Ingredients
  

Slow Cooker Strawberry Butter Ingredients
  • 4 lbs Strawberries fresh or frozen, hulled and quartered if fresh, thawed if frozen
  • 1 1/2 cups Granulated Sugar adjust to taste based on strawberry sweetness
  • 2 tbsp Lemon Juice freshly squeezed, enhances flavor and aids setting
  • 1/2 tsp Ground Cinnamon for warm spice notes
  • 1 tsp Vanilla Extract added at the end for best flavor

Equipment

  • Slow Cooker (6-quart or larger)
  • Potato Masher or Fork
  • Heatproof Spatula
  • Sterilized jars (half-pint or pint)
  • Lids and Bands
  • Ladle
  • Funnel (optional, for jarring)

Method
 

Prepare the Strawberries
  1. If using fresh strawberries, hull them and cut larger berries into quarters. If using frozen strawberries, ensure they are fully thawed and drain any excess liquid.
Combine and Slow Cook
  1. In a 6-quart (or larger) slow cooker, combine the prepared strawberries, granulated sugar, lemon juice, and ground cinnamon. Stir well to ensure all ingredients are evenly distributed and the strawberries are coated.
  2. Cover the slow cooker with its lid and cook on the LOW setting for 4 to 5 hours. During this time, the strawberries will soften considerably and release a good amount of liquid.
Mash and Thicken
  1. After 4-5 hours of cooking on LOW, remove the lid. Use a potato masher or a sturdy fork to mash the softened strawberries directly in the slow cooker until they reach a smooth, jam-like consistency. For an exceptionally smooth butter, carefully transfer the mixture to a blender or food processor and blend until completely smooth, then return it to the slow cooker.
  2. Leave the lid slightly ajar (you can prop it open with a wooden spoon) and change the slow cooker setting to HIGH. Continue to cook for another 1 to 2 hours, stirring occasionally (every 20-30 minutes) to prevent sticking and ensure even reduction. The strawberry butter will thicken and darken as moisture evaporates.
  3. During the final 30 minutes of the thickening process (while on HIGH), stir in the vanilla extract. This ensures the vanilla flavor remains prominent.
Jar and Store
  1. Once the strawberry butter has reached your desired thickness, carefully ladle the hot butter into clean, sterilized half-pint or pint jars, leaving approximately 1/4 inch headspace. Wipe the rims of the jars clean with a damp cloth, then apply the lids and screw bands finger-tight.
  2. Allow the jars to cool completely on your kitchen counter. As they cool, you may hear a 'pop' sound indicating a proper seal. Once fully cooled, label the jars. Refrigerate for immediate use, where it will last for up to 3-4 weeks. For longer, shelf-stable storage, follow proper boiling water bath canning procedures (e.g., process half-pints for 10 minutes at a full rolling boil; refer to USDA guidelines for safety).

Notes

For a less sweet butter, you can reduce the sugar by up to 1/2 cup, tasting and adjusting as it cooks. If using very sweet ripe strawberries, you might need less sugar. This strawberry butter makes a wonderful homemade gift. Store leftover butter in the refrigerator for up to 3-4 weeks. For shelf-stable storage, follow proper canning procedures, ensuring jars are clean and sterilized, and processing in a boiling water bath for 10 minutes.
