Homemade Strawberry Jam with Pectin
There’s something about a pot of strawberry jam on the stove that feels like the start of summer. The windows are open, the kitchen smells sweet and bright, and for a little while, everything slows down.
This version of strawberry jam is a little different from a store-bought jar of the classic full-sugar kind. It’s slightly softer, a bit more spoonable, and lets the fresh flavor of the berries shine through. Not stiff or overly sweet—just a gentle, homemade jam that tastes like real strawberries.
If you’ve never made jam before, don’t worry, I’ll walk you through it. And if you have, you’ll find this one to be an easy, forgiving recipe to keep in your back pocket to pull out when the berries are at their best. All you need are a few simple ingredients, a good pot, and a little patience. The rest comes together just as it should.

Why I Use Pectin in This Strawberry Jam
Strawberries are delicious for jam, but they aren’t naturally high in pectin. That means they can be a little unpredictable on their own, especially in a lower-sugar recipe like this one.
Adding pectin helps the jam set more reliably without having to cook it down for a long time. It keeps the process simple, makes this recipe more beginner-friendly, and still lets that bright, fresh strawberry flavor come through.
Is this a low-sugar jam recipe?
This jam uses a bit less sugar than some traditional recipes, which lets the strawberries shine a little more. It’s not quite a low sugar jam, though. The sugar actually does important work here, helping everything set and come together just right. I’ve found this balance gives the best results.
Why This Jam Has a Softer Set
This strawberry jam is meant to be a little softer than traditional, full-sugar jams. With less sugar and a shorter cooking time, the texture stays more spoonable and closer to the natural consistency of the fruit.
Instead of a firm, store-bought-style set, you’ll get a gentle, homemade jam that spreads easily and lets the fresh strawberry flavor shine through. It may even seem slightly loose when warm, but it will thicken as it cools—and that softer texture is part of its charm.
Ingredients for Strawberry Jam with Pectin:
🍓 A Quick Look at the Ingredients
- Strawberries: Fresh, ripe strawberries give this jam its flavor. It’s fine if a few less ripe strawberries are included, though, as they are higher in pectin and will help the jam set.
- Powdered Pectin (low or no-sugar needed): This helps the jam set without requiring as much sugar. It makes the process quicker and more reliable, especially for beginners.
- When shopping for pectin, look for a box labeled “low or no-sugar needed pectin.” It’s usually sold in small boxes or jars near the canning supplies and may be labeled for reduced-sugar or no-sugar recipes. You can also find it in bulk at some stores or on Amazon.
- Be sure to choose powdered pectin, not liquid pectin, as they are used differently and aren’t interchangeable in this recipe.
- Common brands include Sure-Jell (low or no-sugar version) and Ball RealFruit Low or No-Sugar Pectin.
- Granulated Sugar: Sugar does more than sweeten—it helps the jam thicken and preserves it. This recipe uses less than traditional jams, but still enough for a proper set.
- Lemon Juice (optional): Adds a touch of brightness to the flavor and supports the setting process. It’s not strictly required, but it rounds everything out nicely.
Tips for Making Homemade Strawberry Jam
Don’t skip this section. I’ve included helpful information and tips for making your best homemade strawberry jam.
Finishing Your Jam: What to Look For and What to Know
As your jam cooks, it will begin to thicken slightly and take on a glossy, rich look. It won’t seem very thick in the pot—and that’s perfectly normal. This is a softer-set jam, and it will continue to thicken as it cools.
How to tell if it’s ready
If you’d like a little extra reassurance, place a small spoonful on a cold plate and let it sit for a minute. Gently push it with your finger—if it scrunches up and holds its shape, it’s ready.
After cooking
Once the jam is finished, ladle it into prepared jars and process according to safe canning practices, or allow it to cool and store it in the refrigerator or freezer.
Labeling your jars
Before setting them aside, label your jars with the date and contents. It’s a small step, but one you’ll appreciate later—especially when you come across a jar months from now and can’t quite remember when you made it.
If your jam seems too soft
Strawberry jam made with less sugar will naturally have a gentler set. Give it 24 to 48 hours to fully cool and thicken before deciding if it needs any adjustments.
And when all is said and done, don’t worry too much about perfection. Some of the best jars are the ones that turn out just a little softer—easy to spoon, a bit drippy on warm toast, and full of that fresh, bright strawberry flavor that made you want to make jam in the first place.
A Little Note on Safety
Hot jam is much hotter than boiling water, and the sugar can cause serious burns if it splashes. As you cook and ladle the jam, move slowly and stir gently to avoid splattering.
Use a deep pot to give yourself plenty of room, and be careful when transferring the hot jam into jars. Taking your time here makes all the difference.
It’s a simple process, just one that’s best done with a little extra care.
🍓 Storage and Shelf Life
Once your jam has cooled, there are a few simple ways to store it, depending on how you plan to use it.
Refrigerator Storage
If you’re planning to enjoy your jam right away, you can store it in the refrigerator.
- Let the jam cool completely
- Cover and refrigerate
- Use within about 2–3 weeks
Freezer Storage
For longer storage without canning, the freezer works beautifully.
- Allow the jam to cool
- Transfer to freezer-safe containers, leaving a little room for expansion
- Freeze for up to 6 months
Thaw in the refrigerator when ready to use.
Canning for Shelf Storage
If you’d like to store your jam at room temperature, it can be preserved using a standard water bath canning method.

