Tuna Steaks With Orange and Rosemary

The scent of rosemary always transports me back to my grandmother’s garden in Tuscany. She had an enormous rosemary bush, practically a small tree, that she used in everything from roasting lamb to infusing olive oil. One sweltering summer, I remember grilling tuna steaks with her, the air thick with the perfume of rosemary and citrus. The bright, herbaceous notes of the rosemary perfectly complemented the richness of the tuna, while the orange added a vibrant zest that danced on the palate. It was a simple meal, shared under the Tuscan sun, but it left an indelible mark on my culinary soul.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 6-8 minutes
• Total Time: Approximately 23 minutes
• Servings: 6
• Dietary Type: Pescatarian, Gluten-Free, Dairy-Free

Ingredients

• 2 lbs tuna steaks
• 2 oranges
• 4 garlic cloves, chopped
• 6 sprigs rosemary, chopped
• 1/2 teaspoon coarse salt
• 1 teaspoon ground black pepper
• 3 tablespoons balsamic vinegar
• 1/4 cup extra virgin olive oil
• 3 green onions, sliced

Equipment Needed

• Cutting board
• Knife
• Zester
• Mixing bowl
• Grill pan (or outdoor grill)
• Tongs

Instructions

1. Begin by preparing the tuna steaks. Cut the tuna steaks into 6 equal portions, ensuring each piece is roughly the same thickness for even cooking.

2. Next, prepare the oranges. Zest both oranges, being careful to only remove the colorful outer layer and avoid the bitter white pith. After zesting, slice the oranges into thin rounds. Reserve a few slices for garnish if desired.

3. In a mixing bowl, combine the orange zest with the chopped garlic, chopped rosemary, salt, pepper, balsamic vinegar, and extra virgin olive oil. This mixture will form the flavorful marinade for the tuna.

4. Add the tuna portions to the bowl and coat them evenly with the orange-rosemary dressing. Ensure each steak is well covered to maximize the flavor infusion.

5. Let the tuna steaks stand in the marinade for 15 minutes at room temperature. This allows the flavors to penetrate the fish. Do not marinate for longer than 30 minutes, as the acidity of the balsamic vinegar can begin to “cook” the tuna, altering its texture.

6. While the tuna is marinating, preheat a grill pan over medium-high heat. If using an outdoor grill, ensure it is clean and properly heated. A hot grill is crucial for achieving a good sear on the tuna.

7. Once the grill pan is hot, carefully place the marinated tuna steaks on the grill. Cook for 3 to 4 minutes on each side, depending on the thickness of the tuna and your desired level of doneness. For medium-rare, the internal temperature should reach approximately 125-130°F (52-54°C). Use a meat thermometer to ensure accurate cooking.

8. Remove the tuna steaks from the grill pan and transfer them to a serving platter.

9. Top the tuna steaks with the sliced green onions and garnish with the reserved orange slices. This adds a fresh, vibrant touch to the presentation.

Expert Tips & Tricks

• Choosing Tuna: Look for tuna steaks that are bright red or pink in color, with a firm texture and a fresh, sea-like smell. Avoid tuna that looks dull or smells fishy.
• Doneness: Be careful not to overcook the tuna, as it can become dry and tough. Tuna steaks are best served medium-rare to medium, with a slightly pink center.
• Flavor Boost: For an extra layer of flavor, add a pinch of red pepper flakes to the marinade. This will provide a subtle kick of heat that complements the citrus and herbs.
• Herb Variations: While rosemary is the star of this dish, you can experiment with other herbs such as thyme or oregano.
• Deglazing: After removing the tuna from the grill pan, deglaze the pan with a splash of white wine or chicken broth. This will create a flavorful sauce that can be drizzled over the tuna.

Serving & Storage Suggestions

Serve the Tuna Steaks with Orange and Rosemary immediately after grilling for the best flavor and texture. This dish pairs well with a side of grilled vegetables, a simple salad, or couscous. A crisp white wine, such as a Sauvignon Blanc or Pinot Grigio, complements the flavors of the tuna and citrus.

Leftover tuna should be stored in an airtight container in the refrigerator. It will keep for up to 2 days. Reheat gently in a skillet over low heat or enjoy cold in a salad. Note that reheated tuna may be slightly drier than freshly grilled tuna. It is not recommended to freeze cooked tuna, as it can significantly alter the texture.

Variations & Substitutions

• Citrus Variations: Experiment with other citrus fruits such as grapefruit or blood oranges for a unique twist on the flavor profile.
• Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce to the marinade for a spicy kick.
• Herb Alternatives: If you don’t have rosemary on hand, try using fresh thyme, oregano, or even a combination of Italian herbs.
• Gluten-Free Option: Ensure that the balsamic vinegar you use is gluten-free if you have dietary restrictions. Most balsamic vinegars are naturally gluten-free, but it’s always a good idea to check the label.
• Marinade Swap: For a richer marinade, substitute honey for the balsamic vinegar.

FAQs (Frequently Asked Questions)

Q: Can I use dried rosemary instead of fresh?
A: While fresh rosemary is preferred for its more vibrant flavor, you can use dried rosemary. Use about 2 teaspoons of dried rosemary for every 6 sprigs of fresh rosemary.

Q: How do I prevent the tuna from sticking to the grill pan?
A: Make sure your grill pan is very hot before adding the tuna, and lightly oil the pan with a high-smoke-point oil like avocado or grapeseed oil. Also, avoid moving the tuna around too much while it’s cooking.

Q: Can I marinate the tuna overnight?
A: It’s best not to marinate tuna for longer than 30 minutes, as the acid in the balsamic vinegar can start to break down the fish and make it mushy.

Q: What is the best way to tell if the tuna is cooked to medium-rare?
A: The best way is to use a meat thermometer. Insert it into the thickest part of the tuna. Medium-rare is around 125-130°F (52-54°C). The tuna should also be slightly firm to the touch but still have some give.

Q: Can I bake the tuna instead of grilling it?
A: Yes, you can bake the tuna. Preheat your oven to 400°F (200°C) and bake the tuna for 8-10 minutes, or until it reaches your desired level of doneness.
