Start by preheating your oven to 375°F (190°C) to ensure it's hot when you're ready to bake.
Rinse the bell peppers thoroughly. Carefully slice off the tops of each pepper and use a spoon to remove the seeds and membranes inside. Arrange the hollowed-out peppers standing upright in a baking dish to hold their shape during cooking.
In a large mixing bowl, combine the shredded chicken, ranch dressing, corn, black beans, half of the shredded cheddar cheese, garlic powder, onion powder, smoked paprika, and a pinch of salt and pepper. Use a spatula or wooden spoon to stir the mixture together until all ingredients are fully combined and evenly coated.
Using a spoon, generously fill each bell pepper with the ranch chicken mixture, pressing it down gently to pack it in well and ensure it fills the pepper completely.
Sprinkle the remaining cheddar cheese on top of each stuffed pepper, allowing it to melt beautifully while baking.
Cover the baking dish with aluminum foil to trap moisture and bake in your preheated oven for about 25 minutes. After this time, carefully remove the foil and continue baking for an additional 10-15 minutes, or until the peppers become tender and the cheese is golden, melted, and bubbly.
Once cooked, take the peppers out of the oven and allow them to cool slightly for a few minutes before serving, as they will be very hot.
If you like, sprinkle freshly chopped cilantro on top for a burst of color and flavor before serving.
Notes
Arrange the stuffed peppers on a large platter and drizzle with additional ranch dressing for a tasty finishing touch.
