Watergate salad is my favorite retro, no-cook pistachio fluff made with instant pistachio pudding, crushed pineapple, mini marshmallows, nuts and whipped topping. It takes 10 minutes to mix, then chills while you get on with the rest of the meal.
At a glance
The one tip that matters: Don't drain the pineapple. The juice is what dissolves the pudding mix and sets the salad into a soft, scoopable fluff.
Why You'll Love Watergate Salad
- Five ingredients, one bowl and no cooking.
- Make-ahead friendly: it actually tastes better after a night in the fridge.
- A potluck classic for holidays, cookouts and church suppers.
What Is Watergate Salad?
Watergate salad, also called pistachio fluff, pistachio salad or green fluff, is a sweet, creamy no-cook side from the 1970s. It showed up at every church potluck when I was growing up in Ohio. Instant pistachio pudding gives it the pale green color and nutty flavor, crushed pineapple adds tang, and whipped topping and marshmallows make it light and fluffy.
Despite the name it's really a dessert (I serve it as one), and it sits on the same holiday table as our ambrosia fruit salad.

Tips for Success
- Use instant pudding mix. Cook-and-serve pudding needs heat and won't set in this salad.
- Keep the juice. The pineapple juice dissolves and sets the pudding. Draining it gives a dry, gritty salad.
- Fold in the whipped topping gently. Hard stirring knocks out the air and makes the salad dense instead of fluffy.
- Chill it properly. Two hours is the minimum; overnight gives the softest marshmallows and the best set.
- Toast the nuts. Toast the pecans in a dry skillet for 3 to 4 minutes and cool them before adding. They stay crunchier and taste nuttier.

minutesClassic Watergate salad, also called pistachio fluff: instant pistachio pudding mix stirred into crushed pineapple with its juice, then folded with whipped topping, mini marshmallows and chopped pecans and chilled until set. 10 minutes of prep and no cooking.
Ingredients
1 can crushed pineapple in juice, undrained (20 oz can)
1 box instant pistachio pudding mix (3.4 oz box)
1 tub frozen whipped topping, thawed (8 oz tub)
2 cups mini marshmallows
1/2 cup pecans or walnuts, chopped, plus extra to garnish
8 maraschino cherries, to garnish (optional)
Directions
- Pour the crushed pineapple and all of its juice into a large bowl. Sprinkle in the dry pistachio pudding mix and stir for about 1 minute, until no dry powder remains and the mixture starts to thicken.
- Stir in the mini marshmallows and chopped nuts.
- Gently fold in the thawed whipped topping until the salad is evenly pale green. Fold, don’t stir hard, so it stays light and fluffy.
- Cover and refrigerate for at least 2 hours, or overnight, so the pudding sets and the marshmallows soften.
- Stir gently, then top with extra chopped nuts and maraschino cherries, if using. Serve cold.

Variations
- Cranberry Watergate salad: fold in 1/2 cup of dried cranberries with the marshmallows and top with a few more for a red-and-green holiday version.
- Cottage cheese: fold in 1 cup of small-curd cottage cheese for a tangier, higher-protein salad.
- Cherry: stir in 1/2 cup of chopped, well-drained maraschino cherries.
- Coconut: add 1/2 cup of sweetened shredded coconut.
- Lighter: use sugar-free instant pistachio pudding and light whipped topping, and cut the marshmallows to 1 cup.
- Homemade whipped cream: whip 1 1/2 cups of heavy cream with 3 tablespoons of powdered sugar to stiff peaks. Serve it within a day, since it softens faster than whipped topping.
Make-Ahead and Storage
- Make ahead: mix it up to 1 day before serving, cover and refrigerate. Add the garnish just before serving.
- Fridge: keep it covered for up to 3 days. The nuts slowly soften, so add extra on top when you serve it.
- On the buffet: keep it cold and put it back in the fridge within 2 hours, or set the bowl in a larger bowl of ice.
- Freezer: freeze it for up to 1 month. Thaw it overnight in the fridge and stir gently; the texture will be softer.
