directions

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a skillet over medium heat, melt the butter and sauté the onions until deeply caramelized, about 20-25 minutes.

Add garlic and thyme, cooking for another minute, then deglaze with a splash of beef broth and cook until evaporated. Let cool.

In a bowl, mix the sausage, cooled onion mixture, Dijon mustard, grated cheese, salt, and pepper.

Cut puff pastry sheets into rectangles and spoon sausage filling along one edge of each rectangle.

Roll the pastry over the filling and seal the edge by pressing with a fork. Cut into desired lengths.

Place rolls seam-side down on the baking sheet, score the tops lightly, and brush with egg wash.

Bake for 20-25 minutes or until golden and cooked through.

Allow to cool slightly before serving.
