Best ways to enjoy it
This casserole is incredibly versatile in how you serve it. For a classic experience, dish it out warm with a sprinkle of fresh parsley for color. Pair it with a fresh side salad for a complete meal, or serve it alongside some fluffy scrambled eggs for a brunch spread that will impress your guests. Feel free to add hot sauce or even a dollop of sriracha for those who enjoy an extra kick!
Storage and reheating tips
If you happen to have leftovers (though they’re rare!), store your casserole in an airtight container in the refrigerator for up to 3 days. To reheat, simply place it in the microwave or oven until heated through. For longer storage, you can freeze the casserole in portions. Wrap it well in plastic wrap and aluminum foil to prevent freezer burn; it will keep for about 2 months. When you’re ready to enjoy it again, bake from frozen, adding time as needed.
Helpful cooking tips
- Make the sausage hash brown mixture the night before for an even quicker dinner. Just cover it and leave it in the fridge until you’re ready to pop it in the oven.
- If you want to make it even creamier, consider adding a bit of cream cheese to the mix.
- Always taste the mixture before baking to ensure it is seasoned just right; remember that the cheese adds saltiness as well.
Creative twists
Feel free to experiment with this recipe to match your family’s taste preferences. Try adding some chopped bell peppers for extra veggies, or mix in some spicy sausage for a little heat. You could even switch up the cheese, using pepper jack or mozzarella for different flavors.
