A beef porterhouse steak is one of the most impressive cuts you can cook at home. It’s large, rich in flavour, and combines two premium textures in one steak: the tenderloin and the strip loin, separated by a T-shaped bone. When cooked well, it delivers a steakhouse-style experience straight from your kitchen.
If you’ve been searching for how to cook porterhouse steak, or want to understand porterhouse steak calories and simple porterhouse steak recipes, this guide covers everything step by step in a practical, easy-to-follow way.
What Is a Beef Porterhouse Steak?
A porterhouse steak comes from the short loin section of beef. It is similar to a T-bone but with a larger portion of tenderloin.
Key features:
- Two cuts in one: strip steak + tenderloin
- Thick central bone for added flavour
- Large portion size (ideal for sharing)
- Best cooked using high heat methods
The porterhouse is often considered a “premium steakhouse cut” because of its size and tenderness combination.
When sourced well, such as from Gingin Grass Fed, it delivers strong natural beef flavour with minimal seasoning.
Porterhouse vs T-Bone: Quick Difference
People often confuse the two:
- T-bone steak: smaller tenderloin section
- Porterhouse steak: larger tenderloin section
So if you want more filet-style tenderness, porterhouse is the better choice.

How to Cook Porterhouse Steak (Step-by-Step Guide)
This section explains how to cook porterhouse steak for juicy, tender results every time.
Step 1: Bring Steak to Room Temperature
Take the steak out of the fridge 30–45 minutes before cooking.
Why it matters:
- Even cooking throughout
- Better crust formation
- Reduces risk of overcooked edges
Step 2: Season Simply
A beef porterhouse steak doesn’t need complicated seasoning.
Use:
- Sea salt
- Cracked black pepper
- Optional: light oil coating
Let it rest for 10–15 minutes after seasoning.
Step 3: Choose Your Cooking Method
You have two main options:
1. Pan + Oven Method (Most consistent)
- Sear in a hot cast iron pan
- Flip after 2–3 minutes
- Transfer to oven at 180–200°C
- Finish to desired doneness
2. Grill Method (Smoky flavour)
- Preheat grill to high heat
- Cook 3–5 minutes per side
- Move to indirect heat if needed
Step 4: Internal Temperature Guide
- Rare: 50–52°C
- Medium-rare: 54–57°C
- Medium: 60–63°C
- Medium-well: 65–68°C
Medium-rare is most commonly recommended for porterhouse steak.
Step 5: Rest Before Serving
Rest for 5–10 minutes after cooking.
This helps:
- Redistribute juices
- Improve tenderness
- Prevent dryness when slicing
Butter Basting for Extra Flavour
Butter basting adds a rich finish.
What you need:
- Butter
- Garlic cloves
- Rosemary or thyme
Method:
- Add butter after searing

This enhances crust and flavour depth.
