How to Store / Freeze This Dish
- Allow the tuna casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
- Transfer the cooled casserole into an airtight container. If you prefer, you can also use a resealable plastic bag, but make sure to remove as much air as possible to maintain freshness.
- Label the container or bag with the date and contents. This ensures you know exactly what it is and when it was made.
- Store the container in the refrigerator if you plan to consume the casserole within 3-4 days. For longer storage, place it in the freezer.
- To freeze, wrap the container in a layer of aluminum foil for extra protection against freezer burn. This is especially useful if you’re using a baking dish that doesn’t have a tight-fitting lid.
- When ready to reheat, if frozen, transfer the casserole to the refrigerator to thaw overnight. This gradual thawing process helps maintain the texture and flavor.
- Preheat your oven to 350°F (175°C) for reheating. Place the thawed casserole in an oven-safe dish if it’s not already in one.
- Cover the dish with aluminum foil to prevent the breadcrumbs from burning. Heat for about 20-25 minutes, or until the casserole is heated through.
- For a crispy topping, remove the foil during the last 5 minutes of reheating. This will give the breadcrumbs a nice, golden finish.
- If reheating a single portion, you can use a microwave. Place the portion in a microwave-safe dish, cover with a microwave-safe lid or plastic wrap, and heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.
