Why You Will Love This Recipe

Strawberries: While I love making this jam with fresh strawberries you can also substitute frozen strawberries when fresh strawberries aren't in season.
To use frozen strawberries, thaw and drain off the excess moisture before roasting the strawberries.
Granulated White Sugar: Sugar helps the jam to set and preserves the color. Do not change the amount of sugar or you could end up with runny jam.
Balsamic Vinegar: The acid in the vinegar helps to brighten the flavor of the strawberries.
Salt: I add at least a pinch of salt to all of my recipes. Salt complements and intensifies the other flavors. For all of my recipes, I use Morton Kosher Salt which is saltier than Diamond Crystal Kosher Salt. If you are using Diamond Crystal Kosher Salt you will want to double the amount of salt you add.
See the recipe card for quantities.
Preheat the oven to 350 degrees Fahrenheit.
Toss the strawberries, sugar, and vanilla together in a glass baking dish. I used this 2-quart Pyrex dish. Spread the mixture out so the strawberries are in a single layer.
Roast in the oven stirring every 30 minutes until the jam reduces and the juice almost completely evaporates. Approximately 1 ½ to 2 hours depending upon the water content of the strawberries.
Watch closely toward the end of the cooking time. As the sugar concentrates the jam will burn more easily.
Remove from oven and let cool to room temperature. Once completely cool, mash to break up larger chunks of strawberry. A potato masher is a great tool for this.
Store in an airtight container in the refrigerator.
