In a large pot of boiling salted water, cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, add ground turkey or beef. Cook until browned, breaking it apart with a wooden spoon (about 5-7 minutes). Drain any excess fat.
Add chopped onions and diced bell peppers to the skillet with the meat. Sauté for about 3-4 minutes until the vegetables are soft. Add minced garlic and cook for another minute until fragrant.
Sprinkle taco seasoning over the meat and vegetable mixture. Stir in the diced tomatoes (including juices) and corn kernels. Let it simmer for about 5 minutes to combine the flavors.
Add the cooked macaroni to the skillet with the meat mixture. Stir until well combined.
Reduce the heat to low, then stir in the sour cream and half of the shredded cheddar cheese. Mix until the cheese is melted and everything is creamy and heated through.
Taste and adjust seasoning with salt and pepper.
Spoon the cheesy taco pasta into bowls and top with the remaining cheddar cheese.
Sprinkle with chopped cilantro or green onions for extra flavor.
Notes
Serve in vibrant bowls and sprinkle extra cheese and fresh herbs on top for a pop of color. Add lime wedges on the side for zest.
