How to Store or Freeze Your Tacos
Allow the cooked tuna mixture to cool to room temperature before storing. This helps prevent condensation, which can make the taco shells soggy.
Transfer the cooled tuna mixture into an airtight container. For optimal freshness, use a container that fits the amount of tuna closely to minimize air exposure.
Store the tuna mixture in the refrigerator for up to 3 days. If you plan to keep it longer, consider freezing.
To freeze, place the tuna mixture in a freezer-safe container or a resealable plastic bag. Flatten the bag to remove excess air and ensure even freezing.
Label the container or bag with the date of storage to keep track of its freshness.
When ready to use, thaw the tuna mixture in the refrigerator overnight. Avoid thawing at room temperature to prevent bacterial growth.
Reheat the tuna mixture in a skillet over medium heat until warmed through. You may need to add a splash of olive oil to prevent sticking.
Store taco shells separately in their original packaging or in an airtight container to maintain their crispness.
Keep shredded lettuce and diced tomatoes in separate containers in the refrigerator. Use within 2-3 days for the best texture and flavor.
Shredded cheese can be stored in an airtight container or resealable bag in the refrigerator for up to a week. For longer storage, freeze the cheese and thaw it in the refrigerator before use.
Sour cream should be kept in its original container or transferred to an airtight container. Use within a week of opening for the best quality.
When assembling the tacos, warm the taco shells according to package instructions just before serving to ensure they remain crisp.
Assemble the tacos with the reheated tuna, fresh shredded lettuce, diced tomatoes, shredded cheese, and a dollop of sour cream for a delicious and convenient meal.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the assembled tuna tacos on a baking sheet. Cover them loosely with aluminum foil to prevent the taco shells from burning. Heat for about 10-15 minutes or until the tuna is warmed through.
For a quicker method, use a microwave. Place the tuna tacos on a microwave-safe plate. Cover them with a damp paper towel to keep the taco shells from becoming too hard. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you prefer a stovetop method, deconstruct the tuna tacos. Heat a skillet over medium heat and add a small amount of olive oil. Reheat the tuna mixture for about 3-4 minutes, stirring occasionally. Warm the taco shells separately in another skillet or in the oven. Reassemble the tacos with fresh lettuce, tomatoes, cheese, and sour cream.
For an air fryer method, preheat the air fryer to 350°F (175°C). Place the tuna tacos in the air fryer basket in a single layer. Heat for about 3-5 minutes, checking frequently to ensure the taco shells do not over-crisp.
