Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish.
Bring a large pot of water to a boil and blanch the broccoli florets for 2 minutes. Drain and immediately place them in an ice bath to stop the cooking process. Drain again and set aside.
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in the gluten-free flour, stirring constantly for 1 minute to create a roux.
Slowly pour in the milk while whisking continuously to ensure no lumps form. Cook for 3-4 minutes or until the mixture thickens slightly.
Stir in the garlic powder, onion powder, salt, and pepper. Remove from heat and fold in the shredded cheddar cheese and grated Parmesan. Mix until the cheese is melted and the sauce is smooth.
In the prepared casserole dish, layer the broccoli florets evenly. Pour the cheese sauce over the broccoli, ensuring it is well-coated.
In a small bowl, combine the gluten-free breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole.
Bake in the preheated oven for 25-30 minutes, or until the breadcrumbs are golden brown and the casserole is bubbling.
Remove from the oven and let it rest for 5 minutes before serving. Enjoy!
