Difficulty Level
Medium – perfect for home chefs aiming to master sous vide and paleo flavor profiles
Ingredients
- 1.5 lbs flank steak, trimmed
- 2 tbsp avocado oil (or other paleo-friendly oil)
- 3 cloves garlic, minced
- 2 tsp smoked paprika
- 1 tsp ground cumin
- 1 tsp dried oregano
- 1/2 tsp sea salt
- 1/2 tsp freshly cracked black pepper
- 1 tbsp apple cider vinegar
- 2 tbsp fresh lime juice
- 1 tbsp fresh cilantro, finely chopped (for garnish)
- Optional Paleo Marinade Add-ins: 1 tsp chili flakes, 1 tbsp coconut aminos
Instructions
- Marinate the steak: In a small bowl, combine avocado oil, garlic, smoked paprika, cumin, oregano, salt, pepper, apple cider vinegar, and lime juice. Massage this marinade evenly into the flank steak.For enhanced flavor, cover and refrigerate for 2 hours.
- Seal and prepare for sous vide: Place the marinated steak in a vacuum-seal bag or heavy-duty ziplock, removing as much air as possible to ensure even cooking. Set sous vide precision cooker to 131°F (55°C) for a perfect medium-rare texture.
- Cook sous vide: Submerge the sealed bag in the water bath.Cook for 2 hours. This precision lock-in ensures the steak is tender, juicy, and cooked edge-to-edge without overcooking.
- Preheat the searing pan: Once sous vide cooking finishes, remove the steak and pat dry with paper towels-drying is crucial for an impeccable crust. Heat a cast iron skillet or heavy-bottom pan over high heat.
- Sear the steak: Add a small splash of avocado oil and sear the flank steak for 2-3 minutes per side, developing a rich caramelized crust while preserving the cooked interior.
- Rest and slice: Let the steak rest on a cutting board for 5 minutes, then slice thinly against the grain to maximize tenderness.
- garnish and serve: Sprinkle fresh cilantro over the sliced steak. Serve immediately while warm.
Tips for Success
- Marinate longer for deeper flavor: While 2 hours is ideal, flank steak can be marinated up to 8 hours for bolder results.
- Dry thoroughly before searing: Moisture ruins the sear-pat the steak entirely dry to achieve that coveted crust.
- Adjust sous vide time for doneness: increase to 2.5 hours for medium or decrease to 1.5 hours for rare, but maintaining temperature is key.
- Paleo seasoning variations: Swap smoked paprika for chipotle powder or add fresh rosemary for herbal accents.
- Make-ahead tip: Cook sous vide then chill in the bag overnight. Reheat gently in sous vide bath for 45 minutes before searing to save time.
