Fully Loaded Cheeseburger Soup
4 slices bacon, halved crosswise
1 large white onion, finely chopped
2 carrots, peeled and coarsely chopped
2 small potatoes, peeled and coarsely chopped
1 celery stalk, thinly sliced
Kosher salt and freshly ground black pepper
1 pound ground beef (90% lean)
3 cups chicken broth
2 teaspoons garlic powder
2 sesame burger buns, cut into 1-inch cubes
1 tablespoon extra-virgin olive oil
2 cups (8 ounces) shredded yellow Cheddar cheese
2 teaspoons Dijon mustard
For serving: ½ cup dill pickle chips (halved if large), sour cream (optional)
Preheat oven to 350. Add the bacon to a large pot or Dutch oven. Cook over medium-high heat, flipping halfway through, until browned and crisp, 5 to 7 minutes. Transfer the bacon to a paper towel–lined plate, leaving the drippings in the pot. Measure out 2 tablespoons of the onion and set aside for garnish. Add the remaining onion to the pot along with the carrots, potatoes, and celery. Add a pinch of salt and cook, scraping up the browned bits and stirring just once or twice, until the vegetables are browned in spots, 3 to 5 minutes. Add the ground beef and 1 teaspoon each salt and pepper. Stir to combine with the vegetables, then press into an even layer that fills the pot (like one big patty!). Cook, undisturbed, until browned underneath, 6 to 8 minutes. Break up the beef into small pieces. Add the broth and garlic powder. Bring to a simmer over medium heat and cook, stirring occasionally, until the flavors have developed and the vegetables are tender, 20 to 25 minutes. While the soup simmers, toss the cubed buns with the olive oil on a sheet pan. Bake until the croutons are crisp and golden brown, 5 to 7 minutes. Remove the soup from the heat. Measure out ½ cup of the Cheddar and set aside for garnish. Stir the remaining 1½ cups cheese and all the mustard into the soup. Season to taste with salt and pepper. Crumble the bacon. Serve the soup topped with the bacon bits, reserved onion, reserved Cheddar, croutons, pickles, and sour cream (if using).
