Grilled Porterhouse Steak With Cilantro Lime Compound Butter

The first time I truly understood the power of a perfectly cooked steak was at a small family barbecue. My grandfather, a man of few words but immense culinary wisdom, grilled a porterhouse that was the stuff of legends. The sear was impeccable, the inside a rosy medium-rare, and the simple seasoning of salt and pepper allowed the beef’s inherent richness to shine. It was a revelation, a primal experience that sparked a lifelong love affair with grilling. While Grandpa Joe kept his methods simple, this recipe elevates the experience with a vibrant cilantro-lime compound butter – a finishing touch that adds a bright, herbaceous counterpoint to the savory steak, creating a symphony of flavors that dance on the palate.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 5-10 minutes
• Total Time: 30 minutes
• Servings: 4
• Dietary Type: Gluten-Free

Ingredients

For the Steak:

• 4 porterhouse steaks (about 1/2-inch thick)
• Salt, to taste
• Freshly ground black pepper, to taste
• Canola oil, for brushing

For the Compound Butter:

• 1/2 cup (4 ounces) plus 2 tablespoons (1 ounce) unsalted butter, softened
• 2 tablespoons finely chopped cilantro
• 1/2 lime, juice and zest
• 1 garlic clove, finely chopped
• 1 tablespoon Worcestershire sauce
• Salt and freshly ground black pepper, to taste

Equipment Needed

• Small sauté pan
• Medium bowl
• Fork
• Plastic wrap
• Indoor grill pan or outdoor grill

Instructions

1. Begin by preparing the compound butter. In a small sauté pan over medium heat, melt the 2 tablespoons of butter. Add the finely chopped garlic and cook for about 1 minute, or until the garlic is fragrant, being careful not to burn it.
2. Transfer the garlic butter to a medium bowl. Add the lime juice, lime zest, and Worcestershire sauce. Whisk to combine thoroughly.
3. Use a fork to blend in the remaining 1/2 cup (1 stick) of softened butter until the mixture is smooth and well combined. Season with salt and freshly ground black pepper to taste. Fold in the finely chopped cilantro. Mix until evenly distributed.
4. On a sheet of plastic wrap, shape the compound butter into a cylinder (like a log). Twist the ends of the plastic wrap to seal, and refrigerate for at least 1 hour to allow the butter to firm up. If you need it sooner, you can place it in the freezer for a faster chilling process.
5. About 20 minutes before grilling, remove the porterhouse steaks from the refrigerator. Rinse them under cold water and pat them completely dry with paper towels.
6. Brush both sides of the steaks with canola oil, ensuring even coverage. Generously season both sides with salt and freshly ground black pepper to taste.
7. Cover the steaks loosely and let them sit at room temperature for 10 to 15 minutes, allowing the seasoning to penetrate the meat and the steaks to relax slightly.
8. Preheat your indoor grill pan or outdoor grill to high heat. It’s crucial to let the grill get extremely hot to achieve a good sear.
9. Carefully place the steaks on the preheated grill. Cook for 3 minutes on the first side, then flip and cook for an additional 2 minutes on the second side for medium-rare doneness. Note: Cooking time will vary depending on the thickness of the steaks and your desired level of doneness. If using an indoor grill pan, cook one steak at a time to ensure even cooking and proper searing.
10. Transfer the grilled steaks to a platter. Immediately top each steak with a slice of the cilantro-lime compound butter.
11. Cover the platter loosely with aluminum foil and let the steaks rest for 10 minutes before serving. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful steak.
12. Serve immediately and enjoy!

Expert Tips & Tricks

• Achieving the Perfect Sear: A screaming hot grill is essential for a good sear. Don’t be afraid to let it get really hot.
• Doneness Matters: Use a meat thermometer to ensure your steak reaches your desired level of doneness. Medium-rare is around 130-135°F, medium is 135-145°F, and medium-well is 145-155°F.
• Resting is Key: Never skip the resting period. It allows the juices to redistribute, resulting in a more tender and flavorful steak.
• Compound Butter Flavor Boost: Feel free to experiment with other herbs in the compound butter, such as parsley, chives, or thyme. A pinch of red pepper flakes can add a little heat.
• Garlic Infusion: Cooking the garlic in butter first infuses the butter with a subtle garlic flavor without the harshness of raw garlic. Be careful not to burn the garlic.
• Thin Cut Doneness: For thinner steaks like these, be extra vigilant about cooking time; they cook faster and can easily become overdone. Keep a close eye and use a thermometer for the most accurate results.

Serving & Storage Suggestions

Serve the grilled porterhouse steaks immediately, topped with a generous slice of the cilantro-lime compound butter. The butter will melt slightly over the hot steak, creating a delicious sauce.

Leftover steak can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium-low heat or in a low-temperature oven (250°F) to prevent overcooking. You can also slice the cold steak thinly and add it to salads or sandwiches.

The cilantro-lime compound butter can be stored in the refrigerator for up to 1 week or in the freezer for up to 3 months. If frozen, thaw it in the refrigerator before using.

Variations & Substitutions

• Spicy Steak: Add a pinch of red pepper flakes to the steak seasoning or the compound butter for a little heat.
• Lemon-Herb Butter: Substitute lemon juice and zest for the lime, and use a mix of parsley, oregano, and thyme for the herbs.
• Garlic Herb Butter: Increase the amount of garlic and add other herbs such as rosemary and thyme.
• Dairy-Free Butter: Use a plant-based butter alternative to make the compound butter dairy-free. Look for high-quality vegan butters with a good fat content for the best flavor and texture.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of steak for this recipe?

A: Absolutely! While porterhouse is a great choice, you can also use ribeye, New York strip, or even sirloin. Adjust the cooking time accordingly based on the thickness of the steak.

Q: How do I know when the steak is cooked to my desired doneness?

A: The most accurate way is to use a meat thermometer. Insert it into the thickest part of the steak, avoiding bone. Reference the temperature ranges mentioned in the “Expert Tips” section.

Q: Can I make the compound butter ahead of time?

A: Yes, in fact, it’s recommended! The compound butter can be made several days in advance and stored in the refrigerator or frozen for longer storage.

Q: What if I don’t have a grill?

A: You can cook the steak in a cast-iron skillet on the stovetop. Heat the skillet until it’s smoking hot, then sear the steak on both sides until cooked to your desired doneness.

Q: Can I use dried herbs instead of fresh cilantro in the compound butter?

A: While fresh herbs are always preferred for their vibrant flavor, you can use dried cilantro in a pinch. Use about 1 teaspoon of dried cilantro for every 2 tablespoons of fresh cilantro.
