Step-by-step instructions
- Preheat your oven to 350°F (175°C).
- Grease a 9×13-inch baking dish to prevent sticking.
- In a large mixing bowl, combine the whole kernel corn, creamed corn, sour cream, and melted butter. Stir until thoroughly blended.
- Next, add the Jiffy corn muffin mix into the bowl and stir until just combined. Be careful not to overmix.
- Fold in the shredded cheddar cheese, diced green chilies, red and green bell peppers, chopped green onions, ground cumin, salt, and pepper. Ensure the mix is evenly distributed.
- Pour the mixture into the prepared baking dish, spreading it out evenly.
- Bake this delightful casserole in your preheated oven for 45-50 minutes, or until the top turns golden brown. A toothpick inserted in the center should come out clean.
- Let the casserole cool for a few minutes before serving. Garnish with freshly chopped cilantro for a burst of color and flavor.
