    Bake Sausage, Peppers and Onions in the oven and you'll never go back to making them on the stove! Ready in less than an hour, this is the best sausage and peppers recipe! It's a fantastic, sheet-pan dinner.

    Are you still making Italian sausage and peppers on the stove? Because baking them in the oven is where it’s at.

    I’m talking juicy, browned sausage, caramelized onions and peppers and knock-your-socks-off flavor. With barely any effort. Ready in less than an hour.

    Read on, if you want to become known as the sausage queen or king. (And don’t miss my Italian Peppers in Oil!)

    I've been baking sausage, peppers and onions for more than 25 years. I decided I had no patience for the stovetop method and needed something easier.

    I’ve now made this hundreds of times and get asked to bring it to parties!

    I first shared this easy sausage and peppers recipe in 2014, soon after I launched Cooking with Mamma C. That night, I heard from four friends who’d each made it for dinner.

    They raved at the results. Their families were happy. This is the best sausage and peppers recipe, folks!

    Recipe ingredients

    raw Italian sausage, peppers, onion, seasonings, oil

    Sausage: I usually use sweet Italian sausage, but you could use hot Italian sausage if you know people won't mind. We've also enjoyed substituting:

    • Chicken sausage
    • Kielbasa (raw or pre-cooked will work)
    • Chorizo

    Peppers: I always use my favorite trio of bell peppers — red, yellow and orange. They're sweeter than green peppers and look gorgeous.

    Onions: You can use red, white or yellow onions here. Red onions will add a little sweetness, which I love.

    How to bake sausage, peppers and onions

    See the card at the end of this post for the full recipe, but here's an overview.

    raw sausage links, sliced onions, peppers on sheet pan

    All you need to do is place the sausage in a greased baking pan. A dark roasting pan (affiliate link) is ideal for caramelizing, but a half-sheet pan (affiliate link) will do.

    Add sliced peppers and onions, drizzle everything with olive oil, and add salt, pepper and garlic powder. Then you'll bake it uncovered, turning over the sausage and stirring around the vegetables just past the halfway point.

    Roast the sausage and peppers at 400 degrees for 45 minutes, which will get everything caramelized quickly. Even a few of the onions will start to blacken (we like that.)

    Recipe tips

    • Turn over the sausage when the first side is browned. You want to brown both sides for the best flavor.
    • Stir the peppers and onions around when you flip the sausage, so they won't stick and will cook more evenly.

    Making sausage and peppers for a crowd

    • Plan on buying one Italian sausage link per person at a minimum. Go with 1 ½ links per person if you want leftovers.
    • To make baked sausage and peppers for a crowd, cut each sausage link in half for smaller portions.
    • Bake at 400 degrees F as directed in the recipe card. (I used to bake it longer at 375 degrees F, but now prefer the quicker baking time at higher heat.)
    • To accommodate large quantities, you can use foil roasting pans (affilate link). They won’t brown everything as well as a metal pan, but transferring the cooked sausage and peppers to a chafing dish (affiliate link) with a flame underneath takes care of that.
    • If there won't be a chafing dish with a flame, you can bake the Italian sausage, peppers and onions in dark roasting pans or sheet pans so they brown nicely, then transfer the cooked food to large foil pans. The sausage and peppers can stay out for up to two hours without being heated.

    What to serve with it

    Whether you’re making this for a party or an easy weeknight meal, make sure you have fresh Italian bread on hand. (You’ve got to dip that bread in the oil!) Or serve the sausage and peppers on hoagies.

    I also like to serve this with The Best Italian Green Salad and these Oven-Roasted Potatoes.

    And, definitely make enough sausage and peppers for leftovers. They won’t freeze well, but they’ll be gobbled up within a few days anyway.

    How to use leftovers

    • Mixed into pasta (slice the meat into rounds), with Parmesan and olive oil
    • Baked on pizza (cut up the cooked sausage and peppers first.) This Homemade Pizza Dough with Beer is the best!
    • Made into an Italian Sausage and Egg Casserole

    Friends, you need to make these Baked Sausage, Peppers and Onions. Whether you go fancy and serve this meal on dinner plates with forks and knives, or tucked into sandwiches on paper dishes (with olive oil dripping down your chins after each bite), enjoy!

