Cook the Beef: In a large soup pot or Dutch oven, brown the ground beef over medium heat until fully cooked. Drain any excess grease to keep the soup rich but not oily.
Add the Flavor Base: Stir in the taco seasoning and ranch seasoning packets. Mix well to coat the beef evenly — this is where all that signature taco flavor starts to build.
Add the Vegetables and Beans: Pour in the corn, chili beans, Rotel, and diced tomatoes (do not drain). Stir everything together until well combined. The mix of beans and tomatoes creates a thick, flavorful base full of texture and color.
Simmer the Soup: Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low and let it simmer uncovered for about 20–30 minutes. Stir occasionally as the flavors meld together into one delicious, hearty soup.
Adjust to Taste: Taste the soup and adjust seasonings if needed — you can add more taco seasoning for spice or a bit of salt and pepper to balance the flavors.
Serve and Garnish: Ladle the hot taco soup into bowls. Top each serving with a spoonful of sour cream, a generous handful of shredded cheese, and crushed Red Doritos for that crispy, cheesy crunch that makes this recipe unforgettable.