Easy Homemade Strawberry Jam (with Pectin)
- Total Time: 45 minutes
- Yield: Approximately 8 half-pints
Description
A delicious Homemade Strawberry Jam made with pectin and bursting with strawberry flavor.
Ingredients
- 6 cups crushed strawberries (buy 4 pounds, but you might have some extra)
- 1 (1.75 oz) package low or no-sugar-needed powdered pectin (about 6 tablespoons)
- 4 cups granulated sugar, divided
- 2 tablespoons lemon juice – this is mainly for flavor. You may use fresh or bottled.
Instructions
- Wash and hull the strawberries (remove the green tops), then crush them using a potato masher. You’re looking for a juicy, pulpy mixture with some small pieces remaining—not large chunks. Measure out 6 cups of crushed strawberries.
- In a large, heavy-bottomed pot, stir together the crushed strawberries, powdered pectin, ¼ cup of the measured sugar, and the lemon juice. Bring to a full rolling boil that cannot be stirred down, stirring constantly.
- Add the remaining sugar, stirring to dissolve. Return to a full rolling boil, then boil for exactly 1 minute, stirring constantly.
- Remove from heat and skim off any foam if needed.
- Ladle the jam into clean jars or freezer-safe containers.
- For refrigerator storage, ladle the jam into clean jars, allow to cool, then add lids and refrigerate for up to 2–3 weeks.
- For freezer storage, allow the jam to cool for 15 minutes, then transfer to freezer-safe containers, leaving an inch or so of headspace for expansion. Allow to cool, and freeze for up to 6 months.
- For canning, ladle the hot jam into hot, clean canning jars and process for 10 minutes using the standard water bath canning method, adjusting for altitude. (For more about canning jam, see the notes below).
Notes
Start with enough berries. You will need about 3 to 3 1/2 pounds of fresh strawberries, but it is best to start with 4 pounds to allow for trimming, discarding any bruised or spoiled fruit, and natural variation.
Remove the hulls. Be sure to hull the strawberries before crushing, as the green tops can affect both flavor and texture.
Measure the strawberries after crushing. For best results, crush first, then meassure out 6 cups of crushed strawberries.
About the pectin. This recipe uses a standard 1.75 ounce package of low or no-sugar-needed powdered pectin, such as Sure Jell or Ball RealFruit.
Using bulk pectin from a jar. If your pectin comes in a jar, measure out 1.75 ounces by weight to match one box. If you do not have a kitchen scale, this is roughly equal to about 6 tablespoons, but measuring by weight is the most accurate.
Not for two-part pectin systems. This recipe is not designed for two-part pectin systems such as Pomona, which use a different method and ratios.
Do not reduce the sugar. Even though this recipe uses less sugar than traditional jam, the amount here is important for proper setting and texture.
Give it time to set. The jam will thicken as it cools and will continue to set over 24 to 48 hours.
Learning to can. Canning is a simple process, but to do it safely, you need to learn the proper procedure. I recommend finding a good tutorial online or in a book. I recommend the Ball Complete Book of Home Preserving [affiliate link], or this Water Bath Canning Guide on the Ball website.

Is it possible to use regular pectin in this recipe or does it have to be low sugar?
It needs to be pectin made for low-sugar or no-sugar recipes, otherwise, the jam probably won’t set. The reason for this is that this recipe doesn’t contain as much sugar as many classic jam recipes do. However, low sugar pectin should be easy to find at your local grocery store. I like both the Sure-Jell and the Ball brands.
If I used the regular pectin, do you have a suggestion to help make it set? It’s my first time making it and I followed everything else. Tastes delicious just hasn’t set.
Unfortunately, the jam won’t set if you use regular pectin because it doesn’t have enough sugar to do so. You really need to use pectin that is made for low-sugar or no-sugar jam for this particular recipe. (I’m sorry, I know this probably isn’t the answer you wanted to hear.)
But there is some good news. What I do when a jam or jelly fails to set is to call it syrup. You can use it on pancakes, ice cream, waffles, or add it to a pitcher of lemonade. There are so many delicious uses for strawberry syrup!
There is one other possibility, but it’s something I almost never do myself. But you can remake the jam. You will need to add more pectin and reprocess the jam. If this is something that interest you, you can read more about it here: Remaking Soft Jellies
I hope this helps!
I am in the middle of making my strawberry jam, but you said to; crush them with a potato masher, I am having a hard time with this, for as they are not mashing well?
You can use any utensil that works for you to crush the strawberries. And it’s OK if they aren’t completely mashed and are still a little bit chunky.
Can you tell me how to break down pounds by cups? Or can you? I don’t have a scale
Thanks

