Cook the macaroni noodles according to package instructions. While the noodles are boiling start the sauce. In a large pot melt the butter, once melted saute the onion until soft and translucent. Add the flour and stir until it forms a roux (thick paste). Pour half a cup of milk into the pot and stir until well combined. Sprinkle a pinch of salt and the ground black pepper into the pot, stir well. Add the shredded cheese and a little more of the milk. Continue stirring as the cheese begins to melt. Pour the rest of the milk and continue stirring until the cheese completely melts and the cheese sauce forms. Taste again and adjust salt if necessary.
Mix the cooked and drained macaroni into the pot, be careful not to overspill. Continue mixing until all the noodles are well coated with the sauce. Serve right away.
Notes
!--Cheese is salty so hold off on adding too much salt at the beginning of cooking. Check sauce again before adding noodles to it and adjust f needed.
