This low sugar no pectin strawberry jam recipe is our favorite. Step-by-step tutorial for a homemade strawberry jam without pectin and tons of flavor. Every home needs an easy strawberry jam recipe without pectin (specifically store-bought pectin) and low sugar. Because I'm a firm believer your jam shouldn't have more sugar than it does fruit.

Like any pioneer woman, the beginning of summer marks jam and jelly season on our homestead. Whether its fresh-picked cherries for homemade cherry jam, juicy and plump blackberries for blackberry jam or even juicy peaches for this amazing spicy peach jam. Fingers are sure to be stained with the berry of the moment and snack breaks are taken at the bush with the ripest fruit.
Homemade strawberry preserves are the first berry recipes to hit my canning jars come spring. My husband loves strawberry jam, it is his absolute favorite. I've yet to meet a jam I didn't like, but he's partial to this one.
If you're nervous about canning, don't be! Read here about safely canning jams and jellies, and this is a fantastic canning 101 post that every new home canner should read.
One of the reasons we preserve our own food is so we have a fully stocked pantry that isn't dependent upon the grocery store, is healthier without chemicals and GMO ingredients, and to save money. Using a strawberry jam recipe without store-bought pectin and low sugar keeps us within these guidelines and is how the pioneers and our great-grandmother's made jam. Because I want my homemade strawberry jam to taste like strawberries, not a bucketful of sugar.
Resources for Easy Homemade Strawberry Jam
If you already have jars (canning jars will last for decades as long as they're not chipped), then your only cost is for lids, sugar, and lemons (we're assuming you're growing your strawberries, but if not, then there will be the cost for those as well). The good news for this recipe is there's no need for store-bought commercial pectin which cuts your cost even more with this low sugar no pectin strawberry jam recipe.
To can strawberry jam you'll need:
- Canning Jars
- Canning Lids & Bands
- Large Canning Pot
- Funnel & Canning Tools
- Towel
- Strawberries
- Sugar
- Lemons
How To Freeze Strawberry Jam
You absolutely can freeze this strawberry jam instead of canning it. However, we prefer to can it over making a freezer jam because we like to be prepared for power outages, and no one wants to eat gobs and gobs of jam if the power goes out (OK, maybe we do…but it's not ideal!).
This recipe can be canned, as described, stored directly in the refrigerator (best within 4-6 weeks) or stored in the freezer (best within 2-3 months). Just be sure to cool jam completely before placing in the freezer to prevent jars from cracking.
Healthier Strawberry Jam Recipe
What makes this strawberry jam recipe healthy? Well, I don't know about you, but a homemade jam that contains more sugar or as much sugar as it does fruit just doesn't sit right with me.
Not only is this low sugar strawberry jam recipe healthier, but it's also much more frugal without pectin from the store and loads of sugar. (And I have a no sugar strawberry jam option too.)
Plus, I'm all about recipes that don't rely on store-bought items. Does anyone else feel they were born a century too late and should have been besties with Laura Ingall's Wilder in Little House on the Prairie? You, too?! Good, grab your apron, your Mason jars, and let's get to jamming.
Sources of Natural Pectin
Lemon and apples are both very high in natural pectin. My grandmother never used pectin and you don't have to either. We're using lemon juice in our recipe to naturally set our jam. It may not seem like it's going to work but trust me, you just have to cook it a bit longer than the store-bought pectin recipes… but it will get there, I promise!
Surprisingly, you just get a hint of the lemon, so if you want it to be stronger, add the juice of one more lemon. Think strawberry lemonade in a jam. Oh, yes, don't mind if I do.

