Start by gathering all your ingredients and placing them on the counter for easy access. Dice the beef chuck into uniform cubes of about 1 to 1.5 inches to ensure even cooking. Peel and chop the carrots and potatoes into bite-sized pieces, and finely chop the onion. Mince the garlic cloves.
Although not compulsory, searing the beef cubes in a hot pan with a drizzle of oil before placing them in the slow cooker enhances the flavor and texture.
In your trusty slow cooker, combine the beef cubes, sliced carrots, diced potatoes, chopped onion, and minced garlic. Pour in the beef broth, tomato paste, and Worcestershire sauce. Season with salt and pepper. Stir everything together.
Set your slow cooker on low and let the stew cook for about 8 hours, or set it on high for 4 hours if you're short on time. The long, slow simmer is crucial for tender meat and a melding of flavors. About 30 minutes before completion, add the peas.
Notes
If you have leftovers, store them in an airtight container in the refrigerator for up to three days. For longer storage, freeze the stew for up to three months. Reheat gently on the stove or microwave, stirring occasionally.