It will be about 15-16 cups of strawberries. Here is a guide that should help: Strawberry Measures and Equivalents
I’m preparing to make this but ended up with 6 pounds of strawberries. I assume I should go with 6 cups of sugar. How should I adjust the water and pectin?
Thanks!
It can be tricky to increase the quantities in a jam recipe. For some reason, the jam sometimes doesn’t set properly. If you want to use all 6 pounds of strawberries, I would use 6 cups of sugar, and 1 1/2 cups of water. But I would double the pectin to 8 tablespoons, just to be sure to get a good set. If you try it, let me know how it turns out!
I used this conversion without really reading the entire article. I didn’t see I was supposed ti 7se low surgar pactin. I used certo pectin and it didn’t set up. It has been 24 hours. What should I do to make this work or is it to late? Any help would be appreciated.
So sorry to hear about this! I know how frustrating it is when your jam doesn’t set! In this situation, I usually do one of two things. One option is to use the jam as a strawberry syrup. You can use it on pancakes and waffles, drizzle it over cheesecake, add it to lemonade, etc. The second option is to remake it, which essentially means to recook it. If you choose this option, be sure that you are using powdered pectin that is made for NO SUGAR recipes. You will also need to add lemon juice. This article HERE gives complete instructions on remaking runny jam. I hope this helps!
Thank you so much! I can’t wait for the strawberries !
i plan to use your recipe when the really frsh strawberries are in season I have some questions in order to ensure success- when using pectin do i need lemon juice too< and does the jam need to reach 220 degrees, and could you please recommend a particular pectin? Thanks in advance!
You don’t need lemon juice for this particular recipe. And you won’t need to use a thermometer to check the temp. Simply bring the jam to a boil and boil hard for 1 minute. As for brands of pectin, I typically use Sure Jell or Ball. But you can use any powdered pectin as long as it is one that is formulated for using less sugar or no sugar. Hope that helps!
What do I do when my jam doesn’t set and is still runny? I followed the recipe. I had some peach jelly to do that one time and I just emptied it into a pot and boiled it until I did the sheet test on the back of a spoon. Would that process work on this jam too?
I’m sorry the jam didn’t set for you. Unfortunately, it does happen sometimes. There are 2 things you can do. The first thing is to just wait. I recently made a batch of blackberry jelly that didn’t set right away. I allowed it to sit in the jars on my counter and after 3 days it set and became firm. The other thing is to do exactly what you just said you did with the peach jelly. Here is a link to the instructions from the National Center for Home Food Preservation: Remaking Jams and Jellies. I hope this helps
In the instructions (#4) you say to process for 10 minutes. What does that mean? Let them sit? Or something else? Thank you 🙂
It actually means to process in a boiling water bath canner for 10 minutes. You don’t want to just allow the jars to sit. They lids may seal, but that’s a possibly unsafe process known as open kettle canning.The National Center for Home Food Preservation has safe and easy instructions for proper boiling water canning that you can follow here. If you don’t want to can the jam, you can just pop it in the freezer.

Thank you, Miz Helen! I hope you have a happy July 4th!
I love homemade jams and this recipe sounds like a keeper! Could I use peaches instead of strawberries with this recipe? Not that I don’t love strawberries, but I just ordered 25 lbs. of peaches.
Hi Terri, I haven’t tried this recipe with peaches so I can’t say for sure if it will work. Most peach jam recipes call for added lemon juice, although I suspect this is probably to keep the peaches from turning brown. I like this recipe by Sure Jell for peach jam. Also, be sure to use only yellow peaches for jam as the white peaches are too low in acidity for water bath canning. I hope this helps!
How many jars of jam does this recipe make?
It makes approximately 8 half-pints.
I just received my 25 pounds of peaches. I peeled them and cut peaches and used my seal a meal to seal them and put them into my freezer. Then I took my peelings and pits and covered in water and brought to a rapid boil and boiled them for 30 minutes. Then strained the juice out with a fine strainer or cheesecloth. I put juice up overnight in my refrigerator. Next day I prepared my jars. And used filling recipe to make jelly.
3 1/2 cups of the juice
1/2 tsp of real butter
1 box of pectin
Bring to a rapid boil
Then add 4 1/2 cups of sugar and keep stirring untilit reaches a rapid boil again. The boil for 1 minute. Then set aside from burner and ladel into your jars. This make 6 half pint jars.
I still have more juice to process in my refrigerator. And will continue the recipe until I use up my juice and what I have left will make some peach syrup for pancakes.
