Sous Vide Filet Mignon (Medium Rare) With Tzatziki Sauce, Made Easy

Step 1: Prepare the Steak
Start by seasoning the filet mignon steaks with 1 tsp salt and 1 tsp pepper. Don’t be shy with the seasoning; it enhances the flavor of the meat.
Step 2: Vacuum Seal
Place the seasoned steaks in a vacuum seal bag. Drizzle 2 tsp olive oil over the steaks and add 1 tbsp garlic, minced. Vacuum seal the bag tightly to ensure no water enters during the sous vide process.
Step 3: Sous Vide Cooking
Fill a large pot with water and attach your sous vide precision cooker. Set it to 130°F (54°C) for medium rare. Once the water has reached the desired temperature, submerge the vacuum-sealed steaks into the water bath. Cook for 1 hour.
Step 4: Make the Tzatziki Sauce
While the steaks are cooking, prepare the tzatziki sauce. In a mixing bowl, combine 32 oz Greek yogurt, plain, 1 medium cucumber, diced, 1 lemon, juiced, 1 tbsp dill, fresh, chopped, 1 tsp salt, and 1 tsp pepper. Mix well and refrigerate until ready to serve.
Step 5: Sear the Steak
Once the steak has finished cooking, remove it from the sous vide bag and pat it dry with paper towels. Heat a skillet over medium-high heat and add 1 tbsp butter and 1 tbsp olive oil. When the butter is melted and foamy, add the steak to the skillet. Sear for about 1-2 minutes on each side until a golden-brown crust forms.
Step 6: Plate and Serve
Slice the filet mignon and place it on a plate. Add a generous dollop of tzatziki sauce on the side, and sprinkle with 1 tsp parsley, fresh, chopped for garnish. Enjoy your Sous Vide Filet Mignon (Medium Rare) With Tzatziki Sauce!
