more. Lots more.

Bacon, Caramelized Onion and Chipotle Aioli Sandwich
Prep time
Total time
Rich, sweet, spicy and oh so deliciously messy.
Recipe type: Sandwich
  • Two slices of bread per sandwich
  • Bacon, cooked
  • Caramelized onions, cooked in the leftover bacon fat (of course)
  • Thinly sliced tomatoes
  • Parsley
  • Aioli with chopped chipotles in adobo sauce
  1. I’ve given no measurements on purpose, nor directions. I think everyone knows how to assemble a sandwich. If, for some reason I cannot possibly imagine, you do not, put all the ingredients between the two slices of bread. As for how much, I’ll let you decide; you know your tastes best. For my one sandwich I used 4 slices of bacon, ½ an onion, a few slices of tomato, a handful of parsley and more chipotle aioli than I’ll ever admit to.
  2. Enjoy!

    “sandwiches that make you stop what you are doing and give them your full attention”

    I’m glad to find someone who feels the same way I do about sandwiches. Great recipe, I’ll try it soon. Thanks for a great website.

    Instead of bacon I also like to fry up pieces of prosciutto. They get crispy and salty and I LOVE BACON, but also they are not as fatty as bacon.

      I love crispy prosciutto too. I had it for the first time this summer on a caesar salad. It was so delicious!

    You’ve done it again… you made me drool on my keyboard… :) Love the look of that sandwich and as it so happens, I still have some chipotle left in the fridge (good thing it keeps forever!) and some really nice sourdough bread that I am gonna be baking for lunch… Guess what will be on it?

      Thanks Simone! Your comments always put a smile on my face. The whole reason I am doing this whole blog thing is so that people will, well, ‘drool on their keyboards.’ :) Best compliment ever!
