Preheat oven to 350°F (175°C) and line a baking dish with foil. This helps prevent sticking and makes cleanup easier.
Remove casing from the salami and place it on a cutting board. Make shallow ¼-inch slices across the top, stopping about ¾ deep so it stays connected.
Place scored salami into the prepared baking dish. Gently fan the slices so glaze can seep inside.
In a bowl, mix apricot preserves, Dijon mustard, brown sugar, and barbecue sauce until smooth and glossy.
Brush half the glaze generously over and between the salami slices. Make sure it fully coats the surface for caramelization.
Bake for 30–35 minutes until edges begin to curl and glaze becomes bubbly. You will see rendered fat in the pan.
Brush remaining glaze over the top and return to oven for 10–15 minutes. The surface should darken slightly and look sticky.
Optional: Broil for 1–2 minutes for extra crisp edges, watching closely to prevent burning.
Rest for 5 minutes before slicing into bite-sized pieces. Serve warm with crackers or toothpicks.
