Caprese Sandwiches with Balsamic Reduction

Total Shares 247

This is one of those sandwiches that screams Summer.

The other day I walked into this bakery and was beholden-ed by some of the most beautiful and enticing loaves of bread I have seen in a while. They were all something special and made with great care but it was the Ciabatta loaf that really caught my eye. It was begging me to buy it and make it into sandwiches. It just looked so perfect – crusty on outside but soft and airy on the inside, long and just flat enough to properly sandwich the ingredients I had in mind without overpowering them with too much dough.

I immediately knew I had to pick up some fresh mozzarella and basil since I had tomatoes, organic baby spinach, decent balsamic vinegar to reduce and the handful of other ingredients needed to make my signature Summer Caprese Sandwiches with Balsamic Reduction and Spinach.

This sandwich is all about layering the flavors, the right bread and reducing the Balsamic Vinegar. You want to spend the 10-minutes it takes to reduce the vinegar because it has an intense, yet amazing flavor, doesn’t drip out of the sandwich and leaves you with a tangy dipping sauce to adorn your sandwich. Trust – this is the best part. You have to do it.


  • This sandwich is all about good bread, so my suggestion is to look for a soft and airy loaf with a crisp crust that isn’t too dense. Ciabatta was my choice, but I also think a nice Baguette or Peasant Bread would be fantastic.
  • Try to get the best tomatoes you can. I normally use Heirloom but was out and chose Beefsteak. They were good but the Heirloom or Roma make this great!
  • You can make the Balsamic Reduction ahead of time – even a couple of days. If you do, it makes assembling these sandwiches a 5-minute event, which is fabulous when you are feeding hungry people.

    Another delicious recipe! Made these for lunch today and I just have to say I’m SO glad I found your blog. Been doing WW since January and was starting to find most recipes too “processed” for my liking. Making your oven fried chicken tonight and hummus tomorrow. Thanks Alyssa!

      Awesome!! Thank you Sara – that means a lot and is EXACTLY why I started Everyday Maven in the first place! Enjoy the chicken – that is one of our all-time favorites around here :)

    These were so good!!! I found ciabatta rolls that were 2 oz each (take and bake kind) so that made for easy portion control. Yum. I calculated them as 12 pps with 4 oz of bread (two rolls) and 2 oz of cheese.

    OMG, this is my FAVORITE sandwich. There’s something so decadent, yet simple to the combination of mozzarella, basil, tomato, rustic bread, and balsamic vinegar. It’s simply divine. Thanks for the reduction instructions! :)

      Good bread is awesome. I am tinkering with stopping by the bakery for another Ciabatta loaf for more sandwiches. It’s too hot for cooking tonight!

      Someday when I have more room and have tens of heirloom tomato plants, I imagine that I will be doing just that 😉
