Dice the potatoes into large chunks so they hold their shape. Slice the carrots and dice the onion. Mince the garlic.
Step 3: Make the Tomato Base
In a bowl, whisk together the tomato paste, water, salt, pepper, garlic, onion powder, and dried oregano until smooth.
Step 4: Assemble the Crockpot
Add the cooked ground beef, potatoes, carrots, onion, and tomato mixture to the slow cooker. Stir everything together until well combined.
Step 5: Slow Cook
Cover and cook on LOW for 7 hours. Avoid lifting the lid—every peek releases heat and slows cooking.
Step 6: Serve & Enjoy
Ladle into bowls and top with shredded cheddar cheese if desired. Serve with warm bread for dipping into that rich, savory broth.
