Ingredients
This recipe makes 2 servings.
For the Tuna Steaks
- 2 (6 oz / 170g each) fresh tuna steaks, about 1-inch thick
- 1/4 cup white sesame seeds
- 1/4 cup black sesame seeds (optional, for visual appeal)
- 1 tablespoon olive oil or avocado oil, plus more for searing
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Keto Sesame Sauce
- 2 tablespoons tamari or coconut aminos (gluten-free, soy-free alternative)
- 1 tablespoon rice vinegar (check for no added sugar, or use apple cider vinegar)
- 1 teaspoon toasted sesame oil
- 1/2 teaspoon grated fresh ginger
- 1/4 teaspoon garlic powder (or 1/2 clove fresh minced garlic)
- Pinch of red pepper flakes (optional, for a little kick)
For Garnish (Optional)
- Sliced green onions
- Extra sesame seeds
Step-by-Step Instructions
-
Step 1: Prepare the Tuna Steaks
Pat the tuna steaks very dry with paper towels. This helps the sesame seeds stick better and ensures a good sear. Season both sides of the tuna steaks with salt and black pepper.
Small tip: Dry tuna is key for a crispy crust. Don’t skip this step!
-
Step 2: Coat the Tuna with Sesame Seeds
On a shallow plate, combine the white and black sesame seeds. Gently press each tuna steak into the sesame seed mixture, coating all sides evenly. Make sure to get a good layer of seeds on each steak.
Small tip: Use your hands to gently press the seeds onto the tuna if they aren’t sticking well.
-
Step 3: Prepare the Keto Sesame Sauce
In a small bowl, whisk together the tamari (or coconut aminos), rice vinegar, toasted sesame oil, grated ginger, garlic powder, and red pepper flakes (if using). Taste and adjust seasoning if needed. Set aside.
Small tip: Fresh ginger adds a wonderful zing. If you don’t have fresh, a pinch of ground ginger can work in a pinch.
-
Step 4: Heat the Pan
Heat a large non-stick skillet or cast-iron pan over medium-high heat. Add 1 tablespoon of olive oil or avocado oil to the hot pan. Let the oil get shimmery but not smoking.
Small tip: A hot pan is crucial for a good sear. If the pan isn’t hot enough, the tuna will steam instead of sear.
-
Step 5: Sear the Tuna Steaks
Carefully place the sesame-crusted tuna steaks into the hot pan. Sear for 1.5 to 2 minutes per side for rare to medium-rare, or 3-4 minutes per side for medium. The cooking time will depend on the thickness of your tuna and your preferred doneness.
Small tip: Tuna cooks very quickly! Keep an eye on it. It’s best served rare to medium-rare with a pink center.
-
Step 6: Rest and Slice
Once cooked to your liking, remove the tuna steaks from the pan and let them rest on a cutting board for 2-3 minutes. This allows the juices to redistribute, keeping the tuna moist. Slice the tuna against the grain into 1/2-inch thick slices.
Small tip: Resting meat is important for tenderness and flavor. Don’t cut it immediately after cooking.
-
Step 7: Serve and Garnish
Arrange the sliced tuna on plates. Drizzle generously with the prepared Keto Sesame Sauce. Garnish with sliced green onions and extra sesame seeds, if desired. Serve immediately and enjoy!
Small tip: A sprinkle of fresh cilantro or chopped chives can also add a lovely fresh touch!
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free if you use tamari or coconut aminos instead of traditional soy sauce. Always double-check your rice vinegar to ensure it’s gluten-free.
- Vegan/Vegetarian Option: For a delicious plant-based alternative, try this recipe with thick slices of firm tofu or tempeh. Press the tofu well to remove excess water, then coat and sear as you would the tuna.
- Add More Vegetables or Protein: Boost your meal by serving the tuna over a bed of sautéed spinach, steamed broccoli, cauliflower rice, or a crisp mixed green salad. You can also add more protein by serving it alongside some edamame (if tolerated on keto) or a poached egg.
- Spicy Version: For a fiery kick, increase the red pepper flakes in the sauce. You can also add a dash of your favorite keto-friendly hot sauce, or a pinch of cayenne pepper, to the sesame seed coating.
- Flavor Tip: Citrus Boost: A squeeze of fresh lime or lemon juice over the finished dish can brighten all the flavors. You can also add a tiny bit of citrus zest to the sauce for an extra aromatic touch.

Health Benefits
This Keto Sesame Tuna Steaks recipe isn’t just delicious; it’s packed with amazing health benefits!
Tuna is a fantastic source of lean protein, essential for muscle repair and growth, and keeping you feeling full and satisfied. It’s also rich in Omega-3 fatty acids, particularly EPA and DHA, which are crucial for heart health, brain function, and reducing inflammation throughout the body. These healthy fats are especially important on a ketogenic diet.
Sesame seeds, both white and black, contribute a wealth of nutrients. They are a good source of healthy fats, fiber, and plant-based protein. They also contain important minerals like calcium, magnesium, iron, and zinc. The lignans found in sesame seeds have antioxidant properties that can help protect your cells from damage.
Ginger and garlic, key ingredients in our savory sauce, are more than just flavor enhancers. Ginger is well-known for its anti-inflammatory and antioxidant effects, and it can aid digestion. Garlic has powerful immune-boosting properties and can contribute to cardiovascular health.
Finally, using healthy fats like olive oil or avocado oil for cooking adds monounsaturated fats, which are beneficial for heart health and can help with nutrient absorption. This dish truly is a powerhouse of nutrition!
Serving Suggestions
- Green Power: Serve these tuna steaks alongside a vibrant green salad tossed with a simple lemon-tahini dressing, or a side of steamed asparagus with a drizzle of olive oil.
- Cauliflower Rice Bowl: Create a delicious bowl by placing the sliced tuna over a bed of warm cauliflower rice, topped with avocado slices and a sprinkle of nori (seaweed) strips.
- Quick Lunch Prep: This dish is excellent for meal prep! Cook the tuna, slice it, and store it separately from the sauce. Reheat gently or enjoy cold over a fresh salad for a quick, healthy lunch.
Storage Tips
Leftover Keto Sesame Tuna Steaks can be stored in an airtight container in the refrigerator for up to 2-3 days. For best quality, it’s ideal to eat tuna fresh. While you can freeze cooked tuna, the texture might change slightly upon thawing, becoming a bit drier. If reheating, warm gently in a skillet over low heat for a few minutes until just heated through, or enjoy cold. Avoid overcooking when reheating to maintain tenderness.
