This Instant Pot Lamb Stew is an easy dinner that is full of flavor! Lamb cubes are simmered in Guinness and combined with carrots and potatoes for a hearty Irish stew recipe that will warm you up on a cold day. Perfect for St. Patrick’s Day!

Lamb isn’t the most commonly used meat in American cooking, but it is delicious. Lamb has a tasty and deep flavor which complements a wide variety of cooking, from Irish to Mediterranean. 

I have made Irish Lamb Stew for years, but once I got a pressure cooker I wanted to make a lamb stew recipe in my Instant Pot. The Instant Pot is perfect for making stews, because it allows you make it without hours of cooking.

Using a pressure cooker like the Instant Pot means you can have tender meat without simmering the meat for 2-3 hours. And to make it even better you can brown the meat right in the Instant Pot with the saute function, so there are fewer dishes to wash. 

Quicker cooking combined with fewer dishes make the Instant Pot ideal for making stews! If you aren’t in the mood for lamb check out my Instant Pot Pork Stew or Instant Pot Chicken Stew with Squash.

Ingredients for Instant Pot Lamb stew with Guinness

Key Ingredients

  • Lamb meat, cubed – This can be made with any kind of cubed lamb. Shoulder meat is commonly used and if you can find pre-cubed lamb stew meat it will probably be from lamb shoulder. Leg meat also works well. Lamb shoulder is a little tougher than lamb leg, but cooking it in a stewing it makes it tender.
  • Guinness stout and broth – I prefer to use Guinness for a rich and unmistakable flavor. It also complements the lamb and makes it distinctly Irish. But you can substitute another kind of beer, broth or wine.
  • Flour and tomato paste – These help thicken the meal so it is more stew like and less soup like.
  • Vegetables – I include onions, carrots and potatoes. Other root vegetables or celery would be a good addition if you want to add even more vegetables.
  • Seasoning – Salt, black pepper, thyme, rosemary and mustard all combine to make this dish flavorful and delicious.

How to Make Irish Lamb Stew with Guinness

1. Brown the Lamb

Put the Instant Pot on Saute and let it heat up for a few minutes. Then add oil to the Instant Pot and add the lamb cubes.

browning lamb

Brown them, stirring, until they are mostly brown, about 5 minutes. Then add the onion and stir to let it soften and brown for 2 minutes.

2. Deglaze the Instant Pot

Turn the Instant Pot off and add the broth. Stir, scraping the bottom of the Instant Pot to get off all the bits of browned meat and onion on the bottom of the Instant Pot. This will help reduce the chances of getting a Burn error from the pressure cooker.

Now add the flour, thyme, rosemary, Guinness, tomato paste, mustard, salt and pepper to the Instant Pot. That is everything except the potatoes and carrots!

adding Guiness and broth

Stir to mix everything together in the pressure cooker. Then put the lid on the Instant Pot, locking the lid and making sure the valve is shut.

Pressure cook the stew for 20 minutes on Manual/Pressure setting. The Instant Pot will take about 10 minutes to reach pressure and start counting down the time.

4. Add the Vegetables

While the lamb cooks in the Instant Pot you can cube the carrots and potatoes. To ensure even cooking make the pieces about the same size, 1 inch or less in size. 

I usually peel the potatoes, but that is not necessary. Once the Instant Pot is done cooking do a quick pressure release and remove the lid. 

adding carrots to stew

Now add the carrots and potatoes and put the lid back on the Instant Pot. If you have a hard time getting the lid to reseal run a little cold water on it to cool it off.

Set the Instant Pot on Manual/Pressure for 10 minutes to cook the vegetables. It should come to pressure more quickly this time since everything inside is so hot.

5. Finish

Once the Instant Pot finishes use either the quick pressure release or natural pressure release, depending on how soon you want to serve dinner.

If the stew is not thick enough for your tastes mix 2 Tablespoons of cornstarch with 2 Tablespoons of cold water and cook it on saute for 5 minutes until it bubbles and thickens.

How to Avoid Mushy Stew Vegetables

One thing my family and I don’t like is when the vegetables in our stew are mushy and fall apart! That is why I bring the Instant Pot up to pressure twice – first to cook the meat and then to cook the vegetables.

You could add the potatoes and carrots at the beginning and only bring the pressure cooker up to pressure once. It would still taste good but the texture would be a little different and the vegetables’ texture would not be as firm, so I prefer to take a little more time and not overcook the vegetables.

How to Serve Instant Pot Lamb Stew

This hearty stew is a complete meal in itself. But if you want to stretch the meal you could serve it with a green salad or over noodles. I like to garnish it with fresh parsley or thyme.

It also tastes delicious with a crusty bread – especially a beer bread! And if you are a fan of Guinness then make sure you have a few bottles to serve with dinner!

How to Store

Leftovers can be stored in the refrigerator for up to 3 days. The flavors will deepen and I think it actually tastes better on the second and third day. 

This lamb stew recipe freezes well and will keep for about 3 months in the freezer. Thaw it overnight in the refrigerator and heat it over low heat on the stove.

Frequently Asked Questions

Can I make this with frozen lamb?

Yes, frozen lamb works fine in this recipe as long as it is cubed before it is frozen. If the meat is frozen searing it before pressure cooking isn’t really effective. Increase the initial pressure cooking time to 30 minutes if the meat is frozen.

How do I make this gluten free?

Guinnes contains malted barley, so I don’t think it is technically gluten free. So you would need to substitute a gluten free beer for the Guinness, in addition to replacing the flour in the recipe with a gluten free thickener.

What can use instead of Guinness?

