Preheat the oven to 350 degrees F (175 degrees C).
Melt butter in a large saucepan over medium heat. Add onion, bell pepper, and green onion; cook until tender, about 10 minutes. Stir in shrimp, condensed soups, and tomatoes with green chiles; bring to a boil.
Off heat, stir in rice; season with salt. Pour shrimp rice mixture into a baking dish; cover tightly with aluminum foil.
Bake in the preheated oven for 30 minutes. Remove foil, stir, and bake until bubbling, about 30 minutes more.
