Preheat oven to 400F. Debone the chicken thighs and season well with salt and pepper. Place on a cooling rack over a foil-lined baking sheet and bake for 40 minutes.

After about 20 minutes, start preparing the filling. Chop the bacon into pieces and add them to a pan over medium heat.

Once the bacon is mostly crisped, add the jalapeños to the pan and let them cook down.

Once the jalapeños are soft and cooked, add the cream cheese, mayo, and hot sauce to the pan. Mix to combine and season to taste.

Remove the chicken from the oven and let cool slightly. Once cooled, remove the skins from the chicken.

Transfer the thighs to the bottom of a casserole dish. Spread the cream cheese mixture over them and top with the shredded cheddar and mozzarella cheeses.

Bake for 10–15 minutes. Broil for an additional 3–5 minutes to finish. Remove from the oven and let cool for about 5 minutes before serving.

Slice, serve, and enjoy!
