Perfect Grilled Porterhouse Recipe with Easy Blue Cheese Butter

“You gotta try the blue cheese butter with that porterhouse,” my buddy muttered as I fumbled with my grill tongs, eyes squinting against the smoke. I was skeptical — blue cheese on steak? That sounded like a fancy restaurant move, not my usual backyard BBQ tactic. But honestly, after that first bite of the perfect grilled porterhouse with blue cheese compound butter, I was hooked.

It all started on a hectic Friday evening when the grill was practically calling my name after a long week.

But throwing on a dollop of homemade blue cheese butter changed the game; it melted gently over the meat, adding a tangy richness that balanced the charred crust perfectly. Since then, I’ve made this recipe more times than I can count—sometimes twice in one week!

If you love a steak that’s got character, a bit of boldness, and a comforting richness, this recipe will become your go-to for special dinners or even those “just because” moments.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and the blue cheese component can be swapped depending on your preference or availability.

• For the Porterhouse Steak:
• 1 large porterhouse steak, about 1.5 to 2 inches thick (roughly 20 oz / 570 g)
• Salt, preferably kosher or sea salt (key for crust formation)
• Freshly ground black pepper
• Olive oil or avocado oil for brushing (helps with searing)
• For the Blue Cheese Compound Butter:
• 4 tablespoons unsalted butter, softened (I like Plugrá for its creaminess)
• 2 ounces blue cheese, crumbled (Roquefort or Gorgonzola work beautifully)
• 1 small clove garlic, finely minced (adds a subtle kick)
• 1 teaspoon fresh thyme leaves, chopped (or ½ teaspoon dried thyme)
• Freshly ground black pepper, to taste
• Optional: a few drops of lemon juice (to brighten flavors)

Ingredient Tips: Look for a firm, crumbly blue cheese rather than overly creamy varieties to keep the butter texture just right. If you prefer a milder cheese, try substituting with a blue cheese blend or even blue cheese dressing for a shortcut. For a dairy-free twist, swap butter with a vegan butter alternative and omit the cheese or use a plant-based blue cheese substitute.

Season your porterhouse liberally; thick cuts appreciate a generous salt crust to bring out their natural flavor. For a splash of freshness, sprinkle a little chopped parsley on the finished dish.

Equipment Needed

• Outdoor grill or grill pan (cast iron preferred for consistent heat)
• Instant-read meat thermometer (crucial for perfect doneness)
• Mixing bowl (to blend the compound butter ingredients)
• Small spatula or fork (for mixing butter)
• Aluminum foil (to rest the steak after grilling)
• Sharp chef’s knife (for trimming and slicing)

If you don’t have a grill, a heavy-bottomed cast iron skillet works well. When using a grill pan, preheat it for at least 5 minutes to get a good sear. I personally prefer the aroma and char from an open flame grill, but the pan method is a solid backup. For making the butter, a simple mixing bowl and fork get the job done—no fancy gadgets needed.

Preparation Method

1. Prepare the Compound Butter (10 minutes): In a small bowl, combine the softened unsalted butter, crumbled blue cheese, minced garlic, chopped thyme, and a pinch of black pepper. Mix well until it forms a creamy, evenly blended compound butter. Optionally, add a few drops of lemon juice to brighten the flavor. Shape the butter into a log using plastic wrap and refrigerate while you prep the steak.
2. Prep the Steak (5 minutes): Take the porterhouse out of the fridge about 30 minutes before cooking to bring it to room temperature (if you plan ahead). Pat it dry with paper towels—this helps develop a great crust. Brush both sides lightly with olive oil, then season generously with salt and freshly ground black pepper. Don’t be shy with the seasoning; thick cuts need it.
3. Preheat the Grill: Light your grill for direct high heat—aim for about 450–500°F (230–260°C). If you’re using a grill pan, place it over medium-high heat until smoking hot.
4. Grill the Porterhouse (8–10 minutes per side): Place the steak on the grill and cook for 8–10 minutes on the first side without moving it. Flip carefully with tongs and grill the other side for another 8–10 minutes for medium-rare (internal temperature around 130–135°F / 54–57°C). Use an instant-read thermometer to check doneness—this is key to avoid overcooking.
5. Rest the Steak (10 minutes): Transfer the steak to a plate and tent loosely with foil. Let it rest for 10 minutes; this redistributes the juices and keeps the steak juicy.
6. Serve with Blue Cheese Butter: Slice the butter into medallions and place on top of the steak while it’s resting or just before serving. The butter will melt slowly, seeping into the meat’s crevices and adding richness.

