What Ingredients You Will Need

This grilled porterhouse steak recipe uses simple, wholesome ingredients that bring out rich, bold flavors without any fuss. The chimichurri sauce highlights fresh herbs and a touch of acidity that complements the steak perfectly. Most of these ingredients are pantry staples, and the fresh parsley and cilantro can be swapped for what you have on hand.

• For the Porterhouse Steak:
  • 1 large porterhouse steak (about 24 oz / 680 g), well-marbled and at room temperature
  • 2 tablespoons olive oil (for brushing)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 teaspoon garlic powder (optional, adds a subtle depth)
• For the Fresh Chimichurri Sauce:
  • 1 cup fresh parsley leaves, packed (roughly 30 g)
  • 1/2 cup fresh cilantro leaves, packed (roughly 15 g) — you can skip if you’re not a cilantro fan
  • 4 cloves garlic, minced
  • 1 small shallot, finely chopped (adds a mild sweetness)
  • 1/3 cup red wine vinegar (80 ml)
  • 1/2 cup extra virgin olive oil (120 ml) — I recommend Colavita for the smoothest flavor
  • 1 teaspoon crushed red pepper flakes (adjust to taste)
  • 1 teaspoon kosher salt
  • Freshly ground black pepper, to taste
  • Juice of half a lemon (brightens the sauce)

Pro tip: If fresh herbs are scarce, frozen parsley can work in a pinch, but fresh is definitely better for that vibrant punch. For a twist, try swapping red wine vinegar with apple cider vinegar for a fruitier note.

Equipment Needed

• Grill (gas or charcoal) — charcoal adds a smoky flavor, but gas works fine too
• Long-handled tongs for flipping the steak
• Sharp chef’s knife and cutting board for prepping herbs and steak
• Mixing bowl for the chimichurri sauce
• Food processor or blender (optional) to quickly combine chimichurri ingredients, though chopping by hand works if you prefer more texture)
• Instant-read meat thermometer (highly recommended to get the perfect doneness)
• Basting brush for oiling the steak
• Aluminum foil to tent the steak after grilling

I’ve tried making chimichurri by hand and with a blender — both work, but the blender gives a smoother sauce that clings better to the steak. If you don’t own a meat thermometer, you can still grill successfully by feel, but I always trust a quick temp check for consistent results.

Preparation Method

1. Bring the Steak to Room Temperature: Remove the porterhouse steak from the fridge about 30 minutes before grilling to let it come to room temperature. This helps it cook evenly and reduces grill time.
2. Season the Steak: Brush both sides of the steak lightly with olive oil. Generously season with kosher salt, black pepper, and garlic powder (if using). Let it rest while you prepare the chimichurri.
3. Make the Chimichurri Sauce: In a bowl or food processor, combine parsley, cilantro, garlic, shallot, red wine vinegar, olive oil, red pepper flakes, salt, pepper, and lemon juice. Pulse or stir until well combined but still slightly chunky. Taste and adjust seasoning — this sauce should be bright, tangy, and a little spicy. Set aside to allow flavors to meld.
4. Preheat the Grill: Get your grill hot — around 450-500°F (230-260°C). For charcoal, wait until coals are covered in white ash. Clean and oil the grates to prevent sticking.
5. Grill the Porterhouse Steak: Place the steak directly over the hottest part of the grill. Grill for about 4-5 minutes per side for medium-rare (internal temp of 130-135°F / 54-57°C). Adjust time if your steak is thicker or thinner. Use tongs to flip — don’t poke the meat with a fork!
6. Check Doneness: Use an instant-read thermometer to check the internal temperature. For medium, aim for 140-145°F (60-63°C). Remember, the steak will continue cooking slightly while resting.
7. Rest the Steak: Transfer the steak to a cutting board and tent loosely with foil. Rest for 10 minutes to let juices redistribute. This step is key for tender, juicy bites.
8. Slice and Serve: Slice the steak against the grain, and spoon fresh chimichurri sauce generously over the top. Serve immediately.

Quick tip: If flare-ups happen from dripping fat, move the steak to a cooler part of the grill to avoid charring. And don’t forget — resting is your friend! It really makes a difference in juiciness.

Cooking Tips & Techniques

Grilling a porterhouse steak can feel intimidating, but a few tricks make it straightforward and stress-free. First, always let the steak come to room temperature before grilling. Cold meat on a hot grill can cook unevenly and stay tough.

Using a meat thermometer changed my grilling game — no more guessing. For a perfect medium-rare, pull the steak off the heat at about 130°F (54°C) and let it rest to finish cooking. This prevents that dreaded overcooked edge.

When making chimichurri, don’t skimp on freshness. The herbs, garlic, and vinegar are what give the sauce its punch. I learned the hard way that dried herbs just won’t do. Also, letting the sauce sit for at least 10 minutes before serving helps the flavors marry beautifully.

One common mistake is crowding the grill. Give your steak room for air circulation and crust formation. And avoid flipping repeatedly — one flip per side is enough.

Last but not least, pay attention to the grill heat. Too hot, and you risk burning the outside while leaving the inside undercooked. Too low, and you won’t get that crave-worthy sear. Patience and practice go a long way here.

Variations & Adaptations

• Herb Swaps: If you’re not a fan of cilantro, double up on parsley or add fresh oregano for a slightly different herbaceous note in your chimichurri.
• Spice Level: Add more crushed red pepper flakes or a dash of smoked paprika for a smoky heat twist.
• Cooking Method: Don’t have a grill? No worries — you can pan-sear the porterhouse steak in a cast-iron skillet over high heat, then finish in a 400°F (200°C) oven until desired doneness.
• Dietary Adjustments: For a lower-fat option, trim some of the fat from the steak edges, and use less olive oil in the chimichurri. The flavor stays vibrant without weighing you down.
• Personal Twist: I once tried adding finely chopped green olives and a splash of sherry vinegar to the chimichurri — it gave a briny depth that was surprisingly addictive.

Serving & Storage Suggestions

This grilled porterhouse steak with fresh chimichurri sauce is best served right off the grill for that juicy, tender experience. I like to plate it with simple sides like grilled asparagus or a light salad — something like the fresh southwest chipotle salad balances the richness beautifully.

If you need to store leftovers, wrap the steak tightly in foil and refrigerate for up to 3 days. Store chimichurri sauce separately in an airtight container. When reheating, gently warm the steak slices in a skillet over low heat to keep them tender, and drizzle fresh chimichurri on top before serving.

Interestingly, the flavors of the chimichurri deepen after a day in the fridge, making it a great make-ahead sauce for grilling nights. Just bring it back to room temperature before serving to unlock that fresh brightness again.
