Season the chicken
Toss chicken chunks with sazón, adobo, and black pepper.
Brown the chicken
Heat olive oil in a large pot or Dutch oven. Brown chicken on both sides (doesn’t have to be cooked through). Remove and set aside.
Build the flavor base
In the same pot (using the same oil from the chicken), add carrot slices and green onion stalks. Sauté over medium-low heat for 5–6 minutes until softened and fragrant. Add garlic and cook for 1 minute more.
Toast the rice
Add the 16-oz yellow rice packet directly into the pot with the vegetables. Sauté over low–medium heat for 3–5 minutes, stirring continuously so the rice doesn’t burn.
Add liquid and seasonings
Stir in 5 cups water, tomato bouillon, bay leaf, and the drained beans. Return chicken to the pot. Bring everything to a boil.
Simmer
Once boiling, cover the pot and reduce heat to very low. Simmer for 25–30 minutes without uncovering.
Check & finish cooking
After 30 minutes, give the pot one quick stir, re-cover, and cook another 10 minutes on very low heat.
Rest & fluff
Remove from heat. Let stand uncovered for 10 minutes before serving. Fluff with a fork and enjoy.
