What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or fresh herbs, making this an easy recipe to pull together any time.

• For the Porterhouse Steak:
  • 1 porterhouse steak, about 1.5 to 2 inches thick (approximately 24 oz or 680 g)
  • 2 tablespoons olive oil (for brushing)
  • 1 teaspoon kosher salt (preferably Maldon or Diamond Crystal for best texture)
  • 1/2 teaspoon freshly ground black pepper
  • Optional: 1/2 teaspoon smoked paprika (adds subtle smokiness)
• For the Zesty Chimichurri Sauce:
  • 1 cup fresh flat-leaf parsley, packed and roughly chopped
  • 1/4 cup fresh oregano leaves (or 1 tablespoon dried oregano)
  • 3-4 garlic cloves, minced (adjust based on your love for garlic)
  • 1/3 cup extra virgin olive oil (use a fruity one like California Olive Ranch)
  • 2 tablespoons red wine vinegar (adds that essential tang)
  • 1 teaspoon crushed red pepper flakes (optional, for a kick)
  • Salt and freshly ground black pepper to taste
  • Juice of half a lemon (for brightness and balance)

Pro tip: If fresh oregano is hard to find, Italian seasoning can work in a pinch, but fresh herbs really make a difference here. For a gluten-free version, all ingredients are naturally safe as is. I like to buy my porterhouse from a trusted butcher who trims it well but leaves the bone intact—that’s where much of the flavor comes from when grilling. The olive oil and vinegar combo in the chimichurri is crucial for that zesty punch, so don’t skimp on quality for those.

Equipment Needed

• Outdoor grill (charcoal preferred for smoky flavor, but gas works great too)
• Long-handled tongs (to flip the steak safely)
• Sharp chef’s knife (for slicing the steak and chopping herbs)
• Mixing bowl (to combine chimichurri ingredients)
• Meat thermometer (optional but helpful for precise cooking)
• Wooden spoon or whisk (to stir chimichurri)
• Cutting board (preferably wooden or plastic, for carving)

If you don’t have access to an outdoor grill, a grill pan on the stove can work, though the smoky char won’t be quite the same. I’ve also found that using a cast iron skillet indoors can get a nice crust, but watch for smoke! For those on a budget, tongs and a reliable knife are the essentials—you can skip the thermometer if you’re comfortable with visual doneness cues. A mortar and pestle for the chimichurri garlic is a nice touch but not necessary if you’re short on tools.

Preparation Method

1. Prep the Steak: Take the porterhouse out of the fridge about 30 minutes before cooking to bring it to room temperature. This helps with even cooking. Pat it dry with paper towels, then brush both sides lightly with olive oil.
2. Season: Generously sprinkle kosher salt and black pepper on both sides, pressing the seasoning gently into the meat. Add smoked paprika if using. Let it rest while you prepare the chimichurri (about 10 minutes).
3. Make the Chimichurri: In a bowl, combine chopped parsley, oregano, minced garlic, red pepper flakes, and red wine vinegar. Slowly whisk in olive oil until emulsified. Add lemon juice, salt, and pepper to taste. Set aside at room temperature to let the flavors mingle.
4. Preheat the Grill: Get your grill hot—aim for about 450°F (232°C). For charcoal grills, wait until coals are covered with white ash. For gas grills, preheat on high with the lid closed for 10-15 minutes.
5. Grill the Steak: Place the porterhouse on the hottest part of the grill. Cook for 4-5 minutes without moving it to develop a good sear. Flip and grill the other side for another 4-5 minutes for medium-rare (internal temp around 130°F / 54°C). Adjust time if your steak is thicker or if you prefer more done.
6. Check for Doneness: Use a meat thermometer if you have one, or do the finger test for firmness. Remember, the steak will continue to cook a bit after resting.
7. Rest the Steak: Transfer the steak to a cutting board and tent loosely with foil. Let it rest for about 10 minutes to redistribute juices.
8. Slice and Serve: Cut the steak off the bone, then slice across the grain into thick strips. Spoon generous amounts of the zesty chimichurri over each serving.

Quick tip: Don’t poke the steak with a fork while grilling—that lets precious juices escape. Also, if flare-ups happen, move the steak to a cooler part of the grill for a bit. The chimichurri can be made a day ahead and refrigerated; just bring it back to room temperature before serving to let those flavors pop.

