First, I preheated the oven to 425°F (about 220°C) to get a good roast going. Then I spread the cubed sweet potatoes, sliced onion, and chopped garlic onto the baking sheet. Drizzled the olive oil and sprinkled my seasoning on top — tossed everything so each piece was coated.
I placed the tray in the oven and roasted for about 20 minutes. After that, I removed the sheet, stirred the veggies, spread them out again to avoid crowding, then returned them for another 15 minutes. This helps caramelize the sweet potatoes and give the onion and garlic those golden‑crispy edges.
I then added the sausage slices, arranging them so they touched the hot pan (cut side down helps). Roasted everything together for another 10 minutes until the sausage browned and the potatoes were tender. At that point I removed the tray, let it cool slightly, then drizzled a honey‑garlic sauce (my own twist) if desired and served.
