The Best Porterhouse Steak Recipes: How to Cook Tender, Flavorful Porterhouse Steak Every Time

Porterhouse steak is one of the most impressive cuts from the loin primal. It gives you two steakhouse favorites in one cut: a flavorful New York strip on one side of the bone and a tender filet-style tenderloin on the other. That makes porterhouse steak a great choice for special dinners, backyard grilling, date nights, and meals where you want the steak to be the centerpiece.

If you are wondering how to cook porterhouse steak so both sides turn out tender and juicy, the key is careful heat control. The strip side and tenderloin side cook a little differently, so porterhouse steak does best with methods that bring the steak up to temperature evenly before finishing with a hot sear.

At Homestead Natural Meats, our locally raised beef is aged on the rail for 11 to 14 days to help create the tenderness and flavor our customers love. Whether you reverse sear it, cook it in cast iron, or grill it over high heat, porterhouse steak is a premium cut that rewards simple seasoning, a good thermometer, and a proper rest before slicing.

What Is Porterhouse Steak?

Porterhouse steak is a large bone-in steak cut from the short loin. It has a T-shaped bone running through the center, with New York strip steak on one side and tenderloin on the other. Because it includes both cuts, porterhouse steak offers a combination of bold beef flavor and buttery tenderness.

The strip side is larger, beefier, and slightly firmer. The tenderloin side is smaller, leaner, and very tender. A good porterhouse steak is usually cut thick, which makes it ideal for reverse searing, cast iron cooking, and grilling.

Porterhouse steak is a great choice for:

• Steakhouse-style dinners at home
• Reverse-seared steak recipes
• Cast iron steak recipes
• Backyard grilling
• Date night meals
• Holiday dinners
• Special occasion meals
• Sharing between two people

For the best results, cook porterhouse steak to temperature rather than relying only on time. A meat thermometer helps protect the tenderloin side from overcooking.

Porterhouse Steak vs. T-Bone Steak

Porterhouse steak and T-bone steak are very similar because both include a T-shaped bone with strip steak on one side and tenderloin on the other. The main difference is size. Porterhouse steak comes from the rear portion of the short loin, where the tenderloin section is larger.

A T-bone steak has a smaller tenderloin portion, while a porterhouse has a larger tenderloin side. Both are excellent grilling steaks, but porterhouse is usually considered the larger, more premium version.

Best Ways to Cook Porterhouse Steak

The best way to cook porterhouse steak depends on thickness and the tools you have available. Because porterhouse has two different muscles on one bone, gentle heat followed by a hot sear is one of the most reliable methods.

The three best cooking methods for porterhouse steak are:

1. Reverse searing for even doneness and a strong crust.
2. Cooking in cast iron with rosemary garlic butter for a steakhouse-style finish.
3. Grilling with simple steakhouse seasoning for smoky flavor and bold presentation.

Below are three porterhouse steak recipes that cover the most popular ways to cook this premium loin cut.

1. Reverse-Seared Porterhouse Steak with Garlic Herb Butter

Reverse-seared porterhouse steak is one of the best ways to cook this thick, premium cut. The steak cooks gently at a low temperature first, then finishes with a hot sear for a browned crust. Garlic herb butter adds richness while letting the beef stay at the center of the plate.

Serves: 2

Total Time: 1 to 1 1/2 hours

Method: Reverse Sear

Ingredients

• 1 thick-cut Homestead porterhouse steak, about 1 1/2 to 2 inches thick
• 1 1/2 tsp kosher salt
• 1 tsp black pepper
• 1 tsp garlic powder
• 1 Tbsp avocado oil or other high-heat cooking oil
• 4 Tbsp unsalted butter, softened
• 2 cloves garlic, minced
• 1 tsp chopped fresh rosemary
• 1 tsp chopped fresh thyme

Instructions

1. Pat the porterhouse steak dry with paper towels.
2. Season all sides with kosher salt, black pepper, and garlic powder.
3. Let the steak rest at room temperature for 30 to 45 minutes before cooking.
4. Preheat oven to 250 degrees F. Place the steak on a wire rack set over a baking sheet.
5. Cook until the internal temperature reaches 110 to 115 degrees F for medium rare before searing.
6. While the steak cooks, mix softened butter with garlic, rosemary, and thyme. Set aside.
7. Heat a cast iron skillet or grill over high heat. Add avocado oil, then sear the steak for 1 to 2 minutes per side until a deep crust forms.
8. Top with garlic herb butter and let it melt over the hot steak.
9. Rest for 10 minutes before slicing the strip and tenderloin away from the bone.

Cooking Tip: Check the tenderloin side first when taking the temperature. It is leaner and can overcook faster than the strip side.

