Preheat the oven to 375 degrees F. Heat the butter in a skillet over medium-high heat. Add the onion and curry powder; cook, stirring occasionally, until onion softens, about 5 minutes. Scrape the curried onions into a 9-by-13 baking dish; stir in the soup, 1 1/3 cups water, rice, tuna and pepper. Cover with foil.
Bake until rice is cooked and the casserole has begun to turn golden, about 40 minutes.
Remove from oven; raise the temperature to 450 degrees F. Remove foil from casserole. Spread cheese over the top of casserole; return to the oven. Cook until cheese begins to melt, about 5 minutes.
