Preheat your oven to 350°F (175°C).

Steam or boil the cauliflower and broccoli for about 8–10 minutes until tender, then drain and cool slightly.

In a mixing bowl, combine the cream cheese, sour cream, and shredded cheese until smooth. Mix in garlic powder, onion powder, and smoked paprika.

Fold the cooked cauliflower and broccoli into the creamy mixture until well coated.

Transfer the mixture into a greased baking dish, spreading it evenly. Sprinkle additional cheese on top.

Bake in the oven for 25–30 minutes until the top is golden brown and bubbly.

Cool for 5 minutes, garnish with green onions, then serve.
