Helpful Technique for Perfecting This Breakfast Casserole

When preparing the croissant pieces for this breakfast casserole, it's important to let them stale a bit before using. This can be done by leaving them out overnight. Stale croissants will absorb the egg mixture better, leading to a more flavorful and cohesive casserole. If you don't have time to let them stale naturally, you can also lightly toast them in the oven for a few minutes before adding them to the mixture. This will help to remove some of the moisture and achieve a similar result.

Time-Saving Tips for Making Sausage and Egg Croissant Breakfast Casserole

Prep ahead: Prepare the sausage and onion mixture the night before and store it in the refrigerator. In the morning, all you have to do is assemble the casserole and bake it.

Bake in advance: You can bake the casserole the night before, refrigerate it, and then reheat portions in the morning for a quick and easy breakfast.

Quick assembly: Cut the croissants into pieces the night before and store them in an airtight container. This way, you can quickly assemble the casserole in the morning.

Multi-task: While the casserole is baking, use that time to prepare a side dish or set the table for a complete breakfast experience.

Storage and Freezing Instructions for Sausage and Egg Croissant Breakfast Casserole

Allow the breakfast casserole to cool completely before storing or freezing. This will prevent condensation from forming and making the casserole soggy.
To store in the refrigerator, cover the casserole dish tightly with plastic wrap or aluminum foil. It will keep well for up to 4 days in the fridge.
For longer storage, freeze the casserole:
- Cut the cooled casserole into individual portions.
- Wrap each portion tightly in plastic wrap, then place the wrapped portions in a freezer-safe container or freezer bag.
- Label the container or bag with the date and contents.
- Freeze for up to 2 months for best quality.
To reheat the frozen casserole:
- Remove the desired number of portions from the freezer and let them thaw in the refrigerator overnight.
- Unwrap the thawed portions and place them in a microwave-safe dish.
- Microwave on high for 1-2 minutes, or until heated through. Alternatively, you can reheat the portions in a preheated 350°F (175°C) oven for about 10-15 minutes.
If you want to freeze the entire casserole unbaked, assemble it in a freezer-safe dish, cover tightly with plastic wrap and aluminum foil, and freeze for up to 1 month. When ready to bake, thaw the casserole overnight in the refrigerator, then bake as directed in the recipe, adding an extra 10-15 minutes to the baking time to account for the colder starting temperature.

How To Reheat Leftovers

To reheat leftover sausage and egg croissant breakfast casserole, preheat your oven to 350°F (175°C). Cover the casserole dish with aluminum foil and place it in the oven for 15-20 minutes, or until it's heated through. This method helps to retain the moisture and prevent the croissants from drying out.
Another option is to reheat individual portions in the microwave. Place a slice of the casserole on a microwave-safe plate and heat it on high power for 1-2 minutes, or until it's warmed to your liking. Be careful not to overheat, as this can cause the eggs to become rubbery and the croissants to turn soggy.
For a crispy top, you can also reheat the casserole in a skillet on the stovetop. Melt a small amount of butter in the skillet over medium heat, then add a slice of the casserole. Cover the skillet with a lid and heat for 3-4 minutes, or until the bottom is crispy and the casserole is heated through.
If you want to freshen up the flavors of the leftover casserole, consider adding some chopped fresh herbs like parsley or green onions before reheating. You can also sprinkle some extra shredded cheese on top for added richness and texture.
Lastly, if you have an air fryer, you can use it to reheat the casserole while maintaining a crispy texture. Preheat the air fryer to 350°F (175°C), place a slice of the casserole in the basket, and cook for 3-5 minutes, or until it's heated through and the top is crispy.
