In a large skillet over medium-high heat on the stove, add in the oil and heat. Add in the beef and fry until browned on all sides. Place in the bottom of your slow cooker.
Add in the onion, garlic, carrots, sweet potatoes, celery and bay leaves.
In a large bowl or 8 cup capacity measuring glass, whisk together the remaining ingredients until combined. Pour over the vegetables and beef, then stir to combine.
Cook on low heat for 8-9 hours, or on high for 5-6. If desired, 30 minutes before serving prepare the Crockpot Dumplings according to recipe instructions.
