Serving & Storage Tips
Serving Suggestions
This Crab Casserole is just amazing on its own, but I love pairing it with a light salad or some garlic bread to scoop up every last bit of cheesy goodness! You can even serve it over rice or pasta for a more filling meal.
Storage
Leftovers? No problem! Your crab casserole will keep well in the fridge for about 3-4 days. Just make sure it’s in an airtight container.
Reheating Instructions
For the best results, reheat it in the oven at 350°F (175°C) to retain that crispy topping. Just cover it with foil for the first part to warm through, and then uncover it for a few minutes to crisp up the top again.
Freezer Friendly?
You can absolutely freeze this before baking it. Just assemble everything, then cover and freeze for up to 3 months. When you’re ready to bake, just pop it in the oven straight from the freezer, though you might need to add some extra baking time (maybe about 15-20 minutes).
Now that you have all the inside scoop on making this Crab Casserole, I can’t wait for you to try it! It’ll warm up your family dinners and put smiles on hungry faces.
