How to Cook Frozen Unagi

I know what you’re thinking – “Frozen eel? Isn’t that going to be all mushy and gross?” Well, my friend, let me tell you, with the right technique, you can transform that frozen unagi into a crispy, caramelized masterpiece that’ll have your taste buds doing a little happy dance. Trust me, I’ve been there, done that, and I’m here to share all my hard-earned wisdom.

Thawing the Frozen Unagi

The first step in your frozen unagi journey is proper thawing. Do not, I repeat, do not just leave that package out on the counter all day. That’s a surefire way to end up with a stinky, mushy mess. Instead, take the time to thaw it gently in the fridge. Depending on the size of the package, this can take anywhere from 5 to 6 hours, but it’s worth the wait.

Once it’s fully thawed, you’ll want to pat the unagi dry with some paper towels. This will help ensure that crispy, caramelized exterior we’re going for.

Preparing the Unagi Sauce (Tare)

Now, let’s talk about the all-important unagi sauce, or “tare” as it’s known in Japan. This sweet and savory elixir is the key to taking your frozen unagi to the next level. Here’s how to make it:

Ingredients:

  • 1/2 cup soy sauce
  • 1/2 cup mirin (Japanese sweet rice wine)
  • 3 tablespoons sugar

In a small saucepan, combine the soy sauce, mirin, and sugar. Bring the mixture to a simmer over medium heat, stirring occasionally, until the sugar has dissolved and the sauce has thickened slightly, about 4-5 minutes. Be careful not to let it boil too vigorously, or the sauce can become too thick.

Once the sauce is ready, remove it from the heat and let it cool slightly. This tare is going to be the star of the show, so make sure to have it on hand before you start cooking the unagi.

Broiling the Unagi

Alright, time to get that frozen eel sizzling! Preheat your oven’s broiler to high heat and line a baking sheet with foil. Place the unagi fillets on the prepared baking sheet, making sure they’re not overlapping.

Broil the unagi for 3-4 minutes per side, keeping a close eye on it. You want that skin to get nice and crispy, with a beautiful caramelized sheen. Once the first side is done, flip the fillets over and broil the other side for another 3-4 minutes.

Pro Tip: Baste the unagi with the tare sauce during the last minute or two of broiling to really amp up the flavor and get that signature sticky-sweet glaze.

Serving the Unagi Donburi

Now that your unagi is perfectly cooked, it’s time to assemble the ultimate Japanese rice bowl, the unagi donburi. Here’s what you’ll need:

Ingredients:

  • Cooked white rice
  • Broiled unagi fillets
  • Tare sauce
  • Optional toppings: Fried egg, sliced green onions, toasted sesame seeds

To serve, simply place a generous portion of steamed white rice in a bowl. Top with the broiled unagi fillets, drizzle with the tare sauce, and add any desired toppings. The runny yolk of a fried egg pairs beautifully with the rich, caramelized eel, while the green onions and sesame seeds add a lovely crunch and nutty flavor.

Pro Tip: If you’re feeling extra fancy, you can also serve the unagi donburi with a side of pickled ginger or a crisp, refreshing salad to balance out the richness of the dish.

Storing and Reheating Leftovers

One of the best things about using frozen unagi is that you can keep a stash in your freezer for up to 3 months, making it easy to satisfy those cravings whenever they strike. When you’re ready to enjoy it again, simply repeat the thawing and broiling process.

As for leftovers, you can store any extra unagi donburi in an airtight container in the fridge for up to 3 days. To reheat, simply pop it in the microwave for 1-2 minutes, or until heated through. You can also reheat the unagi fillets separately in the broiler for a minute or two to help restore that crispy texture.

Variations and Substitutions

Now, while I’m a purist when it comes to unagi donburi, I know that some of you out there might want to get a little creative. Here are a few ideas to mix things up:

  • Unagi Sushi: Slice the broiled unagi fillets into thin strips and use them as a topping for your favorite sushi rolls or nigiri.
  • Unagi Onigiri: Stuff triangles of warm, fluffy rice with the broiled unagi and tare sauce for a portable, on-the-go snack.
  • Unagi Yakisoba: Stir-fry the unagi with soba noodles, vegetables, and the tare sauce for a delicious twist on a Japanese classic.
  • Unagi Tacos: Shred the broiled unagi and serve it in warm corn tortillas with your choice of toppings, like shredded cabbage, diced avocado, and a drizzle of tare sauce.

The possibilities are endless, my friends! So don’t be afraid to get a little creative and put your own spin on this beloved Japanese dish.
