Tips & Tricks
Perfecting the Casserole
To get the best flavor, make sure the bread is soaked well. This helps it absorb the egg mixture. I like to let it sit for a few minutes. This gives the bread a chance to soak up the goodness. For a golden cheese topping, add the cheese last and bake uncovered. This way, the cheese gets bubbly and brown.
Ingredient Substitutions
If you want a twist, try using different breads. Challah or whole grain bread can work nicely. You can also change up the veggies. Zucchini or mushrooms can add great taste. For meats, turkey sausage or bacon are tasty swaps.
Making Ahead Tips
You can prepare this casserole the night before. Just follow the steps up to pouring the egg mixture. Cover it well and store in the fridge. This way, you save time in the morning. For overnight storage, use plastic wrap or a lid. This keeps it fresh and ready to bake.
Variations
Vegetarian Version
You can easily make a vegetarian version of the Crack Breakfast Casserole. Simply swap out the cooked breakfast sausage. Use extra veggies instead. Consider adding mushrooms, zucchini, or sun-dried tomatoes. You can also add plant-based sausage if you want a similar taste. This keeps the dish hearty and full of flavor without meat.
Spicy Twist
For those who love heat, add jalapeños or hot sauce. Thinly slice fresh jalapeños and layer them with the veggies. If you prefer, mix hot sauce into the egg and milk mix. This will give the casserole a nice kick. Adjust the amount based on your heat tolerance for the best experience.
Breakfast Casserole with Different Cheeses
Change up the cheeses for a new taste. Instead of sharp cheddar, try mozzarella for a milder flavor. Gouda brings a creamy texture and richness. Feta adds a tangy bite that pairs well with the veggies. Feel free to mix and match your favorite cheeses to create a unique flavor profile.
Storage Info
Refrigeration
To store leftovers, let the casserole cool first. Then, cover it tightly with plastic wrap or foil. You can also use an airtight container. This keeps it fresh for up to three days in the fridge. If you want to enjoy it later, store it in smaller portions. This makes it easy to reheat just what you need.
Freezing Instructions
You can freeze the cooked casserole for longer storage. Once it cools, cut it into slices. Wrap each slice in plastic wrap, then place them in a freezer bag. Make sure to squeeze out as much air as you can. The casserole will keep well for up to three months in the freezer. To thaw, place it in the fridge overnight before reheating.
Reheating Methods
To reheat, I recommend using the oven for the best texture. Preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover it with foil. Heat for about 20 minutes. If you want a crispy top, remove the foil for the last five minutes. You can also use the microwave for quick reheating, but it may not be as crispy. Heat slices in 30-second intervals until warm.
