Preheat your oven to 375°F.
In a medium bowl, mix the cream of chicken soup, milk, garlic powder, onion powder, salt, and pepper until well combined.
In a skillet, heat the olive oil over medium heat. Add the broccoli florets and sauté for about 3-4 minutes until slightly tender. Remove from heat.
Place the chicken breasts in a baking dish and season with salt and pepper. Spread the sautéed broccoli evenly over the chicken.
Pour the soup mixture over the broccoli and chicken, ensuring everything is well coated.
Sprinkle the shredded cheddar cheese on top. If using breadcrumbs, sprinkle them over the cheese for added crunch.
Cover the baking dish with aluminum foil and bake for 25 minutes.
Remove the foil and bake for an additional 10-15 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
Let the dish rest for 5 minutes before serving.
