In a large pot of salted boiling water, cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
In the same pot, over medium heat, add the ground beef (or turkey) and cook until browned, breaking it apart with a spoon, about 6-8 minutes.
Add the diced onion and minced garlic to the cooked meat. Sauté until the onion is translucent, about 3-4 minutes.
Stir in the taco seasoning and mix until evenly coated with the meat and vegetables.
Pour in the can of diced tomatoes with green chilies (with their juices) and the beef broth. Stir everything together and bring it to a simmer.
Once simmering, add the cooked macaroni, corn, and sour cream to the pot. Stir until all ingredients are well combined and heated through, about 3-5 minutes.
Sprinkle in the shredded cheddar cheese, stirring until melted and creamy. Adjust seasoning with salt and pepper as desired.
Spoon the cheesy taco pasta into bowls or onto plates. Garnish with chopped cilantro for a fresh touch.
Notes
Serve in colorful bowls and sprinkle extra cheese and cilantro on top for a vibrant look. A squeeze of lime over the top just before serving adds an exciting flavor twist!
