Steam Canning is a fantastic substitute for the water bath. (Not to be mistaken for pressure canning, it is different.)  I’m leaning more and more on my steam canner!  It is super easy and uses less water.  Learn how to do Steam Canning.

Why this recipe when you’ve got too much zucchini? 

Everyone who has ever had a bumper crop of zucchini knows about the zucchini scramble.

  • You are scrambling to offer zucchini to co-workers or friends and even 
  • You might just be caught sneaking zucchini onto neighbors porches or co workers parked cars. 
  • You will almost certainly be searching for zucchini recipes of all sorts.  Sometimes these recipes are delicious but they often don’t really use up a lot of this abundance. 
  • You’ve got a freezer full of zucchini. 
  • Possibly you’ve dehydrated zucchini as well.  
  • You might even have jars of Zucchini Relish to replace your traditional pickle relish.   

Canning Zucchini in Pineapple juice is a great way to use up this excess as it really does use a good amount of zucchini.  And this recipe is sweet!  And unexpected! Faux pineapple?!?  Sounds good to me.  

Extended Directions On How To Make Zucchini Pineapple

Choosing Zucchini for Faux Pineapple

Any ripe zucchini can be used for faux pineapple.   I like to use the overgrown variety that is not especially useful for dipping and frying.  

How to Prepare Zucchini for Faux Pineapple

To prepare it simply peel, cut in half length wise, and scrape out the large seeds if needed.

Then you want to chop or shred into the size pieces you want.  This should be no bigger than about 1/2 inch cubes.  This can be done by hand but I found my food chopper to be pretty quick.  The results are elongated but small enough to be appropriate.

I tried a large shred blade and that worked nicely. You would not want your pieces much smaller than what you see in the picture below. A finer shred would not work very well.

Coarsely shredded zucchini.

But then I decided to try my French fry blade and see what happens. That is my favorite!  It is a little chunkier, but still nice small pieces. 

French fry cut zucchini.


For one batch of about 8 or 9 pints you want 

  • 4 quarts chopped or shredded zucchini. 
  • 1- 46 oz can of purchased unsweetened pineapple juice.  (It is plenty sweet!) 
  • 1 1/2 cups lemon juice.  Use the bottled kind, not home squeezed.  
  • And 3 cups sugar.  (I can’t find anywhere that it is ok to reduce the sugar, so yes, you’ll need the whole 3 cups.) This is not a health food.  But it is so very good!

Canning Pineapple Zucchini

This is a hot pack canning recipe which means you heat your ingredients before they go in the jar.  Mix the pineapple juice, lemon juice and sugar in a large pot. Add the chopped or shredded zucchini to the juice mixture. Bring to a boil reduce the heat and simmer for 20 minutes.  Stir occasionally.

Fill your jars with the zucchini and sweet syrup.  

Leave a 1/2 inch headspace.  This is the space between the level of the food and the lid of the jar.  Having the proper amount is important for expansion during processing but not too much so you end up with too much air space.  

I find it easiest to use a slotted spoon to scoop in the zucchini and then use a ladle to top it off with liquid.  Try to have all your zucchini covered with the pineapple liquid.  

Use a bubble tool to remove any air pockets.  Simply run it down the sides of the jars moving things around a bit.  Be gentle, any bubbles will automatically rise. 

Then wipe the rim with a damp paper towel or lint free cloth.  If you leave the rim sticky with juice it may interfere with the seal.  

Add your flat lid and screw bands.  Tighten just finger tight.

Frequently Asked Questions

Can this be stored in the refrigerator?

Yes, This could also be stored in your refrigerator. It would last just as any other canned fruit would. I’d say a week or so. You don’t have to can this mock pineapple zucchini for storage on the shelf but be sure you’ll use it up as it won’t store as long in the refrigerator.

I would suggest you cut the recipe in half to make less if you just want some on hand for a specific dessert recipe.

Can I put this in the freezer?

Sure, the faux pineapple will store well in the freezer as well. I’d put it in freezer containers and measure out how much is in each. For example, freeze in 1 cup quantities. That way you know how much you’ll need for specific recipes.

The easiest way to do this would be to divide up the solids (the zucchini) into freezer containers, then add juices evenly to each. This way you don’t end up with all zucchini in some bags and a lot of left over juice.

Doesn’t zucchini have to be pressure canned?

Good question! Squash is considered a low acid food and usually does need to be pressure canned. But… that is only for winter squash like pumpkin. Summer squash actually can only be canned as a pickle… or as this zucchini pineapple. There are no plain summer squash canning suggestions.

The timing of this is so weird. I was just discussing this with my aunt yesterday. My mom has canned this for almost 50 yrs. It is surprisingly good. This is the same recipe my mom used
