Preheat your oven to 375°F (190°C).
Melt the butter in a skillet over medium heat. Add the diced onion and sauté until soft and translucent, about 3-4 minutes. Set aside.
In a large mixing bowl, combine the cooked rice, drained tuna, cream of mushroom soup, milk, sautéed onions, frozen peas, shredded cheddar cheese, salt, and black pepper. Mix well to combine evenly.
Grease a 9x13-inch baking dish with olive oil or non-stick cooking spray. Pour the rice and tuna mixture into the dish and spread it out evenly.
In a small bowl, mix the bread crumbs with olive oil until lightly coated. Sprinkle the bread crumbs evenly over the top of the casserole.
Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the bread crumb topping is golden brown.
Remove from the oven and let the casserole cool for a few minutes before serving. Enjoy!
