. Heat the Oven
Set your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray to prevent sticking.
Slice the Sausage
Cut the smoked sausage into bite-sized rounds, about 1 inch thick.
Mix Everything Together
Add the sausage pieces into the prepared baking dish. Pour in the BBQ sauce, sprinkle the brown sugar, and add the Dijon mustard. Stir everything until the sausage is evenly coated in the sauce.
Bake Until Sticky & Caramelized
Place the dish in the oven and bake for about 45 minutes. The sauce should thicken, darken slightly, and become nice and bubbly.
Tip: Give it a quick stir once or twice during baking so every piece stays coated and flavorful.
Serve
Let cool slightly, then serve warm. Stick in toothpicks for easy grabbing—perfect for parties or casual snacking.
