Italian Potato Salad with Authentic Pesto Recipe

Authentic Pesto Recipe with Homemade Italian Potato Salad from Spinach Tiger

Italian Potato Salad is a dish that showed up at every picnic and summer holiday when I was growing up. It’s not complicated. It’s not dangerous in the heat. It’s tasty and almost everyone loves it. Back then, my family didn’t make pesto. They simply used olive oil, oregano, vinegar, salt and pepper. That’s not a bad dish, but this is just a little more special.

This will take the place of that mushy potato salad that curdles and worries us at outdoor gatherings.

I made Italian Potato Salad with Pesto for our Easter picnic at the farm, with no worries about spoiling or mayonnaise. We took the leftovers home and we ate on those potatoes for the next few days. They can be fried for omelettes, frittatas etc. They can be heated and served warm.

Italian Potato Salad with Authentic Pesto Recipe is a Pot Luck Party Recipe

This is the dish that is okay to sit out for a long time. It’s served at room temperature, and I guarantee will go fast!

The beauty of this dish is that you do not need to peel the potatoes. It’s a simple dish that adds a lot of bulk, color, texture to a table with very little effort.

Pesto is so easy to make. The store bought pestos don’t have the same fresh taste and are too often too garlicky and not in a good way. Pine nuts are expensive, so I don’t use them as much, but I do miss them.  Walnuts are a great substitute, and you don’t need too many of them.

Truthfully, in this recipe, you can skip the nuts if you want. Flavor is what you’re looking for and the Pecorino Romano will do its job. I go back and forth about what cheese to use for pesto. Pecorino Romano or Parmigiana Reggiano?

As long as you have an authentic cheese from Italy, use either or a combination. We prefer to use both, but lean towards the pecorino if just using one. It’s the saltiness we love so much. (Costco sells both Pecorino and Parmigiano Romano in nice big pieces at a reasonable price. Never buy pre-grated cheese. There are too many reasons to go into, but the flavor, quality and quantity will be diminished.

Marcella Hazan changed my outlook about pesto when she taught me two things from her legendary book, The Essentials of Classical Italian Cooking.  (affiliate)

She adds  butter at the end, which  makes the pesto creamy, and she mixes the cheese in by hand, even if using a food processor. Those two rules for an authentic  pesto have stayed with me for years.

Also, it’s important to reserve some starchy water (it can be pasta water or potato water) to add into the pesto, so its not so oil heavy.

This is a room temperature Italian potato salad.

The biggest mistake you could make would be to refrigerate the potatoes, because that will change their texture and pesto is not good cold.  Make these the day of your event and leave them out. Once the day is over and you must refrigerate, then I recommend eating them heated. You can even heat and cool off a little.

I like to serve this with a side of green beans made the same way, as they just go together so well. If it’s tomato season, add some fresh tomatoes for an Italian trio.
