Authentic Paleo Vietnamese Beef Pho (Phở Bò)

Ingredients

For the Toasted Spices & Aromatic Phở Broth:

• 6 cups rich grass-fed beef bone broth
• 1 large yellow onion, peeled and halved
• 3-inch piece fresh ginger root, halved lengthwise
• 4 whole star anise pods
• 1 whole cinnamon stick (cassia or Ceylon)
• 4 whole cloves and 1 tsp whole coriander seeds
• 1 black cardamom pod (lightly crushed)
• 2.5 tbsp Red Boat fish sauce (pure anchovy and sea salt, Whole30)
• 1 tbsp organic coconut aminos
• 1 tsp coarse Celtic sea salt

For the Beef & Grain-Free Noodles:

• 0.75 lb 100% grass-fed top sirloin, eye of round, or ribeye, frozen for 20 mins and shaved paper-thin
• 4 medium zucchinis, spiralized into long zoodle ribbons (or hearts of palm noodles)

For the Classic Pho Herb Platter (Toppings):

• 1 cup fresh Thai basil or sweet Italian basil leaves
• 0.5 cup fresh cilantro sprigs
• 2 scallions (green onions), thinly sliced
• 1 fresh jalapeño or bird's eye chili, thinly sliced
• 1.5 cups fresh bean sprouts (optional)
• 2 organic limes, cut into wedges
• Sriracha or chili oil (sugar-free)

Step-by-Step Instructions

1. Char Onion & Ginger (Authentic Broth Secret): Heat a heavy dry cast-iron skillet over HIGH heat. Place the halved onion and halved ginger cut-side down. Char undisturbed for 4 to 5 minutes until deeply blackened and fragrant.
2. Toast Whole Spices: In the same skillet or a small dry saucepan, add star anise pods, cinnamon stick, cloves, coriander seeds, and crushed cardamom. Toast over MEDIUM heat for 2 minutes, swirling constantly until essential oils release and spices become intensely aromatic. Transfer spices to a cheesecloth bag or metal spice infuser.
3. Simmer Bone Broth: In a large soup pot, combine the grass-fed beef bone broth, charred onion, charred ginger, toasted spice bag, fish sauce, coconut aminos, and coarse sea salt. Bring to a rolling boil, then reduce heat to LOW, cover, and simmer gently for 20 minutes so spices infuse deep flavor into the broth.
4. Prep Paper-Thin Beef: (Pro Tip): Place steak in the freezer for 20 minutes before prep to firm up. Using a very sharp chef's knife, shave the steak against the grain into paper-thin, translucent slices.
5. Assemble Soup Bowls: Divide spiralized zucchini noodles evenly among 4 large, deep soup bowls. Fan the shaved raw sirloin steak slices over the top of the zucchini noodles in a single layer. Scatter sliced scallions over the meat.
6. The Boiling Pour (Flash-Cooking Beef Invariant): Strain the simmering pho broth through a fine-mesh sieve and bring it back to a vigorous rolling boil. Ladle the boiling broth directly over the raw beef slices in each bowl. The piping-hot broth will instantly flash-cook the shaved beef to tender, pink, melt-in-your-mouth perfection in 10 seconds while gently warming the zucchini noodles.
7. Garnish & Serve: Serve immediately with a fresh herb platter of Thai basil leaves, cilantro, sliced jalapeños, lime wedges, and sugar-free chili oil. Slurp hot!
