Sauté the onion

• Heat a little oil in a large pot.
• Sauté the onion with a pinch of salt until soft.

Brown the beef

• Add the ground beef and let it sit undisturbed to develop a nice crust.
• Break it up, then season with salt, pepper, the remaining seasonings and the garlic.

Cook the tomato paste

• Clear a space in the pan and add the tomato paste.
• Cook it directly against the hot pan until it starts to darken, then stir it into the rest.

Simmer the pasta

• Add the broth and bring everything to a simmer.
• Pour in the uncooked pasta, give it a stir, then cover and simmer, stirring occasionally, until al dente.
• Add a few splashes of broth if it starts looking dry.

Make it creamy

• Pour in the cream and add the cheeses handful by handful.
• Keep stirring until everything is super creamy and glossy.
• Taste and season with salt and pepper as needed.

Rest and serve

• Let it sit for a couple of minutes so the sauce can really cling to the pasta.
• Serve and enjoy.
