Why I Love Pistachio Salad
When I was a kid I always looked forward to my aunt’s visits, and my aunt’s Pistachio Fluff Salad.
My aunt was famous for her Pistachio Salad because it was always one of the first things to disappear at family gatherings. Imagine my surprise when I discovered that it wasn’t my aunt’s creation but really it was a classic potluck side dish from the 70s.
This Pistachio Salad is:
- A classic recipe and a beloved family favorite.
- So easy to make – it only takes 10 minutes!
- Made with 5 super simple ingredients.
- A sweet treat but we get to call it a salad!
Ingredients
There are only 5 ingredients in pistachio salad. Here are the ingredients you need:

- Cool Whip (or Tru Whip) – I am partial to Tru Whip because it’s a little better for you and doesn’t contain corn syrup.
- Mini Marshmallows – these are a must in this Pistachio Fluff recipe! Or Cranberry Fluff salad. Or Sweet Potato Casserole. Or Rocky Road Cookies. I could go on and on because who doesn’t love marshmallows?
- Crushed Pineapple – this adds a tartness to contrast all the sweet and a little bit of texture, too. No need to drain the liquid, because it all soaks up when you dump it all in and combine it with the pistachio pudding mix.
- Instant Pistachio Pudding Mix – One of the most often asked questions is whether you need to mix this with milk first. The answer is – Nope! To make pistachio fluff, just sprinkle the dry mix in with the other ingredients and it will magically become a creamy, dreamy delight!
- Chopped Walnuts or Pecans – Depending on who I’m making pistachio salad for, I may opt to leave these out and you can too. I love the texture they add however, so I recommend using them.

FAQs
Pistachio pudding is a green pudding that’s made from pistachio nuts. It occasionally contains almond pieces. The instant pudding mix used in this recipe does contain nuts, so please be aware of that if you have an allergy.
You can serve this as a dessert, or as a side dish like they did in the 70s. Who doesn’t want to eat marshmallows with dinner? It pairs great with my Pineapple Glazed Ham!
Pistachio Fluff Salad is known by many names, like “Watergate Salad,” “Pistachio Delight,” or even “Green Stuff.” The original recipe came from General Foods (now known as Kraft), created around the time of the Watergate scandal, hence the name.
It doesn’t matter to me where the recipe originated, I just know this creamy fruit salad is delicious. This is one of those classic midwestern recipes that you always find at church and family potlucks.
A salad is any combination of cold dishes consisting of foods, such as meat, seafood, eggs, pasta, or fruit, prepared singly or combined, usually cut up, mixed with a dressing, and served cold. So while this may truly be a “dessert salad” this green fluff still qualifies as a salad.
How To Store
To store the salad, keep it in an airtight container in the refrigerator. It should be consumed within 3-4 days for best taste and texture. To prevent the salad from becoming watery or soggy, it is best to wait to add the whipped cream until just before serving.

Recipe Notes and Tips
- Use Crushed Pineapple, not chunk pineapple or pineapple tidbits. And don’t drain it. You need the pineapple juice for mixing with the pudding mix.
- Mix Gently: The directions are super simple and literally are just to mix the ingredients together, chill and serve. When mixing, do so gently and sort of fold the ingredients together.
- Variations and Additions: I like to add some maraschino cherries to mine sometimes, and a few drops of green food coloring but those two items are completely optional.
- Don’t Skip the Chilling: You definitely want to chill the salad for a couple of hours to let everything set and get all the flavors to combine and play nicely together.
- Don’t Forget the Garnish: Save a handful of chopped walnuts, chopped pecans, or marshmallows for garnishing the top.
