Why sous vide a ribeye at 129°F?

Because 129°F is the exact internal temperature for medium rare. Sous vide cooks the steak to that temperature edge to edge and holds it there, so there is no overcooking possible and no carryover to predict. The water is the recipe — choose a different bath temperature to dial the doneness up or down.

How long can I leave a ribeye in the sous vide bath?

90 minutes to 2 hours is the sweet spot for a 1.5-inch ribeye. Up to 4 hours at 129°F is safe and fine; beyond about 4 hours the long heat starts to break down the texture and the steak turns soft.

Why pat the steak dry before searing?

A wet surface steams instead of searing, so it will not crust. The sous vide bag liquid is the enemy of the crust. Discard the bag juices and pat every side completely dry — a bone-dry surface is what makes the quick 60-second sear actually work.

Is sous vide ribeye cooked entirely indoors?

Yes. The bath and the cast iron sear both happen on the countertop and stovetop, so this is a fully indoor method — no grill required. It is one of the most reliable ways to cook a steakhouse ribeye in any kitchen.

Sous Vide Ribeye (Cast Iron Finish)

Description

Sous vide takes the guesswork out of a ribeye. The water bath holds the steak at exactly the doneness you want, edge to edge, then a screaming-hot cast iron builds the crust. Salt and pepper only — the beef is the star. A fully indoor, foolproof steakhouse dinner.

Ingredients

Scale

1 boneless ribeye, 1.5-2 inches thick (about 12-16 oz)
1 tablespoon kosher salt
1 teaspoon coarsely cracked black pepper
1 tablespoon unsalted butter (for the bag)
1 sprig thyme or rosemary, optional (for the bag)
1 tablespoon neutral oil, such as avocado or grapeseed (for the sear)
Florida Pure Sea Salt Pure Flaked, for finishing

Instructions

Pat the ribeye dry. Season both sides generously with kosher salt and cracked pepper.
Slip the steak into a sous vide bag with the butter and thyme. Seal by vacuum sealer or water displacement.
Heat the water bath to 129°F for medium rare.
Submerge the bag, clip it to the side, and cook 90 minutes to 2 hours.
Pull the bag from the bath. Lift out the steak and discard the bag liquid.
Pat the ribeye completely dry on all sides.
Heat a cast iron skillet over high heat until ripping hot, 5 to 7 minutes. Add the oil.
Sear the steak 45 to 60 seconds per side. Stand it on the fat edge for 20 to 30 seconds.
Move the steak to a cutting board and rest 2 to 3 minutes.
Slice against the grain, half an inch thick. Finish with flaky Florida Pure Sea Salt.

Notes

The bath temperature is the doneness: 129°F gives edge-to-edge medium rare. Choose a higher bath temp for more done.

Pat the steak bone-dry before searing — a wet surface steams instead of crusting.
