Why you will like this recipe
- Potatoes get a head start. Roast the halved potatoes first before adding the peppers, onion and sausage.
- Fully cooked chicken sausage added later. The sliced sausage joins the vegetables for the final roast, where its edges can brown.
- One tray with Italian herbs and garlic. Olive oil, Italian seasoning and garlic powder coat the potatoes, peppers and red onion on the same tray.
Substitutions
Use a plant-based fully cooked sausage for a meatless version. Sweet potatoes work but may soften slightly faster.
Ingredient choices and cooking cues
The potatoes receive a head start because they need more time to become tender than the pepper, onion, and sliced cooked sausage need to brown. Keep the potato halves reasonably similar in size; a few unusually large halves can remain firm while the smaller ones are ready. Their cut surfaces provide the broadest contact with the hot tray, helping develop color as the centers soften.
After the other ingredients go in, the single layer matters more than creating a tidy arrangement. Peppers and onions release moisture, and a crowded pile holds that moisture between the pieces. Leave enough room to see parts of the tray rather than stacking everything into a deep mound. If your tray cannot hold the mixture in one layer, that crowding will change the result even when the oven temperature is correct.
Fully cooked chicken sausage contributes seasoning as well as browned edges. Slice it evenly so thin pieces do not become leathery while thick pieces stay pale. During the final check, assess a potato’s center as well as the overall color: a browned sausage slice cannot tell you whether the potatoes are tender. The peppers should have softened and the onion wedges should separate easily while retaining enough shape to serve alongside the potatoes.
Storage and reheating
Refrigerate for up to 4 days. Reheat at 375°F (190°C) until hot.
Serving ideas
Serve the sausage, potatoes and peppers together straight from the tray. The potatoes are already included, so a simple green salad is an optional fresh side.

Frequently asked questions
Can I use raw sausage instead?
Raw sausage is not an equivalent ingredient in this method. The recipe specifically uses fully cooked chicken sausage, and the final roasting stage is arranged around that starting point. A raw product would require its own cooking assessment rather than borrowing the same schedule.
Why are the vegetables soft but not browned?
They may have released more moisture than the tray could evaporate, especially if crowded or piled up. Preserve the single layer and the stated potato head start. Browning depends on exposed surfaces; stirring more often will not solve a pan that is too full.
