Equipment

• To make your Slow Cooker Irish Beef Stew, begin by adding 1 tablespoon unsalted butter to a large sauté pan over medium heat.
• Once the butter has melted, add in the onions and leeks and season with thyme, garlic powder, salt, and pepper.
• Cook, stirring occasionally, until fragrant, about 5 minutes.
• Transfer the mixture to your slow cooker.
• Return the sauté pan to your stovetop over medium high heat and add in your remaining 1 tablespoon butter.
• Season the beef with salt and pepper, then add to the pan in batches, browning on all sides.
• Transfer the browned beef to your slow cooker.
• Add in your carrots and parsnips to the pan. Cook, stirring occasionally, for 5 minutes.
• Add 1/4 cup beef stock to the pan with the carrots and parsnips, and scrape at the bottom of the pan to loosen the browned bits.
• Transfer the mixture to your slow cooker, then pour in the remaining beef stock into the slow cooker.
• Follow with the Guinness, Worcestershire sauce, pearl barley, and potatoes, stirring to combine.
• Cover and cook on low for 8 hours.
• After 8 hours, stir in the peas and serve.
