Step 1

Heat a large pot over medium heat, add the olive oil and heat through. Add the onion and sauté until the onion is soft and translucent, about 6 minutes. Add the garlic and continue to sauté until the garlic is fragrant, about 30 seconds.

Step 2

Add the ground beef and cook, breaking it up with a wooden spoon until the meat is browned, about 8 minutes. Season with salt and pepper.

Step 3

Stir in the tomato paste and chili powder.

Step 4

Add the beef stock and bring to a boil. Add the pasta and cook, stirring occasionally, until the pasta is al dente, about 8 to 10 minutes (the cooking time may differ depending on the pasta shape).

Step 5

Remove from heat and stir in the cream, Cheddar cheese and half the chives, stirring until the cheese has melted.

Step 6

Ladle into bowls and serve topped with the remaining chives.