2. Cast Iron Porterhouse Steak with Rosemary Garlic Butter

Cast iron porterhouse steak is a great indoor method when you want a rich crust and steakhouse-style flavor. A hot skillet sears the beef, while rosemary garlic butter adds a savory finish.

Serves: 2

Total Time: 35 to 45 minutes

Method: Cast Iron

Ingredients

• 1 Homestead porterhouse steak, about 1 1/2 inches thick
• 1 1/2 tsp kosher salt
• 1 tsp coarse black pepper
• 1 Tbsp avocado oil or other high-heat cooking oil
• 3 Tbsp unsalted butter
• 3 cloves garlic, smashed
• 2 sprigs fresh rosemary
• 1 sprig fresh thyme, optional

Instructions

1. Pat the porterhouse steak dry and season both sides with salt and pepper.
2. Let the steak rest at room temperature for 30 minutes before cooking.
3. Preheat oven to 400 degrees F.
4. Heat a large cast iron skillet over high heat until very hot, then add avocado oil.
5. Sear the porterhouse for 2 to 3 minutes on the first side without moving it.
6. Flip the steak and sear the second side for 2 minutes.
7. Add butter, garlic, rosemary, and thyme to the skillet. Spoon the melted butter over the steak for 1 minute.
8. Transfer the skillet to the oven and cook until the steak reaches your desired internal temperature.
9. Rest for 10 minutes before slicing and serving with the rosemary garlic butter from the pan.

Cooking Tip: Make sure your skillet is large enough for the porterhouse to sit flat. Good contact with the pan helps create a better crust.

3. Grilled Porterhouse Steak with Steakhouse Seasoning

Grilled porterhouse steak is simple, bold, and perfect for a backyard meal. A classic steakhouse seasoning gives the beef a savory crust, while the grill adds smoky flavor and a beautiful presentation.

Serves: 2

Total Time: 35 to 50 minutes

Method: Grill

Ingredients

• 1 Homestead porterhouse steak, about 1 1/2 to 2 inches thick
• 1 Tbsp avocado oil or olive oil
• 1 1/2 tsp kosher salt
• 1 tsp coarse black pepper
• 1 tsp garlic powder
• 1/2 tsp onion powder
• 1/2 tsp smoked paprika
• 1 Tbsp chopped parsley, optional for serving

Instructions

1. Pat the porterhouse steak dry with paper towels and brush lightly with oil.
2. Mix salt, pepper, garlic powder, onion powder, and smoked paprika in a small bowl.
3. Season both sides of the steak with the steakhouse seasoning.
4. Let the steak rest at room temperature for 30 to 45 minutes before grilling.
5. Preheat the grill with two heat zones: one side for direct high heat and one side for indirect heat.
6. Place the steak over direct heat and sear for 2 to 3 minutes per side.
7. Move the steak to indirect heat, close the lid, and continue cooking until it reaches your desired internal temperature.
8. Rest for 10 minutes before slicing the steak away from the bone and serving.

Cooking Tip: Position the tenderloin side slightly farther from the hottest part of the grill to help it stay tender and juicy.

Porterhouse Steak Temperature Guide

Porterhouse steak is best cooked with an instant-read thermometer. Because the tenderloin side is leaner than the strip side, check both sides and pull the steak a few degrees before your final target temperature.

• Rare: 120 to 125 degrees F
• Medium rare: 130 to 135 degrees F
• Medium: 140 to 145 degrees F
• Medium well: 150 to 155 degrees F
• Well done: 160 degrees F and above

For most porterhouse steak recipes, medium rare is a great target because it keeps both the strip side and tenderloin side juicy and tender.

How to Keep Porterhouse Steak Tender and Juicy

Porterhouse steak is naturally tender, but it can dry out if it is cooked too quickly or taken too far past medium. The best approach is to season simply, cook carefully, and let the steak rest before slicing.

For a tender, juicy porterhouse steak, remember these tips:

• Pat the steak dry before seasoning.
• Season generously with salt and pepper.
• Let the steak rest at room temperature before cooking.
• Use a thermometer to check both the strip and tenderloin sides.
• Use reverse searing or two-zone grilling for thicker steaks.
• Rest the steak for 10 minutes before slicing.
• Slice the meat away from the bone, then cut against the grain.

What to Serve with Porterhouse Steak

Porterhouse steak pairs well with classic steakhouse sides, simple vegetables, and hearty family-style dishes. Since the steak already brings two premium cuts to the plate, the sides can stay simple.

Good side dishes for porterhouse steak include:

• Garlic mashed potatoes
• Baked potatoes
• Roasted asparagus
• Grilled corn
• Caesar salad
• Roasted mushrooms
• Creamed spinach
