This classic porterhouse steak with herbed butter is the ultimate choice for a special dinner. Combining both the tender fillet and the flavourful sirloin, this impressive cut of beef is enhanced by a simple yet luxurious compound butter infused with fresh chives, thyme and marjoram. Searing the meat in a hot frying pan before finishing it in the oven ensures a beautifully caramelised crust while keeping the centre succulent and perfectly pink.
As a diabetes-friendly option, this dish focuses on high-quality protein and healthy fats without the need for sugary marinades or heavy sauces. Serving the steak sliced across the grain makes it easy to share, and the addition of the savoury herb butter provides a rich finish that complements the natural grass-fed flavours of the beef. Pair it with a crisp green salad or roasted seasonal vegetables for a complete, nutritious meal.

Ingredients for Porterhouse Steak with Herbed Butter
1/4 cup mixed fresh herbs, such as chives, thyme leaves, and marjoram leaves, finely chopped
110g (1 stick) unsalted butter, at room temperature
Kosher salt
Freshly ground black pepper
2 porterhouse steaks, (2-inch thick), about 1.8kg 2 tablespoons vegetable oil
2 tablespoons butter
Kosher salt
Freshly ground black pepper
How to make Porterhouse Steak with Herbed Butter
In a bowl, using a wooden spoon, stir together the herbs and butter. Season to taste with salt and pepper. Spoon mixture generously into ramekins and use the back of a butter knife to smooth the surface, removing any extra. Cover with plastic wrap and place in the refrigerator.
Preheat oven to 177°C. Let steak sit at room temperature for 30 minutes.
Pat steaks dry and season generously with salt and pepper. Heat a large skillet over medium-high heat, and add 1 tablespoon oil to pan. When oil begins to smoke, add the first steak and cook until brown and crusted, 3 to 4 minutes per side. Melt 1 tablespoon of butter in pan and spoon over steak to baste. Remove steak from heat and set aside. Wipe out the skillet and repeat with the second steak.
Place both steaks on a rimmed baking sheet fitted with a wire rack and place in oven to cook until an instant-read thermometer inserted into the centre of the steak registers 49°C for medium-rare, about 5 minutes (or 52°C for medium, about 10 minutes). Transfer steaks to a wooden board to rest, about 10 minutes.
To serve: Cut meat off both sides of the bone, leaving you with two pieces of steak. Slice each steak across the grain, then rearrange the slices around the bone on a platter. Serve with herbed butter.
