How to Store / Freeze This Dish
- To store your Italian Style Tuna Salad, transfer it to an airtight container. This will help maintain the freshness and prevent any unwanted odors from seeping in.
- Place the container in the refrigerator. Your salad will stay fresh for up to 3 days. The cherry tomatoes and red onion may release some liquid over time, so give it a quick toss before serving.
- If you plan to make the salad ahead of time, consider adding the olive oil and lemon juice just before serving. This will keep the ingredients from becoming soggy.
- For freezing, note that tuna salad can be frozen, but the texture of the vegetables might change. If you still wish to freeze it, place the salad in a freezer-safe container or a heavy-duty freezer bag.
- Label the container with the date to keep track of its freshness. The salad can be frozen for up to 1 month.
- When ready to eat, thaw the salad in the refrigerator overnight. Once thawed, give it a good stir and adjust the seasoning if necessary. You might want to add a bit more olive oil and lemon juice to refresh the flavors.
- Avoid freezing if the salad contains any ingredients that don't freeze well, such as fresh herbs or certain types of vegetables. These can be added fresh after thawing.
How to Reheat Leftovers
If you prefer a warm salad, gently heat the tuna salad in a non-stick skillet over low heat. Stir occasionally to ensure even warming, but be careful not to overcook, as the tuna can become dry.
For a quick and easy method, microwave the tuna salad on a microwave-safe plate. Cover it with a microwave-safe lid or wrap to retain moisture. Heat on medium power for about 30 seconds to 1 minute, stirring halfway through.
If you want to add a bit of texture, spread the tuna salad on a baking sheet and warm it in the oven at 350°F (175°C) for about 5-7 minutes. This method can slightly roast the cherry tomatoes and red onion, adding a new dimension to the flavors.
For a more gourmet touch, place the tuna salad in a heatproof dish and warm it in a steamer for about 3-5 minutes. This method helps maintain the moisture and freshness of the ingredients.
If you have a toaster oven, use it to reheat the tuna salad at 325°F (160°C) for about 5 minutes. This method is convenient and helps to avoid overcooking.
For a cold option, simply let the tuna salad sit at room temperature for about 15-20 minutes before serving. This allows the flavors to meld together without the need for reheating.
