How to Make Grilled Cheese Casserole
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Grab a baking dish and generously spray it with nonstick cooking spray to prevent sticking.
Step 2: Prepare the Bread
Slice your chosen bread into cubes—aim for about one-inch pieces. There’s no need for precision here; just make sure they’re not too small or they’ll become mush!
Step 3: Mix the Cheeses
In a large bowl, combine shredded cheddar and mozzarella cheese. Feel free to mix it up with different cheeses if you’re feeling adventurous—gruyère anyone?
Step 4: Whisk Together Eggs and Milk
In another bowl, whisk together eggs and milk until well blended. Add salt and pepper to taste because we all know seasoning is key!
Step 5: Assemble the Casserole
Layer half of the bread cubes at the bottom of your prepared baking dish. Sprinkle half of the cheese mixture over the bread cubes. Repeat this process by adding the remaining bread cubes followed by the rest of the cheese.
Step 6: Pour Egg Mixture
Pour the egg mixture evenly over the layers in your baking dish, pressing down gently with a spatula to ensure everything gets soaked up nicely.
