Full of rich and savory flavor, this Low Carb Asian Noodle Soup is inspired by the beautiful bowls of pho served at our local Vietnamese restaurant.

As much as we love the real deal, the rice noodles aren’t low carb so we’ve swapped them out for zucchini noodles in this recipe! Plus, we love one-pot recipes with very little clean-up!

Ingredients and Variations

BROTH – A great zucchini noodle bowl recipe starts with a great broth! Find pre-made pho broth at your local market.

VEGETABLES – Bean sprouts give the soup crunch and green onions provide color but feel free to add bok choy, mushrooms, or snow peas.

MEAT – Thin slices of beef, or shredded chicken, and even cubes of tofu can be used! If using thinly sliced chicken, it will need to simmer along with the zoodles to ensure it’s cooked through.

GARNISHES – This is the fun part! Whole basil leaves, mint leaves, slices of jalapeno, cilantro, and lime wedges give this low carb Asian beef noodle soup its signature look.
