Cut chicken into 1-inch cubes, pat dry, and toss with water and taco seasoning until evenly coated.
Heat olive oil in a large oven-safe skillet over medium-high heat. Sear chicken in a single layer for 6-8 minutes until golden brown and cooked through (165°F). Transfer to a plate and set aside.
Reduce heat to medium. In the same skillet, add half-and-half, rice, warmed queso blanco dip, salsa, and chicken broth. Stir until smooth and bring to a boil.
Reduce heat to low, cover tightly, and simmer undisturbed for 5 minutes (instant rice) or 18-20 minutes (long-grain rice) until rice is tender and liquid is absorbed.
Remove from heat and stir in drained Rotel tomatoes, diced green chiles, pico de gallo, and fresh cilantro until well distributed.
Nestle reserved chicken into the rice mixture and sprinkle Mexican blend cheese evenly over the top.
Broil on high for 3-5 minutes until cheese is melted and bubbly. Alternatively, cover and heat on low for 2-3 minutes to melt the cheese.
Garnish with fresh cilantro, sour cream, sliced jalapeños, and lime wedges. Serve directly from the skillet.
