For a delicious and zesty Garlic Herb Tuna Steak Marinade, combine freshly minced garlic with a medley of fragrant herbs such as parsley, basil, and thyme. Add a splash of zesty lemon juice and a drizzle of olive oil to create a vibrant mixture that infuses the tuna with tantalising flavours. Season with salt and freshly cracked black pepper to taste. Allow the tuna steaks to marinate for at least 30 minutes, letting the aromatic herbs soak into the fish, enhancing its natural richness. When ready to cook, grill or pan-sear the steaks to perfection, turning them into a culinary delight that pairs beautifully with a crisp salad or roasted vegetables. The result is a succulent dish that's as pleasing to the palate as it is to the eye.
