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.

I am going to be trying this recipe next week. I live at an elevation of 7200 ft. It said see notes for canning time for elevation, but I am not see that?
Here is a chart by Ball Canning that will give you the correct time for altitude:
I hope this helps!
Well, I didn’t read the article and used regular pectin. Is this a safety concern or mainly for set up?
It’s to ensure setup. So no worries, it’s not a safety concern.
I love jams over jelly, containing bits of the fruit used. I made this recipe almost exactly as recommended by the author. I did the thick jam with the most pectin which is still a nice spreadable jam. I share the author’s preference for using pectin to maintain the flavor & the taste of strawberries. No one in my family is allergic or has an aversion to pectin. My first batch was made using just sugar and a longer cook. It turned out well, but not the preferred consistency of jam from this recipe. Side by side tasting by family members was unanimous. Jelly with the pectin won. The only thing I added to this recipe was the juice from one freshly squeezed lemon. Yes, this will continue to be my go to for Strawberry jams. Thank you Melissa ♥️
You are very welcome! I’m so happy that you and your family like the recipe! It’s our family’s favorite.
I made your recipe and did the water bath for canning. The jam is delicious and perfect….BUT I am fairly new to canning and in my recent reading I have learned I am supposed to add lemon juice to the jam for the PH and to be safe for consumption.
Is this true? Or will my jam be ok?
If you followed proper canning procedures, then the jam is perfectly safe to eat! When you are water bath canning, you need the food in the jar to be at a pH of 4.6 or lower. The heat of the boiling water kills the microorganisms, but it’s the acid in the jam that will prevent bacterial spores (like botulism!) and from forming in the anaerobic (low oxygen) environment of the sealed jar. As strawberries are in the pH of around 3 – 3.5, they are well in the safe range. We call this a high acid fruit, and so they do not need added acid like lemon juice to be safe. In fact, most (but not all) fruits are considered high acid foods and do not need to be acidified in order to be safely canned. Bananas, melons, white peaches, and a few other fruits can’t be safely water bath canned without adding acid.
But you will find there are jam recipes that call for added lemon juice. This can be to lower the pH, or for simply for flavor, or to help the jam set (acidity is also a factor in the gelling of a jam or jelly). Also, tomatoes are right on the cusp of being at a safe level of acidity, so you MUST add bottled lemon juice or citric acid when canning. For more information on the subject, the Ball canning books are a good source. Also, the National Center for Home Food Preservation website is a great resource. And please know that I will never share a canning recipe that isn’t safe. I’m not a food scientist, but I am a biologist by education, and I take food safety very seriously. I hope this helps!
I also wanted to give you a link to the National Center for Home Food Preservation recipe for canning strawberry jam. They are funded by the USDA and are one of the “official” sources for safe practices for home food preservation. Their recipe contains only sugar, pectin, and berries. I hope this reassures you as to safety. There is a lot of interesting information about canning on the internet, so if in doubt, it’s best to go to an official source for your information. NCHFP recipe for Strawberry Jam.
What should I do with the calcium powder included?
So if your pectin includes a calcium packet, I’m going to assume that you are using Pomona’s Pectin. That is a different type of pectin that requires the addition of the calcium packet dissolved in water. It won’t work with this specific recipe, but Pomona has their own strawberry jam recipe that you can use. You can get the recipe on their website . I hope this helps. And I’m sorry for the confusion. I am going to update the recipe to indicate that it won’t work with Pomona’s.
How many jars of jam does this make??
I’ve found that using pure cane sugar as opposed to granulated sugar does better making it gel. The store brands of granulated sugar use both cane and beet sugar and didn’t work well for me.
This recipe proved to be delicious and a beautiful bright red color, but really didn’t jell well yet I do have a very nice soft jam that is tasty. I processed in water bath for 10 min and all sealed. Will this soft jam keep sealed at ROOM temp, or need to refrigerate?
Also if would be helpful to give measurements of amt. crushed berries. Thx!
It’s very likely that your jam will firm up over the next week or so. Just allow the jars to sit undisturbed in the pantry or another cool place. And as long as you used approved canning procedures from Ball or another reputable source, your jars of jam are shelf stable, so no need to refrigerator your sealed jars.
And that is a great idea about adding the measurements for the crushed berries. I will definitely do that. From my calculations, it should be approximately 7-8 cups of crushed strawberries. And here is a link to a website that gives conversions for different amounts of strawberries: Strawberry Measures and Equivalents
How long will it stay stable for? Another recipe I was looking at said 10 days but it didn’t have pectin.
What size canning jar do you use and how many?
The recipe makes *about* 6 pints. So you’ll need 5-6 pint jars, or 10-12 half pint jars.
