This pesto butter pasta came to life during the blur of new parenthood when cooking had to be fast filling and forgiving. Over time it became our go to dinner not only for its ease but for the bright basil flavor and luscious buttery coating that turns simple noodles into something special. It is now the dish I crave on busy nights or lazy Sundays alike.
I first made this after a hectic day of parenting when energy was low and hunger was high. The simplicity won me over and the flavor made it a repeat.

Storage Tips
Store leftover pesto in an airtight jar topped with a thin layer of olive oil to preserve freshness. It will keep in the fridge for up to one week or freeze in ice cube trays for up to six months. The pasta itself is best enjoyed fresh but can be stored in the fridge for up to two days and reheated gently
Ingredient Substitutions
If pine nuts are unavailable or pricey walnuts or cashews make a great substitute. You can swap Parmesan with Pecorino for a sharper tangier finish. For a dairy free version use nutritional yeast in place of cheese and vegan butter
