Low Carb Vietnamese Pho Soup: A Flavorful Journey

The first time I tasted authentic Vietnamese Pho, it was a revelation. The fragrant broth, the delicate rice noodles, the tender beef – it was a symphony of flavors that transported me to a bustling street corner in Hanoi, even though I was sitting in a small cafe halfway across the world. I fell in love instantly, and the only thing that kept me from enjoying it more often was the high carb count of the traditional rice noodles. That’s why I set out to create a low-carb version that captures the essence of this incredible soup without the guilt. This recipe is the result of countless experiments, and while it may not be exactly the same as the original, it’s a delicious and satisfying way to enjoy the flavors of Pho while staying true to your low-carb goals. Add some no-carb noodles if you like the texture, but even without it’s a deeply flavorful and satisfying soup.

Ingredients

Homemade Broth:

• 4 cups good quality chicken broth (or homemade)
• 1 star anise (or substitute 1/4 teaspoon anise seeds, fennel seeds, or caraway seeds for a similar flavor)
• 1 cinnamon stick (optional)
• 1 teaspoon garlic, minced
• 1 teaspoon minced fresh ginger
• 2 teaspoons soy sauce
• 1⁄2 teaspoon sesame oil
• 1⁄8 teaspoon crushed red pepper flakes (optional)

Pho Soup:

• 6 ounces sirloin steak (Slice very thin across the grain)
• 10 medium frozen shrimp (fresh is good, too)
• 1⁄4 medium white onion (thinly sliced)
• 4 leaves bok choy (optional)
• 1 green onion (sliced into little rounds)
• 1⁄4 cup basil (2 fresh sprigs) or 1/4 cup mint leaf (2 fresh sprigs)
• 1 cup bean sprouts
• 1 small lime (to squeeze over soup)

Equipment Needed

• Large saucepan
• Strainer
• Cutting board
• Knife

Instructions

1. To begin, combine all of the broth ingredients—the chicken broth, star anise, cinnamon stick (if using), minced garlic, minced fresh ginger, soy sauce, sesame oil, and crushed red pepper flakes (if using)—into a large saucepan.

2. Bring the mixture to a boil over high heat. Once boiling, reduce the heat to medium-low and allow the broth to simmer gently for approximately 15 minutes. This simmering process allows the flavors to meld together beautifully, creating a rich and aromatic base for your Pho.

3. After simmering, pour the broth through a strainer to remove and discard the solids (star anise, cinnamon stick, ginger, and garlic). This ensures a clear and smooth broth. Return the strained broth to the saucepan.

4. Bring the strained broth to another boil. Add the thinly sliced white onion and bok choy (if using) to the boiling broth. Cook just until the bok choy is limp, which should take approximately 2 minutes.

5. Next, add the thinly sliced sirloin steak and the shrimp to the boiling broth. Cook very briefly, just until the steak is medium-rare and the shrimp is heated through and cooked. This should only take a minute or two, as you want to avoid overcooking the steak and shrimp.

6. Once the steak and shrimp are cooked to your liking, turn off the heat. Immediately add the sliced green onions to the soup.

7. Pour the soup into two large soup bowls.

8. Allow everyone to add their own fresh bean sprouts and basil (or mint) leaves to taste. Cut the lime into quarters and squeeze over each bowl to taste. You can also add a little red chili sauce (from the Asian food aisle) if you like a bit of heat.

Expert Tips & Tricks

• Broth is key: The quality of your broth will greatly impact the overall flavor of your Pho. If you have the time, making your own chicken broth from scratch is highly recommended. However, a good quality store-bought broth will also work.
• Thinly sliced meat: Slicing the steak as thinly as possible is crucial for ensuring it cooks quickly and remains tender in the hot broth. Partially freezing the steak for about 30 minutes before slicing can make it easier to achieve thin, even slices.
• Don’t overcook: Overcooking the steak and shrimp will result in a tough and rubbery texture. Be sure to cook them briefly, just until they are cooked through.
• Spice it up: If you enjoy a spicier flavor, consider adding a pinch of extra crushed red pepper flakes or a dash of your favorite chili sauce to the broth.
• Consider adding a tablespoon of fish sauce to the broth for that authentic Pho taste. It does have some carbs, so make sure it works in your overall plan for the day.

Serving & Storage Suggestions

Serve your low-carb Pho immediately while it’s hot and the flavors are fresh. Garnish generously with bean sprouts, fresh herbs, and a squeeze of lime.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop or in the microwave until heated through. Be careful not to overcook the steak and shrimp when reheating. It is not recommended to freeze this soup, as the texture of the steak and shrimp may deteriorate upon thawing.
