How to Make Irish Stew With Mashed Potatoes | The Cagle Diaries

1. Heat the vegetable oil in a large heavy-bottomed pot over medium-high heat. Season the lamb cubes with salt and pepper, then brown them in batches until a nice crust forms, about 5 minutes per batch. Remove and set aside.
2. In the same pot, add the chopped onion and garlic, cooking until softened and fragrant, about 4 minutes. Return the lamb to the pot and stir to combine.
3. Add the beef or lamb broth, dried thyme, and bay leaves. Bring to a boil, then reduce heat to low and cover. Let the stew simmer gently for 1 hour 30 minutes, stirring occasionally.
4. Add the carrots, pearl onions, and diced potatoes to the pot. Continue simmering uncovered for another 45 minutes, or until the vegetables and lamb are fork-tender. Season with additional salt and pepper to taste.
5. While the stew simmers, prepare the mashed potatoes. Peel and cut the russet potatoes, then place them in a pot of cold salted water and bring to a boil. Cook until very tender, about 20 minutes.
6. Drain the potatoes well and return to the pot. Mash with butter and warm milk until smooth and creamy. Season with salt and pepper.
7. Remove bay leaves from the stew. Serve the Irish stew hot, ladled over or beside a generous portion of creamy mashed potatoes. Garnish with fresh parsley for a pop of color and flavor.

Tips for the Best Results

• Use lamb shoulder for the best balance of tenderness and flavor in the stew.
• Don’t rush the simmering step—low and slow cooking makes the meat melt-in-your-mouth tender.
• Peel pearl onions easily by blanching them in boiling water for 30 seconds, then shocking in ice water.
• Warm your milk before adding it to mashed potatoes for extra creamy texture.
• Season gradually and taste throughout cooking to perfectly balance the flavors.

Storage and Reheating

Store leftover Irish stew in an airtight container in the refrigerator for up to 4 days. The flavors tend to deepen with time, so leftovers are even better the next day. Mashed potatoes can be stored separately in the fridge for up to 3 days.

To reheat, gently warm the stew on the stovetop over low heat, stirring occasionally. Reheat mashed potatoes in the microwave or on the stovetop with a splash of milk or butter to regain creaminess.

Frequently Asked Questions

Can I substitute beef for lamb in this Irish stew?

Yes, you can substitute beef stew meat if you prefer. The flavor will be slightly different but still delicious and hearty. Just use the same cooking times and method.

What type of potatoes work best for mashed potatoes?

Russet potatoes are ideal for mashing because they break down easily and result in a fluffy, creamy texture. Yukon Golds can also work but may produce a denser mash.

Can I make this stew in a slow cooker?

Absolutely! Brown the lamb and sauté the onions as directed, then transfer everything to a slow cooker. Cook on low for 6-8 hours or high for 3-4 hours until the meat is tender.

How do I peel pearl onions quickly?

Blanch pearl onions in boiling water for about 30 seconds, then plunge into ice water. This loosens the skins and makes peeling much quicker and easier.
