Homemade Blueberry Preserves are sweet, flavorful and so easy to make. It's the perfect topping for scones, biscuits and waffles. With a handful of blueberries and a few pantry staples (no pectin required!), you’ll have delicious preserves in just 30 minutes.
Since creating my sourdough starter and learning how to make sourdough bread at home, I’ve been passionate about making everything from scratch. In the last 4 years, I’ve learned how to make fresh tomato sauce, fresh fruit syrups and even homemade cultured butter.
Out of everything, I probably make these preserves the most. I love that I can make it at the last minute and have a delicious topping for my breakfast even if I don’t have any store bought jam or jelly.
No pectin needed!
Blueberries are naturally high in pectin, a starch that is used to thicken jams and jellies. These preserves don’t need to be as thick as jam, so we won’t be using it for this recipe. If I want a thicker consistency, I use cornstarch since I always have it in my pantry. If using, dissolve the cornstarch in water first and make sure your blueberry mixture is simmering or you’ll end up with clumps of cornstarch in your preserves.
This recipe makes a small batch, about 8 oz, so I don’t usually bother canning. This is enough to have for breakfast with a little bit leftover to enjoy for up to a week. You will have to refrigerate any leftovers.
What you need
- Fresh or frozen blueberries
- Lemon juice
- Cornstarch (optional)
- Combine blueberries, sugar, lemon juice and water in a small saucepan
- Bring mixture to a boil, turn down the heat to medium low and let simmer until blueberries have broken down
- Dissolve cornstarch in a little bit of water and stir it into the preserves
- Continue to simmer until preserves reach your desired consistency
What is the difference between blueberry jam and blueberry preserve?
Preserves have larger pieces of fruit while jam is made with mashed fruit and is usually thicker.
Since these preserves are not canned they only last about a week and need to be refrigerated. To preserve the shelf life, you'd have to can your preserves.
If your preserves are too watery, just let it simmer at a higher temperature for a few minutes longer. If it's still too thin, add a little bit more dissolved cornstarch.

These recipes were developed and tested using grams for precise measurements. To increase your chances of success, I recommend investing in a kitchen scale. I've included rough volume estimates (in tablespoons and cups), but they might not be totally accurate.
Remember all ovens are unique, these recipes were tested in my oven which runs cooler than others. You might need to lower the temperature if your bake appears to be browning too quickly. Monitor your bake closely and make adjustments if needed.