Pro Tip: If your butter is too cold, slice thin medallions and let them soften slightly before topping the steak. The contrast of the cold butter melting over hot steak is part of the charm.

Be mindful of flare-ups on the grill; keep a spray bottle of water handy to tame flames without ruining that coveted crust. Also, resist the urge to poke or prod the steak too much—it’ll keep the juices locked in.

Cooking Tips & Techniques

The perfect grilled porterhouse is all about heat control and timing. Here are some tips I’ve picked up along the way:

• Room Temperature Meat: Letting your steak sit out for 30 minutes before grilling helps it cook evenly. Cold meat on a hot grill can result in an overcooked exterior and underdone interior.
• Don’t Overflip: Flip the steak just once or twice. Constant flipping can prevent that beautiful crust from forming.
• Use a Meat Thermometer: Guesswork is overrated. An instant-read thermometer is the best way to nail your preferred doneness.
• Resting Is Critical: Never skip resting. Cutting into steak immediately after grilling causes all the juices to spill out, leaving dry meat.
• Compound Butter Consistency: Whip the butter until fluffy for easy spreading and melting. If the butter is too cold, it won’t melt nicely on the steak.

One time, I left the steak on the grill a bit too long and ended up with a chewy crust. Lesson learned: timing really matters. Also, letting the butter soften at room temp before using it makes a big difference. I’ve found multitasking during grilling—prepping sides or setting the table—helps keep the process smooth without rushing the steak.

Variations & Adaptations

Looking to switch things up? Here are some tasty ways to tweak the recipe:

• Herb Variations: Swap thyme for rosemary or oregano in the compound butter for a different aroma.
• Dietary Adjustments: Use a dairy-free butter and skip the blue cheese or replace it with a vegan cheese option to make it plant-based friendly.
• Spicy Kick: Add a pinch of cayenne pepper or smoked paprika to the compound butter for subtle heat.
• Cooking Methods: If you don’t have a grill, try pan-searing the porterhouse in a cast iron skillet and finish in a hot oven at 400°F (200°C) for 5–7 minutes.
• Seasonal Twist: During summer, serve with grilled corn and a fresh tomato salad to balance the richness.

Personally, I once tried incorporating a bit of horseradish into the butter for a sharp tang that cut through the richness beautifully. It’s worth experimenting to find your perfect flavor combo.

Serving & Storage Suggestions

This grilled porterhouse is best served hot, straight off the grill with butter melting luxuriously over the top. Present it on a warm platter to keep the steak cozy. Garnish with extra fresh thyme or parsley for color and aroma.

It pairs wonderfully with simple sides like roasted asparagus, garlic mashed potatoes, or even a crisp Caesar salad. For drinks, a robust red wine like Cabernet Sauvignon or a smoky bourbon cocktail complements the bold flavors perfectly.

To store leftovers, wrap the steak tightly in foil or place in an airtight container and refrigerate for up to 3 days. The compound butter can be refrigerated separately and sliced as needed. Reheat gently in a skillet over medium-low heat or in a 300°F (150°C) oven until warmed through to keep the steak tender.

Flavors actually deepen when the steak rests overnight, so making it a day ahead for a meal is a smart move if you want to prep in advance.
