Ireland doesn’t always have a reputation for producing culinary masterpieces, but there a lot more to Irish food than just adding green coloring to a dish.

Easy dinners like Instant Pot Corned Beef and Cabbage or Instant Pot Lamb Stew are newer takes on old favorite Irish dinners. So try an Irish inspired dinner this week.

Bangers and mash is classic English and Irish pub food. The simple combination of sausage and mashed potatoes is topped with a tasty and creamy onion gravy.

Using the Instant Pot to make bangers and mash makes it an easy one pot dinner. The sausages cook in the gravy while the potatoes steam resulting in an easy 30 minute dinner!

Why are the Sausages Called Bangers?

During World War II food rationing led to a lot of filler being added to sausages in Great Britain. The filler, especially when it was water, would make the sausages pop and bang as they cooked, leading to them being called bangers.

What Kind of Sausage are Bangers?

The most traditional kind of sausage used in bangers and mash is Irish sausage which combines pork with breadcrumbs and flavors like mace for a unique flavor. Cumberland sausage is also commonly used in Britain.

A few years ago I noticed that my local Wegmans grocery store was carrying Irish style bangers and you can also buy bangers online. Obviously those sausages are perfect for this dish and it make a delicious St. Patrick’s Day dinner.

But even if you can’t find Irish bangers you should still make this recipe! I made bangers and mash for years with just standard pork sausage. You can use any kind of good quality sausage.

While pork is the most traditional sausage meat used for the meal beef, lamb or chicken sausage could also be used. I probably wouldn’t use a spicy sausage, but pretty much anything else would be tasty.

In addition to the bangers the remaining ingredients are

For the potatoes red potatoes, yellow potatoes or russet potatoes all will work fine in this dish, although russet potatoes will probably need to be peeled. Two pounds of potatoes are plenty to serve four people.

I used a combination of beef broth and Guinness Stout to make the gravy. The Guinness gives the gravy a deeper and richer taste and makes the dish seem more Irish.

But the beer will give the gravy a little bit of bitterness, and you can use all beef broth or substitute a different kind of beer.

Why Use the Instant Pot?

I’ve been serving bangers and mash to my family for years, and in fact originally posted a recipe for it on my blog 9 years ago. I read a lot of British murder mysteries and kept seeing it mentioned as a common food, so I was curious and decided we should try it.

And once my family and I tried it we loved the taste sausage served with creamy potatoes and rich gravy. But the recipe didn’t become frequent in our meal rotation until I started making it in the Instant Pot.

I like to use the Instant Pot because it makes bangers and mash a one dish meal, all made in the pressure cooker. It isn’t really any quicker to make in the Instant Pot, but it is easier because it all cooks together and is ready all at once.

I also strongly prefer to make mashed potatoes by steaming them in a pressure cooker and haven’t made them any other way since I got my first Instant Pot. So if I am using the Instant Pot anyway for the potatoes I might as well cook the sausage too.

How to Make Instant Pot Banger and Mash

The general idea for cooking this entire dish in the Instant Pot is to cook the bangers in the onion gravy while the potatoes steam.

1. Prepare the Potatoes

Dice the potatoes into cubes of about 3/4 of inch size. I used red potatoes and left the skins on because I hate peeling potatoes. But you could peel the potatoes if you prefer.

Put the potatoes in an Instant Pot steamer basket and set them aside for a few minutes.

2. Brown the Sausage and Onion

Turn the Instant Pot on Saute and let it heat for a couple minutes. Then add the oil, onions and sausage. Cooking, stirring the onion and turning the sausage for about 5 minutes.

sauteing the sausages in the Instant Pot

The onion should soften and the sausage should brown slightly. After 5 minutes stir in the garlic and turn off the Instant Pot.

3. Deglaze the Instant Pot

Pour the beef broth in the Instant Pot and stir to remove any browned bits of onion or sausage from the bottom of the inner pot. If you don’t remove browned food from the bottom you might get an burn error when the Instant Pot comes to pressure.

If you need to take the sausage out of the Instant Pot and put them on a plate to make sure there is nothing stuck to the bottom. Personally I have never had much issue with sticking with this recipe, but check to be sure.

4. Bring the Instant Pot to Pressure

Add the Guinness and the Worcestershire sauce to the Instant Pot. Then put a trivet in Instant Pot and set the steamer basket with the potatoes on top.

Put the lid on the pressure cooker, making sure the seal is in place and the pressure valve is closed. Set the Instant Pot on Manual, high pressure for 8 minutes. It will take about 10 minutes for it to reach pressure.

5. Finish the Gravy and Mashed Potatoes

Once the Instant Pot has finished let the pressure release naturally for at least 5 minutes. After that you can release the remaining pressure manually.

Take the steamer basket of mashed potatoes out and dump it in a serving bowl along with the cream and butter. Use tongs to take the bangers out of the gravy and put then on a serving platter. Let the potatoes and sausage sit for a minute while you finish the onion gravy.

thickening the sauce with cornstarch

Mix a couple tablespoons of cold water into the cornstarch and add the mixture to the onion gravy. Stir, then put the Instant Pot on saute and stir again. Cook until the cornstarch thickens the gravy, 2-3 minutes.

mashing the potatoes for bangers and mash

While the gravy cooks use a potato masher to mash the potatoes and mix the butter and cream in. Serve the sausage with the mashed potatoes and top them off with the onion gravy.

What to Serve With Bangers and Mash

The most authentic side dish for bangers and mash is green peas. But since my family and I dislike peas that doesn’t work for us. But some kind of easy green vegetable is a great choice for serving with this dish. We like air fryer green beans or sauteed zucchini.

Notes

If you can't find Irish bangers use another mild flavored sausage.

You can use all beef broth if you don't wish to use Guinness to make the gravy.

I test and make my recipes in a 6 quart Instant Pot. A different model or size of pressure cooker might give you different results.
