Prepare the Sausage:

• Slice the 2-3 lbs sausage into ½-inch rounds. This ensures even cooking and allows the sauce to coat each piece thoroughly, creating a consistent texture.

Combine the Sauce and Sausage:

• Combine the 2 cups BBQ sauce and 2 teaspoon liquid smoke (if using) in a large bowl. This creates the flavorful marinade, ensuring a harmonious blend of flavors.
• Add the sliced sausage to the bowl and toss to combine. Ensure the sausage is evenly coated in the sauce, creating a rich and flavorful coating.

Transfer to Baking Dish and Add Brown Sugar:

• Transfer the BBQ sausage to a 9×13 baking dish. This provides enough space for the sausage to cook evenly, preventing overcrowding.
• Sprinkle the ¼ cup light brown sugar over the top of the sausage. This helps caramelize the sauce and adds sweetness, creating a sticky, sweet glaze.

Bake the Sausage:

• Bake at 350°F (175°C/Gas Mark 4) for 40-45 minutes or until bubbling and sticky and the sauce has caramelized. The time may vary depending on the type of sausage and your oven. Use a meat thermometer to ensure the sausage is cooked through.
• Note: If using frozen sliced sausage, add 10 minutes to the cooking time. Ensure the sausage is cooked through and the sauce is bubbling, preventing undercooking.

Serve:

• Remove from the oven and serve immediately. This ensures the best flavor and texture, maximizing the enjoyment of the dish.
