How To Make Watermelon Jam In Instant Pot?
We use the following ingredients to make the watermelon jam in the instant pot.
Ingredients to make watermelon jam without pectin
watermelon fruit 4 cups chopped
sugar 1 cup
lemon juice 4 tablespoons – I used the juice from a medium sized lemon, make sure to remove the seeds
cornstarch 2 tablespoons
vanilla extract 1 teaspoon
Step By Step Process
Add the fresh watermelon pieces to the instant pot.
Also add the sugar and lemon juice to the instant pot. Stir the contents very well so the sugar and lemon juice is mixed with the watermelon pieces well.
If any seeds are inside the fruits, many of those will float to the top once you stir the contents and you may remove them with a spoon as much as you can.
Close the instant pot with lid in sealing position and cook in high pressure for 15 minutes.
Wait for a natural pressure release.
Once the pressure is all released, carefully open the lid.
Stir and mash the contents using a potato masher. Also add the vanilla extract, stir in.
If there are more seeds, many of those will float to the top and you can easily remove many of those with a long spoon.
Simmer the contents (using saute function) while you keep stirring and mashing in between for about 10 to 12 minutes.
Again, any seeds that may float to the surface, can easily be removed using a long spoon throughout the process. A few seeds here and there, are fine!
At this stage, the watermelon pieces will almost look like jelly like in texture but since its watermelon, there will still be little liquid left in the pot.
To thicken the liquid, we wil make a cornstarch mixture and add it to the simmering contents to easily make the jam.
To make the cornstarch mixture, carefully take about ¾ cup of liquid content from the instant pot (may adjust the amount of liquid slightly as needed) and make a cornstarch slurry by mixing the cornstarch with the liquid.
Make sure to mix well so there are no lumps in the cornstarch mixture.
Add this prepared cornstarch mixture to the instant pot, quickly stir well with the contents so the cornstarch will evely mix with the contents in the pot.
Continue to simmer (and mash if needed) for another few more minutes (about 4 to 5 minutes or as needed) until the watermelon jam begins to thicken to jam consistency.
Press cancel button to stop further cooking and transfer the pot to a cool place so it won’t cook further.
Once the jam is slightly cooled, transfer the jam to air tight dry, clean glass jars.
This is a small batch jam prepared in the instant pot and not meant for canning.
You can store the glass jars with the jam in refrigerator for about two weeks time.
Notes: We have used seedless watermelon in this recipe to make the jam.
If you are using watermelon with seeds, make sure to remove the seeds before adding to the pot.
There could be some tiny seeds in seedless watermelon too, they are fine and as I explained in the instructions, you can remove many of those seeds while they are floating to the top during the process using a long spon.
A few tiny seeds that may remain in the jam looked fine to me.

So going to try this. But I am wondering why it can’t be canned.
Hi Kendell, I do not think instant pot jam is safe to be canned. We also use cornstarch in this jam recipe, an ingredient which is not meant for canning I believe. You can store this in the refrigerator for few days and in the freezer for some more time. Hope you like it! Thank you.
I made this. I ran into a problem. I didn’t have a potato masher so after the pressure cooking, I put in into the blender then back into the pot for the sauté part. Everything was going well until the cornstarch. I followed what was recommended but it wouldn’t smooth out, so I dumped that into the sink and did the tried and true cold water and cornstarch. As a result, I lost 3/4 cup of the juice and replaced it with water so I think that affected the flavor a bit. It’s still good, but not very watermellony but still yummy. Thank you for the recipe 🙂
Hi Kendell, Thank you for your feedback! It is important to make a smooth mixture of cornstarch without lumps before adding it to the instant pot, or it can affect the texture. I am sorry you lost some of the watermelon fruit, since the cornstarch didn’t mix well.
With regards to the flavor part, the flavor comes from the lemon juice and vanilla extract we use in the recipe since the watermelon flavor itself is not so strong when you cook it. Thanks again for stopping by, hope you will get even better results next time 🙂
The issue with adding the cornstarch to the watermelon juice is that the watermelon juice from the pot is hot. Cornstarch does not mix well at all with hot liquids, it needs to be cool which is why many recipes that use cornstarch say mix with cool water then add to the dish. Putting the juice in the fridge or freezer for a few minutes so it is cool will probably help. That’s what I did.
Hi Jessie, Thank you 🙂 It’s important that cornstarch need to be mixed well with the liquid without any lumps. If you find it difficult to mix it properly with the hot liquid, it’s always better to stick with the method of mixing with cold water (though it may increase the amount of extra liquid) to make the process easier. Thank you so much for sharing your thoughts on this, much appreciated!
This is DELICIOUS! I can’t tell you how surprised I was. I love watermelon, but the one my hubby picked out wasn’t the best. I hate wasting, so I looked for a recipe. This came up and man am I glad. I even put some on a piece of toast and told my husband to try (he’s the type to eat the store bought stuff before homemade). He said “wow this is good….really good”! I will definitely make this more often. I didn’t have any lemons and used lemon juice. Everything else was just like the recipe. Thank you!
Hi Susan, Thank you so much for the feedback! Much appreciated 🙂 I agree, this is such an easy way to use any leftover watermelons. I am so glad you and your husband enjoyed the jam. Thanks again!
