Seafood okonomiyaki is one of Japan’s most beloved street foods, a savory pancake that’s crispy on the outside, tender on the inside, and loaded with flavor in every bite. While okonomiyaki is endlessly customizable, the seafood version is especially popular for its umami-rich taste and satisfying texture. If you’ve never tried it before, imagine a cross between a pancake, an omelet, and a seafood fritter, all topped with flavorful sauces and garnishes.
The base of the dish starts with a simple batter made from flour, water (or dashi broth), eggs, and shredded cabbage. The cabbage gives the pancake structure and a slight crunch, while the batter becomes golden and crispy when cooked. To this base, a medley of seafood is added, usually shrimp, squid, scallops, or a combination of all three. These cook right in the batter, releasing their briny juices and giving the dish a rich, ocean-forward flavor.
Cooking seafood okonomiyaki is easy and fun. The batter is ladled onto a hot griddle or nonstick skillet and shaped into a thick round pancake. As it cooks, the seafood gently steams inside while the exterior develops a crisp, golden crust. Once it’s flipped and cooked through, the pancake is ready for toppings, and that’s where the real magic happens.
A classic seafood okonomiyaki is topped with a generous drizzle of okonomiyaki sauce (similar to a thick Worcestershire sauce), Japanese mayo, a handful of bonito flakes (which seem to dance from the heat), and a sprinkle of dried seaweed flakes or chopped green onions. Pickled ginger or a touch of spicy mustard can also be added for a little extra zing.
This dish is satisfying, comforting, and endlessly adaptable. You can swap in your favorite seafood, make mini versions for appetizers, or even try it with a gluten-free flour blend. Whether you’re craving something cozy and filling or want to impress your friends with a Japanese-inspired meal, seafood okonomiyaki is a flavorful choice that’s as fun to make as it is to eat.

I didn’t have dashi stock, so used chicken broth. Still turned out pretty yummy! You gotta be creative, right? 😉
I didn’t have okonomiyaki sauce so I used Worcestershire + ketchup (don’t judge). It tasted good, but it wasn’t the same. Also my aonori was clumpy, so yeah visually not perfect.
Honestly? That sounds like a totally legit hack. Worcestershire + ketchup is pretty close in vibe—more tangy/savory than people expect. Not identical, but if it tasted good, that’s the win.
I don’t have dashi stock, so I used chicken broth… it was okay, but I think I lost the “real” flavor. Still tasty though.
Not bad, but my batter felt too thick? I added a splash more dashi and it got better. Also I used larger shrimp and they took longer to cook through.
Okonomiyaki with seafood? Sounds weird but actually tasted decent! I was surprised.
Ehh, was a bit bland… needs more seasonings or something. Not bad.
I dunno about this okonomiyaki… What even is dashi stock? Sounds fishy.
Delicious and authentic-ish. I love that you get 4 pancakes from this—perfect for sharing. The only tweak I’d do is season the batter slightly (salt/pepper) because dashi brands vary.
Interesting take! I actually skip salt/pepper because the okonomiyaki sauce + bonito flakes already bring flavor. But yeah, dashi brands vary so it could help if your stock is weaker.
Totally agree on the seasoning—my dashi was super light the first time, so the batter ended up a bit bland. A pinch of salt made a big difference for me. Also love that you mentioned 4 pancakes for sharing—perfect amount!
Yum!! I love how customizable this is. Added some cheese!
Cheese?! That sounds kinda weird for okonomiyaki. But hey, if you like it, go for it! 🤷♂️
lol i messed up the flipping. my first one broke into pieces but tasted good anyway. i ate it with chopsticks so technically successful 😅
I didn’t have aonori seaweed flakes so I just used extra green onion. It tasted good but it was missing that ocean-y vibe. Could be an ingredient thing.
Bonito flakes on top at the end is such a vibe—watching them “dance” is so satisfying.
I don’t understand how it’s a pancake if it’s not sweet?? Makes no sense to me. 🤔
This was amazing! I love the seafood flavor in the okonomiyaki. Will make it again!
Glad you liked it! I also add some cheese sometimes for extra flavor!
I’m skeptical about the bonito flakes being “raw” on top, but they do melt a bit with the heat. Flavor is real—smoky and salty. Would definitely make again if I find squid at a good price.
I had no idea what dashi was, but this turned out pretty good. Might try it again!
Yum! But I didn’t have squid so I added some bacon instead. Still delicious!
I mean, is bacon even gonna taste the same? Squid’s kinda salty, but bacon’s sweet, right? Idk if that’s gonna work, but hey, whatever floats your boat.
Bacon? In okonomiyaki? That’s a twist! I would have never thought of that, but I bet it adds a nice flavor! Gonna try this next time!
I tried something similar once and it came out a bit soggy, but the dashi in the batter here seems like it would help a lot. Going to attempt!
I made this for my family and they actually liked it!! Big win for me. Will be making again!
I dunno, I’m not a fan of seafood in pancakes. Seems kinda weird to me. But glad it worked for you!
That’s awesome! It’s always a relief when they actually enjoy what you make. What did they like the most about it?
This looks dangerously good. I love anything with okonomiyaki sauce + mayo combo—must be insanely savory with the squid and shrimp.
Not gonna lie, I’m skeptical the batter will crisp evenly—4-5 minutes a side feels short. Also do you cook the squid fully or does it stay chewy? Still sounds tasty though.
Right?? The okonomiyaki sauce + mayo combo is pure savory magic. With squid and shrimp too, this sounds dangerously good 😍
Didn’t have bonito flakes but used bacon instead = fantastic!
I made this and my dog loved it too 😂! Not sure what that says about my cooking, lol.
This was way better than I expected—crisp edges and the dashi really makes it taste “authentic.” I used frozen shrimp and it still worked great.
Not sure about 1/4 cup flour to 1 cup dashi—mine came out too runny. Next time I’ll adjust with a bit more flour or reduce the liquid.
Yeah, that ratio can be tricky—dashi brand and how you measure flour (scooped vs leveled) really changes the batter. I start by adding the dashi a little at a time until it looks like thick pancake batter.
Very complicated! I mean, dashi stock? What’s that? Just use water lol.
Are bonito flakes really necessary? I omitted them and it still tasted okay but idk.
What’s with dashi stock? Can’t I just use water? Sounds strange to me.
It was okay, but I expected more flavor. Maybe I added not enuff dashi?
Meh. Too many toppings for me and the dashi flavor felt kinda fishy. I’d rather keep it simpler.
Totally get that. When there are too many toppings it can drown out the pancake itself—keeping the dashi more noticeable sounds way better.
Interesting—mine always tastes like “sea” but not “fishy” if the dashi is decent. Maybe your dashi stock was old or too strong? I’d try a lighter dashi next time and use fewer toppings, like just sauce + bonito.
Was too hard to flip it, I need a bigger spatula next time.
