This homemade slow cooker pineapple jam is a simple way to turn fresh pineapple into a sweet, golden spread with plenty of tropical flavor. The slow cooker does most of the work, slowly cooking the pineapple until it becomes soft, thick, and jammy.
It’s delicious on toast, biscuits, pancakes, waffles, English muffins, or even stirred into yogurt. You can also use it as a filling for cakes, cookies, pastries, and other desserts.
The best part is that you don’t need to stand over the stove the entire time. Once the pineapple and sugar are combined, the slow cooker gently cooks the mixture while the fruit breaks down and the liquid reduces.
Ingredients
- 4 cups fresh pineapple, peeled, cored, and chopped into small pieces
- 2 cups granulated sugar
- 2 tablespoons fresh lemon juice
- 1 tablespoon lemon zest
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
Optional
- 1 tablespoon cornstarch, if you want a thicker jam
- 1 tablespoon water, if using the cornstarch
How to Make Slow Cooker Pineapple Jam
1. Prepare the Pineapple
Start by peeling and coring the fresh pineapple. Cut it into small pieces so it cooks down more easily.
You can chop the pineapple very finely if you prefer a smoother jam. For a more rustic texture, leave some of the pieces slightly larger.
Fresh pineapple works especially well for this recipe because it gives the jam a bright, naturally sweet flavor.
2. Add Everything to the Slow Cooker
Place the chopped pineapple into the bowl of a slow cooker.
Add the granulated sugar, lemon juice, lemon zest, and salt. Stir everything together until the pineapple is evenly coated with the sugar.
Let the mixture sit for about 10 minutes. The sugar will begin drawing some of the natural juices out of the pineapple.
3. Begin Cooking
Cover the slow cooker and cook on LOW for about 3 to 4 hours.
The exact cooking time can vary depending on your slow cooker and how much liquid is released by the pineapple.
After about 2 hours, give the mixture a good stir. You should notice that the pineapple is becoming softer and the mixture is becoming more liquid.
Continue cooking until the pineapple is very tender and the mixture has started to thicken.
4. Break Down the Pineapple
Once the pineapple is soft, you can mash it with a potato masher directly in the slow cooker.
For a smoother jam, use an immersion blender and blend carefully until you reach your preferred consistency.
You don’t have to make it completely smooth. Leaving a few small pieces of pineapple throughout the jam gives it a homemade texture.
5. Continue Cooking Uncovered
Remove the lid and continue cooking on LOW for another 30 to 60 minutes, stirring occasionally.
Cooking uncovered allows some of the extra moisture to evaporate. This is an important step because the jam needs to reduce and become thick enough to spread.
Keep an eye on it during this stage and stir occasionally to prevent the bottom from sticking.
6. Check the Consistency
To test the consistency, place a small spoonful of jam on a chilled plate and let it cool for a minute.
If it stays fairly thick and doesn’t immediately run across the plate, it’s ready.
Remember that the jam will become thicker as it cools, so don’t wait for it to become extremely thick while it’s still hot.
If your jam is still quite thin after the recommended cooking time, continue cooking uncovered in short intervals until it reaches the consistency you like.
7. Add Vanilla
Once the jam has reached the desired consistency, turn off the slow cooker.
Stir in the vanilla extract and give everything one final mix.
Taste carefully and adjust the flavor if needed. If you prefer a slightly brighter flavor, you can add a small splash of additional lemon juice.
8. Cool the Jam
Allow the pineapple jam to cool for several minutes before transferring it to clean jars or containers.
As it cools, it will continue to thicken.
Spoon the jam into clean containers, leaving a little space at the top. Allow it to cool completely before covering and refrigerating.
How to Store Pineapple Jam
For a simple homemade version like this, the safest option is to store the finished jam in the refrigerator.
Keep it in clean, covered containers and use it within about 2 to 3 weeks, provided it has been continuously refrigerated and handled with clean utensils.
You can also freeze the jam for longer storage. Divide it into freezer-safe containers, leaving some room for expansion, and freeze for up to several months. Thaw it in the refrigerator before using.
Important Note About Canning
Although pineapple jam is commonly preserved, this recipe should not automatically be treated as a shelf-stable canning recipe. Simply putting hot jam into jars and sealing them does not make a recipe safe for room-temperature storage.
If you want to keep this jam in a pantry rather than the refrigerator or freezer, use a properly tested pineapple jam or pineapple preserve recipe from a reliable home-canning source and follow its processing instructions exactly.
Ways to Use Pineapple Jam
There are so many ways to enjoy this homemade jam.
Spread it over warm toast with butter for an easy breakfast. Spoon some over pancakes or waffles instead of syrup, or swirl it into plain Greek yogurt for a quick snack.
It also makes a wonderful filling for baked goods. Try spreading a thin layer between cake layers, adding it to thumbprint cookies, or using it inside homemade pastries.
For something simple, serve it alongside biscuits or English muffins.
You can even use a little pineapple jam as a glaze for baked ham or roasted meats. The sweet and tangy pineapple flavor pairs especially well with savory dishes.
Tips for the Best Pineapple Jam
Use ripe pineapple: A ripe, flavorful pineapple will give you a much better-tasting jam.
Cut the fruit evenly: Smaller pieces soften faster and make it easier to achieve a consistent texture.
Don’t rush the reduction: The jam needs time for excess moisture to evaporate. Cooking it uncovered near the end helps concentrate the flavor.
Stir occasionally: Especially during the final stage, occasional stirring helps prevent sticking.
Adjust the texture: Mash the pineapple for a chunky spread or blend it for a smoother consistency.
Let it cool: Hot jam will look thinner than cooled jam. Give it time to set before deciding that it needs additional cooking.
Frequently Asked Questions
Can I use canned pineapple?
Yes. Canned pineapple can be used, although fresh pineapple usually provides a brighter flavor. If using canned pineapple, drain it very well before adding it to the slow cooker.
Can I make this less sweet?
You can reduce the sugar, but remember that sugar affects both the flavor and texture of jam. Reducing it too much can result in a thinner, less jam-like consistency.
Can I make the jam completely smooth?
Absolutely. Once the pineapple has softened, an immersion blender can be used to create a smoother spread. Blend until you reach the texture you prefer.
Why is my pineapple jam still runny?
It may simply need more time to reduce. Remove the slow cooker’s lid and continue cooking on LOW, stirring occasionally. Keep in mind that the jam will thicken further as it cools.
