Description
A lighter corn casserole made with fat-free Greek yogurt, corn muffin mix, and egg whites for a creamy, lower-fat side dish.
Ingredients
- 8.5 oz (approximately 241 g) corn muffin mix
- 15 oz (425 g) can sweet yellow corn, drained
- 14.75 oz (418 g) can sweet corn cream style
- 16 oz (454 g) fat-free Greek yogurt
- 1/4 cup (56 g) melted light butter
- 1/2 cup (approximately 120 g) egg whites
- Cooking spray, as needed for greasing
Instructions
- Step 1: Preheat Oven: Preheat your oven to 350F. Spray a 9 x 13-inch baking dish with cooking spray to prevent sticking. Preheating ensures even cooking for your casserole.

- Step 2: Mix Ingredients: In a large bowl, combine all ingredients: corn muffin mix, drained sweet yellow corn, cream-style corn, fat-free Greek yogurt, melted light butter, and egg whites. Stir together with a spoon or spatula. The mixture will be fluffy; this is expected and indicates proper mixing.

- Step 3: Pour and Bake: Pour the mixture evenly into the prepared baking dish. Bake in the preheated oven for 55-60 minutes. Watch for the edges turning golden brown and the center becoming slightly firm. Insert a toothpick into the center to check doneness; it should come out clean.

- Step 4: Cool and Serve: Remove the casserole from the oven and let it cool for a few minutes before cutting. Cooling helps the casserole set and hold its shape when serving.
