There’s something about the smell of simmering fruit that folds you into a memory—grandma’s kitchen, a sunny weekend, or the first picnic of summer. If you’ve ever wanted to bottle that warm, fruity comfort, strawberry rhubarb jam is the perfect place to start. It’s bright, a little tart, and forgiving, which makes it an ideal first preserve if you’re new to jam-making.
For a show-stopping dessert, serve a spoonful of jam atop a slice of Samoa Cheesecake to add a bright fruity contrast.
Why this recipe works
This small-batch recipe is built for real life: no giant pots, no special canning gear required (unless you plan to shelf-stable can). The natural pectin in strawberries and the acidity of rhubarb help create a lovely set without added powders if you prefer a looser, spoonable jam. I’ll give tips for both thicker and softer textures so you can pick what fits your pantry and your schedule.

Ingredients
- 3 cups hulled strawberries, roughly chopped (about 1 lb)
- 3 cups chopped rhubarb (about 1/2-inch pieces)
- 2 cups granulated sugar (adjust to taste)
- 2 tablespoons freshly squeezed lemon juice
- 1 teaspoon vanilla extract (optional)
- Pinch of salt
Tip: If your strawberries are very sweet, reduce sugar by 1/2 cup. If they’re underripe, keep the sugar as written to balance the rhubarb’s tartness.
How to Make Strawberry Rhubarb Jam
Time needed: 45 minutes
Plan for about 35–45 minutes from start to finish. Most of that time is simmering while you resist the urge to stir every minute—though a little stirring helps prevent scorching.
- Prep the fruit
Rinse strawberries and hull them; chop into quarters if large. Trim rhubarb and cut into 1/2-inch pieces. Combine fruit in a medium heavy-bottomed saucepan.
- Macreate (optional)
For a brighter jam with less cooking, toss the fruit with sugar and let sit 20–30 minutes to draw out juices. This also helps the strawberries break down more quickly.
- Cook
Place the pan over medium heat, add lemon juice and a pinch of salt. Stir occasionally as the mixture warms; once it reaches a full simmer, reduce heat to medium-low. If you didn’t macerate, cook 20–30 minutes until the fruit is soft and the mixture thickens.
- Test the set
Use the chilled-plate test—drop a spoonful on a small chilled plate and push it; if it wrinkles and doesn’t flood, it’s set. Remember it will thicken more as it cools. If you want a gel-like jam, simmer a bit longer; for spoonable preserves, stop earlier.
- Finish
Stir in vanilla (if using). Skim any foam with a spoon. Ladle into clean jars, leaving 1/4-inch headspace if you plan to refrigerate and eat within a month.
Preserving notes
If you want to can jars for shelf storage, process in a boiling water bath for 10 minutes (adjust for altitude) and ensure proper sealing. Otherwise, store in the refrigerator for 3–4 weeks or freeze for up to 6 months.
Serving ideas
- Spread on buttered toast or warm biscuits.
- Swirl into plain yogurt or layered parfaits.
- Use as a filling for thumbprint cookies, tarts, or a quick jam glaze for hot-buttered scones.
- If you’re gifting jars, include a note suggesting the jam pairs beautifully with a slice of Lemon Cheesecake.
Little tip: A spoonful warmed and poured over vanilla ice cream is a weekday-saver dessert that makes you look like you planned ahead.
Notes: For a smoother jam, mash gently with a potato masher or pulse with an immersion blender for a few seconds. Always use clean tools and jars for longer fridge life.
FAQs
You can reduce sugar, but keep in mind sugar helps with texture and preservation. For a low-sugar version, consider using a powdered pectin designed for low-sugar preserves or rely on refrigeration and eat it quickly.
Runny jam usually means it hasn’t cooked long enough or the proportion of fruit to liquid is high. Try cooking a bit longer, testing often, or increase the fruit slightly. If you don’t want to cook more, stir in a small amount of low-sugar pectin per the package directions.
Yes—raspberries or peaches can work in place of strawberries for interesting flavor twists. Keep the rhubarb ratio similar so you maintain that tangy backbone.
Conclusion
Making strawberry rhubarb jam is one of those small, delicious acts that rewards you for slow, simple work. You’ll end up with jars of bright, ruby jam that feel homemade in every sense: imperfect, fragrant, and intensely comforting. Whether you’re gifting a jar or saving it for rainy mornings, this recipe is a reliable go-to.
Now grab a clean jar, a loaf of crusty bread, and a spoon—your kitchen is about to smell like summer. If you want a cozy pairing, slice warm bread like the Apple Crisp Sourdough Loaf and spread the jam while the loaf is still warm.

- Add lemon juice and a pinch of salt. Heat over medium until simmering, then reduce to medium-low. Stir occasionally and simmer until fruit breaks down and mixture thickens, about 20–30 minutes.
- Use the chilled-plate test to check the set. Stir in vanilla if using, skim any foam, and ladle into clean jars leaving 1/4-inch headspace. Refrigerate for short-term storage or process in a boiling water bath if canning for shelf storage.
Notes
- For a firmer set, cook a little longer or use low-sugar pectin per package directions.
