Preparation and Cooking Overview

Simmer fresh or frozen berries with sweetener, lemon juice, and water over medium heat for 10–12 minutes, stirring occasionally until the berries break down. Mash for a smoother texture if desired, then stir in chia seeds and let sit for 5 minutes to thicken. Once cooled, transfer to a jar and store in the fridge.

Chef's note

For the best flavor, use a mix of berries like strawberries, raspberries, blackberries, or blueberries. Adjust sweetness to taste by adding more erythritol or a few drops of liquid stevia. For a smoother jam, blend the mixture before adding chia seeds. You can also swap chia seeds for gelatin if you prefer a thicker, jelly-like texture.

  • ¼ cup erythritol
  • 1 tablespoon lemon juice
  • 2 tablespoons chia seeds

Additional Ingredients

Want to enhance your keto-friendly jam? Try adding:

  • Vanilla Extract: A touch of vanilla enhances the natural sweetness of the berries and adds warmth to the jam’s flavor.

  • Orange Zest: The bright citrusy notes balance the sweetness and add a refreshing twist to the jam.

Chef's pro tip

Overcooking the berries can result in a jam that’s too thick and loses its fresh fruit flavor. To prevent this, simmer just until the berries break down and release their juices, about 10–12 minutes. If the consistency becomes too thick, stir in a little extra water or lemon juice to adjust the texture without compromising flavor.

How to Serve Keto Jam

  • Keto Bread or Toast: Spread it over a slice of toasted keto bread or almond flour biscuits for a quick, low-carb breakfast.
  • Yogurt Topping: Swirl it into unsweetened Greek yogurt or coconut yogurt for a fruity, naturally sweetened snack.
  • Cheese Pairing: Serve alongside a cheese platter with brie, cream cheese, or cheddar for a delicious sweet-savory contrast.
  • Keto Pancakes & Waffles: Drizzle over keto-friendly pancakes or chaffles instead of syrup for a fruity twist.
  • Fat Bomb Filling: Use it as a filling for keto fat bombs or thumbprint cookies to add a burst of berry flavor.

How to Make It Healthier

  • Reduce the sweetener if your berries are naturally sweet.
  • Add extra fiber by increasing chia seeds to 3 tablespoons.
  • Use organic, fresh berries for fewer additives.

Time-Saving Tips

  • Use frozen berries to skip washing and hulling.
  • Make a double batch and freeze extras for future use.

What Can I Prepare Ahead of Time?

  • Pre-wash and hull berries and store them in the fridge.

Storage Instructions

  • Refrigerator: Store in an airtight container for up to 1 week.
  • Freezer: Freeze for up to 3 months (leave space in the jar for expansion).

Note: Freezing may change the texture, making it slightly looser when thawed.
