Pan-Seared T-Bone Steak with Rosemary Garlic Butter Tips, FAQ & printable recipe

Tips for success

To take your steak to the next level, make sure your cast-iron skillet is properly seasoned before you begin. A well-seasoned pan naturally prevents sticking and enhances the overall sear. Additionally, do not be afraid of high heat.

You want the pan to be smoking hot before the steak goes in. Open a window or turn on your kitchen exhaust fan to handle the smoke, as this high-temperature cooking is essential for creating that signature steakhouse crust that locks in all the rich flavors.

Always use a large, sturdy metal spoon for the butter basting process. A spoon with a slight curve helps scoop up the foaming butter, garlic, and rosemary easily from the tilted pan.

Be careful when tilting the cast-iron skillet, as it is heavy and the hot butter can splash. Keep a kitchen towel or silicone mitt on the skillet handle at all times to protect your hands from the intense heat of the pan during the basting process.

Variations

• Thyme and Shallot Baste: Swap the rosemary for fresh thyme sprigs and add thinly sliced shallots to the butter for a sweeter, more delicate herbal aroma.
• Spicy Garlic Butter: Add a pinch of crushed red pepper flakes to the foaming butter along with the garlic for a subtle, warming kick.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days.

Freezer

Freeze cooked steak in a freezer-safe bag for up to 2 to 3 months; thaw overnight in the fridge.

Reheat

Reheat gently in a 250°F (120°C) oven until warm, then flash-sear in a hot skillet for 30 seconds.

Store any leftover T-bone steak in an airtight container in the refrigerator within two hours of cooking. Kept properly, the cooked steak will remain fresh and delicious for up to three to four days. To preserve the moisture, keep the leftover garlic cloves and rosemary sprigs in the container with the steak, as they will continue to infuse the meat with subtle flavor during storage.

While steak is always best enjoyed fresh from the skillet, you can prep your ingredients ahead of time to make the cooking process seamless. Smash the garlic cloves and measure out the butter and fresh rosemary sprigs up to a day in advance, storing them in the refrigerator. You can also leave the steak uncovered on a wire rack in the fridge overnight to dry out the surface for an even better crust.

Serving ideas

Serve this magnificent pan-seared T-bone steak directly from the cutting board or transfer it to a warm platter. Slice the meat away from the bone on both sides, then cut it into thick, diagonal slices.

Arrange the slices back around the bone for an impressive, rustic presentation. Pour any remaining pan juices from the skillet or the resting plate directly over the sliced steak to add an extra layer of rich, buttery flavor.

This rich and savory steak pairs wonderfully with classic steakhouse sides. Consider serving it alongside creamy mashed potatoes, roasted asparagus, or a crisp wedge salad with blue cheese dressing.

The acidity of a simple green salad or roasted tomatoes helps cut through the richness of the butter-basted beef. Pair the meal with a robust red wine, such as a Cabernet Sauvignon or Syrah, to complement the deep, caramelized flavors of the crust.

Pan-Seared T-Bone Steak with Rosemary Garlic Butter

Prep 5 minCook 6 minRest 5 minTotal 16 minServes 2

Ingredients

• 1 T-bone steak (about 1.5 lbs, 1.5 inches thick)
• 4 tbsp unsalted butter
• 4 garlic cloves, smashed
• 3 fresh rosemary sprigs

Instructions

1. Pat the T-bone steak completely dry with paper towels. Let the steak sit at room temperature for no more than 30 minutes before cooking to ensure even heat distribution.
2. Heat a heavy cast-iron skillet over high heat until it is smoking hot. Carefully place the steak into the hot pan. Sear undisturbed for 2 to 3 minutes until a deep, golden-brown crust forms on the bottom.
3. Flip the steak using tongs. Immediately add the unsalted butter, smashed garlic cloves, and fresh rosemary sprigs to the skillet. Tilt the pan slightly and use a large metal spoon to continuously scoop the hot, foaming melted butter over the top of the steak for another 2 to 3 minutes.
4. Remove the skillet from the heat. Transfer the steak to a warm plate or cutting board to rest for at least 3 minutes, allowing the juices to redistribute. Ensure the thickest part of the meat reaches an internal temperature of 145°F (63°C) for a safe, perfectly cooked steak before slicing.
