  • 8 oz shirataki noodles
  • 2 Tbsp olive oil
  • 1 large onion chopped
  • 2-5 cloves garlic mashed and then minced
  • 2 10 oz cans Rotel diced tomatoes with green chiles
  • 2 Tbsp tomato paste
  • 5-6 cups water
  • 2 tsp chicken bouillon base I use Better Than Bouillon
  • 3/4 tsp salt or to taste
  • 2 med limes optional


  • Empty shirataki package of noodles into a strainer, rinse and let sit while preparing the broth.  
  • In a large pot or dutch oven, heat 2 Tbsp oil over med-high heat.  Add chopped onion and saute for 5-8 minutes until caramelized.  Add garlic and stir in for 30 seconds.
  • Add the 2 cans of diced tomatoes and 2 Tbsp tomato paste.  Stir together.  Add drained shirataki noodles and stir into the tomato base for a minute or two.  Add water to cover (5-6 cups) and 2 tsp bouillon base and salt to taste.
  • Bring mixture to a boil and then reduce heat and simmer soup for 10-15 minutes or until heated through.  I took my plastic spatula and cut the noodles while they were simmering.  Alternatively you could leave them long or cut them ahead of time. 
  • Serve with lime squeezes and a cold beverage.  Buen Provecho!
