How to Store or Freeze Your Tacos
- Allow the tuna to cool completely before storing. This helps prevent condensation, which can make the taco shells soggy.
- Store the tuna mixture separately from the taco shells and fresh ingredients like shredded lettuce and diced tomatoes. This keeps everything fresh and prevents the shells from becoming soft.
- Place the cooled tuna mixture in an airtight container. It can be kept in the refrigerator for up to 3 days.
- For longer storage, freeze the tuna mixture. Transfer it to a freezer-safe container or a resealable plastic bag, removing as much air as possible to prevent freezer burn. Label the container with the date and freeze for up to 2 months.
- When ready to use, thaw the tuna mixture in the refrigerator overnight. Reheat it in a skillet over medium heat until warmed through.
- Store taco shells in their original packaging or in an airtight container at room temperature. They should stay fresh for about a week.
- Keep shredded lettuce and diced tomatoes in separate airtight containers in the refrigerator. Use them within 2-3 days for the best freshness.
- If you have leftover assembled tuna tacos, wrap them individually in plastic wrap or aluminum foil and store them in an airtight container in the refrigerator. Consume within 1-2 days for optimal taste and texture.
How to Reheat Leftovers
Preheat the oven to 350°F (175°C). Wrap the taco shells in aluminum foil and place them in the oven for about 10 minutes until they are warm and crispy. Meanwhile, reheat the tuna in a skillet over medium heat for 3-4 minutes, stirring occasionally.
Use a microwave-safe plate to reheat the tuna filling. Cover it with a damp paper towel to retain moisture and microwave on medium power for 1-2 minutes, stirring halfway through. Warm the taco shells separately in the microwave for about 20-30 seconds.
For a quick stovetop method, place the tuna filling in a non-stick skillet over medium heat. Stir occasionally until heated through, about 3-4 minutes. Warm the taco shells in a dry skillet over medium heat for about 30 seconds on each side.
If you have an air fryer, preheat it to 350°F (175°C). Place the taco shells in the basket and heat for 2-3 minutes until crispy. Reheat the tuna filling in a microwave or skillet as mentioned above.
For a toaster oven, preheat to 350°F (175°C). Wrap the taco shells in aluminum foil and place them in the toaster oven for about 5-7 minutes. Reheat the tuna filling in a skillet or microwave as previously described.
