Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
In a large bowl, combine the barbecue sauce, Worcestershire sauce, garlic powder, smoked paprika, olive oil, black pepper, and cayenne pepper if using. Mix well to create a flavorful marinade.
Add the sliced sausage to the bowl and toss until each piece is well coated with the sauce mixture.
Spread the coated sausage pieces evenly on the prepared baking sheet in a single layer.
Bake in the preheated oven for 20-25 minutes, stirring halfway through, until the sausage bites are heated through and caramelized.
Remove from the oven and let them cool for a few minutes before serving. Enjoy your BBQ sausage bites warm!
