This healthy fettuccine Alfredo is a lightened up version of a classic while maintaining that same comfort taste! Completely dairy free and vegan, it’s easy to meal prep and make for a crowd or family!

  • 1 tsp thyme
  • 1 tsp rosemary

  • 1/2 tsp pepper

Mushroom Fettuccine:

  6. Turn off the heat, cover, and let sit on or near the stove while you boil the pasta.
  7. In a large pot, heat directed amount of water according to the pasta you’re using and add in 1 tsp of olive oil to the water.
  8. Let the water come to a boil, then reduce the heat to cook the pasta according to the directions.
