Variations and Substitutions for Weber Kettle Grilled Porterhouse Steak with Thyme-Butter and Lemon

Try other cuts of steak – While the porterhouse steak is the star of this recipe, you can easily substitute it with other large cuts like rib eye, tomahawk chop, thick New York strip, London broil, or tri-tip. These cuts pair beautifully with the thyme-butter and lemon.
Use other fresh herbs – The combination of fresh thyme, butter, and grilled lemon enhances the beefy flavor of the steak, but feel free to experiment with other herbs. Dill, rosemary, sage, basil, oregano, or parsley can be excellent alternatives, offering different aromatic notes.
Add soaked wood chips – For a hint of smokey flavor, consider adding small wood chunks or wood chips soaked in water to the top of your charcoal pile. This will infuse the steak with a subtle smokiness that complements the thyme-butter and lemon.

Tips and Tricks for Weber Kettle Grilled Porterhouse Steak with Thyme-Butter and Lemon

What’s the best way to tell when your porterhouse steak is done – The most reliable method is to check the internal temperature with a meat thermometer, which should slide into the meat easily. Use a meat temperature chart to determine your preferred level of doneness. Alternatively, you can develop a good sense of doneness using the American Heart Association’s “steak doneness test” by pressing on the steak and feeling the resistance.
Should I remove the bone and carve the meat, or leave the meat on the bone – While many high-end steakhouses carve the New York strip and filet off the bone and serve it in smaller portions, leaving the bone attached to the steak at home creates a striking presentation. It signals generosity and allows your guests to carve the meat themselves, enjoying the bone afterward.
Grilling the lemon – Grilling the lemon cut side down is a simple yet delicious trick. It loosens and warms the lemon juice, infusing it with a subtle smokey flavor that enhances the steak. Plus, it adds a visually appealing garnish to your plate!
