You'll love this pistachio fluff salad!
Watergate salad tastes like a creamy, fruity pistachio mousse with tiny pops of sweetness from the marshmallows and a soft crunch from the nuts. The pineapple adds a subtle tang that balances the sweetness, and the pudding mix brings in that classic pistachio flavor without being overpowering. It’s light, fluffy, and a little quirky in the best way possible!
ADD A BRIEF NOSTALGIC STORY: Grandma Dottie used to bring this pastel green fluff to every Easter brunch and summer picnic. It’s one of those retro dishes that looks like a green pastel blob people turn their nose at, until they actually tasted it. Pistachio anything was my grandpa's favorite flavor, so we had this often!
What You Need to Know

- Chilling is non-negotiable. Let it sit for at least an hour in the fridge so the flavors meld and the texture sets.

Notes
FAQs
What's the History of Watergate salad?
The name came about in the 1970s, possibly as a nod to the Watergate scandal. Kraft introduced the pistachio pudding mix around the same time, and a Chicago food editor gave it the quirky name to match other Watergate-themed recipes.
Can I make it the night before?
Yes. In fact, chilling it for a few hours or overnight helps the flavors meld and the texture set.
What can I use instead of pistachio pudding in Watergate Salad?
If you can’t find pistachio pudding, substitute it with vanilla or instant coconut pudding mix and stir in chopped pistachios for flavor and texture. It won’t be exactly the same, but it will still be delicious and creamy.
Can I use homemade whipped cream instead of Cool Whip?
You can swap Cool Whip with stabilized whipped cream or coconut whipped topping, but it may slightly change the texture and sweetness.
How long does Watergate salad last in the fridge?
Watergate salad stays fresh for 2–3 days when stored in an airtight container in the refrigerator. For the best texture, add garnishes like cherries or extra nuts just before serving to keep them from getting soggy or bleeding into the salad.
