Preheat Oven: Preheat your oven to 200°C (400°F). For easy cleanup, line a large baking tray with parchment paper or heavy-duty aluminum foil.

Mix the Glaze: In a small mixing bowl, combine the olive oil, soy sauce, honey, smoked paprika, garlic powder, and black pepper. Whisk vigorously until the ingredients are completely smooth and well mixed.

Prep the Onions: Spread the thickly sliced yellow onions evenly across the prepared baking tray to create a thick, flavorful bed for the meat.

Arrange & Glaze: Arrange the smoked sausages directly over the layer of onions. Using a pastry brush, coat the sausages generously with the prepared glaze, making sure to reserve a small amount of the glaze for the very end.

Bake: Place the tray in the preheated oven and bake for 35 to 40 minutes. You must turn the sausages halfway through the cooking time to ensure they brown and caramelize evenly on all sides.

Final Glaze: Remove the tray from the oven once the sausages are sticky and the onions are jammy. Immediately brush the hot sausages with the remaining reserved glaze.

Rest & Serve: Let the entire dish rest on the pan for 5 minutes before serving. Serve the glazed sausages and caramelized onions warm over rice or mashed potatoes!
