Pistachio is having a moment – finally. Pistachio flavor is probably my favorite – I love eating pistachios but I love pistachio flavored treats even more! This easy pistachio pie recipe is full of delicious flavor – if you’re like me you’re going to love it!r in marshmallows and nuts. The flavor is actually really good!
How to make Pistachio Pudding Pie
- The star of this pie is instant pistachio pudding mix. There are no substitutions for this.
- A can of crushed pineapple is the liquid that helps make the pudding. Can you substitute milk? Yes you can – see the recipe notes.
- Cool Whip is the body of the pie. You could use freshly whipped cream if you prefer, but whipped topping holds up so much better.
- I love adding Mini Marshmallows into the pie filling for fluff and body, and chopped pistachios for even more texture and flavor.
- Want even more flavor? Add 1/8 teaspoon almond extract!
- Traditionally I’ve used a graham cracker crust. You can use my homemade recipe or just buy a store bought one (I won’t judge). You could also make a Nilla Wafer Crust or a shortbread crust. This recipe is written for a 9-inch pie pan.
- I love to decorate the top of the pie with whipped cream or cool whip and sprinkle with nuts, but you could also add maraschino cherries on top.

My grandmother used to make this. Only difference was she used individual graham cracker pie shells. That way everyone had their own and didn’t have to slice it. She would make it for her retired teacher union luncheons. Fabulous recipe!!
Can this pie be frozen?
In theory yes since it has cool whip, but I’m not sure if it will thaw properly.
I love this pie. The one thing I would mention for me anyway I was originally taught by my mother you put the pineapple and the pudding mix together and you beat it with the mixer and chill is thick and then you stir in your Cool whip or nuts or marshmallows if you like. for me personally I just like the pudding the pineapple and the Cool whip there’s enough nuts in the pudding to satisfy my taste for nuts and although I really like miniature marshmallows I like the pie better without them but I do use the graham cracker crust and it is ambrosia thank you so much for posting this recipe .again.
Looks so good, can’t wait to try it. Thanks!
You, being from California, must have a different version. Here in Texas Watergate Salad has the things you mentioned but also mandarin oranges (which I like to chop into small pieces). I’m sure it’s good either way!
