Heat a large pot over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned and cooked through, about 5-7 minutes. Drain excess fat if necessary.
1 pound ground beef
Add the diced onion and minced garlic to the pot. Sauté for 3-4 minutes, stirring occasionally, until the onion becomes translucent and fragrant.
1 medium onion, 3 cloves garlic
Stir in the corn, diced tomatoes (including their juices), black beans, broth, and taco seasoning. Bring the mixture to a gentle simmer.
1 cup corn kernels, 2 cans diced tomatoes, 1 can black beans, 1 cup beef or chicken broth, 2 tablespoons taco seasoning
Reduce the heat to low and let the soup simmer uncovered for 20-25 minutes, stirring occasionally, until the flavors meld and the soup thickens slightly.
Taste the soup and adjust seasoning if needed. Ladle the hot soup into bowls, sprinkle with shredded cheese and chopped cilantro for freshness.
1 cup shredded cheese, to taste fresh cilantro
Serve immediately, enjoying the hearty, flavorful stew with a tortilla chip or crusty bread if desired.
