Italian sausage in oven with peppers and onions at 400 is a cheap pork dinner. If you loved our air fryer Italian sausage recipe but want that snap alongside vegetables, you’re going to love this way to bake them on a sheet pan.
This is a quick meal. Add some peppers in there and it is almost like a baked stir fry you can make in under 30 minutes. We will talk about Bratwurst in the Oven, raw Italian sausages or kielbasa will take even less time. Easy sheet pan meal that costs less than ten bucks to feed everyone. (affiliate links present)
How Long to Bake Italian Sausage in Oven
This is the pork sausage we are talking about, not Sausage Patties in Oven you make for breakfast, though you could do the same thing with those. The type of sausage (flavor or brand) doesn’t really make a difference, the size will vary the cooking time though. In general 20 minutes does the trick though. 😉
For both these and our Venison Sausage a higher temp. is the best. You want a snap on the outside with tender middle, this does just that. To cook in the oven you just need a baking sheet lined with parchment or non stick aluminum foil for easier clean up. Bake sausages with the casing on or remove it with a sharp knife at the beginning.
Ingredient Notes
- You will be able to bake a whole package of spicy or sweet Italian sausages are we love, fresh is best but we will talk about frozen below. For lower fat choices, I have seen turkey sausage and chicken sausage varieties (but flavors aren’t as bold).
- I add a few sliced bell peppers with whatever color is on sale. Red, orange and yellow are sweeter than green so use whichever you like.
- 1 onion sliced is a nice touch especially if you are making bangers and mash or serving on hoagie rolls to add veggies
- You will want some olive oil or avocado oil to keep them moist on the outside so they don’t dry out.
- Seasoning to us isn’t really needed other than the onions and peppers as the links already have plenty of that mixed into the raw meat. Many times I will top the meat with mustard sauce for corned beef on top which has a bit of a sweet kick.
Tips
Biggest thing to remember is everything needs to be in a single layer so they get tender. Overlapping will not allow the heat to surround your pieces adequately. OR cook veggies separate like Cabbage and Bacon Recipe on the stove at the same time.
Like London Broil in the Oven you want to check often so they don’t over-cook and dry out.
with Frozen Sausage
Believe it or not it doesn’t really matter as far as the baking or Johnsonville air fryer frozen sausage timing goes!! With either of these you always need to check the internal temperature before consuming to ensure it is 160 F when done. Even if they take a bit longer because of their thickness the veggies can take a bit more baking.
If you wanted to make Air Fryer Sausage and Potatoes you could. Now remember that you want everything to be done at the same time so you want to dice those into small pieces. What I do once in 1″ squares I will toss with some olive oil, add seasonings, toss in a bowl and spread out on to the sheet pan.
If you want long links you can often times find them connected at your local butcher shop. Those are kinda’ fun when serving. You will need a large pan in order for them to fit, and may not have space for the veggies.
Cooking rope sausage in the oven is a straightforward method that yields delicious and evenly cooked results, making it a great option for a variety of dishes and occasions. Keep in mind that when serving there will be a bit more work. Since they are linked together you have to fit on a cutting board and slicing apart which is a bit messy with the juices that release.
Serving ideas would be to open up large hot dog buns or on top of a bed of mashed potatoes.

How to save leftovers
If you have leftovers they save quite well if packaged up properly from the get go. First off, after you cook Italian sausage you need to let them cool first. Sausage links need to be sealed in airtight freezer bags so they don’t dry out. Then you can reheat the next day in a preheated oven again for a few minutes with the oven temperature at 300.
Or is you wanted to make something new next day low and slow, try out Crockpot Cabbage and Sausage recipe. That one turns out amazingly well but I don’t always have all day to cook dinner. If I only have 30 minutes to throw something together that is hearty, protein packed and full of flavor this is always a family favorite meal.
FAQ
About 20 minutes on a parchment paper lined baking sheet is perfect for raw sausage in oven to reach the safe internal temperature of 160 degrees F. This will vary depending on thickness and size but typically you’ll achieve tender insides with a crisp snap in the casing. Precooked kielbasa can be cooked in half that time since you’re just warming it up.
It isn’t entirely necessary unless you want to make sure you get a golden brown crispness on the outsides all the way around. If so you will want to rotate them to the other side halfway thru and not overlap any vegetables, onions or peppers on the top of them.
