This Sheet Pan Sausage and Potatoes recipe, with sweet onions and peas, roasts everything on one pan for a family-friendly, hands-off dinner with minimal cleanup.

This Sheet Pan Sausage and Potato dinner is one of the few dishes that have been on repeat in my home, on a monthly basis, since my kids were born. Which says a lot about this dish, because I am a recipe developer and don't often repeat dishes unless I'm testing them, or they're a real family favorite. And that last part is where this recipe lands. This dinner isn't the fastest: it takes about an hour. But it's easy: one pan, five main ingredients, and the oven is doing most of the work while I do something else.
Potatoes, onion, and garlic roast first, then sausages are added, and their drippings settle into the potatoes and help them continue to crisp up. The peas go in for the last few minutes, added at the very end, so they stay bright and perfectly cooked. This recipe doesn't need much from you beyond a cutting board and a timer, which is one of the other reasons it's stayed in rotation in my house all these years.
How to Make It
Another great aspect of this recipe is that it's so flexible: any potatoes work if cut into even pieces (I'm pretty sure I've used all the different varieties over the years), the spices can be adjusted to taste (a premixed blend works great here), any sausage works in place of italian (raw or fully cooked), and finally, the peas can be swapped for another frozen or fresh vegetable (I often put a "frozen veggie" mix in it, just make sure the pieces are small so they cook quickly). You'll need a half sheet pan, or a 13x18-inch rimmed baking sheet, to make it.
The most important detail about making this dish is setting your timer! The recipe is largely hands-off cooking, but you do have to stagger when you add the different elements to the sheet pan so that they all cook appropriately.

Step 1: Toss together the potatoes, onion, garlic, olive oil, and salt, then spread everything into an even layer.

Step 2: Bake until the onions are translucent. Stir the potatoes and onions to ensure even cooking. Add sausages.

Step 3: Return the sheet pan to the oven and bake until the sausages are fully cooked through.

Step 4: Move the sausages to one side of the sheet pan, stir the peas into the potatoes on the other, and return the pan to the oven until the peas are bright green but cooked through, about 5 minutes. Slice the sausage, if desired and serve!
Storing Leftovers
To store, cool any leftovers to room temperature. Then, transfer them to an airtight container and refrigerate, typically for 3-5 days. I love storing leftovers in these glass containers, as they serve as both storage and a vessel to reheat in. To reheat, warm them in the toaster oven or microwave.

Description
This sheet pan dinner is mostly hands-off, which is exactly why it's been on repeat in my house for over a decade. Potatoes, onion, and garlic roast first, then Italian sausage joins the pan, and frozen peas go in last to round the dish out. Set a timer, and the oven does most of the work.
Ingredients
- 2-½ pounds yellow or red potatoes, scrubbed or peeled and sliced into ½-inch pieces
- 1 large onion, thinly sliced
- 4 cloves garlic, minced
- 4 tablespoons olive oil
- 1 teaspoon dried oregano
- 1 teaspoon coarse kosher salt
- 1 teaspoon garlic powder
- 6-8 Italian sausages
- 2 cups frozen peas
Instructions
- Preheat the oven to 400°F and place an oven rack in the lower part of the oven.
- On a rimmed sheet pan, toss together the potatoes, onion, garlic, olive oil, oregano, garlic powder, and salt.
- Bake on the lower rack until the onions are translucent, about 25 minutes.
- Remove the sheet pan from the oven and stir the onions and potatoes, using a spatula to release any stuck-on potatoes. Arrange the sausages on top of the potatoes.
- Return the sheet pan to the oven and bake until the sausages are fully cooked through, about 25 minutes.
- Move the sausages to one side of the sheet pan, and move the potatoes to the other. Add the peas to the potatoes and toss to combine.
- Return the sheet pan to the oven one last time and cook until the peas are bright green but cooked through, about 5 minutes.
- Divide the sausages, potatoes, and peas onto plates and serve immediately.
Notes
This recipe was tested using Diamond Crystal coarse kosher salt. If you use Morton's kosher salt or fine salt, decrease the volume by half.
The recipe calls for yellow potatoes, but truly any type of potato will work here. Just make sure they're cut into pieces that are about the same size so they cook at the same time.
The spices can be adjusted to anything you like. I typically use more Italian dried herbs, but I've used a lot of different premixed blends too.
Any sausage works in place of Italian, raw or fully cooked.
The peas can be swapped for another frozen or fresh vegetable, such as a small frozen veggie blend. Just don't use any large veggies (like cauliflower or broccoli) as they won't cook in the amount of time the recipe calls for.

Hi I made this meal and it brings back memories of my grandfather making this. The only thing different is he also added green peppers. I would like to make this again with green pepper. My question is when would you think I should add the peppers if I try it! Thank you for a wonderful recipe

So happy you loved it and it made you think of your family. I would suggest adding them with the sausage, or maybe slightly after?

Excellent!
I had no idea you could use peas in a sheet pan roast!
Delicious! Brings a lovely fresh green to the nicely caramelized potato onion garlic mixture.
I used shallots and celery but this will work with any vegetables.
