Elevate your steak night with this Sous Vide Flank Steak recipe, crafted for effortless perfection. You'll achieve restaurant-quality results at home, with rich flavors that make every bite enjoyable. Experience a steak dish that is simple yet incredibly rewarding, requiring almost no prep time.

The sous vide is a surefire way to dish up a perfectly cooked meal every time.
From simple weeknight sous vide chicken drumsticks, to sous vide tri tip and picanha, it is a simple tool I turn to on both busy nights and when I want to impress.
Cooking flank steak in the sous vide is one of my favorite ways to serve it up. It requires just minutes of hands on time, and comes out perfect every time.

Ingredients
- Flank Steak: With its big, beefy flavor, this cut of beef is perfect for the sous vide. The long cooking time tenderizes the meat, and the method insures it is perfectly cooked all the way through.
- Sea Salt: Kosher salt is also an option.
- Garlic Powder: Fresh garlic is also an option, but some people don't care for it in the sous vide because it can give a raw garlic flavor that can be offputting. You could use onion powder if you prefer.
- Dried Oregano: Italian seasoning is another option.
- Avocado Oil: Perfect for high-heat searing after sous vide cooking. Use your favorite high-heat oil.
- Soy Sauce: Tamari or coconut aminos will keep this recipe gluten-free.
Tips and Tricks
- Let the steak sit with the seasoning for at least an hour before cooking. This will result in enchanced flavor and texture, as the salt will have time to penetrate the muscle fibers of the steak.
- I prefer my flank steak cooked to medium rare. You can adjust the water temperture if you want yours to be rare (120°F), medium (140°F), or medium well (150°F).
- If you're planning ahead, cooked sous vide steak can be refrigerated for up to four days and seared right before serving, providing a quick meal prep solution. I recommend keeping it sealed in your vacuum sealer bag.
- Experiment with finishing flavors. Chimichurri is a go-to for flank steak, but compound butter or horseradish sauce also work beautifully.
