Step 1

Preheat the oven to 425°F.

Step 2

Place the sausage, peppers, onions, and potatoes in a 13x9-inch metal roasting pan, cake pan, or glass baking dish (not a sheet pan).

Step 3

Add the olive oil, Italian seasoning, garlic powder, salt, and pepper; stir to coat the sausage and vegetables with the oil and seasonings.

Step 4

Bake for 50 to 60 minutes or until the potatoes are tender and the sausage is cooked through (minimum internal temperature of 160°F), stirring once about halfway through the cooking time to ensure everything cooks evenly, and turning the sausage pieces over so they get golden brown on both sides.

Step 5

Taste and adjust seasoning if needed. Serve immediately.
