Easy Strawberry Freezer Jam

Once you try this delicious, super fresh-tasting, Strawberry Freezer Jam, you’ll be spoiled for life. I call it “springtime in a jar”! It’s like a little dollop of heaven on toast, biscuits, scones, ice cream, yogurt…

I posted this recipe for Strawberry Freezer Jam back in 2012 and again last year, in 2019 but I decided to bump it back up to the top of the blog again for several reasons. First of all, I just made a big batch and it’s so darn good, I wanted to make sure that all of newer readers had the chance to enjoy this recipe. Secondly, I made some pretty labels for the jars and thought some of you might like them for gift-giving as well as for keeping things organized. My freezer is getting re-stocked with glistening (labeled) jars of this wonderful jam and I thought you might want to make some too – before the fleeting local strawberry season disappears!

Spring has definitely sprung here in the mountains of North Carolina and summer is just around the corner. The days are cool, sunny and gorgeous with lovely blooms and trees now fully dressed in vibrant green.

One of my favorite aspects of this lovely time of year is enjoying the short, but gloriously delicious season of local strawberries. One bite of a deep red, juicy strawberry, picked just hours before, makes you realize that the store-bought variety you’ve been eating for the past few months… well, perhaps they weren’t really strawberries, after all.

I love to capture this delightful time of year with this delicious Strawberry Freezer Jam. And when those short, dreary winter days roll around (always too soon), all I have to do is pull out a jar of this crimson sunshine and I’m instantly transported to warmer days. Because freezer jam isn’t cooked down on the stovetop, it explodes with fresh, vibrant flavor and color.

A perfect recipe for beginners!

If you’ve never made jam before, this Strawberry Freezer Jam is a wonderful place to start as it’s super easy and doesn’t require any canning knowledge. There’s no water bath, canning pots or sealing techniques involved (as in traditional jam-making methods). Simply stir together the jam (instructions below) and ladle it into clean glass jars or plastic storage containers. Pop the jars in the freezer and you’re done, it’s really that simple.

Drawbacks to making freezer jam?

These are the two potential problems with freezer jam:

1. A grainy consistency. Because it’s not cooked as traditional jam is, it can be difficult to dissolve all of the sugar. If the sugar’s not completely dissolved the finished jam can have a “grainy” or “sandy” consistency.
2. The jam doesn’t “set” (thicken) properly. It’s frustrating to go through all the trouble of making jam and end up with it not setting.

How to make freezer jam that’s not grainy

I’ve been making freezer jam for as long as I can remember and, over the years, I’ve developed a few simple steps to overcome this “grainy” problem:

• A short stint in the microwave will help dissolve a lot of the sugar without actually cooking the mixture and dulling the flavor and color.
• Be sure to stir the jam well (as in VERY WELL.) Don’t cheat on the stirring time both before and after the pectin is added. I like to actually set a timer to make sure I’m stirring for the full instructed time. This is a great project to give to your kids. They’ll enjoy being part of the process and will be so proud when they see the beautiful jars of jam lined up on the counter.
• Don’t follow the instructions on the pectin packet. The jam is supposed to be ready for ladling into jars in 20 minutes. It takes quite a bit longer than this for the sugar to dissolve into the berry mixture. (But it’s mostly hands-off time, time you can be doing something else.)

 How to make sure jam thickens

• This problem can occur with traditional jams and jellies to but seems to be more prevalent with freezer jam. However, the same little tricks (see above) that I use to combat graininess will also ensure that the jam “sets” properly. When the sugar is well dissolved the jam will thicken when combined with the pectin.
• Don’t cheat on the measurements. Unlike other types of cooking, jam making is an exact science and proportions of fruit to sugar are important. So measure your ingredients carefully. Don’t add extra berries just because you have them. Use the extra berries for snacking or make an ice cream topping but don’t throw them in the jam bowl.
• Check the date on the pectin box. Pectin can get old and lose its oomph. If your pectin is expired, discard it.
• Be sure to use all of the liquid pectin. I use Certo pectin. It comes in a box with two packets inside. It’s important to squeeze all of the pectin from the packet. I like to roll it up as I squeeze it out to make sure I get every last drop.

One of our very favorite ways to enjoy this Strawberry Freezer Jam is on these Ridiculously Easy Buttermilk Biscuits. If you haven’t tried them, you’re really missing out on something WONDERFUL. But don’t believe me, check out all the 5-star reviews!

