Fill two large pots with 10 cups of water and get them boiling over high heat.
Peel your potatoes, onions, and carrots. Chop the potatoes, onions, carrots, and celery into small pieces to speed up their cooking time. Add them to the boiling water and cook until fork-tender (about 30 minutes).
1 large potato, 1 large onion, 4 large carrots, 1 rib celery
Meanwhile, in the second pot, cook your pasta to al dente, strain, and set aside in a large serving bowl.
16 ounces elbow macaroni
Once your veggies are ready, strain the water and add them to a blender or food processor. Allow them to cool for a couple of minutes to avoid too much steam while blending. Add your nutritional yeast, vegan butter, garlic, salt, and pepper to the food processor or blender and blend on high until smooth (about 2-3 minutes).
¼ cup nutritional yeast, 2 tablespoons plant-based butter, 2 cloves garlic, peeled, 1 teaspoon salt, ¼ teaspoon pepper
Add your sauce to your pasta and stir to coat.
Drizzle on your truffle oil and enjoy!
