The Perfect Porterhouse Steak & Marinade

I can still remember the smoky aroma that would fill my grandparents’ backyard every summer. My grandfather, a man of few words but immense culinary talent when it came to the grill, always had a perfectly cooked porterhouse waiting for us. He’d stand proudly, tongs in hand, his face flushed with heat and satisfaction. That memory, that taste of juicy, flavorful steak, is what I aim to recreate every time I fire up my own grill. This recipe, inspired by his unwavering dedication to simple, delicious food, is my tribute to those unforgettable summer evenings.

Recipe Overview

• Prep Time: 5 minutes
• Cook Time: 10-20 minutes (depending on thickness and desired doneness)
• Total Time: 8 hours 5 minutes (includes marinating time)
• Servings: 2
• Dietary Type: Not specified

Ingredients

• 2 (1 lb) porterhouse steaks
• ½ cup canola oil
• ¼ cup red wine vinegar
• ½ cup onion, chopped
• 1 tablespoon Worcestershire sauce
• 1 teaspoon salt
• 1 garlic clove, chopped or crushed

Equipment Needed

• Grill or broiler
• Dish or 1-gallon sized storage bag

Instructions

1. In a medium bowl, whisk together the canola oil and red wine vinegar until well blended. This emulsion is the foundation of our flavor profile.
2. Add the remaining ingredients – the chopped onion, Worcestershire sauce, salt, and chopped or crushed garlic – to the oil and vinegar mixture. Whisk again to combine, ensuring the salt is dissolved. The aroma at this stage should be tantalizing!
3. Place the porterhouse steaks in a dish or a 1-gallon sized storage bag. Pour the marinade over the steaks, ensuring they are evenly coated. If using a dish, turn the steaks to coat both sides. If using a bag, press out any excess air and seal tightly.
4. Marinate the steaks in the refrigerator for at least 8 hours. This allows the flavors to penetrate the meat, resulting in a more tender and flavorful final product. For optimal results, marinate overnight.
5. When ready to cook, remove the steaks from the refrigerator and let them sit at room temperature for about 30 minutes. This helps the steaks cook more evenly.
6. Preheat your grill to medium-high heat or preheat your broiler.
7. Remove the steaks from the marinade, letting any excess drip off. Discard the used marinade.
8. Grill or broil the steaks to your desired level of doneness. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C). For medium, aim for 135-145°F (57-63°C). Cooking times will vary depending on the thickness of the steaks and the heat of your grill or broiler.
9. Use a meat thermometer to check the internal temperature. Insert the thermometer into the thickest part of the steak, avoiding any bone.
10. Once the steaks reach your desired temperature, remove them from the grill or broiler and let them rest for at least 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Tent loosely with foil while resting.
11. Slice the steaks against the grain and serve immediately.

Expert Tips & Tricks

• Don’t skip the marinating time! It’s crucial for tenderizing and flavoring the steak. The longer the marinating time (up to 24 hours), the better.
• For an even deeper flavor, add a pinch of smoked paprika or a dash of hot sauce to the marinade.
• Before grilling, pat the steaks dry with paper towels. This will help them develop a beautiful sear.
• Use a high-quality meat thermometer to ensure accurate doneness.
• If you don’t have a grill, a cast-iron skillet is a great alternative for achieving a good sear.
• For a restaurant-worthy presentation, top the sliced steak with a pat of herb butter or a sprinkle of fresh herbs like parsley or chives.
• To check for doneness without a thermometer, use the “hand test.” Press the fleshy area at the base of your thumb. When relaxed, it feels like rare meat; when you touch your thumb to your index finger, it feels like medium-rare; thumb to middle finger is medium; thumb to ring finger is medium-well; thumb to pinky is well-done.

Serving & Storage Suggestions

Serve the porterhouse steak hot off the grill, sliced against the grain for maximum tenderness. It pairs wonderfully with classic sides like mashed potatoes, grilled asparagus, or a simple green salad.

Leftover steak should be stored in an airtight container in the refrigerator. It will last for 3-4 days. To reheat, gently warm the steak in a skillet over low heat or in a microwave, being careful not to overcook it. Leftover steak is also delicious sliced and added to salads, sandwiches, or tacos. It can also be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use this marinade for other types of steak?
A: Absolutely! This marinade works well with various cuts of steak, including ribeye, New York strip, and flank steak. Adjust cooking times accordingly based on the thickness of the cut.

Q: How long can I marinate the steak?
A: While a minimum of 8 hours is recommended, you can marinate the steak for up to 24 hours for optimal flavor and tenderness. Avoid marinating for longer than 24 hours, as the acid in the marinade can start to break down the meat too much.
