Place each chicken breast between two sheets of plastic wrap. Gently pound them with a meat mallet until they are an even thickness. This helps the chicken cook evenly and makes it easier to roll.
Season both sides of the chicken with garlic powder, onion powder, salt, and pepper. Spread softened cream cheese evenly over each breast. This layer keeps the filling creamy and flavorful.
Sprinkle shredded mozzarella generously over the cream cheese. Arrange the jalapeno slices evenly on top, adjusting the amount depending on how spicy you like it.
Starting from one end, roll the chicken tightly like a burrito. Use toothpicks to hold the shape so it doesn’t open while cooking.
Heat olive oil in a skillet over medium heat. Sear each roulade for about 2–3 minutes per side until golden brown. This step locks in the juices and adds a nice crust.
Transfer the seared roulades to a baking dish and bake in a preheated oven at 375°F (190°C) for about 25 minutes. Let them rest for 5 minutes before slicing so the juices stay inside.
