In a medium saucepan, combine your preferred macaroni and enough milk to cover it, stirring over medium heat. Bring the mixture to a gentle simmer, ensuring to stir frequently for about 5 minutes until it starts bubbling.

Once the milk is bubbling, reduce the heat to low and continue to simmer for about 10 minutes, stirring constantly to prevent sticking.

Prepare the sauce by adding ripe avocados, minced garlic, lemon juice, salt, and capers to a blender. Blend on high until smooth, then add fresh basil and pulse until finely chopped.

Remove the saucepan from heat and stir in Dijon mustard and grated cheddar cheese, mixing until the cheese melts.

Gently fold the avocado sauce into the cooked pasta, then return the pot to low heat for just a minute to warm.

Spoon the Green Goddess Avocado Mac & Cheese into bowls and serve immediately while it's warm.
