This easy strawberry jam without pectin is a classic homemade preserve everyone should try. It yields a sweet, gently set jam made with just three ingredients and a short simmer on the stovetop.
If you’ve never made jam, this small-batch refrigerator version is a forgiving place to start. No special canning gear is required. It produces that familiar strawberry flavor — sweet at first with a hint of tartness — perfect on toast, biscuits, or in a peanut butter and jelly.
Why You’ll Love This Strawberry Jam
- Three simple ingredients — strawberries, granulated sugar, and lemon juice.
- Classic homemade flavor — ideal for PB&J, biscuits, or shortcake.
- Small batch — about 1½ cups; no canning equipment needed.
- Fresh or frozen berries work, so you can make it anytime.
Ingredients
Notes and substitution ideas are below. Full measurements and the printable recipe are in the recipe card at the end.
- Strawberries — 1 pound, hulled and chopped. Use ripe berries for the best flavor; frozen strawberries work too.
- Granulated sugar — sweetens the jam and helps it thicken.
- Lemon juice — fresh preferred. Acid from the lemon works with the strawberries’ natural pectin to help the jam set and balances sweetness.
- Pinch of salt — optional, but enhances flavor.
Hulling Strawberries
Hulling removes the green top and the small core. Use a small paring knife to cut a shallow cone around the stem, or push a drinking straw from the bottom through the stem to pop it out. No special tools needed for a small batch.
How to Make Strawberry Jam Without Pectin
Follow these steps for stovetop jam. For the printable recipe, see the card below.
Step 1: Combine the chopped strawberries, sugar, lemon juice, and a pinch of salt in a medium saucepan over medium heat.
Step 2: Stir occasionally as the berries soften and release their juices. After a few minutes the pan will look quite wet — that’s normal.
Step 3: Mash the strawberries with a potato masher or the back of a spoon to reach your preferred texture.
Step 4: Bring the mixture to a boil, then reduce heat and simmer for 10–15 minutes, stirring often, until the jam thickens. It’s done when it registers about 210–220°F on a candy thermometer or when the bubbling slows and the surface becomes glossy.
Step 5: Remove from heat and let the jam cool for a few minutes, then spoon into jars. Allow jars to cool completely at room temperature, seal, and refrigerate. The jam will continue to thicken as it cools and sets fully after about 24 hours in the fridge.
Storage
- Refrigerator — keep in an airtight jar for up to 3 weeks.
- Freezer — freeze in a freezer-safe container for up to 3 months. Leave about ½ inch headspace for expansion and thaw overnight in the fridge.
A Quick Note on Canning
This recipe is designed for refrigerator and freezer storage and is not tested for water-bath or pressure canning. For shelf-stable jam, use a tested canning recipe and follow proper sterilization and processing guidelines.
Ways to Use Strawberry Jam
- Spread on bread for a classic PB&J.
- Spoon over warm buttermilk biscuits, pancakes, or waffles.
- Layer between cake layers for a simple strawberry filling.
- Swirl into Greek yogurt, oatmeal, or vanilla ice cream for extra flavor.
Tips for the Best Homemade Strawberry Jam
- Use ripe strawberries. Choose berries that are bright red and slightly soft for richer flavor.
- Chop evenly. Uniform pieces cook down consistently.
- Don’t skip the lemon juice. Strawberries are low in pectin; the acid helps the jam set.
- Stir frequently. Natural sugars can stick and scorch, so keep an eye on the pot.
- For a smooth jam, pulse briefly with an immersion blender after cooking.
Additions and Variations
- Vanilla: Stir in ½ teaspoon vanilla extract after cooking for a dessert-style flavor.
- Lemon zest: Add 1 teaspoon of zest with the sugar for extra brightness.
- Basil: Fold in 1 tablespoon finely chopped fresh basil after cooking for a fresh, surprising note.
- Berry blend: Swap half the strawberries for raspberries or blueberries for a mixed-berry jam.
Recipe
Strawberry Jam Without Pectin
Author: Jaclyn
Equipment
- Medium saucepan, potato masher or spoon, jars for storage
Ingredients
- 1 lb strawberries, hulled and chopped
- ¾ cup (150 g) granulated sugar
- 1 Tbsp lemon juice
- Pinch of salt (optional)
Instructions
- Add the strawberries, sugar, lemon juice, and salt to a medium saucepan over medium heat.
- Stir as the mixture warms and begins to boil. Mash the strawberries to your desired texture.
- Reduce heat and simmer 10–15 minutes, stirring often, until thickened and glossy. It’s done at 210–220°F or when it passes the plate test.
- Remove from heat and let cool a few minutes. Blend briefly with an immersion blender for a smoother texture if desired.
- Spoon into jars leaving about ½ inch headspace. Let cool completely on the counter, then seal and refrigerate. Jam continues to thicken as it cools and sets fully after about 24 hours.
Notes
Plate test: chill a plate in the freezer while the jam cooks. Spoon a small amount onto the cold plate and return to the freezer for one minute. If the jam wrinkles when you push it with your finger, it’s done. If it’s still loose, cook a few minutes longer and test again.
Storage: refrigerate in an airtight jar for up to 3 weeks, or freeze in a freezer-safe container for up to 3 months, leaving space for expansion.
