Prepare the Ingredients
Dice the potatoes into bite-sized pieces for even cooking.
Chop the onion and mince the garlic.
Cook the Ground Beef
In a skillet over medium heat, brown the ground beef, breaking it into small pieces as it cooks.
Add the chopped onion and minced garlic, sautéing until the onion is translucent and fragrant.
Drain excess grease and transfer the mixture to your crock pot.
Assemble the Soup
Add the diced potatoes, beef broth, cream of mushroom soup, dried thyme, and parsley to the crock pot.
Season with salt and pepper to taste. Stir to combine.
Cook the Soup
Cover and cook on low for 6–8 hours or high for 3–4 hours.
The potatoes should be tender, and the flavors will meld beautifully as the soup simmers.
Add the Creamy Elements
About 30 minutes before serving, stir in the milk or half-and-half.
Optional: Add sour cream for an extra creamy texture.
Allow the soup to warm through without boiling.
Serve and Enjoy
Ladle the soup into bowls.
Garnish with shredded cheddar cheese, fresh parsley, or a dollop of sour cream if desired.
Pair with crusty bread or a green salad for a complete meal.