As I mentioned above, I made some labels this year for the strawberry jam. If you’d like a printable PDF for the labels, just leave me a comment below and I’ll get it off to you. The labels can either be glued to the top or side of the jar or slipped inside the ring on the top of a mason-type jelly jar.

Café Tips for making this Strawberry Freezer Jam

• Be sure to note tips above regarding problems with graininess and jam not setting.
• Although there’s very little hands-on time when making this Strawberry Freezer Jam, make it on a day when you’re going to be around the house. You’ll need to give it a good stir every now and then to help dissolve the sugar.
• One way to know when the jam has been stirred enough and is ready for the pectin is that the color will become deeper red. If your strawberry/sugar mixture still looks a bit cloudy, you probably need to stir it more or give it one more 3-minute stint in the microwave.
• Certo is a liquid fruit pectin that helps thicken the jam. Certo can usually be found in the same section of the grocery store as canning jars and storage containers. If you can’t find it, just ask at the front desk and someone can direct you to the right section of the store. Don’t use powdered pectin for this particular recipe. They are not interchangeable.
• Check the label on the Certo before buying to make sure it’s not expired. It can lose it’s thickening properties if it’s old.
• Don’t skip the lemon juice. Lemon juice has lots of natural pectin which helps in combination with the Certo to thicken the jam.
• Some people are concerned about freezing jam in glass jars. I’ve been doing this for over 40 years and have never had a jar break. You do want to make sure however that you leave about a half-inch of space at the top of each jar to allow for expansion when the jam freezes.
• You can also use plastic storage containers if desired.
• This jam is fine at room temperature for a few hours but store it in the refrigerator or freezer when not being used.
• If gifting this Strawberry Freezer Jam let the recipient know that this jam should be stored in the refrigerator or freezer when not being used.
• The jam won’t set completely right away, hence the instructions to allow it to sit on the counter for 24 hours. Plus, I love the look of beautiful, vibrant red jam stacked up on my kitchen counter – call me old-fashioned, but there’s something about it that makes me smile!
• I love these Weck Jars. They make lovely gifts and a pretty presentation when serving this Strawberry Freezer Jam.

If you’ve never made Strawberry Freezer Jam you REALLY need to try this recipe – I promise you won’t be disappointed!

Easy Strawberry Freezer Jam

The most delicious, fresh tasting jam. Once you try it, you'll be spoiled for life. I call it "springtime in a jar".

Author: Chris Scheuer

Course: Jam

Keyword: Easy Strawberry Jam, Strawberry Freezer Jam, Strawberry Jam

Prep Time: 30 mins

Cook Time: 3 mins

Total Time: 2 hrs 33 mins

Servings: 80 Yield:1 tablespoon servings

Calories: 40 kcal

Ingredients

• 4 cups granulated white sugar
• 1 quart about, see exact measurement below fresh strawberries
• 3 ounces liquid fruit pectin I use one pouch. of Certo which is readily available at most larger supermarkets. One pouch is 3 ounces or 88ml.
• 2 tablespoons fresh lemon juice

US Customary - Metric

Instructions

1. Wash and rinse glass jars (or plastic containers) and lids in the dishwasher or with hot soapy water. Dry thoroughly.

2. Stem and crush strawberries. Don't try to use a blender or food processor for this step as you want some small pieces of strawberry to remain. (I like to use a potato masher).

3. Measure exactly 2 cups prepared fruit into a large microwave-safe bowl. Add the 4 cups of sugar and stir well for 1 minute.

4. Place the bowl in the microwave on high power for 3 minutes. (Mixture will not cook but will become warm enough for sugar to dissolve). Remove from microwave and stir well for another minute.

5. Allow strawberry mixture to sit for 2 hours, giving it a good stir about every 30 minutes. Take a taste to make sure the sugar is dissolved. If it still has a bit of a grainy texture, stir for another minute or two until sugar is well-dissolved.(When the sugar is well-dissolved the mixture will actually deepen in color and lose it's "cloudiness". That's when you're ready for the next step.)

6. Combine the liquid pectin and lemon juice in a small bowl. Add to strawberry mixture; stir 3 minutes.

7. Fill containers to within 1/2 inch of top- don't fill any higher as mixture will expand a bit in the freezer.

8. Wipe off top edges of containers and cover with lids. Let stand at room temperature 24 hours.

9. Refrigerate up to 3 weeks or freeze up to 1 year. Thaw in refrigerator.
