Preheat the oven to 425 F.
Cook the bacon until crispy, transfer to a plate lined with a paper towel, and crumble.
Steam the broccoli until cooked but still firm.
Make the creamy sauce: mix the sour cream, mayo, garlic powder, onion powder, dried parsley, salt, and pepper.
In a large bowl, combine the broccoli florets, creamy sauce, crumbled bacon, chopped chives, and half of the shredded Colby-Monterey Jack cheese.
Spoon the mixture into an 8x8-inch baking dish, top with the rest of the shredded cheese, and bake for 20 mins. Serve hot.
