Pho Soup Recipe Instant Pot: Fragrant Broth and Tender Noodles in One Hour

Traditional pho takes hours to develop its signature depth, but this Instant Pot version delivers fragrant broth and tender results in just one hour. The pressure cooker extracts rich beef and spice flavors that normally require all-day simmering.

I’ve streamlined the process without sacrificing authenticity—char the onions and ginger first for that essential smoky base, then let the Instant Pot work its magic. Star anise, cinnamon, and cloves infuse the broth with complex aromatics.

What emerges is a deeply flavored broth with tender slices of beef and silky rice noodles. The herbs stay vibrant, and the meat remains perfectly succulent, not tough.

Top with fresh cilantro, bean sprouts, and a squeeze of lime for the full experience. This method makes restaurant-quality pho accessible any night of the week.

Ingredients for Pho Soup Recipe Instant Pot

Authentic spices and quality beef create deeply aromatic broth and perfectly tender results.

The beef chuck roast is essential for the right texture—look for well-marbled pieces at Whole Foods or a trusted butcher. Char the onion and ginger first for that signature smoky base. Star anise, cinnamon, and cloves should be toasted briefly to release their oils. Asian markets often carry the best selection of these whole spices at reasonable prices.

No rock sugar? Granulated or brown sugar works in a pinch. Fish sauce is non-negotiable for authenticity, but coconut aminos can substitute for dietary needs. For the broth, homemade beef stock deepens flavor, but store-bought works too—just choose low-sodium. The rice noodles must be pho-style (flat and wide), not thin vermicelli.

Broth stays fresh for 4-5 days refrigerated or freezes beautifully for 3 months. Store spices in airtight containers away from light. Fresh herbs like cilantro and bean sprouts should be prepped just before serving to maintain their crisp texture and vibrant color.

Step-by-Step Instructions for Pho Soup Instant Pot

This streamlined method delivers deeply aromatic broth and perfectly tender beef in record time.

Step 1: Char the Aromatics for Depth

Heat your Instant Pot to the sauté function on high. Place the halved yellow onion and halved fresh ginger cut-side down in the pot. Allow them to char for 5-7 minutes until deeply blackened in spots—this caramelization builds the complex, smoky backbone of your broth.

Don’t rush this step. The charred edges should look nearly burnt, which might seem extreme, but this is the traditional technique that gives authentic pho its distinctive depth. Remove the aromatics once properly charred and set aside.

Step 2: Toast the Spices and Build the Broth

Return the Instant Pot to sauté mode and add the 2 whole star anise pods, 1 cinnamon stick, and 4 whole cloves. Toast for 1-2 minutes until fragrant—just until you smell their warm, pungent aroma.

Add the charred yellow onion and fresh ginger back to the pot along with the 1 lb beef chuck roast, 8 cups beef broth, 2 tbsp fish sauce, 1 tbsp soy sauce, 1 tbsp rock sugar, and 1 tsp salt. Stir to combine and deglaze the pot, scraping up any browned bits from the bottom.

Step 3: Pressure Cook for Tender Beef

Secure the lid and set the Instant Pot to high pressure for 20 minutes. Allow for a natural pressure release of 15 minutes, then manually release any remaining pressure. This timing ensures the beef chuck roast becomes fork-tender while the spices infuse the broth with their essence.

Once safe to open, remove the beef and set it aside to cool slightly. Strain the broth through a fine-mesh sieve to remove the spices and aromatics, pressing gently to extract all the flavor. Discard the solids—their work is done.

Step 4: Slice the Beef and Prepare the Noodles

Thinly slice the beef chuck roast against the grain into bite-sized pieces. This step is crucial for achieving the desired tenderness in the final dish. Keep the beef warm by covering it loosely with foil.

In a separate large bowl, soak the 8 oz rice noodles in hot water for 8-10 minutes until they are pliable but still slightly firm. Drain and rinse briefly with cold water to stop the cooking process. The noodles will finish cooking in the hot broth.

Step 5: Assemble and Serve

Divide the rice noodles among four serving bowls. Top each with a generous portion of the sliced beef chuck roast. Ladle the hot, strained broth over the top, ensuring each bowl is filled to your preference.

Garnish with 0.5 cup fresh cilantro, 1 cup bean sprouts, and lime wedges on the side. Serve immediately so the noodles remain tender and the beef stays warm. Each bowl should be fragrant, with visible steam rising from the surface and the beef slightly submerged in the rich, spiced broth.

Perfect Pairings for This Recipe

Herbal Garnishes

Fresh Thai basil adds a unique anise-like aroma that pairs perfectly with the star anise in your broth. I tear the leaves rather than chop them to release more essential oils. Add 1-2 sprigs per bowl just before serving for maximum fragrance. 🌿

Crunchy Toppings

For texture contrast, pile on 1 cup bean sprouts and ¼ cup thinly sliced jalapeños. The sprouts add a satisfying crunch while the jalapeños bring a subtle heat that complements the rich beef broth beautifully.

Citrus Accents

Serve with lime wedges on the side—each diner should squeeze 1-2 wedges into their bowl. The acidity brightens the deep flavors and cuts through the richness. I always keep extra limes on hand for seconds.

Sauce Pairings

Set out small dishes of hoisin sauce and sriracha for customization. A drizzle of 1 tsp hoisin adds sweetness while ½ tsp sriracha brings heat. These classic condiments elevate the experience to restaurant level. 💫

Side Dishes

Serve with Vietnamese spring rolls or gỏi cuốn for a complete meal. The light, fresh flavors of the rolls balance the hearty soup. I like to make them with shrimp and vermicelli for variety.

Beverage Choices

Pair with jasmine tea or Vietnamese iced coffee for authenticity. The floral notes of jasmine complement the spices, while the strong coffee cuts through the richness. Both options are traditional and refreshing. ☕