    Frequently asked questions

    How long is cooked sausage good for in the fridge?

    The leftovers are good for up to four days. Refrigerate them in a sealed container and reheat portions in the microwave.

    Can you freeze sausage and peppers?

    I don't recommend freezing cooked sausage and peppers. I've tried it, and the taste and texture aren't the same.

    How long should you bake sausage in the oven at 375?

    It will take 90 minutes to cook Italian sausage and peppers in the oven at 375 degrees F. Bake them uncovered.

    What is the safe internal temperature for sausage?

    According to the United States Department of Agriculture, Italian sausage needs to be cooked until it reaches an internal temperature of 160 degrees F. Sausage made from turkey or chicken needs to cook longer, until it reaches 165 degrees F.

    Ingredients

    • 2 pounds sweet Italian sausage (or chicken sausage, kielbasa or chorizo)
    • 4-6 bell peppers (use red, yellow and orange, sliced)
    • 1 large onion sliced
    • 3 Tablespoons olive oil
    • 1 pinch salt
    • 1 pinch black pepper
    • 1 dash garlic powder
    Prevent your screen from going dark

    Instructions

    • Preheat the oven to 400 degrees. Spray a dark roasting pan (preferred) or a sheet pan with cooking spray.
    • Prepare the peppers by rinsing and patting them dry with a paper towel. Cut a circle around the stems to remove them. Cut each pepper in half and remove the seeds and membranes. Cut the halves in half again. Then slice each one into strips about ½ inch wide.
    • Prepare the onions by cutting off the ends, peeling off the skin, and cutting the onions in half. Then cut each half into vertical slices.
    • Place the sausage in a single layer in the pan. Add the peppers, then onions.
    • Drizzle olive oil on each row of sausage. Lightly sprinkle salt on each row. Then sprinkle on pepper and garlic powder, again being sure to season every row.
    • Bake, uncovered for 45-50 minutes total, turning over the sausage and stirring around the vegetables after 30 minutes. The sausage should be browned on the bottom before you turn it over. If using a 375-degree oven, bake for 90 minutes total, turning over the sausage and stirring the vegetables after about 50 minutes, again waiting for the sausage to brown on the bottom before turning it over.
    • Since ovens vary, be sure to check on the sausage and peppers a couple of times during baking to see if you need to stir them around. Test for doneness by cutting a sausage in half. It should no longer be pink inside.
    • Serve with fresh Italian bread to dip in the oil or serve it in hoagies for sandwiches. Store leftover sausage and peppers in a sealed container in the refrigerator for up to four days.

    Notes

    Here are great ways to use leftover sausage and peppers:
    • Mixed into pasta (slice the meat into rounds), with Parmesan and olive oil
    • Baked on pizza (cut up the cooked sausage and peppers first.) This Homemade Pizza Dough with Beer is the best!
    • Made into a Sausage and Egg Casserole
    If you are making the sausage for a party, cut each sausage in half horizontally to make smaller portions. For more tips, see the article that goes with this recipe.

      I have made this before and enjoyed it. I am making it tonight and wanted to check back and read how you did it. I make enough to have leftover the next day. It is great on a roll too.

      This is my go to recipe for sausage and peppers. I’m even adding whole little red potatoes. The juice (fat) gives potatoes great flavor. Will add some fresh diced garlic and a dash of red pepper flakes for kick.
      Since I have fresh basil in garden, will dice some up for garnish. Thanks for the recipe!

      These were so simple and amazing. I made them for a family reunion and now I keep getting requests to make them for future gatherings. My aunts have raved about them to family members who were not at the reunion so now everyone keeps asking me to make them so they can personally try them. I haven’t told anybody how easy they are!

      If your using the the thin Italian pork sausage ring instead of links, how much less time to cook it in the oven ?

        Hi James - Maybe 25-30 minutes, and then cut one open to see if it's done. The peppers and onions will need to cook for 45-50 minutes though.
