What Makes a Tomahawk Steak So Special?

If you’re not already obsessed with the tomahawk cut, it’s time to get acquainted. This bone-in ribeye steak is thick, dramatic, and loaded with intramuscular fat that melts into the meat during cooking. The long, Frenched bone adds theater to the presentation, while the rich marbling guarantees a juicy, tender bite every time.

Paired with a high-heat sear and a low-and-slow BBQ technique, this steak is crispy on the outside, blush-pink in the center, and dripping with flavor.

Ingredients You’ll Need

Here’s everything required to craft this steak-and-sauce masterpiece. Keep in mind: quality ingredients make a difference, especially when you’re working with just a few.

For the Garlic-Herb Steak Butter Rub:

  • 200g unsalted butter, softened
  • 4 garlic cloves, minced
  • 1 sprig fresh rosemary, finely chopped
  • 1 tbsp steak seasoning rub (preferably smoky/spicy)
  • 1 dash olive oil
  • Freshly ground black pepper, to taste
  • Sea salt, to taste

For the Chimichurri Sauce:

  • ½ cup olive oil
  • 3 tbsp red wine vinegar
  • 3 cloves garlic, minced
  • 1 small red onion, finely chopped
  • 1 red chili pepper, deseeded and finely minced (adjust for spice preference)
  • 1 handful fresh parsley, chopped
  • 1 handful fresh basil, chopped
  • 1 tsp dried oregano
  • 1 small handful fresh cilantro, chopped
  • Salt and pepper, to taste

How to Grill a Tomahawk Steak to Perfection

1. Start with Room-Temperature Meat

Let the tomahawk sit at room temperature for 30–60 minutes before cooking. This helps it cook more evenly and promotes a better crust.

2. Make the Garlic Herb Butter Rub

In a bowl, combine the softened butter, garlic, rosemary, steak rub, olive oil, pepper, and salt. Mix until creamy and well-blended. This compound butter will act as a flavor-packed marinade and base rub.

3. Coat the Steak Generously

Massage the butter mixture all over the steak—don’t be shy. Get it into every crevice. Then cover and refrigerate for at least 30 minutes (or up to overnight for maximum infusion).

Indirect BBQ Grilling: Low and Slow Is Key

This technique creates a juicy steak without overcooking the exterior.

  • Set up your grill for indirect heat at 110°C (230°F)
  • Place the tomahawk on the cool side of the grill, away from direct flame
  • Close the lid and let the steak cook slowly until it reaches an internal temperature of 47°C (116°F)
  • This can take 45–60 minutes depending on the thickness

Finish with a High-Heat Reverse Sear

Once the tomahawk hits 47°C internally, it’s time to crank up the heat:

  • Move the steak to the hot zone of the grill
  • Sear for 1–2 minutes per side until a dark crust forms
  • Pull the steak off the grill when it hits 51°C (124°F) internally for medium-rare
  • Immediately wrap it loosely in aluminum foil and rest for 5–10 minutes
    • This lets the juices redistribute, ensuring a tender result

While the Steak Rests: Make Your Chimichurri

This vibrant Argentinian-inspired sauce comes together fast:

  1. Combine the olive oil, vinegar, minced garlic, chopped red onion, and chili in a bowl
  2. Add chopped parsley, basil, oregano, and cilantro
  3. Stir well, season with salt and pepper, and let sit for 10 minutes to meld flavors
  4. Taste and adjust acidity, salt, or spice to your liking

The result? A bold, herbaceous sauce that’s equal parts fresh and fiery, and it cuts beautifully through the richness of the steak.

Slicing and Serving Your Tomahawk Steak

Use a sharp carving knife to slice the steak against the grain into thick, juicy slices. Arrange them on a platter and drizzle the chimichurri over the top or serve it on the side.

Pair it with:

  • Grilled vegetables
  • Roasted potatoes
  • Corn on the cob
  • A crisp arugula salad with lemon vinaigrette

Tips for Tomahawk Steak Success

  • Use a meat thermometer: Don’t guess. With thick cuts, internal temperature is the only way to nail the doneness.
  • Let it rest: Skipping the rest period will cause juices to leak when slicing.
  • Play with heat: For gas grills, use a 2-zone setup. For charcoal, push coals to one side.
  • Herbs matter: Fresh herbs in the butter and chimichurri make a noticeable difference. Avoid dried substitutes for parsley or basil.

Why You’ll Make This Again (And Again)
