01 - Heat a large skillet over medium heat. Add ground beef and cook, breaking it up with a wooden spoon, until browned. Stir in diced onion and cook until translucent. Add minced garlic and sauté until fragrant.
02 - Pour in crushed tomatoes and beef broth. Sprinkle in chili powder, cumin, smoked paprika, salt, and black pepper. Stir thoroughly to combine.
03 - Stir in uncooked macaroni, black beans, and corn. Bring to a gentle boil, then reduce heat to low. Cover and simmer for 12–15 minutes, stirring occasionally, until pasta is tender and most of the liquid is absorbed.
04 - Remove skillet from heat. Sprinkle shredded cheddar cheese evenly over the pasta mixture. Cover and let sit for 2 minutes, or until the cheese is melted.
05 - Top with sour cream, chopped cilantro, and sliced jalapeño as desired. Serve immediately.
