Sous Vide Sirloin With Saute Potatoes

For the Sirloin：
Step 1：
Set the Sous Vide Precision to 131°F /55°C.

Step 2：
Season the steak with salt, pepper and oil. Place in a large zipper lock and place the bag in the water bath. Set the timer for 2 hours.

Step 3：
When the timer goes off, remove the bag from the water bath. Remove the steak from the bag and pat dry.

Step 4：
Heat oil and butter in a pan over medium-high heat . Add the steak to the pan and sear on the both side until golden brown, about 1 minute.

Step 5：
Remove steak from the pan and let rest for five minutes before serving.

For the Saute Potatoes：
Step 1：
Clean medium-sized unpeeled potatoes. Chop the potatoes into uniformly sized chunks.

Step 2：
Add 60 ml oil and 50 g butter to the heated frying pan. Add the potatoes to the frying pan in 1 layer. Saute the potatoes at medium-high heat. The cooking time will be roughly 7 minutes. Turn or flip the potato pieces only after the bottoms begin to brown. Turn them all 2 or 3 times until they are golden brown on both sides.

Finishing Steps：
Transfer the cooked potatoes to a serving bowl using a slotted spoon. You may want to briefly drain the potatoes on paper towels to blot some of the butter before putting them in a bowl. Add ground black pepper and sea salt to taste. Sprinkle of freshly chopped parsley if desired.
