Sweet, tangy, and perfectly spiced, this Banana Ketchup will have you rethinking your condiment habits from here on out.

I regularly get questions about how to preserve bananas. In the past, my default answer was to guide people away from trying it. The reason? Bananas are low in acid and there’s long been a dearth of reliable, scientifically tested recipes employing them. However, things are changing. The makers of Ball® home canning products have recently added this canning safe recipe for banana ketchup to their library of preserves.

Ingredients for banana ketchup on a metal sheet pan - ginger, garlic, lemon juice, apple cider vinegar, water, onion, tomato paste, sugar, spices, and bananas.

To make this sweet, zippy preserve, you need two cups of mashed banana (I needed four bananas to total this amount), 2 cups of chopped onion, 3 garlic cloves, 2 teaspoons freshly grated ginger, 1-2 birds eye chilis, 1 cup water, 3/4 cup sugar, 2 tablespoons tomato paste, 1 cup apple cider vinegar, 1/2 teaspoon allspice, 1/2 teaspoon turmeric, 1/4 teaspoon cinnamon, and 2 tablespoons bottled lemon juice.

Close up on bananas, spices, and sugar.

You start by simmering the onion and garlic in 1/4 cup of water until they’re soft. While the aromatics cook, prepare a boiling water bath canner and 4 half pint jars. Wash your new lids and rings with warm, soapy water and set them aside so that they’re ready for you when you’re ready for them.

Then you add the rest of the ingredients and cook, stirring regularly, until it has thickened. This should take 15-20 minutes. And just a note here. Make sure to use a silicone spoon or a wooden spoon that you don’t mind dyeing a vibrant shade of yellow. Even though there’s only 1/2 teaspoon of turmeric in this recipe, it’s still potent enough to stain everything it comes into contact with.

Cooked banana ketchup in a pot, before being pureed.

Once the ketchup is done cooking, use an immersion blender to puree it smooth. Use canning tongs to remove a hot jar (I used Ball® Smooth Sided Half Pint Jars) from your prepared canner. Funnel the hot banana ketchup into the jar, leaving 1/2 inch headspace. Remove the air bubbles. Wipe the rim, apply a clean, new lid and a ring and return the jar to the canner. Repeat this process with the remaining jars and ketchup. Process the sauce for 20 minutes, adjusting for altitude if you live above 1,000 feet in elevation.

When the processing time is up, turn off the heat, remove the lid from the pot and let the jars stand in the pot for an additional five minutes (this allows them to cool more gradually, which helps prevent siphoning and should also help develop a more robust seal).

Remove the jars from the canner and set them on a folded kitchen towel. Let them sit undisturbed for 12-24 hours so they can fully cool and seal. Before storing, make sure to check that the seals are firm and unbending. Sealed jars are shelf stable up to 18 months, any unsealed jars should be refrigerated and used promptly.

My finished yield ended up being three half pints and a few spoonfuls that I popped into a 4 ounce jar and put in the fridge. This ketchup is delicious anywhere that you’d use the traditional tomato version. So far, I’ve enjoyed mine with roasted sweet potato wedges and spread onto a black bean burger.

  • Can you please post the actual recipe from Ball with an official statement from them saying this is a safe and tested recipe? If not, then this should be considered not shelf stable, and anyone risking it is foolish.

    1. Frank, this is the official, fully tested recipe from Ball. They haven’t published it on their website yet, but have thoroughly tested it for safety. I will ask them if there’s some additional confirmation that they can provide.

  • A while ago Kraft put out a booklet of recipes “Fruits of the Harvest Beyond the Basics Homemade Jams and Jellies” that has three recipes for Banana Butter. All three are basically the same recipe, each is written specifically for different pectin (Regular Sure-Jell, Low sugar Sure-Jell, and Certo). It uses a fairly high amount of lemon juice and Fruit Fresh and the end result is a jam consistency not really a fruit butter but it’s tasty.

  • Sorry but this is not a validated recipe from Fresh Preserving, here is the reply I received from them:

    Thank you for taking the time to contact Fresh Preserving. We truly appreciate your interest in our products.

    I will be happy to assist you today. I do understand you would like to verify if the Banana Ketchup recipe located on website is a Ball approved recipe. To answer your question no, unfortunately that recipe has not been safety tested by our food scientist at this time. We do not recommend this recipe. I hope this information was useful for you. Stay safe during this time and have a great day.

    If I can be of further assistance, please reply to this email directly so that we can see all previous replies. You may receive a brief survey about your experience with me. Thank you in advance for any feedback you may provide.

    1. Sylvie, I work directly with Ball. This fully tested recipe is scheduled to go up on their website in November. It may be that the customer service people aren’t aware of recipes that are in the pipeline, but I assure you it is safe and approved.

    1. Thanks for the vote of confidence! This really is a tested recipe from Ball, so I feel totally comfortable with the safety of this recipe.

  • I get Fresh Preserving newsletter and the recipe is posted today from them. So it is approved for canning.
    I’m going to try it because it sounds delish….

  • Wonder if a natural sweetener (like stevia) instead of sugar will work for this and does it alter the shelf life (or dropping sugar at all)?

    1. Using a non-sugar sweetener like stevia will alter the flavor, consistency, and shelf life of this ketchup. I wouldn’t recommend it.

  • 12/26/22 I am a retiree and this recipe intrigues me, I will be trying it. Since you work for Ball, and all the acid in the recipe bumps up the safety factor, what @ trying plantains? I would really like to find a canning recipe that uses plantains, due to inflammation, I eat plantains often. This looks like it might work. Bonus if you can work some pineapple into it.

    1. Hi Barbara. I don’t work for Ball. I was doing some sponsored content for them when I wrote this post. I don’t have any insight to offer when it comes to working with plantains.
