Easy Crock-Pot Banana Jam recipe using those old and mushy bananas. 3 Ingredients and made in the slow cooker. Serve on toast or English muffins!

Slow Cooker Banana Jam
This is a great way to use up those old and not so pleasant looking bananas. When cooking this, keep an eye on it. You want it at the point that it bubbles up and almost doubles it size. At that point, stir and turn off. The first time I did this , I was not paying attention and let it go past this point (almost 2 hours cooking) and my jam burnt. You do not want it a brown color. The jam will still retain a yellow color even if you are using those old black and mushy bananas.
This made about 2 half pints, with a little bit extra which my kiddo and I ate before we even took photos of the jam.
It is THAT good.

Frequently Asked Questions
I like to use bananas that are lightly spotted with brown spots on the skin. I find that bananas at this ripeness level are sweet without being too sweet. Once the banana skins turn completely brown I find that the banana inside is super sweet, too mushy and starts to give off a fermented flavor.
Once you have made the banana jam in your slow cooker you can store the jam in food safe containers for up to 2 weeks in the refrigerator or 1 year in the freezer.
Using a the water bath canning method you can process this banana jam in clean canning jars for up to 1 year. You will want to process the jars of jam for 10 minutes if you are at or below sea level. Adjusting accordingly if you are at higher altitudes using this guide: Adjusting for High-Altitude Canning

Can you also complete the canning process with a hot water bath or would it turn the fruit brown?
Just made homemade banana jam
Awesome Mary!
Does this recipe shelf life or should it be refrigerated?
Hi Heather, this recipe should be stored in the refrigerator, freezer or canned in canning jars using a water bath canner. If you can the banana jam in jars it is shelf stable but for best flavor should be eaten within about 6 months.
Was wondering about doubling the recipe , and could you puree the bananas in a blender or food processor instead of mashing them ??
Thanks, it sounds delicious, can’t wait to try it. !!!
You can puree the bananas for sure and while we have not tested this recipe doubled I think it should work. If you try it be sure to come on back and let us all know how it turned out for you!
Hello! I’m wondering if I can use some of the 80,000 saved bananas I have in the FREEZER? If I defrosted them first?
Thank you!
This recipe has not been tested using frozen and then thawed bananas, but you could certainly try! Hope you enjoy!
