How to Make Japanese Unagi (Grilled Eel)
Prepare Tare Sauce: In a small saucepan, combine soy sauce, mirin, sake, sugar, and water. Simmer over medium heat for about 10 minutes, until the sugar dissolves and the sauce thickens slightly, achieving a glaze-like consistency.
Grill Prep: Preheat your charcoal grill or grill pan to medium-high heat. Lightly brush the surface with vegetable oil to prevent the eel from sticking during cooking.
Steam Eel: Place your cleaned and deboned unagi fillets in a bamboo steamer. Steam them for 5-7 minutes to soften the flesh and reduce excess oil, ensuring they’re tender and ready to grill.
First Grill: Carefully lay the steamed eel skin-side down on the hot grill. Grill for about 5-6 minutes, or until it develops a lovely golden-brown color and slight crispness on the outside.
Baste and Flip: Brush the grilled side with tare sauce, then carefully flip the eel over. Grill for another 3-4 minutes. Continue basting with tare sauce and flipping until cooked through, which should take around 15-20 minutes total.
Serve: Once done, allow the eel to rest for a few moments before slicing it diagonally. Serve it over bowls of warm steamed rice, drizzling extra tare sauce on top and sprinkling with sansho pepper for a zesty finish.
Optional: Garnish with fresh herbs or sesame seeds for an added touch of flavor.

Expert Tips for Japanese Unagi
Quality Matters: Always select fresh, high-quality unagi for the best flavor and texture; frozen options may lack the same richness.
Brushing Technique: Brush the tare sauce on gently during grilling to avoid burning; a light coat keeps the glaze vibrant and flavorful.
Heat Control: Maintain a steady medium-high heat on the grill; too hot can char the eel while not cooking it properly.
Steam Well: Steaming the eel before grilling ensures tenderness; do not skip this step or it may turn out too tough.
Resting Time: Allow the grilled eel to rest a few minutes before slicing; this enhances moisture retention, making each bite even juicier.
Cooking Time: Pay attention to cooking times, as overcooking can lead to dry eel. Keep a close eye and adjust based on thickness.

Japanese Unagi (Grilled Eel) Recipe FAQs
How do I select the best Unagi for grilling?
Absolutely! When selecting Unagi, look for firm, glistening fillets without any discoloration. Fresh eel should smell clean, reminiscent of the sea, and not fishy. Dark spots all over indicate older fish, so skip those! If possible, source from a reputable fishmonger who specializes in Asian seafood for the best quality.
What s the best way to store leftover Unagi?
I recommend storing leftover Japanese Unagi in an airtight container in the refrigerator for up to 3 days. Before sealing, ensure the eel is completely cooled to maintain freshness and avoid condensation, which can lead to sogginess. For longer storage, wrap the eel tightly in plastic wrap and place it in a freezer bag, where it will stay good for up to 3 months!
Can I freeze Unagi and how do I do it?
Very! To freeze Japanese Unagi, first wrap the cooled eel tightly in plastic wrap to prevent freezer burn. Then, place it in a labeled freezer bag, removing any excess air. When ready to enjoy, thaw it in the fridge overnight. To reheat, steam or gently microwave the eel on low power, which will keep it moist and tender just avoid frying or high heat, which can dry it out.
How can I prevent my Unagi from sticking to the grill?
To avoid sticking, make sure to preheat your grill properly and lightly oil the surface before grilling. I often use sesame oil for added flavor, which also helps. Additionally, brushing a light coat of tare sauce on the eel can create a protective layer that minimizes sticking. Use a sharp-edged spatula to gently lift the eel if needed, rather than trying to pull it off with tongs.
Are there any dietary considerations for serving Unagi?
Definitely! Japanese Unagi contains a good amount of protein and is considered a delicacy. However, those with seafood allergies should avoid it, as it may trigger reactions similar to other fish. If serving to pets, make sure to keep the grilled eel out of reach, as the rich sauces and ingredients like garlic can be harmful to them. Always check the ingredients for any specific dietary restrictions.
Can I use a different cooking method for Unagi?
Absolutely! If grilling isn t an option for you, consider broiling or even pan-searing the eel. Simply follow your preferred method, ensuring you still steam the Unagi first to retain tenderness. For broiling, place in an oven-safe dish, baste with tare sauce, and broil on high for 5-6 minutes while keeping a close eye to avoid burning. Enjoy the lovely smoky flavor that comes from different techniques!
