Ingredients for Tuna Teriyaki Kabobs

1-1/2 pounds tuna steaks, cut into 1-1/2-inch chunks
2 medium sweet red peppers, cut into 1-inch pieces
1 large sweet onion, cut into 1-inch pieces
1/4 cup minced fresh cilantro
1/4 cup sesame oil
3 tablespoons lime juice
2 tablespoons soy sauce
2 tablespoons extra virgin olive oil
1 tablespoon minced fresh gingerroot
2 garlic cloves, minced
1 package (5 ounces) fresh baby spinach
1 medium sweet yellow pepper, cut into 1-inch pieces
8 cherry tomatoes, halved

How to Make Tuna Teriyaki Kabobs

Thread the tuna chunks onto four metal or soaked wooden skewers. On four additional skewers, alternate threading the red peppers, yellow pepper, and onion pieces. Place the skewers in a shallow 13×9-inch baking dish.
In a medium bowl, whisk together the sesame oil, lime juice, soy sauce, olive oil, gingerroot, and garlic to create the marinade. Reserve half to use as salad dressing later, and pour the remaining half over the skewers. Cover and refrigerate for 30 minutes.
Preheat a greased grill to medium heat. Grill the vegetable kabobs first, turning them occasionally until they are crisp-tender (about 10-12 minutes). Add the tuna kabobs to the grill and cook for 2-3 minutes per side until the tuna is just slightly pink in the center for medium-rare. Move the tuna off direct heat to avoid overcooking while vegetables finish.
In a large mixing bowl, toss the spinach, cherry tomatoes, and reserved dressing. Serve the salad on plates, topped with one tuna kabob and one vegetable kabob for each portion.

Nut-Free: Use avocado oil in place of sesame oil if nut allergies are a concern.

Our Team’s Tips for the Best Tuna Teriyaki Kabobs

Soak wooden skewers in water for at least 30 minutes to prevent them from burning on the grill.
Cut tuna and vegetables into uniform sizes to ensure even cooking.
When grilling tuna, avoid overcooking—it’s best served medium-rare for tender, juicy results.
Make the marinade a day ahead for even deeper flavor.
Leftovers? Store kabobs in an airtight container in the fridge for up to 2 days. Reheat gently or enjoy cold over the salad.

Tuna Teriyaki Kabobs FAQs

Can I bake tuna teriyaki kabobs instead of grilling?

Yes! Preheat your oven to 425°F (220°C) and bake the skewers on a parchment-lined sheet for 10-12 minutes, turning halfway through.

How do I choose the freshest tuna for kabobs?

Look for tuna steaks that are firm, bright red, and have no fishy odor. Ask your fishmonger for sushi-grade tuna for best results.

What should I do if I don’t have a grill?

A stovetop grill pan works beautifully! Heat over medium-high and follow the same cooking times as the outdoor grill.

Can these kabobs be frozen?

We don’t recommend freezing the assembled kabobs. However, you can freeze the tuna chunks and make the dish fresh when needed.

Are these tuna teriyaki kabobs meal-prep friendly?

Absolutely! Prep the vegetables, marinade, and cut the tuna in advance. When it’s time to cook, thread the skewers and get them on the grill in minutes.
