FIRST STEP: PREPARE THE BEEF TENDERLOIN

1. Trim the Beef Tenderloin: Start by trimming any excess fat or silver skin from the tenderloin steaks. The beef tenderloin should be relatively lean, and trimming ensures that the final product has a clean, smooth texture.

2. Season the Beef: Generously season both sides of each steak with salt and freshly ground black pepper. For extra flavor, you can also add a pinch of garlic powder, onion powder, smoked paprika, and a little Dijon mustard if you prefer a more seasoned crust.

3. Vacuum Seal the Steaks: Place each seasoned steak into a vacuum-seal bag, ensuring they are in a single layer. Add a sprig of rosemary or thyme and a couple of smashed garlic cloves to each bag for added flavor infusion. Vacuum-seal the bags, ensuring they’re tightly sealed.

SECOND STEP: SET UP THE SOUS VIDE WATER BATH

1. Prepare the Sous Vide Bath: Fill a large pot or sous vide container with water and attach your immersion circulator. Preheat the water to 130°F (54°C) for medium-rare or adjust to your preferred doneness. For medium, set the temperature to 140°F (60°C), and for well-done, set it to 150°F (65°C).

2. Cook the Beef: Submerge the vacuum-sealed bags with the steaks into the preheated water bath. Cook the beef tenderloin for 2 hours. The sous vide method allows the meat to cook evenly, so even if the steaks are thick, they’ll be perfectly cooked from edge to edge.

THIRD STEP: SEAR THE BEEF

1. Remove the Steaks from the Bag: After the 2-hour cooking period, remove the steaks from the vacuum-seal bags. Pat them dry with paper towels. This step is essential to get a good sear; any moisture on the surface can prevent the steak from developing a beautiful crust.

2. Sear the Steaks: Heat 2 tablespoons of olive oil in a heavy skillet over medium-high heat. Once the oil is hot, add the steaks to the skillet. Sear each side of the steaks for about 1-2 minutes until a golden, crispy crust forms. During the last 30 seconds of searing, add 2 tablespoons of unsalted butter, smashed garlic cloves, and the sprigs of rosemary or thyme to the skillet. Spoon the melted butter over the steaks to enhance the flavor.

3. Rest the Steaks: After searing, remove the steaks from the pan and let them rest for about 5 minutes. This allows the juices to redistribute, ensuring the meat stays tender and juicy.

FINAL STEP: SERVE AND ENJOY

1. Slice and Plate: After the resting period, slice the beef tenderloin against the grain and plate it. You can garnish with a sprinkle of fresh parsley and a dollop of extra butter for added richness.

2. Serve: Serve the sous vide beef tenderloin with your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad. The tenderloin pairs beautifully with a variety of sauces, such as chimichurri or a simple red wine reduction (if following a halal diet, omit any wine and opt for a flavorful broth or juice-based reduction).
