Ingredients Needed

  • olive oil or any vegetable oil
  • bell peppers
  • onion
  • smoked paprika
  • garlic powder
  • Italian seasoning
  • celery seeds
  • Italian sausage

Bell peppers – This recipe calls for red, orange, and yellow bell peppers as I prefer to varying degrees of sweetness these varieties offer; however, feel free to throw in a green if you prefer a more bitter element. When purchasing be sure to only pick the firm, smooth-skinned fruits.

Onion – Traditionally sausage and peppers are made with sliced sweet onion, but feel free to use white or even red.

Italian seasoning – I like to use my homemade Italian seasoning but you can use your own mixture of oregano, onion powder, garlic powder, basil, and other spices you enjoy.

Italian sausage – Italian sausage can be purchased from the butcher counter at most grocery stores or can be found prepackaged with other meats in the open cases. Feel free to use hot, mild, or sweet Italian sausage for this recipe. You could also swap in chicken or even turkey sausage if you prefer those flavors over pork.

How to make sausage and peppers in the oven

First: Preheat oven to 400°F. In a large bowl, add sliced peppers and onions.

Second: Add in olive oil and gently mix to coat all the peppers and onions. Sprinkle in the spices and mix until vegetables are evenly coated.

Third: On a prepared cookie sheet, place all the vegetables and evenly spread.

Fourth: Cut the sausage into bite-size pieces and add to the cookie sheet. Cook for 25 to 30 minutes or until the sausage reaches an internal temperature of 165°F. Enjoy!

How long do sausages take in the oven?

Since the sausage is cut into bite-size pieces that are about ½ inch thick, it will take approximately 25 to 30 minutes for the sausage to reach an internal temperature of 165°F. If you cut the sausage thinner, it will take less time, and if you cut them thicker than the ½ inch, it will take longer.

So you cook onions first or peppers?

While you can cook the onion and peppers separately, the beauty of this recipes is everything gets cooked together on one pan! You can cook them before and add the onions an peppers later but why make more work for yourself?

How do you cut onions for sausage and peppers?

I recommend slicing the onion into approximately ½ inch to 1-inch-thick pieces. Anything smaller, the onions will cook too fast, which can result in a burned onion. If the onion is cut too large, it will still need time to crisp and soften after the sausage is cooked.

What is the best kind of sausage to use?

You can use hot, mild, or sweet Italian sausage. Feel free to swap in chicken or turkey sausage if you’d prefer!

Can I freeze it?

Yes, you can! Allow leftovers to completely cool. Once cooled, place in a freezer safe bag or container in the freezer for up to 2 months. When ready to enjoy, allow to thaw overnight in the fridge, place on a prepared sheet pan, and place in a 350°F oven until warmed through.

Leftovers?

Store any leftovers in an airtight container up to 4 days in the fridge.

When ready to enjoy, heat in the microwave at 30 second intervals until warmed through. Enjoy leftovers on a toasted hoagie bun with cheese, or toss with some pasta and tomato sauce, or better yet, top a pizza with them!

Tips for No Leftovers

  • Use the red, yellow, or orange peppers as they are the sweetest.
  • I prefer to use Vidalia or sweet onions.
  • Slice the peppers and onions into the same size for even cooking.
  • Spice up with a sprinkle of red pepper flakes.
  • Use foil or parchment paper to prep your baking sheet for easy clean up.
  • You could also use mini sweet peppers in place of bell peppers.
  • Serve on a toasted hoagie roll with marinara sauce, over rice or pasta, or enjoy on it’s own!
