This Cheeseburger Soup is thick, hearty and loaded with ground beef, potatoes, veggies and plenty of cheese! Make it on the stovetop or in the slow cooker.
In a large pot or Dutch oven over medium-high heat, cook the beef and onion for about 5 minutes, stirring often, until the beef is browned. If there’s a lot of excess fat, you can drain some of it.
Add the carrots and celery and cook about 5 minutes, until slightly softened.
Stir in the garlic, salt, parsley, mustard, and pepper and cook for 1 minute.
Add the broth and potatoes. Bring to a simmer then reduce the heat to medium-low, cover and cook for 12 to 15 minutes, until the potatoes and carrots are tender.
In a small bowl, whisk together the half-and-half and cornstarch and add it to the soup along with the Cheddar.
Reduce the heat to low and cook, stirring, until thickened, about 2 to 3 minutes.
Taste and adjust seasonings as desired before serving.
