How to Store or Freeze Your Flank Steak
To store your marinated flank steak, place it in an airtight container or resealable plastic bag. Ensure that the container is well-sealed to prevent any air from entering, which can cause the meat to dry out.
If you plan to enjoy the flank steak within a few days, keep it in the refrigerator. It will stay fresh for up to 3-4 days. Make sure to place it on the bottom shelf of the fridge to avoid any cross-contamination with other foods.
For longer storage, freezing is an excellent option. Place the marinated flank steak in a freezer-safe bag or container. Remove as much air as possible before sealing to prevent freezer burn. Label the bag with the date to keep track of its freshness.
When you're ready to cook the frozen flank steak, transfer it to the refrigerator to thaw. This slow thawing process helps maintain the meat's texture and flavor. Allow at least 24 hours for the steak to thaw completely.
If you're in a hurry, you can use the cold water thawing method. Place the sealed bag of flank steak in a bowl of cold water, changing the water every 30 minutes. This method typically takes about 1-2 hours, depending on the thickness of the steak.
Once thawed, cook the flank steak as per the recipe instructions. Do not refreeze the steak once it has been thawed, as this can affect the quality and safety of the meat.
For added convenience, you can also freeze the marinade separately. Pour the marinade into an ice cube tray and freeze. Once frozen, transfer the marinade cubes to a freezer bag. This way, you can easily add the marinade to the steak when you're ready to cook.
If you have leftover cooked flank steak, store it in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days. Reheat gently in a skillet or microwave, adding a splash of olive oil or beef broth to keep it moist.
For freezing cooked flank steak, wrap it tightly in aluminum foil or plastic wrap, then place it in a freezer-safe bag. Label with the date and freeze for up to 2-3 months. Thaw in the refrigerator before reheating.
How to Reheat Leftovers
Oven Method: Preheat your oven to 250°F. Place the flank steak on a baking sheet and cover it with aluminum foil to retain moisture. Heat for about 20-25 minutes or until warmed through. This method ensures the steak remains juicy and tender.
Stovetop Method: Slice the flank steak thinly against the grain. Heat a skillet over medium heat and add a splash of olive oil. Once the oil is hot, add the steak slices and cook for 2-3 minutes, flipping occasionally until heated through. This method is quick and helps maintain the steak's flavor.
Microwave Method: Place the flank steak slices on a microwave-safe plate. Cover with a damp paper towel to prevent drying out. Microwave on medium power for 1-2 minutes, checking and flipping halfway through. This method is convenient but may slightly alter the texture.
Sous Vide Method: If you have a sous vide machine, set it to 130°F. Place the flank steak in a vacuum-sealed bag and immerse it in the water bath for about 45 minutes. This method is excellent for preserving the steak's original texture and flavor.
Grill Method: Preheat your grill to medium heat. Wrap the flank steak in aluminum foil and place it on the grill for about 5-7 minutes, flipping halfway through. This method adds a nice char and reheats the steak evenly.
Air Fryer Method: Preheat your air fryer to 350°F. Place the flank steak slices in the air fryer basket in a single layer. Heat for 3-5 minutes, shaking the basket halfway through. This method is quick and gives a slightly crispy edge to the steak.
