The ultimate comfort food for St. Patrick’s Day has to be this Instant Pot Irish Beef Stew. Warm, hearty, and rounded out with some Guinness, it is one of my favorite stews to serve over mashed potatoes. Pair it with more Guinness or your favorite cider!

A meaty, hearty stew is what really feeds my soul, no matter what the temperature might be outside. 

The first time I tried Irish stew was actually IN Ireland. Pretty lucky, if I do say so myself.

It was on a tour of Ireland that would take me to the gorgeous Cliffs of Moher. Halfway through there was a stop at a small pub that included a lunch of Irish beef stew. This was at a time when I didn’t really LOVE soup and stew, but it was the one thing on the menu that sounded delicious at the time (probably because it came with a huge thing of bread and butter…).

The stew was made with Guinness and it was miraculous. So full of simple flavors and absolutely comforting in the best way. I felt like I was being hugged from the inside out, which was something I definitely needed after hours of hopping on and off a crowded bus. 

It’s taken me years to actually make a version in the Instant Pot. I wanted to make it hearty and flavorful, but I didn’t want it to cook under pressure too long. 

After a couple tries, this is the recipe I came up with. Honestly, it’s super straightforward, and that’s how I want it to be! This is one of those recipes that you can easily throw together in just over a half hour, so it’s perfect for a weeknight.

This Recipe’s Must-Haves

Obviously, you’ll need an Instant Pot! For me, the Instant Pot Ultra is my favorite model because it’s easy to use and isn’t the priciest one available.

You’ll also need a chef’s knife and a cutting board (or two) to cut up the beef and other veggies. 

Finally, make sure you have a wooden spoon. I love using these whenever I am making a stew that starts with searing meat. It helps with getting the browned bits off the bottom, which is especially important in the Instant Pot.

We’re making Instant Pot Irish Beef Stew!

Sear Beef and Cook Veggies

With your Instant Pot on the Sauté function, heat up the oil and then drop in the beef. You’ll cook the beef until it’s browned on all sides, then remove it from the insert. After that, add in the veggies (onions, celery, and carrots) and cook those down. 

After this you’ll add in a few ingredients, letting the mixture cook a little after each addition as noted. 

Finally, you stir in the rest of the ingredients and switch the Instant Pot to Manual.

Pressure Cook

This stew cooks up really quick! Only 20 minutes on High pressure and you are ready to release pressure manually.

Make Slurry and Finish

To thicken the stew up a bit, you’ll make a slurry and add it in. Then you cook it over the Warm setting, until it’s thickened up just a bit. After that, it’s time to serve! I LOVE to serve this stew with mashed potatoes, but you can also just serve it up in a bowl with a hunk of crusty bread.

Got questions?

Can I make this on the stovetop?

You can! You would simply follow the steps as outlined except you will be sautéing in a Dutch oven. Instead of cooking on Manual pressure for 20 minutes, you’ll bring the stew to a simmer and cook it for 30 to 45 minutes until the potatoes are cooked through. 

Do I have to serve it with mashed potatoes?

No, you don’t! Sometimes it’s too much, and I totally get that. So instead you can simply serve this stew up in a bowl and eat it as is. You can pair it with a big piece of crusty bread if you want!

Can I substitute lamb for the beef?

Yes, you definitely can! You don’t need to make any adjustments to the recipe, a straight substation works.
