Heat a large pot over medium. Add oil, butter, onion and garlic. Stir for 1 minute until fragrant. Add ground beef, break up into pieces and cook until brown, about 6 minutes.

Add salt, black pepper, smoked paprika, oregano and cayenne pepper. Stir in tomato paste and cook for 1 minute.

Add pasta and pour in broth. Stir to combine, bring to a boil, then reduce heat to medium low and simmer, covered, for about 6-8 minutes, or until pasta is al dente. Stir occasionally.

Meanwhile, grate the cheddar cheese and chop the parsley if using.

Pour in half-and-half and add cheddar. Stir until the cheese is melted and cook for 1-2 minutes until slightly thickened. Taste and adjust salt. Finish off with parsley. Serve!
