Why you will love this recipe!
This Strawberry Jam Recipe is one I have been using for many years and has been tried and tested with many different microwaves over that time. Whether you're an avid jam maker or have never made jam, this is a recipe you need to make.
Making fresh strawberry jam is extremely rewarding. For very little effort, you will produce two large jars of jam with the most delicious taste and fragrance to surpass any store bought variety.
I love making jam in the microwave for a few reasons. Firstly, I find that the fruit remains vibrant and there is less chance of burning the jam. For the novice jam maker, it can be quite daunting following stovetop jam recipes. Using the microwave simplifies the process.
Plus, it's so quick to make this strawberry jam recipe. Within 30 minutes, it will be ready. That's right! It's super easy and fast!
I just can't imagine serving my English scones with anything else!

Ingredients
Making this Strawberry Jam recipe is super easy and only takes 3 ingredients:
- Strawberries - Buy fresh strawberries at their peak when they are the most economical. Or use frozen strawberries. When I have too many strawberries, I'll hull and quarter them then pop the fruit into zip lock bags in the freezer for later.
- Lemon Juice - Be sure to use the juice of ripe lemons. If you don't have ripe lemons, use bottled lemon juice which has the correct amount of acidity required for jam.
- Sugar - White granulated sugar is best for this recipe. It will dissolve and help set the jam properly.
Instructions
- Cook quartered strawberries with lemon juice in the microwave for 5 minutes.
- Add the sugar and stir.
- Microwave on high for 15 minutes stopping every 5 minutes to stir.
- Ladle into sterilized jars while hot and seal with the lids immediately (protect your hands with a thick towel). Allow to cool to room temperature before storing in a cool, dry place for up to 6 months.
Tips for success and FAQs
- Sugar is needed to set and preserve the jam. If the sugar is reduced in this recipe, the result will be thin, runny jam that doesn't keep very well. I don't recommend reducing the sugar in this recipe!
- Don't under cook. Undercooked jam will taste fresh but may separate as it cools.
- Avoid doubling or tripling the batch. This strawberry jam recipe will boil up and bubble over if you make more than this quantity.
- This recipe has no added pectin but uses lemon juice to assist with setting.
Strawberries and other low acid fruit need the acid from lemon juice to help set the jam. It is a science which I am not going to explain here but you could research it yourself. To help set the jam even further, you can cook the jam with a little muslin pouch of lemon rind and seeds which contain lots of pectin.
Another reason for adding lemon juice is to make the jam safe and prevent growth of mold and bacteria and preserve the jam.
Sterilize in a water bath by placing the jars and lids in a large pot and covering with cold water. Bring to the boil and boil for 10 minutes. Remove from the boiling water with tongs and drain on a paper towel lined baking sheet. Any excess can be patted dry with paper towel.
Alternatively place upright jars and lids in a preheated 250ºF/120ºC oven for 20 minutes.
This strawberry jam recipe needs to be microwaved on high power for at least 15 minutes after adding the sugar to ensure a good set. Be sure to stir at 5 minute intervals.
After 15 minutes you can begin testing by dropping about ½ teaspoonful on a cold saucer. Place the saucer back in the fridge and after a few minutes check if the jam has jelled. I usually find I need 3 - 5 minutes more.
Also the sugar and lemon juice work with the pectin in the strawberries to ensure a good set.
Store the jam in a cool dry place for up to 6 months and once opened use within 2 months. However for longer shelf life, store in the fridge or freezer. Filled jars can also be processed in a water bath. There is lots of sites and books that explain water bath processing fully.

Quick & Delicious Strawberry Jam
Equipment
- 4 litres/16 cups capacity microwave safe bowl
Ingredients
- 4 cups hulled and quartered strawberries (approx 1 pound or 500 grams) hulled and quartered
- ¼ cup lemon juice (60mls)
- 2 cups sugar (400 grams)
Instructions
- Place strawberries in a large (4 litres/16 cups capacity) microwave safe bowl with the lemon juice. Microwave on high for 5 minutes. It should start smelling amazing already. Remove from microwave.
- Once you add the sugar the fruit won't break down much more so if you want it smooth cook for a little longer.
- Add the sugar and stir to dissolve.
- Return to the microwave, cook for 15 minutes on high, stopping every 5 minutes to stir and check. The jam will come to a full rolling boil. Don't leave unattended just in case it boils up and over the bowl.
- Pour into sterilized bottles. Seal.
Notes
- Be sure to use a very large bowl. The one I use has a capacity of 4 litres or 16 cups. The strawberry jam will boil up and spill over if you have a small bowl and you'll have a sticky mess!
- Don't leave unattended while cooking just in case the strawberry jam boil up and over the bowl.
- Sterilise jars in the microwave by washing and rinsing well. Leave jars wet and cook in the microwave for 60 seconds on high. Be careful when removing from microwave oven - they will be hot. Fill with strawberry jam and seal immediately.

Do I have to refrigerate the jam?
Marcellina
Hi Anna! Store the jam in a cool, dry place for up to 6 months and once opened use within 2 months. However for longer shelf life, store in the fridge or freezer. Filled jars can also be processed in a water bath.
Either way, be sure to sterilize the jars (by either boiling the jars and lids in water for 10 minutes or placing jars and lids in a 250ºF/120ºC oven for 20 minutes) then fill hot jars with hot jam and seal with the lid immediately.
Thanks for the query! I've updated the post to reflect this.
