Irish Beef Sirloin with Mac and Cheese

Remove the sirloin from the fridge and let it come to room temperature. Meanwhile, preheat the oven to 200°C (fan-assisted mode) and bring a pot of water to a boil.

Add the pasta to the hot, well-salted water and cook over high heat for 7-8 minutes, until al dente.

Once cooked, drain, but reserve one cup of starchy pasta water.
