In a mixing bowl, combine the white beans, tomato sauce, vegetable broth, chopped onion, minced garlic, dried oregano, and dried basil. Season with salt and pepper to taste.
Pour the mixture into a baking dish and spread it out evenly.
Bake in the preheated oven for 45 minutes, or until the casserole is bubbly and the top is slightly browned.
Let it cool for a few minutes before serving. Enjoy!
