Essential Ingredients

• Aromatics: Onions, garlic, and shallots add depth to the broth.
• Spices: Warm spices such as cinnamon, cardamom, and star anise enrich the flavor profile.

3. Add the garlic, onion, ginger, turmeric, paprika, cayenne, and salt. Grind until a smooth paste forms.
4. Heat the vegetable oil in a pan over medium heat and cook the paste for 1–2 minutes, stirring constantly until fragrant.

Instant Pot Khao Soi (Pressure-Cooked Chicken)

For a faster version of our Khao Soi, try this Instant Pot method that uses pressure cooking to quickly tenderize chicken thighs or drumsticks while infusing the broth with rich, authentic flavors.

Ingredients:

• 1 tablespoon curry paste
• 2 cups coconut milk
• 1 cup chicken broth
• ½ cup water
• 1 tablespoon fish sauce
• 1 tablespoon brown sugar
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 1 lb chicken thighs or drumsticks
• Aromatics:
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 1 shallot, sliced
• 2 cups egg noodles
• Fresh herbs (cilantro, basil, or mint) for garnish

Instructions:

Sauté Aromatics:
Press the “Sauté” button on your Instant Pot. Add a splash of oil and sauté the chopped onion, garlic, and shallot until softened (about 2–3 minutes).

Develop the Curry Paste:
Add the curry paste to the pot and continue to sauté for another 1–2 minutes until it becomes fragrant.

Build the Broth:
Stir in the coconut milk, chicken broth, and water. Then add the fish sauce, brown sugar, salt, and black pepper.

Pressure Cook the Chicken:
Place the chicken thighs or drumsticks into the pot, ensuring they are mostly submerged in the liquid. Cancel the Sauté mode, secure the Instant Pot lid, and set it to Pressure Cook (Manual) on high for 10 minutes.

Release Pressure:
Once the cooking cycle finishes, allow a natural pressure release for 5 minutes, then carefully quick-release any remaining pressure.

Shred the Chicken:
Remove the chicken from the pot. Shred or chop it into bite-sized pieces and return it to the broth.

Cook the Noodles:
Switch the Instant Pot back to Sauté mode. Add the egg noodles and cook for about 2 minutes, stirring gently until they are just tender.

Finish & Serve:
Taste the broth and adjust the seasoning if necessary. Ladle the soup into bowls, garnish with fresh herbs (and a squeeze of lime if desired), and serve hot. Add the egg noodles and cook for about 2 minutes, stirring gently until they are just tender.
