3 tablespoons olive oil
-
1 tablespoon butter (optional but adds richness)
-
1 teaspoon salt

🔥 Step-by-Step Instructions
1️⃣ Preheat & Prepare
-
Preheat oven to 400°F (200°C).
-
Line a rimmed baking sheet with foil (for easy cleanup).
-
Lightly grease with olive oil or cooking spray.
2️⃣ Prepare the Onions
In a large bowl, toss sliced onions with:
-
Olive oil
-
Salt
-
Pepper
-
Garlic powder
-
Thyme
-
Brown sugar (if using)
Spread onions evenly on the baking sheet.
3️⃣ Add the Sausages
-
Place sausages directly on top of the onions.
-
Leave a little space between them for even browning.
-
Do NOT pierce sausages (keeps them juicy).
4️⃣ Roast
Bake for 25 minutes, then:
-
Flip sausages.
-
Stir onions to prevent burning.
Return to oven for another 10–20 minutes, until:
-
Sausages are browned and caramelized.
-
Internal temperature reaches 160°F (71°C) for pork sausage.
-
Onions are soft and golden.
5️⃣ Optional Flavor Boost
For deeper caramelization:
-
Drizzle balsamic vinegar over onions during the last 10 minutes.
-
Broil for 2–3 minutes at the end for extra browning (watch carefully).
🍽️ Serve With

Crusty bread or hoagie rolls

Mashed potatoes
