This sheet pan sausage and potatoes dinner is an easy, oven roasted meal with crisp golden potatoes, sweet browned onions, and smoky sausage, all cooked on one pan. It takes 10 minutes of prep, uses six pantry ingredients, and leaves you with almost nothing to wash.
The recipe serves 4 and is flexible, so it works for a busy weeknight, a casual dinner with friends, or a make-ahead meal for the week. The oven does the work while you set the table, and the pan drippings flavor the potatoes as they roast.

Why This Works
Smoked sausage is already cooked, so it only needs to heat through and brown at the edges. That means it can share a pan with raw potatoes without any extra steps, and its rendered fat seasons everything around it as it roasts.
Cutting the potatoes into small, even pieces is the key. About 3/4-inch dice cook through in the time it takes the sausage to brown, and the cut sides touch the hot pan and turn crisp. Tossing the vegetables with olive oil before roasting helps the outsides brown instead of drying out.
Onions roast sweet and soft at the high heat of 400 degrees F, with browned tips that add a caramelized flavor. A little garlic powder and paprika bring warmth and color without any extra chopping.
Ingredients
- 1 pound smoked sausage, sliced into 1/2-inch rounds
- 2 pounds potatoes, diced into 3/4-inch pieces
- 1 large onion, sliced
- 2 tablespoons olive oil
- 1/2 teaspoon salt, plus more to taste
- Black pepper, to taste
- 1 teaspoon garlic powder (optional)
- 1 teaspoon paprika (optional)
How to Make Sheet Pan Sausage and Potatoes
1. Heat the oven
Preheat the oven to 400 degrees F (200 degrees C). Place a large rimmed baking sheet in the oven while it heats if you want extra crisp potatoes.
2. Prep the ingredients
Dice the potatoes into even pieces of about 3/4 inch, slice the onion, and slice the sausage into rounds. Even sizes mean even cooking.
3. Toss everything together
In a large bowl, combine the potatoes, onion, and sausage. Drizzle with the olive oil and season with the salt, pepper, garlic powder, and paprika. Toss until everything is coated evenly.
4. Spread on the pan
Spread the mixture in a single layer on the baking sheet. If the pan looks crowded, split it between two sheets, because overcrowded potatoes steam instead of roasting.
5. Roast and stir
Roast for 30 to 35 minutes, stirring halfway through, until the potatoes are golden and tender when pierced with a fork. Larger pieces may need a few extra minutes.
6. Serve
Serve warm, straight from the pan. Taste and add a little more salt if needed, since saltiness varies by sausage.
How to Serve
This dish is filling on its own, but a vegetable side makes it a complete meal. Try it with green beans with a mountain of panko for crunch, or add a pan of roasted vegetables alongside it in the same oven. A cool, tangy creamy coleslaw balances the smoky sausage, and air fryer breaded broccoli is a fun side for kids and adults.
For a final touch, squeeze a little lemon over the pan or sprinkle on chopped parsley just before serving. Mustard on the side also goes well with smoked sausage.
How to Store and Reheat
Let the pan cool for a few minutes, then refrigerate leftovers in an airtight container within two hours of cooking. Eat them within three to four days.
Reheat on a baking sheet in a 400 degree F oven for about 10 minutes, or in a hot skillet, so the potatoes crisp up again. A microwave works for a quick lunch but softens the potatoes. Leftovers should be reheated to 165 degrees F before eating.
Tips and Variations
Follow standard leftover rules. The USDA Food Safety and Inspection Service leftovers guidance recommends storing food in shallow containers, refrigerating promptly, and reheating to 165 degrees F.
Cut potatoes into even pieces and do not crowd the pan. Those two steps matter more than any seasoning for getting crisp edges. Leaving the potato skins on adds texture and saves prep time, as long as you scrub them well.
To change the flavor, toss in sliced bell peppers during the last 15 minutes, use Italian seasoning instead of paprika, or finish with grated Parmesan. Kielbasa, turkey sausage, or andouille can replace the smoked sausage. Sweet potatoes also work, though they cook slightly faster.
FAQ
Do I need to cook the sausage first?
No. Smoked sausage is fully cooked, so it only needs to heat through and brown. Add it to the pan with the potatoes.
Why are my potatoes not crispy?
The pan is usually too crowded, or the potatoes were cut too large. Use two sheets, keep the dice small and even, and let the oven reach full temperature first.
What kind of potatoes work best?
Yukon gold and red potatoes hold their shape and get creamy inside. Russets crisp nicely but can break apart more easily.
Can I make this in an air fryer?
Yes, in batches. Cook at 400 degrees F, shaking the basket halfway through, until the potatoes are golden and tender.
Can I prep this ahead?
You can slice the sausage and onion a day ahead. Diced potatoes can sit in cold water in the refrigerator for a few hours, but drain and dry them well before tossing with oil so they roast instead of steam.
