Raise your hand if you grew up eating Italian sausage and peppers! Sausage and pepper sandwiches with caramelized onions and ooey gooey mozzarella or provolone cheese is one of my all-time favorite dinners. And, it definitely qualifies as comfort food.

As much as I love eating sausage and peppers, I don’t like cleaning up a messy stove. No matter how careful I am, the sausages tend to splatter. And, you have to wait awhile for the onions to cook down.

Sometimes, this isn’t an issue, but on busy days or hot summer days, I don’t always feel like standing over a hot stove. I think that’s why I’m such a huge fan of easy instant pot recipes!

So, I tweaked my usual recipe for Italian sausage and peppers and came up with this quick and easy recipe for pressure cooker sausage and peppers. You get all of that amazing flavor without the mess and without standing over a hot stove. And, the sausages, onions and peppers cook in record time!

How to make Instant Pot sausage and peppers

You make sausage and peppers in the Instant Pot almost like you do on the stove. Start out by browning the sausages for about 5 minutes on the saute setting. You want to get some nice color without cooking them all the way.

Next, take the sausages out, and place them on a large serving platter. To make the cooking go faster, I like to cut the sausages in thirds. Then, cover them with foil, and deglaze the pot.

I just add a little bit of water –maybe 1/4 cup– and this is enough to release any browned bits from the sausage. Then, add the onions, and stir until slightly soft. You can cook them longer and get them nice and caramelized, but if you’re in a hurry, you just need to get them soft, and let the pressure cooker do the rest!

I don’t like super soft peppers, so I just stir them in, add the sausages back to the pot, and add the rest of the ingredients. If you like softer peppers, you can saute them a little longer.

You only need to add a half cup of water because the onions, peppers and sausages will add additional liquid as they cook — any more water, and the sauce gets very soupy. I made this in the 8-quart Instant Pot, but if you’re using a 6 quart, you could easily get away with using just a quarter cup of water.

After just 5 minutes of pressure cooking, dinner is ready! You can now make some awesome Italian sausage and pepper sandwiches, or you can serve the sausages over pasta or eat them just as they are.

To make Italian sausage and pepper sandwiches

  • Use bolillo rolls or other thick, crusty bread rolls
  • Place sliced provolone cheese on bottom of cut rolls and bake for a few minutes until cheese is melted
  • Add sausage, peppers, onions and tomatoes, and top with shredded mozzarella

I recommend wearing oven mitts and using stainless steel tongs to turn the sausages, as they may splatter when cooking on saute.

    This recipe for Sausage and Peppers is a keeper! Absolutely delicious. I just made 10 lbs of sausage last night for a funeral luncheon today. Prepped a whole lot of Peppers and onions and sausage, that’s for sure! I used the stove to brown the sausage but once it was ready, I used the Instant Pot and made it in 3 batches. Absolutely wonderful! There was none left to bring home! Thank you for such a great recipe!

    What a wonderful recipe! My Half-Italian ex made a version of this on the grill and the stove that I loved but this is just as good and a lot easier.

    Bravo!5 stars

      Thank you so much, Miki. I’m glad you liked it!

  3. Debbie says:

    This was delicious, but the sauce was thinner than I would have liked. It was certainly easy to throw together. I will make it again, but would probably cut the amount of water added and/or use crushed tomatoes instead of diced. It’s a keeper!4 stars

    Just made this for lunch. Delicious! I used Rotel tomatoes since I was using sweet Italian turkey sausage because of a mammal meat allergy. I do think I will cut back on water or drain tomatoes and use beer next time. I saw the comment about using this will gnocchi and I cant wait!5 stars

      Thanks, Rose — glad you liked it! I want to try the gnocchi next time, too!
