Preheat oven to 375F and grease a 9x13 baking dish. Steam or microwave broccoli florets for 3 minutes until bright green and just tender, then drain.
Heat olive oil in a large skillet over medium-high heat. Season chicken with salt, pepper, garlic powder, onion powder, and paprika. Cook 6-7 minutes until just cooked through.
In a large bowl, whisk together cream cheese, heavy cream, sour cream, minced garlic, and 1 cup of the cheddar until smooth.
Fold the cooked chicken and broccoli into the creamy sauce until evenly coated.
Transfer everything to the baking dish and spread evenly.
Top with the remaining cheddar, the mozzarella, and the crumbled bacon.
Bake for 22-25 minutes until bubbly and golden, then rest 5 minutes before serving.
