How to Make Sous Vide Flank Steak
Step 1: Preheat the Water Bath
Set your sous vide immersion circulator to 130°F and let the water reach the desired temperature. This ensures even cooking from edge to edge.
Step 2: Season the Steak
Pat the flank steak dry with paper towels, then rub it with olive oil. Season generously with kosher salt, black pepper, minced garlic, rosemary, and thyme. Press the seasonings gently into the meat.
Step 3: Seal the Steak
Place the seasoned steak in a vacuum-sealable bag or a zip-top bag. Use the water displacement method to remove air, then seal the bag tightly.
Step 4: Cook the Steak
Submerge the bag in the preheated water bath and cook for 2 hours. Make sure the steak is fully covered by the water for even cooking.
Step 5: Sear the Steak
After cooking, pat the steak dry and sear it in a smoking-hot cast-iron skillet for 1–2 minutes per side. This creates a beautiful crust while keeping the inside tender.
Step 6: Slice and Serve
Let the steak rest for 5 minutes, then slice it thinly against the grain. Serve immediately and enjoy!

Mistakes to Avoid
Even the most seasoned cooks can make mistakes when preparing Sous Vide Flank Steak. One common error is not properly sealing the bag, which can lead to water seeping in and ruining the texture. To prevent this, double-check the seal or use a vacuum sealer for extra security. Another mistake is overcooking during the searing process. Remember, the steak is already cooked to perfection—just a quick sear on each side is all you need for that beautiful crust.
Timing is also crucial. While sous vide cooking is forgiving, leaving the steak in the water bath for too long can make it mushy. Stick to the recommended time and temperature for the best results. For more detailed guidance, check out this Sous Vide Flank Steak Basics guide. And if you’re looking for more tips on avoiding common pitfalls, my Stuffed Chicken Breasts recipe includes helpful pointers for precision cooking.
Lastly, don’t forget to let the steak rest after searing. Cutting into it too soon can cause the juices to escape, leaving you with a drier result. Patience is key! I learned this the hard way during a family dinner, but now it’s a step I never skip.
How to Store Sous Vide Flank Steak
One of my favorite things about Sous Vide Flank Steak is how well it stores. I often prepare extra portions to enjoy throughout the week.

If you’d like to freeze it, wrap the steak tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag. It can last up to three months in the freezer. When you’re ready to enjoy it, thaw it in the fridge overnight and reheat it gently in a skillet or sous vide bath.
