Pepper-Crusted Tuna Steak with Parsley-Garlic Butter

The first time I tasted tuna prepared this way, I was skeptical. My grandfather, a man of simple tastes, declared it a delicacy. He’d slather the steak with an absurd amount of freshly cracked black pepper, enough to make my eyes water just from the aroma. The char from the grill, the fiery pepper, and that bright, herby butter—it was a symphony of flavors I hadn’t expected. Now, every summer, I fire up the grill and remember him, carefully adjusting the pepper level for those with less adventurous palates, but always making sure there’s enough for me.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 8-10 minutes
• Total Time: 20 minutes
• Servings: 4
• Dietary Type: Pescatarian, Gluten-Free

Ingredients

• 2 tablespoons kosher salt
• 1 cup freshly cracked black pepper
• 4 (8 ounce) tuna steaks, at least 1 inch thick
• 2 tablespoons olive oil

For the Butter:

• ½ cup unsalted butter, softened
• 1 teaspoon minced garlic
• 2 tablespoons fresh lemon juice (about ½ lemon)
• ¼ cup roughly chopped fresh parsley

Equipment Needed

• Small bowl
• Grill

Instructions

1. Make the Butter: In a small bowl, thoroughly combine the softened butter, minced garlic, fresh lemon juice, and chopped fresh parsley. Mix until well incorporated and uniform in color.

2. Refrigerate the Butter: Cover the bowl with plastic wrap or transfer the butter mixture to an airtight container. Refrigerate the butter to allow the flavors to meld and the butter to firm up slightly. This will make it easier to handle and serve.

3. Prepare the Pepper Crust: In another small bowl, combine the kosher salt and freshly cracked black pepper. Mix thoroughly to create an even seasoning blend.

4. Coat the Tuna Steaks: Gently press the tuna steaks into the salt and pepper mixture, ensuring that all sides are thoroughly coated with the seasoning. Don’t be shy—you want a good crust of pepper on each steak.

5. Drizzle with Olive Oil: Lightly drizzle the coated tuna steaks with olive oil. This will help the pepper adhere and create a nice sear on the grill.

6. Prepare the Grill: Preheat your grill to a medium-hot temperature. You should be able to hold your hand about 5 inches above the grates for only 5-6 seconds. Clean the grill grates thoroughly to prevent sticking.

7. Grill the Tuna: Place the tuna steaks on the preheated grill. Grill for 4-5 minutes per side for medium-rare, depending on the thickness of the steaks. For a medium cook, grill for an additional 1-2 minutes per side.

8. Check for Doneness: The internal temperature for medium-rare tuna is around 125-130°F (52-54°C). You can use a meat thermometer to check. The tuna should still be slightly pink in the center. Overcooked tuna will be dry and less flavorful.

9. Serve: Remove the tuna steaks from the grill and let them rest for a minute or two. Top each steak with a generous spoonful of the prepared parsley-garlic butter. The butter will melt slightly from the heat of the tuna, creating a delicious sauce. Serve immediately.

Expert Tips & Tricks

• Freshness is Key: Use the freshest tuna you can find. The quality of the tuna will greatly impact the final flavor of the dish. Look for steaks that are bright red and have a fresh, sea-like smell.
• Adjust the Pepper: If you’re not a fan of intense pepper flavor, reduce the amount of freshly cracked black pepper to ½ cup or even less. You can always add more pepper at the table if desired.
• Don’t Overcook: Tuna is best served medium-rare to medium. Overcooking will result in a dry, tough steak.
• Make Ahead: The parsley-garlic butter can be made up to 3 days in advance and stored in the refrigerator. This allows the flavors to meld and makes for easier preparation on the day you plan to grill the tuna.
• Even Cooking: Ensure that your grill is evenly heated to promote consistent cooking across the entire steak.
• Resting Period: Allowing the tuna to rest for a few minutes after grilling allows the juices to redistribute, resulting in a more tender and flavorful steak.

Serving & Storage Suggestions

Serve the pepper-crusted tuna steak immediately after grilling for the best flavor and texture. It pairs well with grilled vegetables like asparagus, zucchini, or bell peppers. A simple side salad with a lemon vinaigrette also complements the richness of the tuna and butter.

Leftover tuna can be stored in an airtight container in the refrigerator for up to 2 days. It’s best enjoyed cold in salads or sandwiches, as reheating can dry it out. The parsley-garlic butter can be stored separately in the refrigerator for up to a week. You can also freeze the butter for longer storage, up to 2 months. Wrap it tightly in plastic wrap and then place it in a freezer bag.

Reheating is not generally recommended, but if you must, do it gently in a skillet over low heat, adding a little butter or oil to prevent sticking. Avoid microwaving, as it can make the tuna tough and rubbery.

FAQs (Frequently Asked Questions)

Q: Can I use pre-ground black pepper instead of freshly cracked?
A: While you can, freshly cracked black pepper provides a much more robust and aromatic flavor. The pre-ground pepper tends to lose its potency quickly.

Q: How do I know when the tuna is cooked to medium-rare?
A: Use a meat thermometer! Insert it into the thickest part of the steak. Medium-rare is around 125-130°F (52-54°C). The tuna should also feel slightly firm to the touch.

Q: Can I grill the tuna indoors using a grill pan?
A: Absolutely! A grill pan can be a great alternative when outdoor grilling isn’t possible. Make sure the pan is very hot before adding the tuna to get a good sear.

Q: What’s the best way to store the parsley-garlic butter?
A: Store it in an airtight container in the refrigerator. It will keep for up to a week. For longer storage, freeze it in small portions.

Q: Can I use a different type of fish for this recipe?
A: Yes, this recipe also works well with other firm-fleshed fish like swordfish or marlin. Adjust the grilling time as needed, depending on the thickness of the fish.
