The lamb in this delicious stew is braised in a flavorful Guinness-spiked broth until it almost falls apart. Guinness Stout’s rich flavor, a result of brewing beer from roasted unmalted barley, gives this hearty lamb-and-vegetable stew a deep, rich taste. You’ll love this amazing and satisfying recipe with tender chunks of lamb, potatoes and carrots, and no processed packets of mystery ingredients–just healthy goodness!

This Irish lamb stew recipe is easy to make and perfect for special occasions (think St Patrick’s Day!) or just a simple weeknight meal. And did we mention this is a one-pot meal? Having a dinner that comes together fast is only half the battle if it dirties every dish in the kitchen. This one-pot wonder is not only fast to prepare, it’s a snap to clean up!

Pro Tip: This recipe can easily be doubled and leftovers are easy to heat and flavorful. To speed up the preparation, cut the lamb and vegetables the night before and heat the broth on the stove or in the microwave while the lamb is browning–that will help bring the pot to pressure more quickly.
