Preheat the Oven: Set your oven to 350°F (175°C) and prepare a baking sheet with parchment paper.

Prepare the Dough: Unroll the crescent roll dough, pressing the perforations to seal and form a continuous sheet. Arrange the dough into a large rectangle on the prepared baking sheet.

Add the Filling: Evenly spread the boudin sausage (with casings removed) along the center of the dough. Sprinkle the shredded pepper jack cheese over the boudin.

Form the King Cake: Gently roll the dough around the filling, sealing the edges to encase the boudin and cheese. Shape the filled dough into an oval or ring, resembling a traditional king cake.

Apply Egg Wash: Brush the beaten egg over the surface of the dough to enhance browning. Sprinkle with flaky salt to taste.

Bake: Place the assembled king cake in the preheated oven and bake for 25-30 minutes, or until golden brown.

Prepare the Glaze: While the king cake is baking, heat the pepper jelly in a saucepan over low heat until it becomes thin and pourable. If necessary, add a teaspoon of water to achieve the desired consistency.

Add Toppings: Once the king cake is baked, remove it from the oven and let it cool slightly. Drizzle the warm pepper jelly glaze over the top, then sprinkle with crumbled bacon, sliced green onions, and crushed pork rinds, if using.

Serve: Slice and serve the Boudin King Cake warm.
