Classic Irish stew typically only includes potatoes, onions, carrots, and celery, but you can get creative and add other vegetables to customize it however you'd like. Here are a few suggestions:
Leeks: With a milder flavor than onions, leeks add a delicate sweetness and subtle onion flavor to the stew. Cabbage: While not traditionally included in Irish stew, cabbage can be a delicious addition, especially if you're looking to incorporate more vegetables or add a touch of sweetness to the dish. Mushrooms: Adding mushrooms to the stew can enhance its umami flavor and provide an extra layer of richness and depth. Peas: Whether fresh or frozen, peas add a pop of color and sweetness to the stew, making it even more satisfying.