Cooking Tips & Techniques

Grilling a porterhouse can feel intimidating, but here’s what I’ve learned after a few too many overcooked steaks. First, patience is key. You want a good sear on the outside, so resist the urge to flip the steak repeatedly—one flip per side is enough. Keeping the grill hot means you get those mouthwatering grill marks and a slight char that adds complexity.

Another thing: thickness matters. This recipe works best with a steak at least 1.5 inches thick. Thinner cuts cook too fast and can dry out. If you don’t have a thermometer, press the steak gently with your finger—medium-rare should feel like the fleshy part of your palm below your thumb when your hand is relaxed.

For the chimichurri, fresh herbs really make the difference. I’ve tried dried herbs in a pinch, but it just isn’t the same vibrant zing. Also, don’t be shy with the garlic and vinegar; they give the sauce its signature punch. If you like a little heat, crushed red pepper flakes add a nice touch without overpowering.

Finally, multitasking is your friend. While the steak is resting, finish up the chimichurri and get your sides ready. I love pairing this meal with creamy sides like creamy parmesan creamed spinach for some extra indulgence.

Variations & Adaptations

This recipe is pretty versatile, so feel free to tweak it to your liking or dietary needs.

• Herb Variations: Swap parsley and oregano for cilantro and mint for a different chimichurri vibe—bright and a little sweeter.
• Spicy Twist: Add a finely chopped fresh jalapeño or a dash of smoked chipotle powder to the chimichurri for more heat.
• Different Cuts: If porterhouse feels too large or pricey, try ribeye or New York strip steaks—the chimichurri pairs just as well.
• Cooking Method: For indoor cooking, use a hot cast iron skillet or broil the steak in the oven, finishing with chimichurri drizzled on top.
• Allergen-Friendly: This recipe is naturally gluten-free and dairy-free, perfect for many dietary restrictions.

One variation I love is subbing in smoked paprika and a splash of balsamic vinegar in the chimichurri for a richer, deeper flavor. It’s a twist I first tried when making butter chicken and thought, why not on steak too?

Serving & Storage Suggestions

Serve your grilled porterhouse steak with zesty chimichurri warm, right off the grill, for that perfect contrast of juicy meat and fresh sauce. A sprinkling of flaky sea salt on top just before serving brings out the flavors even more.

This steak pairs wonderfully with simple sides like grilled vegetables, roasted potatoes, or a crisp salad. If you want to keep things indulgent, creamy mashed potatoes or the classic roasted garlic mashed potatoes are always winners.

Store any leftovers in an airtight container in the fridge for up to 3 days. The chimichurri’s fresh herbs may mellow, but the sauce still adds a nice zing. Reheat steak gently in a warm oven or skillet to avoid drying it out. Sometimes, I thinly slice the cold leftover steak for sandwiches or toss it into a quick stir-fry for a no-fuss second meal.

Nutritional Information & Benefits

This grilled porterhouse steak with chimichurri offers a hearty, protein-rich meal that’s also packed with vibrant herbs and healthy fats. A 6-ounce (170 g) serving of porterhouse steak provides about 45 grams of protein and essential nutrients like iron and zinc, which are great for energy and immune health.

The chimichurri sauce adds antioxidants and vitamins from fresh parsley and oregano, plus heart-healthy monounsaturated fats from olive oil. This recipe is naturally low in carbs and free from gluten and dairy, making it suitable for many diets.

Frequently Asked Questions

How do I know when my porterhouse steak is done?

Use a meat thermometer for best results: 130°F (54°C) for medium-rare, 140°F (60°C) for medium. If you don’t have one, gently press the steak—medium-rare feels like the fleshy part of your palm beneath the thumb when relaxed.

What if I don’t have a grill? Can I cook this steak indoors?

Yes, a cast iron skillet on high heat or broiling in the oven works well. Just aim for a good sear and watch carefully to avoid overcooking.

Is porterhouse steak expensive? Are there cheaper alternatives?

Porterhouse can be pricier, but ribeye or New York strip steaks can be substituted with similar results, especially when paired with chimichurri.

Can I adjust the chimichurri for less garlic or heat?
