Kitchen Essentials
Ingredients
- 16 Cups Zucchini Peeled and diced into bite size pieces (about ½-inch cubes)
- 1 ½ Cups Sugar
- 1 ½ Cups Lemon Juice
- 46 Ounces Pineapple Juice 1 large can
Instructions
- Prepare the zucchini. Peel your zucchini and cut it into ½-inch cubes. If you have large zucchini with big seeds, scoop them out for the best texture.16 Cups Zucchini
- In a large pot or Dutch oven, combine the zucchini, sugar, lemon juice, and pineapple juice. Bring the mixture to a boil over medium-high heat, then reduce to medium heat and simmer for 20 minutes. Stirring occasionally.1 ½ Cups Sugar, 1 ½ Cups Lemon Juice, 46 Ounces Pineapple Juice
- Sterilize Jars. If this is your first time canning, see the notes section for more directions. This recipe makes 8-9 pints.
- Fill jars. Carefully ladle the hot mixture into sterilized jars, leaving ½-inch headspace. De-bubble by gently tapping the jars or running a non-metal knife along the inside edges. Add more hot mixture if needed.
- Seal and wipe jars. Wipe the jar rims with a wet paper towel to remove any residue. I like to use paper towel dipped in a bit of vinegar. Place the lids and rings on. The rings should just be barely tight.
- Process jars. Using a boiling-water canner, process pint jars for 20 minutes. Important: Don’t start timing until the water is at a rolling boil.
- Remove jars carefully and let them sit on a towel on your counter for 24 hours. After that, check the seals. Properly sealed jars will have a concave lid that doesn’t move when pressed.
- Label and store. Wipe jars clean, label them with the date, and store in a cool, dark place. Your zucchini pineapple cans will keep for up to a year if stored properly.

How to Sterilize Jars and Lids
Properly sterilizing jars and lids ensure your zucchini pineapple preserves are safe and will last. Here’s a simple method for beginners:- Wash thoroughly
Wash jars, lids, and rings in hot, soapy water. Rinse well to remove any soap residue. - Sterilize jars
- Place jars in a large pot or boiling-water canner.
- Fill the pot with enough water to cover the jars completely.
- Bring the water to a boil and let the jars boil for at least 10 minutes.
- Keep the jars in hot water until you’re ready to fill them. This prevents thermal shock when adding your hot zucchini mixture.
- Sterilize lids
- Lids should not be boiled for a long time, as this can damage the sealing compound.
- Place lids in a small saucepan of hot, but not boiling, water for 2–3 minutes.
- Work with hot jars
- Using tongs or jar lifters, carefully remove hot jars from the water, allowing excess water to drip off.
- Fill jars immediately with your hot zucchini pineapple mixture to maintain safety and prevent contamination.
Tips for Success
- Oversized Zucchini. For this type of recipe I prefer to use the oversized zucchinis. It usually takes about 3 large ones.
- Peeling and cutting zucchini. Peel your zucchini and cut it into uniform ½-inch cubes. Consistent sizing ensures an even texture and helps the zucchini absorb the pineapple flavor.
- Remove large seeds. If your zucchini has large seeds, scoop them out for a better finished product.
- De-bubbling jars. After filling jars, run a knife or small spatula along the inside edges to release any trapped air bubbles. This prevents gaps and ensures a proper seal.
- Wipe jar rims carefully. Even a small drop of liquid on the jar rims can prevent a seal. Wipe with a clean, damp paper towel before adding lids and rings.
- Headspace matters. Leave ½-inch headspace in each jar. This allows for expansion during processing and helps create a vacuum seal.
- Use a rolling boil. Only start the boiling-water canner timer once the water is at a rolling boil. This ensures safe home food preservation.
- Check your finished product. After jars have cooled for 24 hours, press the lid centers. A proper seal will not flex up and down.

Recipe Variations
- Half-pint jars. Perfect for smaller batches or gifting, especially if your harvest yields a lot of zucchini.
- Combine pineapple juice with apple juice. For a slightly more tropical flavor.
- Zucchini tidbits in juice. Treat your finished product like canned pineapple tidbits. Great for desserts, salads, or savory dishes.
Storage
- Shelf life. Store sealed jars in a cool, dark place. Your zucchini pineapple cans should keep for up to 12 months if stored properly.
- After opening. Once opened, refrigerate and use within 1–2 weeks. Treat it like you would canned pineapple or other high-acid canned fruits.
- Label jars. Always mark your jars with the date of canning for easy reference.
