Step‑by‑Step Instructions for Irish Stew With Mashed Potatoes
Step 1: Season and Brown the Lamb
Start by seasoning the lamb shoulder pieces generously with salt and freshly ground black pepper. Heat a large pot over medium-high heat and add 2 tablespoons of vegetable oil. Once the oil shimmers, add the lamb in batches, browning on all sides for about 5-7 minutes each. Remove the browned lamb and set it aside on a plate.
Step 2: Sauté the Aromatics
In the same pot, add the sliced onion and minced garlic. Sauté for about 3-4 minutes until they become translucent and fragrant, scraping up any browned bits stuck to the pot. This will enhance the flavor of your Irish stew with mashed potatoes. Make sure not to let the garlic brown too much, as it can become bitter.
Step 3: Combine Ingredients for the Stew
Return the browned lamb to the pot, following it with the sliced carrots, diced potatoes, and your choice of beef or lamb broth. If you're using Guinness stout, pour that in too, along with the tomato paste, thyme, parsley, and bay leaves. Stir everything together until well combined, creating a rich, flavorful mixture.
Step 4: Simmer the Stew
Bring the pot's contents to a gentle boil over medium-high heat. Once boiling, reduce the heat to low and cover the pot. Let the stew simmer for 1 ½ to 2 hours, stirring occasionally. You’ll know it’s ready when the lamb is fork-tender and the vegetables are nicely softened, filling your kitchen with a heavenly aroma.
Step 5: Cook the Potatoes for Mashing
While the stew simmers, prepare the potatoes for your creamy mashed potatoes. In a separate pot, boil the peeled and diced potatoes in salted water. Cook for about 15-20 minutes, or until they easily pierce with a fork. Drain them well to ensure your mash is smooth and not watery.
Step 6: Mash the Potatoes to Perfection
Return the drained potatoes to the pot. Add ½ cup of milk and ¼ cup of butter. Mash with a potato masher or fork until your mashed potatoes are smooth and creamy. Give them a taste and season with additional salt and freshly ground black pepper to suit your preferences, completing your comforting side for the Irish stew.
Step 7: Finalize the Stew
Once the stew has finished simmering, remove the pot from heat and discard the bay leaves. Taste the stew for seasoning, adding more salt and pepper if needed. Serve it hot, ladling generous portions into bowls alongside a lovely scoop of your fluffy mashed potatoes.
Step 8: Garnish and Serve
To add a fresh touch, sprinkle some chopped parsley over the finished dish. This final step not only adds a pop of color to your Irish stew with mashed potatoes but also enhances its flavor. Enjoy this soul-warming and hearty meal with loved ones around your dining table!

Tips for the Best Irish Stew
Sear the Lamb Well: Ensure the lamb shoulder is browned properly to develop rich flavors; don't crowd the pot and brown in batches if needed.
Use Quality Broth: A flavorful broth is crucial; homemade or a high-quality store brand makes all the difference in your Irish stew with mashed potatoes.
Check Seasoning: Always taste your stew before serving, adjusting salt and pepper as needed to elevate flavors.
Mashed Potatoes Secrets: For creamier mashed potatoes, ensure they are drained well and mashed while hot; adding butter first helps achieve that perfect consistency.
Slow Cook for Tenderness: Don’t rush the simmering process; allowing the stew to cook low and slow ensures that the lamb becomes tender and infuses the dish with deep flavor.
