Lay the chicken on paper towels or a clean kitchen towel. Blot excess moisture with additional paper towels or another clean towel.

In a 12-inch non-stick skillet, heat butter and vegetable oil over medium heat until the butter is fully melted. Add the chicken in a single layer without overlapping pieces. If necessary, cook in two batches. Sprinkle chicken with salt and pepper. Cook for 3-4 minutes on one side until easily released from the pan and lightly browned. Flip and cook the other side until a few brown spots appear.

Pour the adobo sauce over the chicken in the skillet. Turn the heat slightly higher and bring the sauce to a boil.

Cover the skillet, reduce the heat to medium-low, and cook for 20 minutes, or until the chicken is cooked through. Check doneness by cutting into the thickest piece—there should be no pink—or using an instant-read thermometer (internal temperature should register 165°F/73.8°C).
