Brown the Beef
Heat a skillet over medium-high heat with a little oil. Sear the beef chunks for 2–3 minutes per side until browned.
Add Ingredients to Crockpot
Place potatoes, carrots, celery, onion, and garlic into the crockpot. Add browned beef on top.
Add Broth and Seasonings
Pour in beef broth. Stir in tomato paste, Worcestershire sauce, paprika, thyme, salt, and black pepper.
Slow Cook
Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours until the beef is tender and potatoes are soft.
Thicken the Stew
Mix cornstarch and water in a small bowl until smooth. Stir into the crockpot during the last 20 minutes of cooking.
Garnish and Serve
Sprinkle fresh parsley on top and serve warm with bread, biscuits, or cornbread.
