Why fennel?
Fennel is a super versatile vegetable that brings a light, subtle anise-like flavor, balancing out the acidity of tomatoes. It softens up really nicely when sautéed and adds a sweet, subtle aroma that takes any pasta dish up a notch. And hey, it’s also packed with health benefits, like helping with digestion and giving you a good dose of vitamins A and C.

Instructions

Notes
- Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, add a splash of water or olive oil to revive the sauce, and warm on the stovetop or microwave.
- Be sure to cook it al dente so it retains its texture when mixed with the sauce.
- Reserved pasta water is your best friend! The starchy water helps to bind the sauce to the pasta, making the dish extra creamy and delicious.
