Preheat your oven to 375°F (190°C) and grease a medium casserole dish with olive oil.
In a medium saucepan, combine the rinsed quinoa and vegetable broth (or water) and bring to a boil. Reduce heat to low, cover, and simmer for 15 minutes or until the quinoa is fluffy and the water is absorbed.
In a large mixing bowl, combine the cooked quinoa, halved cherry tomatoes, chopped basil, minced garlic, and both mozzarella and Parmesan cheeses.
Drizzle with olive oil, add oregano, and season with salt and pepper to taste. Mix well until the ingredients are thoroughly combined.
Transfer the quinoa mixture into the greased casserole dish, spreading it evenly. Sprinkle any remaining cheese on top for an extra cheesy crust.
Bake in the preheated oven for 25-30 minutes, until the cheese is melted and golden brown.
Remove from the oven and let it cool for a few minutes before serving. Garnish with additional fresh basil if desired.
Notes
Serve directly from the casserole dish, garnished with fresh basil and a drizzle of olive oil.
