Introduction

There are few dishes as soul-satisfying and deeply comforting as a hearty Beef and Guinness Stew with Mashed Potatoes. This classic Irish-inspired dish is the epitome of rustic comfort food — tender chunks of slow-cooked beef simmered in a rich, dark Guinness gravy infused with carrots, onions, garlic, and herbs. The slight bitterness of the stout beer melds beautifully with the sweetness of caramelized vegetables, creating layers of flavor that deepen with every bite.

Served over a bed of buttery, creamy mashed potatoes, this stew is everything you crave on a chilly evening — cozy, nourishing, and full of old-world charm. It’s the kind of dish that tastes like it’s been simmering all day in your grandmother’s kitchen.

Why I Love This Recipe

I love this recipe because it’s comfort in a bowl — hearty, flavorful, and deeply aromatic. The Guinness not only adds complexity but also tenderizes the beef, making it melt-in-your-mouth soft. The slow-cooked sauce develops into something velvety and rich, perfect for spooning over a mound of mashed potatoes.

Every time I make this stew, it fills the house with a warm, savory aroma that feels like home. It’s perfect for Sunday dinners, St. Patrick’s Day celebrations, or any time you need a cozy, satisfying meal that nourishes both body and soul.

Why It’s a Must-Try Dish

This dish is a must-try because it perfectly represents the art of slow cooking. It takes humble ingredients — beef, beer, vegetables — and transforms them into something luxurious through time and patience. The Guinness adds a deep, malty richness you can’t achieve with broth alone, making the flavor unforgettable.

It’s also wonderfully versatile — make it ahead, freeze it, or serve it to guests for a dinner that feels both rustic and elegant. Once you taste the tender beef coated in the velvety gravy, you’ll understand why this is a timeless classic that never goes out of style.

• 1 large onion, chopped
• 3 carrots, peeled and sliced
• 2 celery stalks, diced
• 3 cloves garlic, minced
• 2 tbsp tomato paste
• 1 (11 oz / 330 ml) can of Guinness stout beer
• 2 cups beef broth (low sodium)
• 2 tsp Worcestershire sauce
• 2 sprigs fresh thyme (or 1 tsp dried thyme)
• 2 bay leaves
• 1 tsp brown sugar (optional, to balance the stout’s bitterness)
• 1 cup frozen peas (added at the end for color and freshness)

For the Mashed Potatoes:

• 2 lbs (900 g) potatoes (Yukon Gold or Russet), peeled and cubed
• 4 tbsp butter
• ½ cup whole milk (or cream, for extra richness)
• Salt and pepper, to taste

Step-by-Step Preparation Method

Step 1: Prepare and Brown the Beef

1. Pat the beef cubes dry with paper towels — this ensures a good sear.
2. Season generously with salt and pepper, then dust lightly with flour.
3. Heat 1 tbsp olive oil in a large heavy pot or Dutch oven over medium-high heat.
4. Brown the beef in batches (do not overcrowd the pan) until all sides are golden.
5. Remove browned beef to a plate and set aside.

Step 2: Sauté the Aromatics

1. In the same pot, add the remaining 1 tbsp olive oil.
2. Add onion, carrots, and celery. Sauté for 5 minutes, until softened.
3. Add minced garlic and cook for another 1 minute until fragrant.
4. Stir in tomato paste and cook for 1–2 minutes to caramelize slightly.

Step 3: Deglaze and Build the Base

1. Pour in the Guinness stout, scraping up browned bits from the bottom of the pot.
2. Bring to a simmer and let it cook for 5 minutes to reduce slightly.
3. Add the browned beef back to the pot along with any juices.
4. Stir in beef broth, Worcestershire sauce, thyme, bay leaves, and brown sugar (if using).

Step 4: Simmer the Stew

1. Bring everything to a gentle simmer.
2. Cover and cook on low heat for 2 to 2½ hours, stirring occasionally.
3. The stew is ready when the beef is fork-tender and the sauce has thickened.
4. In the last 10 minutes, add the frozen peas and cook until warmed through.
5. Taste and adjust seasoning with salt and pepper.

Step 5: Make the Mashed Potatoes

1. While the stew is simmering, boil potatoes in salted water for 15–20 minutes until tender.
2. Drain and mash with butter and milk (or cream) until smooth and fluffy.
3. Season to taste with salt and pepper.

Step 6: Serve

1. Spoon a generous mound of mashed potatoes onto a plate or bowl.
2. Ladle the rich beef and Guinness stew over the top.
3. Garnish with fresh parsley if desired.
4. Serve warm with a slice of crusty bread to mop up the sauce.

How to Serve

Serve this hearty stew piping hot, over creamy mashed potatoes or buttered noodles.

• For gatherings: Present it in a large Dutch oven or casserole dish.
• For a rustic touch: Pair with warm Irish soda bread or a pint of Guinness.
• For freshness: Add a side of green beans, kale, or roasted Brussels sprouts.

This dish is perfect for cozy nights in, holiday dinners, or casual weekend meals.

Recipe Tips

• Brown the beef properly: This step is key to building rich flavor. Don’t rush it.
• Don’t skip the Guinness: It’s what gives the stew its signature deep flavor.
• Simmer slowly: Low and slow cooking transforms tough beef into tender perfection.
• Thicken if needed: If the sauce is too thin, simmer uncovered for the last 15 minutes.
• Use Yukon Gold potatoes: They give the mashed potatoes a creamy, buttery texture.

Recipe Variations

1. Slow Cooker Version:
   • Brown the beef and veggies first, then transfer everything to a slow cooker.
   • Add Guinness, broth, and seasonings. Cook on LOW for 7–8 hours or HIGH for 4–5 hours.
2. Instant Pot Version:
   • Use the sauté setting to brown the beef and veggies.
   • Add liquids and cook on High Pressure for 35 minutes, then natural release for 10.
3. With Bacon:
   • Fry diced bacon before browning beef. Use bacon fat to sauté vegetables — adds a smoky depth.
4. With Mushrooms:
   • Add sliced mushrooms during the last 30 minutes for an earthy twist.
5. Guinness Pie:
   • Use leftover stew as filling for a steak and Guinness pie, topped with puff pastry.

Freezing and Storage

• Refrigeration: Store in an airtight container for up to 4 days.
• Freezing: Freeze cooled stew (without potatoes) for up to 3 months.
• Thawing: Defrost overnight in the fridge.
• Reheating: Warm on the stove over low heat or in the microwave until piping hot.
• Mashed Potatoes: Best enjoyed fresh, but can be frozen separately and reheated with a splash of milk.

Special Equipment Needed

• Large heavy-bottomed pot or Dutch oven
• Wooden spoon or spatula
• Potato masher or ricer
• Sharp knife and cutting board

Frequently Asked Questions (FAQ)

Q1: Can I use another beer instead of Guinness?
Yes — use any dark stout or porter. Avoid light beers, as they won’t provide the same depth.

Q2: Can I make this recipe without beer?
Absolutely! Substitute with extra beef broth plus 1 tablespoon of balsamic vinegar for richness.

Q3: What’s the best cut of beef to use?
Beef chuck is ideal — it’s affordable, marbled, and becomes tender with long cooking.

Q4: Can I make it ahead of time?
Yes! In fact, it tastes even better the next day as the flavors meld beautifully.

Q5: How can I thicken the stew naturally?
Let it simmer uncovered near the end, or mash a few pieces of potato or carrot directly into the sauce.