You can substitute chicken broth, another type of beer or red wine for the Guinness. All would change the flavor somewhat, but it will still be a delicious stew, just less Irish!

This Instant Pot Lamb Stew is an easy Irish Dish perfect for St. Patrick's Day dinner.

Prep Time 10 minutes
Cook Time 30 minutes
Reach Pressure 15 minutes
Total Time 55 minutes

Ingredients

  • 2 Tablespoon oil
  • 1 pound lamb stew meat, cubed
  • 1 yellow onion, medium, diced
  • 2 cups chicken broth
  • 1 cup Guinness Stout
  • 2 Tablespoon flour
  • 1 teaspoon dried thyme (or 2 Tablespoons fresh)
  • 1 teaspoon dried rosemary (or 2 Tablespoons fresh)
  • 1 1/2 Tablespoon Tomato paste
  • 1 teaspoon Dijon mustard
  • salt and pepper to taste
  • 2 medium potatoes
  • 3 carrots

Instructions

Note - This recipe was originally published in 2019. I recently revised it to add some information on deglazing the Instant Pot because a few people reported they were receiving a Burn error. The recipe hasn't changed, but I'm suggesting adding the ingredients in a slightly different order now.

  1. Set the Instant Pot on Saute and let it heat up.
  2. Put the oil in the Instant Pot and brown the lamb cubes on all sides in the oil.
  3. Add the onion to the Instant Pot and let brown for 2 minutes.
  4. Turn the Instant Pot off. Add the chicken broth to deglaze the Instant Pot. Scrape the bottom with a wooden spoon or spatula to remove any browned bits of meat and onion that have stuck to the bottom. This reduces the changes of getting a BURN error.
  5. Add the Guinness, flour, thyme, rosemary, tomato paste and Dijon mustard, along with salt and pepper to taste. Stir to mix.
  6. Put the lid on the Instant Pot and lock the lid. Switch it to the Manual/Pressure setting and program it for 20 minutes on high pressure.
  7. While the stew cooks peel and dice the potatoes and the carrots.
  8. When the 20 minutes is done release the steam using the quick pressure release.  
  9. Add the potatoes and carrots, and lock the lid back on the Instant Pot. Run the lid under a little cold water to cool it off if it doesn't want to reseal. Set the Instant Pot to Manual/Pressure on high pressure for 10 minutes.
  10. Once the 10 minutes are up use either the quick release or natural release, depending on how soon you want to serve dinner.

Notes

Avoiding mushy stew vegetables

I prefer to make this as the recipe describes, by pressure cooking twice, once to cook the meat, once to cook the vegetables. This keeps the vegetables from overcooking and being mushy. But you can add potatoes and carrots with the rest of the ingredients and only pressure cook the stew once, for 30 minutes, if you want to make it more quickly.

Making with frozen lamb

Increase the initial pressure cooking time to 30 minutes if the lamb cubes are frozen.

Substitutions for Guinnes

Use more chicken broth, wine or another type of beer if you don't have Guinness.

  1. I am very upset. I made this recipe for 8. It said to use 4 cups of chicken broth and 2 cups of Guinness. Not only do I now have soup, it was a complete waste of good Guinness! I checked 4 times to make sure the recipe included the broth. Perhaps you will want to check your recipe/directions. If these are NOT the correct values for doubling the recipe, a correction would be greatly appreciated. I am glad I used beef instead of 2 lbs of lamb. I have never written a review on anything like this before, but people should be warned to not follow directions, but go with their gut. This is for a gathering, not just family.

  2. My deepest apologies. I’m eating humble pie along with my stew. I realized that I had used a gluten-free flour mix which may have caused a problem with the thickening. I am using a different flour to make gravy and hopefully rectify the situation. I should have not written the review until everything was done. The flavor is good.

    • Love love love. I followed explicitly to your instructions. The only difference was I added a few stalks of fennel. This stew came out delicious and nutritious and I am saving it to my Pinterest instant pot board. Thank you so so much.

  3. Delicious! Easy. It’s all the things I like about a recipe. I’m making it again for a crowd. Yum! Although, I think I used sherry the first time I made it, and I just used red wine for the second round. Still great! I don’t care much for Guinness, so I didn’t put it in.

  4. I followed the recipe to a “T” and my Instant Pot kept defaulting to overheating. I even went to low pressure and still got the overheating error. I am now letting it cool down and will transfer to a pot for my stove. If this works, I will be happy as this smells incredible and my husband and I are really looking forward to trying this stew.

    • This turned out great even though I had to transfer stew to a pot for my stove to finish cooking. Will be making this again and will try using my instant pot again.

  6. Great Recipe! I removed about 2 cups of the vegetables and used my immersion blender in the instant pot.. then added the vegetables back in. The taste was fabulous! This recipe is a KEEPER!

  7. Great recipe!
    My daughter is gluten free so I substituted Glutenberg IPA (gluten free beer) for the Guinness and used Bob’s Red Mill 1 to 1 Gluten Free Baking Flour instead of wheat flour plus my wife is allergic to rosemary so I substituted a tbsp of Montreal Steak Seasoning. We also made some Bob’s Red Mill Gluten Free Cornbread to dip in the stew. It was so delicious and my family loved it!

  8. I am on my second time of making this and we substituted arrow root for flower since we are GF in the house right now. Followed the rest of the recipe and it turned out amazing. My wife and I love this. We are also using a pampered chef quick cooker and the timeline is the same. I am excited to try this the second time around.

  9. This is my husband’s favorite meal that I make. I have tried many of your recipes and they are all amazing. Please keep them coming. I enjoy them, especially since I was raised and currently live in Upstate NY as well.
