I just love simple recipes that look fancy, and this creamy caramelized onion pasta definitely deserves to be in this collection. This is a simple yet elegant dish perfect for a cozy night in or entertaining guests.
Sweet, tender caramelized onions and rich, creamy cashew sauce, together with fancy-pasta is a match made in heaven.
About the pasta: Mafaldine pasta is also known as “resinate” or “frilled pasta” because of its ruffled edges resembling a queen’s crown or ocean waves. The name “Mafaldine” is a reference to Mafalda, Princess of Savoy. Mafaldine pasta is a long, flat and wide noodle that is often cut into strips about 0.5-1 inch wide. Mafaldine pasta has a slightly rough texture that allows it to hold the sauce well, making it perfect for this creamy pasta dish.
A note on Blender: Cashew cream is really easy to make in a small blender (like a Nutribullet or Ninja). If your blender container is large, you may need to double or triple the cashew cream ingredients to get it working properly and really smooth.
