Step-by-Step Instructions

Prepare the Onions
Heat the butter in a large skillet over medium heat. Add the thinly sliced sweet onions, seasoning them with salt and black pepper. Cook the onions slowly, stirring frequently, until they become soft, translucent, and slightly golden. This should take about 10–12 minutes.

Make the Onion Mixture
Once the onions are cooked, transfer them to a medium bowl. Stir in the sour cream, dried dill weed, and half of the shredded cheddar cheese. Mix until well combined, and set aside.
Prepare the Corn Layer
In a large mixing bowl, combine the cream-style corn, thawed frozen corn, milk, beaten egg, corn muffin mix, and Tabasco sauce (if using). Stir the mixture thoroughly until smooth and well incorporated.
Layer the Casserole
Lightly grease your 8×13-inch baking dish with butter or cooking spray. Pour the corn mixture into the dish, spreading it evenly to cover the bottom. Gently spoon the onion mixture over the top, ensuring an even layer. Sprinkle the remaining cheddar cheese over the onion layer to finish.
Bake to Perfection
Place the casserole in the preheated oven and bake for 45 minutes, or until the cheese on top is golden brown and the casserole has set firmly in the center. To test for doneness, gently press the center with a spoon—it should feel firm and no longer jiggle.
Serve and Enjoy
Remove the casserole from the oven and let it cool for about 5–10 minutes before serving. This brief resting period helps the flavors meld together beautifully. Serve warm as a side dish or a comforting main course.

Tips for Success

Caramelizing the Onions: Take your time with this step! Slowly cooking the onions brings out their natural sweetness, which is key to the dish’s rich flavor.
Adjusting the Spice: If you prefer a spicier dish, increase the Tabasco sauce to 1 teaspoon or add a pinch of cayenne pepper.
Cheese Variations: Feel free to experiment with different types of cheese. Monterey Jack or pepper jack would add a delightful twist.
Make It Ahead: You can assemble the casserole a day in advance. Just cover it tightly and refrigerate, then bake it fresh before serving.
