Line a baking sheet with parchment paper and set aside.
In a microwave-safe bowl, combine the semi-sweet chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.
Dip each strawberry half into the melted chocolate, allowing any excess chocolate to drip off. Place the chocolate-covered strawberries on the prepared baking sheet.
If desired, sprinkle a small pinch of sea salt on top of each chocolate-covered strawberry before the chocolate sets.
Once all strawberries are coated, place the baking sheet in the freezer for at least 30 minutes or until the chocolate is firm.
Serve immediately or store in an airtight container in the freezer for up to one month.
