  • 2 cups marionberries (fresh frozen)
  • 2 tablespoons honey
  • 1 tablespoon orange juice (freshly squeezed)
  • 1 tablespoons chia seeds


  • Put the frozen marionberries (blackberries) in a medium saucepan over medium heat on the stovetop. Heat the fruit for 5-10 minutes, allowing it to break down. Give it a stir occasionally.
  • While the berries are heating, squeeze the juice from half of an orange. You'll need one tablespoon of juice for this recipe.
  • After cooking the marionberries, take them off the heat. Mash the berries to the desired consistency with a potato masher or a fork. I like to make my jam pretty smooth; there will still be plenty of texture from the seeds.
  • After mashing, stir in the honey, fresh orange juice, and chia seeds. Let your jam stand until it has cooled and thickened. Then put the jam into a glass jar (or jars) and refrigerate it overnight.
  • In the morning, you'll be ready to use your fresh Oregon marionberry jam! Any jam that you will not use in 3-4 days should be stored in a freezer-safe container in the freezer.
  • Hot tip! If the marionberry jam isn't thickened enough after refrigerating overnight, add more chia seeds and refrigerate again for 8-12 hours.


This is a level 1 recipe (may help support fat loss). Berries are a low-calorie food that fit most of the dietary patterns that are used for weight loss. (This includes low carb and keto diets.) You can use this low sugar marionberry jam as an easy way to add fruit to a variety of dishes.
How well this food ultimately fits if you are looking to lose weight depends on what it is served with. Try putting it on high-protein, low-fat Greek yogurt for a lower calorie, satiating dish.
For a higher energy (i.e., higher-calorie) meal, you could serve this jam in a sandwich that is thickly spread with nut butter. Use whole grain bread for a higher fiber meal. I have more ideas for using marionberry jam in different ways in this article.
If you are accustomed to foods being heavily sweetened, this low sugar jam may not be sweet enough for you. In that case, you could add your favorite non-nutritive sweetener, maple syrup or more honey. Please keep in mind that using more sweetener will alter the nutritional information for the recipe.
Added sugars, including natural sweeteners like honey and maple syrup, pack a lot of calories into a small volume. IMVHO, it is better to skip the additional sweeteners and make a sugar free marionberry jam. I have made this marionberry jam without honey and enjoyed it, but I know that’s not for everyone.
Nutrition information is for one serving of the recipe. (The total yield is 1.5-2 cups of jam.)
