Ingredients:
- 8 slices of bread (your choice: white, whole wheat, or sourdough)
- 4 tablespoons of unsalted butter, softened
- 2 cups of shredded cheddar cheese
- 1 cup of shredded mozzarella cheese
- 4 large eggs
- 1 cup of whole milk
- 1 teaspoon of garlic powder
- 1 teaspoon of onion powder
- 1/2 teaspoon of salt
- 1/4 teaspoon of black pepper
- 1/4 teaspoon of paprika (optional, for a little kick)
- Fresh parsley or chives for garnish (optional)
Preparing the Bread
1. Start by preheating your oven to 350°F (175°C). This will ensure that your casserole cooks evenly and gets that lovely golden crust on top. 2. While the oven is heating, take your slices of bread and spread a thin layer of softened butter on one side of each slice. This will help create a crispy, golden exterior once baked. 3. Once all the bread is buttered, cut each slice into quarters. You can do this by cutting each slice in half and then cutting those halves into thirds. This will give you nice bite-sized pieces that will fit perfectly in the casserole dish.Layering the Casserole
4. Grab a large casserole dish (about 9×13 inches works great) and start layering the bread pieces. Begin by placing half of the bread pieces in the bottom of the dish, buttered side up. Make sure to spread them out evenly. 5. Next, sprinkle half of the shredded cheddar cheese over the bread layer. Follow this with half of the shredded mozzarella cheese. The combination of these two cheeses will give your casserole that gooey, melty texture we all love. 6. Now, repeat the layering process. Add the remaining bread pieces on top of the cheese, again buttered side up. Then, sprinkle the rest of the cheddar and mozzarella cheeses over the top. This double-layering will ensure that every bite is cheesy and delicious.Preparing the Egg Mixture
7. In a large mixing bowl, crack the 4 large eggs. Whisk them together until they are well combined and slightly frothy. This will help incorporate air into the mixture, making the casserole fluffy. 8. Pour in the 1 cup of whole milk and continue whisking until the mixture is smooth. The milk adds creaminess and richness to the casserole. 9. Now, add the garlic powder, onion powder, salt, black pepper, and paprika (if using) to the egg and milk mixture. Whisk everything together until all the spices are evenly distributed. This will infuse the casserole with flavor.Combining the Ingredients
10. Carefully pour the egg mixture over the layered bread and cheese in the casserole dish. Make sure to cover all the bread pieces so they soak up the egg mixture. You can use a spatula to gently press down on the bread to ensure it absorbs the liquid. 11. Once everything is well combined, let the casserole sit for about 10-15 minutes. This resting time allows the bread to soak up the egg mixture fully, ensuring a moist and flavorful casserole.Baking the Casserole
12. After the resting period, place the casserole dish in the preheated oven. Bake for 30-35 minutes, or until the top is golden brown and the cheese is bubbling. You can check for doneness by inserting a knife in the center; it should come out clean. 13. If you want an extra crispy top, you can broil the casserole for an additional 2-3 minutes at the end of the baking time. Just keep a close eye on it to prevent burning.Serving the Casserole
14. Once the casserole is done baking, remove it from the oven and let it cool for about 5-10 minutes. This will make it easier to cut and serve. 15. Using a sharp knife, cut the casserole into squares or rectangles, depending on your preference. Serve warm, garnished with fresh parsley or chives if desired. This adds a pop of color and a fresh flavor that complements the richness of the cheese. 16. Enjoy your delicious grilled cheese casserole with a side of tomato soup for a classic pairing, or serve it as a hearty breakfast or brunch dish. Its perfect for feeding a crowd or for meal prep throughout the week.Storage Tips
