Description

Keto Pho Soup is a low-carb adaptation of Vietnamese beef pho, featuring a rich aromatic broth, thinly sliced beef, and keto-friendly veggie “noodles.” It delivers the same authentic Southeast Asian flavor while replacing traditional rice noodles with low-carb alternatives.

Ingredients

Scale

1/2x 1x 2x 3x

For the Broth:

• 6 cups beef broth
• 1 lb beef bones (optional but recommended for deeper flavor)
• 1 large onion, halved
• 2 piece -inch fresh ginger, sliced
• 3 cloves garlic, smashed
• 2 whole star anise
• 1 cinnamon stick
• 4 whole cloves
• 1 tbsp fish sauce
• 1 tsp salt (adjust to taste)
• ½ tsp black pepper

For the Soup:

• ½ lb thinly sliced beef sirloin or flank steak
• 2 cups zucchini noodles (or shirataki noodles)
• ½ cup bean sprouts
• ¼ cup sliced red onion
• 2 green onions, sliced
• Fresh herbs: basil, cilantro, mint (¼ cup assorted)
• 1 red chili, thinly sliced
• 1 lime, cut into wedges

Instructions

1. Prepare Aromatics: Lightly char the halved onion and sliced ginger in a dry pan over medium heat for 3–4 minutes until slightly blackened—this deepens the broth flavor.
2. Build the Broth: In a large stockpot, add beef broth, bones (if using), charred onion, ginger, garlic, star anise, cinnamon stick, cloves, fish sauce, salt, and pepper. Bring to a boil over high heat.
3. Simmer: Reduce heat to low and simmer uncovered for 30 minutes. Remove bones and strain broth through a fine mesh strainer to keep it clear.
4. Prepare the Bowl: Add zucchini noodles (or shirataki noodles) to each serving bowl. Top with thinly sliced raw beef, red onion, bean sprouts, and herbs.

1. Assemble & Serve

   Pour the hot broth directly over the raw beef in each bowl—the heat will cook it instantly.
   Garnish with chili slices, extra herbs, and lime wedges. Serve hot with optional keto condiments.
