Prep and Season Chicken: Trim excess fat from chicken thighs. Season with salt and pepper on both sides.
Sear Chicken: In a pot over medium-high heat, add oil and sear the chicken thighs skin-side down until lightly browned, about 4-5 minutes on each side. Set aside.
Sauté Ginger: In the same pot, add a bit more oil if needed. Sauté the ginger for about a minute to lightly brown them, bringing out their flavor.
Sauté Onion and Garlic: Add the onion and garlic. Cook until they become translucent; this maximizes their flavor.
Toast Rice and Turmeric: Add the rice and turmeric powder. Stir for a minute to lightly toast the rice.
Add Water and Seasonings: Pour in 8 cups of water, chicken base or bouillon, and fish sauce. Stir to dissolve and scrape up any fond from the bottom. Bring to a boil. Reserve 2 cups of water to add later if needed.
Add Chicken: Slice the seared chicken into bite-sized pieces, then add them to the mixture.
Simmer: Reduce heat to low, cover with a lid, and simmer for 20 minutes. Stir occasionally. The rice should reach a porridge-like texture. Add more water if needed.
Serve: Taste and adjust seasoning. You may need salt, black pepper, or a dash of fish sauce. Spoon into bowls and top with sliced scallions, soft-boiled eggs, and fried garlic. Include lemon or calamansi slices on the side for added zest.
