Begin by preheating your oven to 375°F (190°C).

In a small bowl, mix together the salt, black pepper, onion powder, garlic powder, and paprika. Drizzle the olive oil over the chicken breasts, ensuring an even coating. Rub the seasoning mixture all over the chicken to ensure full coverage.

Next, combine the filling ingredients—chopped broccoli, shredded cheddar cheese, softened cream cheese, minced garlic, and a dash of salt and pepper—in a separate bowl, mixing thoroughly.

Carefully cut a wide pocket in each chicken breast, taking care not to slice all the way through.

Fill each chicken breast with the prepared filling mixture, packing it in gently.

In a large, oven-safe skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is hot, sear the stuffed chicken breasts on both sides until golden brown, but do not cook them completely. Depending on the size of your chicken breasts, you may need to work in two batches to avoid overcrowding the pan.

After searing, place all four stuffed breasts in the skillet and transfer it to the preheated oven.
