Tuna Pasta Salad

Tuna pasta salad loaded with creamy avocado, red onion, and diced tomatoes. This is a summer staple! 

We had our first pool day of the season yesterday and you guys, it was a.maz.ing.

I mean, yes. The water was still pretty cold at just 78 degrees, but it was worth it!!

I have been missing the sunshine and the warmth and the smell of suntan lotion.

Then we sat outside all evening around a fire with some margaritas, because SUMMER!

Cold pasta salad with tuna! This is the perfect side dish recipe or quick lunch all summer long! #recipe #summer #tuna #pastasalad

It was lovely until all the mosquitoes in town showed up. Why do bugs have to be a thing? Ugh.

Anyway, this time of year is what is affectionately known as pasta salad season in my home.

Sorry not sorry, but we’ll be eating this cold tuna pasta salad for lunch and as a side at every barbecue from now until forever. It’s the right thing to do.

I shared my Italian pasta salad with you guys last month and it was a huge hit. It’s packed full of pepperoni, salami, pepperoncini, and red onion. So good!

I also make this BLT pasta salad all summer long and it’s a winner too!

This tuna pasta salad recipe is going to be a hit too, I think. Especially if you like avocado in your pasta salad and really, how could not?

(Please don’t tell me if you don’t like avocados, because I just don’t speak that language.)

How to make pasta salad with tuna:

You’ll want to start with cooked pasta. Any small shape that you love will work well here.

I’ve used a mix of campanelle and farfalle this time around, because I had a couple open boxes. Macaroni and rotini are great choices too.

I like to rinse my cooked pasta under cold water to quickly cool it down.

You’ll dice up an avocado, some cherry tomatoes, red onion, and chives to add to cooked pasta along with some tuna.

Mix together the mayonnaise, dill, lemon juice, salt and pepper and add that to the bowl with the pasta, tuna, and veggies.

Toss gently to coat everything in the dressing mixture.

I prefer to let this cold tuna pasta salad chill out in the fridge for an hour or two before eating. It helps the flavors meld together and I like my pasta salad very cold.

Be sure to cover the dish tightly.

If you plan on making this more than an hour ahead, don’t add in the avocado until just before serving, otherwise it will turn brown.

This tuna pasta salad recipe is so easy and it’s got great flavor.

What to serve with cold tuna pasta salad: 

This makes a great lunch – double the tuna if you’d like it to be extra filling.

These are the best turkey burgers! So juicy and perfect on the grill!

If you’d like to serve this as a side, it will work well with any of your standard barbecue fare – turkey burgers, grilled buttermilk chicken, or hot dogs and brats.

My Jiffy corn casserole, baked beans recipe, and broccoli cheese casserole all go well alongside this pasta salad.

For dessert, try my easy peach cobbler.

Hope you guys love this cold tuna pasta salad as much as we did!
