Pho Ga Recipe Instant Pot: Fragrant Vietnamese Chicken Noodle Soup

This Instant Pot version captures all the aromatic depth of traditional Vietnamese chicken noodle soup in a fraction of the time. The pressure cooker extracts rich, complex flavors from simple ingredients, creating a broth that rivals hours of stovetop simmering.

What makes this recipe special is its balance of fragrant spices and tender chicken, all ready in under an hour. Star anise, cinnamon, and charred onion form the foundation of that signature pho aroma while keeping the process straightforward.

You’ll end up with a bowl of savory broth filled with succulent chicken, rice noodles, and fresh herbs. The result is a comforting, restaurant-quality soup that’s perfect for weeknight dinners or when you need a warming meal.

Serve with lime wedges, bean sprouts, and Thai basil for an authentic touch. Here’s how to make it.

Ingredients for Pho Ga Recipe Instant Pot

Fragrant spices and tender chicken create this aromatic soup with minimal effort.

The spices are non-negotiable for authentic flavor. Star anise, cinnamon, and cloves should be whole—not ground—to infuse the broth without bitterness. Look for them in the international aisle or Asian markets (they’re cheaper and fresher there). The chicken thighs stay juicier than breasts during pressure cooking. For charring the onion, use an open flame or broil in the oven until blackened (worth the extra minute).

No fish sauce? Soy sauce plus a pinch of sugar works in a pinch, though the depth won’t be the same. Vegetable broth can replace chicken broth (use low-sodium to control salt). For the noodles, banh pho are ideal, but any flat rice noodle does the trick. Thai basil is key—regular basil lacks the anise-like note. If you can’t find it, add a splash of anise extract to the broth.

Broth keeps 4-5 days refrigerated or 6 months frozen. Store noodles separately to prevent sogginess. The charred onion and spices can be prepped ahead—just add to the pot when ready. Reheat broth gently to preserve the aromatic oils (don’t boil).

Step-by-Step Instructions for Fragrant Vietnamese Chicken Noodle Soup

This method delivers authentic flavor with minimal effort and maximum control over the process.

Step 1: Char the Onion and Ginger

Turn your Instant Pot to the Sauté function on Normal heat. Cut the yellow onion in half and place both halves cut-side down in the pot. Cook for 8-10 minutes until the surfaces are deeply charred black and blistered. This adds crucial depth to your broth—don’t skip the char.

Add the 3 oz fresh ginger slices to the pot and char for 3-4 minutes until fragrant and slightly blackened in spots. Remove both and set aside. The fond left in the pot will dissolve into your broth, intensifying the flavor.

Step 2: Build the Aromatic Broth Base

Pour in 1 cup of the chicken broth and use a wooden spoon to deglaze the pot, scraping up all the browned bits. Add the 1.5 lb chicken thighs, 2 whole star anise pods, 1 whole cinnamon stick, 3 whole cloves, 1 tbsp rock sugar, and 1 tsp sea salt. Pour in the remaining 5 cups chicken broth.

Secure the lid and set the Instant Pot to High Pressure for 10 minutes. The pressure cooker extracts the spices’ essential oils and the chicken’s collagen quickly, creating a rich, silky broth in a fraction of the traditional time.

Step 3: Shred the Chicken and Strain the Broth

When the cooking time is complete, allow a natural pressure release for 10 minutes, then quick-release any remaining pressure. Remove the chicken thighs and set aside to cool slightly. The broth should be a deep amber color with visible oil from the spices on top.

Strain the broth through a fine-mesh sieve into a large bowl to remove the spices and ginger, then return the broth to the Instant Pot. Shred the chicken using two forks—it should pull apart effortlessly. Discard the bones if using bone-in thighs.

Step 4: Cook the Rice Noodles and Assemble

Add the 8 oz rice noodles to the Instant Pot and submerge them in the hot broth. Set the Instant Pot to Sauté on Low heat and cook for 3-4 minutes until the noodles are tender but still slightly chewy. Stir in the 2 tbsp fish sauce—this is the final seasoning adjustment, so taste and add more if needed.

Divide the shredded chicken among serving bowls. Ladle the hot broth and noodles over the chicken. The noodles should be fully submerged in the fragrant broth, ready to soak up all the flavor.

Step 5: Add Fresh Garnishes and Serve

Top each bowl with 0.5 cup Thai basil leaves, 1 cup bean sprouts, and slices of jalapeño. Serve immediately with lime wedges on the side for squeezing over the soup.

The Thai basil should be added just before serving to preserve its fresh, anise-like aroma. Each bite should have a balance of rich broth, tender chicken, and the bright, fresh crunch of the garnishes. The lime adds the final acidic note that brings all the flavors together.

Dietary Considerations for This pho ga recipe instant pot

Gluten-Free Option

This recipe is naturally gluten-free as long as you use certified gluten-free fish sauce. I recommend Red Boat or Three Crabs brands. Also verify your chicken broth is labeled gluten-free, as some brands use wheat in their processing. 💪

Dairy-Free Adaptation

The dish is inherently dairy-free since traditional pho uses no milk products. Just double-check your fish sauce and chicken broth for hidden dairy. I’ve never encountered this issue, but it’s always good to confirm.

Lower Sodium Version

Use low-sodium chicken broth and reduce the fish sauce to 1 tbsp. You can boost flavor with 1 tsp coconut aminos instead. Taste before adding the final sea salt—you may not need it at all.

Vegetarian Twist

Swap chicken thighs for 1 lb mushrooms (shiitake or oyster work best). Use vegetable broth instead of chicken. Add 1 tbsp soy sauce with the fish sauce for umami depth. The spices remain the same. 🌱

Keto-Friendly Adjustments

Replace rice noodles with shirataki noodles or zucchini noodles. Reduce the rock sugar to ½ tsp or eliminate it. The broth and chicken remain perfectly keto-compliant as written.

Allergen Awareness

The primary allergens here are fish (in fish sauce) and potentially soy (in some broths). For fish allergies, substitute coconut aminos. For soy allergies, ensure your broth is soy-free. Always check labels carefully.
