This pesto tuna baguette sandwich is the perfect summer sandwich. Fresh basil pesto mixed with olive oil canned tuna and piled high on a baguette with arugula and hard boiled eggs.

Growing up the only fish I would eat was canned tuna or fish sticks.
That was it.
My dad would come home with beautiful fish filets he caught that day and I was all “NOPE! It’s not from a can or frozen in a box.” I was such a temperamental kid.
Although, I’m just as temperamental as an adult as well. I still don’t eat a lot of fish BUT I’m all about canned tuna.
I love how easy it is to bust open the can and in no time I’m sitting down to lunch.
Although back in the day I was just using canned tuna in water.
Little did I know canned tuna in olive oil is where. it’s. at.

Now, normally when I make tuna salad I go all traditional.
I throw in green onions, celery, and just a touch of mayo. It’s classic and totally delicious.
However, this time, around I went a bit different.
I wanted to try something that was packed full of flavor but not the same old tuna salad.

So, with that, the pesto tuna baguette sandwich was born.
Full of fresh basil flavor and piled high on a crusty baguette with spicy baby arugula and perfectly cooked hard boiled eggs.
This sandwich is so easy you’ll be thinking to yourself “why haven’t I been making this my whole life?!?!”

Tuna is a staple in my pantry! Love just throwing any canned fish into a big power bowl for some easy comfort food for dinner!
I love this twist on the classic tuna salad! Such a fabulous, irresistible sandwich. Time to stock up on tuna!!
We love tuna here and this looks like a sandwich we could all share and enjoy. Looks so good!
I am all about a good tuna fish sandwich! I’m adding eggs next time.
Sadly, I’m not a big canned tuna fan. However, I think it could grow on me when it’s mixed with basil pesto. It’s a pretty sandwich and I love the hard boiled eggs you’ve garnished with!
I love that you garnished this with hard boiled eggs!
Hey girl – what an awesome baguette sandwich. I’m really digging this with the basil pesto. Great twist on a classic!
I have never seen that tuna before, but it sounds awesome! And ohmahgaw – that is a killer sandwich (makes me want to have a picnic).
I was the same! Now that I am vegetarian I really miss tuna, but this sandwich is something my picky mother would actually eat!
This looks like my kind of sandwich! I recently tried Genova Tuna too and I love it! It really is so much better than tuna packed in water, isn’t it?
