01 - In a large, deep skillet or Dutch oven, heat a splash of oil over medium heat. Add the diced onion and bell pepper, and sauté for 3-4 minutes until softened.
02 - Stir in the minced garlic and jalapeño (if using), and cook for 1 minute more until fragrant.
03 - Add the rinsed white rice, cumin, chili powder, smoked paprika, salt, and pepper to the skillet. Stir well to coat the rice and spices.
04 - Pour in the diced tomatoes with their liquid, drained and rinsed white beans, frozen corn, enchilada sauce, and vegetable broth. Stir everything together to combine.
05 - Bring the mixture to a boil, then reduce the heat to low. Cover the skillet and let it simmer for 18-20 minutes, stirring occasionally, until the rice is tender and most of the liquid has been absorbed.
06 - Remove the skillet from the heat. Stir in the sour cream and 1 cup of shredded Monterey Jack cheese until the mixture is creamy and well combined.
07 - Taste the dish and adjust salt and pepper as needed.
08 - Serve the creamy enchilada white beans and rice hot. Garnish with additional cheese, fresh cilantro, green onions, and lime wedges, if desired.