Can I Make Jam Using Frozen Strawberries?
Although it's not ideal to use frozen strawberries for this recipe, they will certainly work. Just understand your cooking time will be much longer due to the extra water content of the frozen berries. No need to defrost berries first, just toss them into the pot and let them defrost as you crush them up.
How To Fix A Jam That Didn't Set Up
If your jam is not fully set after canning, you can fix it! Don't despair! All your hard work has not gone to waste. Before you open each jar, be sure your jam is completely cool. Jam continues to set up as it cools, so it may just be that your jam is still too hot.
If your jam is still runny once cooled to room temperature, simply open up all your jars and dump the jam back into your pot. Continue cooking until your jam passes the sheeting test.
The sheeting test means your jam will be thick enough to stick to the back of a frozen spoon without dripping off (or it may come off in one sheet!). But if you get little drops or even larger drops of jam, you'll want to continue cooking it to allow it to thicken further.
How To Make Homemade Strawberry Jam
Instructions for canning homemade strawberry jam:
- Wash jars and bands in hot soapy water and keep warm. Fill water bath canner with water and put on medium heat.
- Add fresh strawberries to the pot. Crush strawberries with a potato masher or immersion blender to desired consistency (could also puree in the blender first). I prefer mine chunky, but my husband likes it more pureed.
- Place strawberries, sugar, lemon juice, and lemon zest into a large pot. Stir until well combined and sugar is dissolved. Bring berries to a boil (if you have a candy thermometer jam sets at 220 degrees Fahrenheit, taking out the guesswork). Stir frequently to keep sugar from scorching.
- Simmer on a low boil for 20 minutes stirring constantly. You can test the set of the jam by the sheeting test. Place a metal spoon in the freezer when you begin making your jam. Cooking time will vary depending on the water content of the berries.
- After the 20 minutes of boiling, use the chilled metal spoon to ladle out a spoonful of jam. Hold the spoon and watch the way the jam drips off of the spoon. If its little individual drops, the jam is not set, if it’s big goops, it’s almost there. If it comes off the spoon in a sheet or doesn’t really drop off at all, then the jam is set, yank that baby off the heat.
- Place jars on a dishtowel. Fill jars leaving a ¼ inch headspace (1/4 gap from the top of the jam to the top of the jar). A canning funnel will be your best friend during this part.
- With a clean damp towel, wipe down the rim of the jar. Place lids on, then bands, and screw down to finger tight.
- Immerse jars in boiling water bath canner inside the canning rack, making sure water covers the tops of the jars by 1 to 2 inches. Once water is boiling, set timer for 10 minutes and allow jars to process.
- When time is up, turn off the heat. After 5 minutes remove jars from canner. Place on a towel folded in thirds in a draft-free area. Allow to cool and set overnight or for at least 12 hours. Check seals. If the center of the lid gives, then store in the refrigerator and eat soon.
- If jars are sealed, wipe down with a damp cloth and store in the pantry out of the light for up to a year.
Makes approximately 4 half-pint jars
Note: Always inspect your jars of jam and jelly before using it. If the seal is broken, if the jar is leaking, if you detect an off odor, off appearance, or any signs of mold, do not eat or taste it. Throw it out.
Check the seal when you go to use a jar, even if it sealed when you put it in the pantry. Seals can sometimes come undone over time.

Instructions
- Wash jars and bands in hot soapy water and keep warm. Fill water bath canner with water and put on medium heat.

Notes
- Because we're not using store bought pectin the cook time to reach a gel point can vary based on the ripeness and water content of your berries at harvest.
- Liquid or pureed berries take longer to reach the gelling point
- One reader wrote in saying the lemon flavor in a batch she did that didn't set was strong, but after re-cooking the jam until it reached its gelling point, the lemon flavor is barely detectable.
- Please download the free Never Buy Jam or Jelly E-book with our troubleshooting guide if your jam is not gelling for help.
- Always inspect your jars of jam and jelly before using. If the seal is broken, the jar is leaking, off odor, off appearance, or any signs of mold, do not eat or taste it. Throw it out. Check the seal when you go to use a jar, even if it sealed when you put it in the pantry. Seals can sometimes come undone over time.
