Ingredients
- Instant pistachio pudding mix: gives the signature color and flavor pick a real pistachio blend for best taste
- Crushed pineapple: adds sweetness tang and juiciness undrained for extra moisture choose one with no added sugar for a cleaner flavor
- Mini marshmallows: create that fluffy chewy bite grab fresh and soft ones so they do not get sticky
- Chopped pecans or walnuts: bring a nutty crunch optional but so good toast the nuts if you want more depth
- Canned mandarin oranges: add a citrusy burst totally up to you use fruit packed in juice not syrup for balance
- Whipped topping: the creamy cloud that holds it together thaw it fully before folding in and choose a non-dairy or light version if preferred
- Garnishes: like extra nuts or maraschino cherries give a festive finish fun for serving on holidays
Instructions
- Combine Pineapple and Pudding
- In a large mixing bowl add the entire can of crushed pineapple with juice and sprinkle in the instant pistachio pudding mix Stir together slowly to make sure the pudding dissolves fully and the mixture turns a light green This forms the flavor base so take a moment to get it smooth and even
- Fold in Whipped Topping
- Gently spoon in the thawed whipped topping and use big sweeping motions to fold it into the pudding pineapple blend The idea is to keep everything airy so go slowly until no streaks remain
- Add Marshmallows Nuts and Oranges
- Sprinkle in mini marshmallows and chopped pecans or walnuts if you are using them If you like a touch of citrus pop in some mandarin oranges Gently fold these in so everything stays fluffy and not mashed
- Chill
- Cover the bowl tightly with plastic wrap or a lid Place in the fridge for at least one hour This step allows all the flavors to blend and the texture to set into that classic fluff
- Garnish and Serve
- Once chilled give the salad a gentle stir right before serving Top with extra nuts or a few maraschino cherries if you want a retro look Serve it cold for the best texture and flavor

I always use extra pineapple because it highlights that sweet tropical note and reminds me of the first time I made it for my mom She would always go back for seconds

This salad is best stored covered in the refrigerator for up to two days The whipped topping keeps it creamy but after that the texture can get watery If you want to make it ahead prep all the ingredients the day before keep them separate then stir together just before serving for the best consistency Serve straight from the fridge for the fluffiest results
Ingredient Substitutions
Feel free to swap walnuts for pecans or leave nuts out entirely for allergies If you want extra richness stir in some coconut flakes or fresh whipped cream Sugar free pudding and light whipped topping work great for a lower sugar version If you do not have mandarin oranges more pineapple or even a handful of grapes add extra fruity flair
