Step 1: Preparing the Rice

1. Rinse the rice thoroughly under cold water until the water runs clear. This removes excess starch for fluffier rice.
2. In a medium saucepan, combine the rice, chicken broth, butter, and a pinch of salt. Bring to a boil over medium-high heat.
3. Once boiling, reduce the heat to low, cover, and let it simmer for 15 minutes or until all the liquid is absorbed.
4. Remove from heat and let the rice rest, covered, for about 5 minutes. Fluff with a fork before serving.

Step 2: Cooking the Chicken

1. Season the chicken with salt and pepper.
2. In a large skillet, heat olive oil and butter over medium-high heat.
3. Add the chicken thighs and cook for about 4-5 minutes per side, until golden brown and cooked through. Remove from the skillet and set aside.

Step 3: Making the Honey Soy Garlic Sauce

1. In the same skillet, add a little more butter if needed, and sauté the onion until soft, about 3 minutes.
2. Add the minced garlic and grated ginger. Cook for another 1-2 minutes until fragrant.
3. Mix in the honey, soy sauce, rice vinegar, sesame oil, ketchup (if using), and chili flakes. Stir well to combine.
4. Bring the mixture to a simmer and let it cook for 5 minutes until slightly reduced.
5. Add the cornstarch slurry (cornstarch mixed with water) to thicken the sauce, stirring continuously until it reaches the desired consistency.

Step 4: Combining Chicken with Sauce

1. Return the cooked chicken to the skillet and spoon the sauce over the chicken pieces.
2. Let the chicken simmer in the sauce for 5 minutes, ensuring each piece is well coated.

Step 5: Serving

1. Plate a portion of fluffy rice and top it with the honey garlic chicken.
2. Drizzle any remaining sauce over the dish.
3. Garnish with chopped green onions and sesame seeds for an extra burst of flavor.
