Clean, peel, and dice the carrots and potatoes.
Place the potatoes and carrots into individual stock pots with water.
Bring to boil and continue cooking until both are soft.
Remove from heat, drain, and rinse with cold water to cool the vegetables before adding to the blender.
Add the cooled potatoes and carrots to a high speed blender.
Continue by adding the water, oil, lemon juice, salt, onion, and garlic powder.
Blend until smooth, set aside.
After 30 minutes, test the baked spaghetti to see if the noodles are soft.
If the noodles are not soft, return to the oven, continue to bake until the noodles are soft, checking every 10 minutes.
Once the noodles are soft, remove from the oven.
If not adding cheese, let the baked spaghetti set for about 10 minutes before serving.
Pour or sprinkle the vegan cheese on top and place back into the oven for 5 to 10 minutes or until the cheese is melted.
Remove from the oven after the cheese has melted, let the dish set for about 10 minutes before cutting into to serve.
Serve with your favorite vegetables and enjoy!
