Grab a heavy-bottomed pot and melt the butter over medium heat. Once it's bubbling a bit, whisk in the flour until you get a smooth paste. Let it cook for about a minute or two - this helps get rid of that raw flour taste.

Slowly pour in the half & half while whisking constantly - this is key to avoid lumps! Keep stirring as the mixture heats up for about 5-7 minutes until it starts to thicken and you see some gentle bubbling around the edges.

Turn the heat down to low and add the shredded white cheddar, salt, black pepper, and mustard powder. Keep stirring until all the cheese has melted into a smooth, velvety sauce. The mustard powder really brings out that tangy cheese flavor!

Add your cooked cavatappi pasta to the pot and fold it into the cheese sauce until every piece is coated in that creamy goodness. Give it a taste and add more seasoning if needed.

Dish up while it's still hot and watch it disappear! Nothing beats homemade mac and cheese that rivals Panera's famous version.
