Banana ketchup is a Filipino condiment made from mashed saba bananas, vinegar, brown sugar, and spices — sweet, tangy, and just a little hot. It tastes nothing like tomato ketchup, which is exactly the point. Make a batch and you have a versatile burger sauce that keeps in the fridge for three weeks.
What makes this version work
Two things matter most here. First, cook the tomato paste in the oil with the spices for that full 1–2 minutes until it darkens — skipping this step leaves a raw, tinny flavor that no amount of simmering will fix later. Second, blend the mixture completely smooth before tasting and adjusting salt. Chunky banana ketchup reads as undercooked even when it isn’t, and the flavor assessment changes once the texture is right. Everything else in this recipe is forgiving.
Make-ahead notes
This ketchup is genuinely better after 24 hours in the fridge — the vinegar mellows and the spices settle. Stored in a sealed jar or squeeze bottle, it keeps for up to 3 weeks refrigerated. For longer storage, freeze it in ice cube trays, then transfer the frozen cubes to a zip-lock bag; individual portions thaw in about 20 minutes at room temperature and hold well for up to 3 months. Stir or shake after thawing since some separation is normal.
If something goes sideways
- Ketchup tastes flat or bland: Add vinegar a teaspoon at a time, not more sugar. A flat sauce almost always needs acid, not sweetness.
- Texture is gluey or starchy after blending: Thin it with water, one tablespoon at a time, and return it to low heat for 5 minutes. Over-mashed bananas can make the starch seize up during blending.
- Color is pale yellow instead of reddish-brown: This is normal without food coloring — the tomato paste gives a slight orange tint but won’t produce the vivid red of commercial versions. The flavor is unaffected; add a small pinch of paprika if the color matters to you.
- Ketchup is too sweet: A splash more vinegar fixes this faster than adding chili. Taste after each addition and give it 30 seconds to integrate before adding more.
- Mixture scorched on the bottom: Switch to the lowest heat your burner can manage and use a heavy-bottomed pan. If you catch it early, pour — don’t scrape — the unburned portion into a clean pan and continue; scraping pulls the bitter bits in.
Filipino Banana Ketchup
Ingredients
- 2 cups ripe saba bananas peeled and mashed
- ½ cup organic white vinegar for a balanced tang
- 1 cup dark brown sugar adds depth and sweetness
- 2 cups water
- 1 medium onion finely chopped
- 4 cloves garlic minced
- 1 ½ tablespoons tomato paste
- ½ teaspoon chili powder adjust for spiciness
- ¼ teaspoon salt
- ¼ teaspoon ground black pepper
- 2 tablespoons coconut oil or neutral oil like vegetable oil
Instructions
- Heat the coconut oil in a medium saucepan over medium heat. Sauté the onions until translucent and fragrant, about 3-4 minutes.
- Add garlic and continue cooking until golden brown, releasing a rich aroma, about 2 minutes.
- Stir in the tomato paste, chili powder, salt, and pepper. Cook for another 1-2 minutes until the paste darkens slightly, deepening the flavor.
- Add the mashed bananas, vinegar, brown sugar, and water. Bring the mixture to a simmer, stirring occasionally until the ingredients are well combined and the sugar has dissolved completely.
- Reduce the heat to low and let the mixture simmer for about 20 minutes, stirring occasionally until thickened to your desired consistency.
- Allow the mixture to cool slightly. Use an immersion blender or pour the mixture into a blender to puree until smooth. Adjust seasoning if necessary.
- Transfer the ketchup to sterilized jars or squeeze bottles. Store in the refrigerator for up to 3 weeks.

Frequently asked questions
Can I use regular Cavendish bananas instead of saba bananas?
Yes, but the result will be noticeably sweeter and less starchy. Saba bananas are drier and more neutral, which gives the ketchup its body; Cavendish bananas are wetter and sweeter, so reduce the brown sugar by about two tablespoons and expect a slightly thinner sauce.
Do I need to sterilize the jars, or can I just use a clean container?
A thoroughly washed and dried jar or squeeze bottle is fine as long as you’re storing the ketchup in the fridge and using it within 3 weeks. Full sterilization matters for shelf-stable canning at room temperature, which this recipe is not designed for.
How do I know when the ketchup has thickened enough?
Drag a spoon across the bottom of the pan — if the line holds for a second before the sauce flows back, you’re there. Keep in mind it will thicken further as it cools, so pull it off the heat slightly before it looks done.
What burgers does this actually work on?
It works best anywhere you’d use a sweet-heat sauce — grilled beef burgers, crispy fried chicken burgers, and anything with bacon. Skip it on delicate fish burgers where the sweetness will overpower the protein.
