Cheeseburger Soup 

Preparation

1. Step 1

   Heat a large pot or Dutch oven over medium. Add the ground beef and cook, breaking it up into small pieces, until just barely pink, about 2 minutes. Using a slotted spoon, transfer to a plate and set aside; pour off any fat.

2. Step 2

   Heat the olive oil in the same pot over medium. Add the diced onion, celery, carrot, minced garlic, mustard powder, paprika and 1 teaspoon each salt and pepper and cook, stirring, for 5 minutes, until the onion is just softened and everything is fragrant.

3. Step 3

   Adjust the heat to medium-high, then stir in the broth, potatoes and reserved beef; cover to bring to a boil. Reduce heat and simmer, covered, until vegetables are just soft when pierced with a fork, 8 to 10 minutes.

4. Step 4

   Meanwhile, in a small saucepan over medium heat, melt the butter. Add the flour and whisk until light tan and fragrant, about 1 minute. Add milk and continue to whisk until thickened, making sure no lumps form, 4 to 5 minutes more.

5. Step 5

   Add the milk mixture to the pot along with the shredded Cheddar. Stir until the cheese is incorporated and the soup is fully warmed through and creamy, about 5 minutes. Taste and season with salt and pepper as needed. Keep warm over medium heat until ready to serve. Serve topped as desired, with shredded Cheddar, chopped tomatoes and scallions, crumbled bacon and sour cream. (Soup can be refrigerated for up to 5 days.)
