Italian Potato Salad With Green Beans & Red  Onions Recipe

Italian potato salad, with green beans and red onion, a super fresh and delicious salad, perfect as a side dish but also as a main course for a lunch.

Since the recipe requires only the cooking of simple boiled potatoes and green beans, it is a candidate to be one of the most popular dishes of the summer.

Not to mention the not insignificant advantage of being able to cook them in advance during the less hotter hours of the day, and let them rest for them to get the best flavor.

This potato salad takes inspiration from a Sicilian recipe, which we Sicilians call “insalata vastasa”.

The term “vastasa”- which in dialect means “rude and vulgar person”- probably refers to the exaggerated and disproportionate use of ingredients.

Traditionally, the preparation of the dish includes potatoes, green beans, tomatoes or cherry tomatoes, red onion, white and black olives, oregano, salt and pepper, and, of course, plenty of extra virgin olive oil. 

But in my version I prepare it without the tomatoes and olives.

Ingredients Needed For This Italian Potato Salad

These are the main ingredients you need for this potato salad recipe.

For the step-by-step directions and measurements, scroll down to our printable recipe card.

Green beans: You can use fresh ones, but frozen ones are fine too.

Potatoes: Yellow-fleshed potatoes are best; they are firm, low in flour and resist cooking better.

Red potatoes can also do well, which have a flesh inside is which is pale, firm and compact, and remains firm even after long cooking.

Other types of potatoes that go well with this recipe:

  • Yukon Gold
  • Fingerling Potatoes
  • Small Boiler Potatoes

Red onion: Gives a unique flavor to our salad.

If you do not like raw onions, you can opt for this little trick so as to eliminate much of their intense flavor and help digestion.

Simply slice them and soak them in water and vinegar for about 1 to 2 hours, then drain the slices, blot them with paper towels and add them to the salad.

Origano: Makes the salad super flavorful.

Salt and pepper.

Oil and balsamic vinegar: To dress this salad, we use oil and balsamic vinegar, the classic Italian dressing.

How To Make Italian Potato and Green Beans Salad

Prepare the onion: First clean the onion and slice it.

Place it in a bowl with very cold water for at least half an hour.

This will make the onion more digestible and cause the pungent elements it contains to run off into the liquid.

Cook the potato and green beans: Put the potatoes in a pot with water and cook them with a lid.

From boiling, cook for about 25/30 minutes.

Then peel and dice them and let cool.

Cut of the ends of the green beans and cook them in salted water for about 10 minutes. Then drain them and keep them aside.

Assemble the salad: In a large bowl put in the potatoes, the green beans and the onion.

Season the salad with salt and pepper, and add the dressing of oil, oregano and balsamic vinegar.

Mix well and refrigerate.

How to Cook Potatoes For The Best Potato Salad

how to cook potato

Pot: Choose new, even-skinned potatoes, wash them under running water, and if necessary use a brush to remove soil.

Then place the potatoes inside a pot with cold water covering them completely and add a tablespoon of salt (for every kg of potatoes), then bring them to the fire.

When the water boils, lower the heat and finish cooking, checking from time to time the desired degree of cooking, skewering the potatoes with a skewer

Microwave: It is also possible to boil potatoes in the microwave, the rule of washing them carefully is the same, then without removing the skin, then we will operate the cooking at 750w, 6 to 12 minutes, depending on the size of the potatoes.

Halfway through cooking, turn the potatoes over and continue cooking on the opposite side.

Pressure cooker: Alternatively, we can boil the potatoes in the pressure cooker, with only 3 cups of water, close the special lid and bring to the stove, calculating about 15 minutes of cooking time.

Recipe variations:

  • Add the tomato and olives: You will make this salad even tastier.
  • Make this salad a unique dish by adding chicken or tuna or even hard-boiled egg and serve it with this delicious focaccia.

How to serve:

This salad for my taste is best served cold; I always make it in the morning for lunch and dinner.

Letting it sit for a few hours in the refrigerator helps and let the flavors blend together.

Frequently Asked Questions

Should The Potatoes Be Peeled?

I, as per the family recipe, make this salad with peeled potatoes, but if you prefer with the peel, that’s perfectly fine too. 

When cooking I always leave the peel on.

You have to consider that the peel is like a protection for the potatoes, which in this case prevents the potatoes from absorbing too much water and thus prevents them from flaking after cooking.

Should Italian Potato Salad Be Served Hot Or Cold?

My advice is to serve it cold, letting it sit for at least an hour in the refrigerator makes the flavors blend together better

Can I make Italian Green Bean Potato Salad ahead of time?

Yes 100%, even better.

You can also prepare it the night before. 

How to store leftovers:

 It will keep in the refrigerator for 2 days in an airtight container.

I do not recommend freezing
