Why You'll Love Oven Baked Italian Sausage

This baked Italian sausage recipe couldn't be easier. You only need a few ingredients and it only takes a few minutes of hands-on time to pull together.

There are my different ways to cook sausage, but baking sausages is one of the easiest ways to cook them. It's largely hands-off, you only need to flip them once. And you don't have to worry about burning them on the grill or having water boiling over on the stove.

By adding some vegetables you can make this a fantastic sheet pan dinner, that involves hardly any cleanup!

Ingredients You'll Need

To make Italian sausages in the oven, all you really need is a few sausage links, a sheet pan, and either parchment paper or aluminum foil.

If you want to make sausage with some roasted vegetables, here's what you'll need.

Sausage - 1 pound of Italian Sausage. This will usually be anywhere from 3 to 5 links, depending on how large each link is. You can double or triple this recipe if you are cooking for a larger group.

You can use the more traditional pork sausage for this recipe, but chicken sausages will work as well.

You can use sweet (or mild) Italian sausage or hot Italian sausage. Sweet Italian sausage is simply the less spicy of the two and is made without red pepper flakes.

Tomatoes - 2 cups cherry or grape tomatoes. Use whatever tomatoes you have available - I had a colorful mix of baby heirloom tomatoes.

Bell Pepper - 1 red or orange bell pepper. You'll remove the seeds and cut into thin strips.

Toppings - 1 tablespoon olive oil, 1/2 teaspoon sea salt, and 1/4 teaspoon ground black pepper.

Optional - feel free to top this with some roughly chopped fresh herbs, a drizzle of balsamic vinegar, or a little tomato sauce.

How to Bake Italian Sausage in the Oven

Here are the simple steps for this Italian sausage bake.

Preheat oven - Preheat oven to 400 degrees F (205 C). 

Line a baking sheet - Line a half or quarter sheet pan with parchment paper or aluminum foil.

Add the sausage - Place the sausage on the baking sheet, making sure to leave space between them. 

Bake - Place the sheet pans in the oven and bake for 10 minutes. Flip the sausages over. If they look like they might burst, prick them with a fork a few times. Return the sausages to the oven and bake for an additional 10 minutes. 

Check temperature - Check the internal temperature of the sausage, they will be done when they read 160 degrees F on an instant-read thermometer. 

Serve - Remove sausages from the oven and serve immediately with optional vegetables.

Optional vegetables - If you are making the vegetables, toss the tomatoes and sliced bell peppers with olive oil, salt, and pepper. Spread them flat on a separate parchment or foil lined baking sheet. Bake for 20 minutes (along with the sausage).

Tips for Making this Recipe

Cooking Tips - The cooking time may vary based on the size of your sausages. If they are smaller links (5 in a package), check them after 18 to 20 minutes. If they are larger (3 to 4 in a package), they will likely take closer to 25 minutes.

Recommended Tools - Use a meat thermometer or instant-read thermometer to check the temperature of the sausage (it's done at 160 degrees F).

You can use a baking tray for this recipe, but I do recommend a rimmed sheet pan. In case the sausages release any juices, they won't slosh out and burn in the oven.

I highly recommend using parchment paper or aluminum foil to line your sheet pan, it keeps the sausage from sticking to the bottom of the pan and makes cleanup much easier.

Storing Tips - Cooked sausages will keep for 3 to 4 days in the refrigerator when stored in an airtight container.
