Ingredients
For the Sheet Pan
- 1 1/2 pounds baby potatoes, halved
- 2 tablespoons olive oil, divided
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon kosher salt, divided
- 1/2 teaspoon black pepper
- 14 ounces fully cooked kielbasa, sliced 1/2 inch thick
- 1 red bell pepper, cut into chunks
- 1 yellow bell pepper, cut into chunks
- 1 large red onion, cut into wedges
- 2 tablespoons chopped parsley
Substitutions
- Chicken sausage can replace kielbasa and should reach 165°F.
- Yukon Gold chunks can replace baby potatoes.
- Cajun seasoning can replace paprika and garlic powder.
Instructions
Step 1: Heat the Oven
Preheat to 425°F and place a large sheet pan in the oven for 5 minutes.
Step 2: Start the Potatoes
Toss potatoes with half the oil, paprika, garlic powder, half the salt, and pepper. Arrange cut-side down and roast 15 minutes.

Step 3: Prepare the Rest
Toss kielbasa, peppers, and onion with remaining oil and salt.

Step 4: Add to the Pan
Turn potatoes, add sausage and vegetables in a single layer, and return to the oven.

Step 5: Roast
Cook 18 to 20 minutes, stirring once, until potatoes are tender and sausage and peppers are browned.

Step 6: Heat Safely
Confirm reheated kielbasa is steaming and the dish reaches 165°F in the center.
Step 7: Finish
Sprinkle with parsley and serve hot directly from the pan.

Why the Potatoes Start First
The potatoes need more oven time than the already-cooked kielbasa and the peppers. Giving them a 15-minute head start on the hot sheet pan builds browned cut sides before the remaining ingredients are added, so the sausage does not dry out while you wait for the potatoes to become tender.
How to Store Leftovers
Refrigerate within 2 hours and use within 4 days in an airtight container.
Freeze cooked portions for up to 2 months; peppers may soften slightly.
How to Reheat
Spread on a sheet pan and reheat at 400°F until 165°F and edges re-crisp. Add fresh parsley afterward.
