Roasted Sausage, Potatoes and Peppers

Italian sausage, potatoes, bell peppers and onions oven-roasted with fresh rosemary in an olive oil and parmesan cheese dressing.

Yes, I’m still on a roasting binge. No, the end is not near.

One of the many things I love about roasting is the oven does most of the work! A few minutes of prep combined with some flavorful seasonings and dinner is as good as done. It will seem as if you slaved over the stove for hours when nothing could be farther from the truth.

The beauty of this recipe is in its versatility. It’s easy to change the flavors by using different sausages. I used the skinny, coiled sausage with a tomato and basil flavor but any sausage will work! Use your favorite.

The dressing packs a ton of flavor with olive oil, Italian seasonings, garlic, dijon and parmesan cheese. It doesn’t hurt that fresh rosemary and potatoes are a natural couple. The aroma of the two cooking together ranks as one of the best – on the list somewhere up near fresh bread. Your entire house will smell absolutely divine.

If you happen to have your kitchen windows open the otherworldly smell will waft its way through your neighborhood causing your neighbors to wonder what you’re cooking and can they come for dinner?

They might show up in your yard. Uninvited. It’s been known to happen. Best keep them windows closed. Or plan on making extra.

Roasted Sausage, Potatoes and Peppers

Italian sausage, potatoes, bell peppers and onions are roasted with fresh rosemary in an olive oil and parmesan cheese dressing.


12 ounces sausage, cut in 2-3" long pieces
4 cups potatoes, cut in 1/2" - 3/4" cubes
3 cups sliced bell pepper, 1/2" wide and 3" long
1 large onion (sliced the same size as peppers)
2 tablespoons fresh rosemary, chopped
1/3 cup olive oil
1 heaping tablespoon dijon mustard
2 cloves garlic, minced
2 tablespoon grated Parmesan, plus more for serving
1 teaspoon Italian seasoning, crushed between fingers
3/4 teaspoon coarse sea or kosher salt
1/8 teaspoon black pepper
extra-virgin olive oil, for serving


  1. Preheat oven to 425 degrees F. Add the sausage, potatoes, peppers, onion and rosemary to an extra large mixing bowl.
  2. In a separate small bowl whisk olive oil and mustard together. Add garlic, parmesan, Italian seasoning, salt and black pepper, whisk until well combined.
  3. Pour over sausage mixture and toss well until everything is coated.
  4. Grease a large, thin cookie sheet with sides and pour out the mixture. Spread evenly over the baking sheet. Bake 30-45 minutes until sausage is cooked through and potatoes are golden and tender.
  5. Serve with parmesan and a drizzle of extra-virgin olive oil.


Delicious served with crusty bread and a tossed salad.

    Planning on making this for a party, using chaffing pans, how will it hold up staying warm for over an hour?

    Omg! Just used this recipe using farm fresh potatoes, onions, and peppers we picked up at a harvest festival today! We went to our grocery store and picked up fresh spicy Parmesan chicken sausage and rosemary. This dish was OUT OF THIS WORLD!!! We haven’t had anything this good in a long time! We kept saying it taste like a special anniversary meal, but it was so easy! Even our 2 year old gobbled it up! This will definitely be going in our rotation!

      Thanks Erin! That is so great to hear! I’m glad it was a hit! I bet it was extra delicious with all that farm fresh produce! :-)

    I’m just wondering (I’m so new to cooking!!) do I need to pre cook anything before putting it into the mixture? Or will it all bake together?
    So excited to make this

    Thanks x

    This sounds delicious! I’m wondering if diced chicken breast will be OK to substitute for the sausage, or will the cooking time be different? Thanks :)

    • Reeni says

      Hi Elisa! Sorry for the late reply! The cooking time would probably be the same! It takes that long for the potatoes to cook so you’d have to do big chunks of chicken so it doesn’t dry out/overcook.
