Instructions
Cut the chicken thighs into small bite-sized pieces. If using frozen chicken, no need to fully thaw – just enough to make cutting manageable. Set the chicken aside.
Roughly chop the peeled ginger and onion and remove the stems from the Thai chilies.
Put the ginger, chilies, onion into a high-speed blender, along with garlic cloves and 3 to 4 tablespoons of water. Blend until completely pureed.
Turn on your Instant Pot, select sauté mode (on "normal" setting), add cooking oil, the prepared puree of aromatics and the lemongrass chunks. Sauté 3 to 4 minutes.
Add 6.5 cups of water, chicken pieces, fish sauce, glutinous white rice, regular white rice, chicken bouillon cube, ground black pepper. Give a quick mix, then turn off the sauté mode.
Now secure the lid in place, choose the pressure cook mode and cook on high pressure for 25 minutes. Then wait 10 minutes before proceeding with a quick release of pressure. Please make sure to follow the safety instructions that came with your Instant Pot.
After that, give your arroz caldo a good stir. If it’s too thick, add water in small increments until you get your preferred consistency. Let it simmer on sauté mode for a couple of minutes, and stir to prevent it from sticking to the bottom of the pot.
Remove the lemongrass chunks and serve with your preferred garnishes from the options I've shared. I usually prefer mine with a squeeze of citrus (lime, lemon, or calamansi), hard-boiled eggs and sliced green onions.
When reheating, add some water to restore the consistency.
Notes
Note A: Thai green chilies – If you have a very low spice tolerance, choose milder options like Anaheim peppers or reduce the quantity of Thai chilies. Note B: Crispy garlic – here is a good recipe if you want to make some at home.
