Preheat Oven & Prep Dish: Preheat your oven to 400°F (200°C). Place the 8 sausages in a rectangular aluminum foil container or a baking dish.
Make the Glaze: In a small bowl, whisk together the ¼ cup honey, 3 tablespoons soy sauce, 2 tablespoons olive oil, 4 cloves of minced garlic, and ½ teaspoon black pepper.
Bake the Sausages: Pour the honey garlic mixture over the sausages, making sure they are well coated. Scatter the 1 thinly sliced medium onion among the sausages. Bake in the preheated oven for 25-30 minutes, turning the sausages halfway through, until they are golden brown and cooked through.
Serve: Remove the dish from the oven and let the sausages rest for a few minutes. Garnish with the optional 1 tablespoon of chopped fresh parsley and serve.
Enjoy these simple yet flavorful sausages!
