Preheat your oven to 375°F (190°C).
In a large oven-safe skillet, heat the olive oil over medium-high heat. Season the chicken breasts with garlic powder, onion powder, smoked paprika, salt, and pepper.
Add the seasoned chicken to the skillet and sear for about 4-5 minutes on each side until golden brown. Remove the chicken from the skillet and set aside.
In the same skillet, add the sliced jalapeños, corn, and diced tomatoes. Stir to combine and cook for 2-3 minutes until heated through.
Reduce the heat to low, then stir in the heavy cream and half of the shredded cheddar cheese until melted and combined.
Return the chicken to the skillet, spooning some of the creamy mixture over the top. Sprinkle the remaining cheese on top of the chicken.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through (internal temperature should reach 165°F).
Remove from the oven and let it rest for a few minutes. Garnish with chopped cilantro if desired before serving.
