Roasted Sausage, Potatoes and Peas

This sheet pan sausage dinner is one of the few dishes that have been on repeat in my home on a monthly basis since my kids were born. This dinner isn't the fastest to get on the table (it takes about an hour) but as sheet pan meals generally are, it's a hands-off cooking meal and really just requires you to set a timer and add some ingredients to the sheet pan.

All the elements of this dish really come together well, between the savory roasted potatoes, the sweet caramelized onion and peas, and those Italian sausages that cook nestled on top of everything else, infusing the whole dish with the flavorful drippings.

So let's get to making it! The text below offers some tips for making it, or you can scroll down to the bottom for the complete recipe.

Ingredients and Substitutions

Here is a brief overview of the ingredients needed for this recipe. The full recipe with quantities is listed below this text in the recipe card. If substitutions are available for this recipe, they'll be listed here. If you don't see a substitution you are looking for, please leave a comment below.

2-3" small yellow or red potatoes (if you can't find these baby potatoes use the same weight of yukon gold potatoes or russett potatoes, diced into 1-½”-2” pieces.)
onion + garlic
olive oil
spices: oregano, basil, salt, pepper, garlic powder (you can play around with these and make it your own)
italian sausages (you can really substitute any sausage here, but specifically this calls for raw italian sausage links)
frozen peas (the peas are a great choice here, but you can use other frozen or fresh veggies such as green beans)

Let's Talk Sheet Pans

The beauty of this recipe is that you really just need a sheet pan to make it happen. And when I say sheet pan, I'm referred to what is referred to as a half sheet pan, or a 13" by 18" rimmed baking sheet. Here is my favorite sheet pan I recommend (affiliate link).

How to Make It

The most important detail about making this dish is making sure to set your timer! While this dish is largely hands-off cooking, you do have to stagger when you add the different elements to the sheet pan that way they all cook at appropriately. Setting the timer ensures you don't forget to add on the sausage and the peas.

This is an overview of the steps and some explanation behind why the recipe calls for each of them. If you are looking for the full recipe, keep scrolling!

How to Store Leftovers and Reheat

These roasted sausage and potatoes make great lunch the next day. This dish will keep well for 2-3 days in the refrigerator.

To reheat you can heat it in an oven-safe container. I love using these (affiliate link) Glass Pyrex Containers because they double as storage and baking dishes. Or, you can reheat briefly in the microwave until warmed through.
