This salmon gratin with broccoli and mushrooms is a healthy, nutritious, weeknight meal that your family will love!
Gratin is a French dish… originally. But strangely enough, it’s really popular in Japan!
So Japan does this thing where… they take things from other countries and then go crazy with it. Liiiiike have you ever had Japanese crepes? Oh baby. And how about cars? Any type of electronic device? Yeah, Japan is all about taking things from other countries and making it better.
You might not think gratin, which is basically any dish that has either a cheese or breadcrumb (or both) topping that gets browned in the oven, would be very Japanese. But, it’s just one of those things that took off, and now it’s a typical weeknight meal.
I thought it was a popular dish in America, since I grew up eating it, but turns out it’s actually not so common. My husband had never heard of it before, which made me realize… I had eaten it because my Japanese mother made it as a Japanese dish, not an American one.
Weird. I mean, doesn’t it just seem so… American? A white sauce, cheese, bread… a lot of times it’ll have potatoes or pasta in it… It seems so American! Well, I guess we DO eat scalloped potatoes a lot here. But there just isn’t the variation that you see in Japan.
The recipe I’m sharing with you is a healthy salmon gratin, with lots of vitamins and nutrients! It’s packed with salmon, mushrooms, broccoli, and onion! If broccoli and mushrooms aren’t your thing, you can substitute other veggies in there. Just make sure you cook or steam them first. The oven stage is just to melt the cheese and brown the top.
This gratin is easy to prepare, and SUCH a comfort food. Not to mention, if you make it in the individual dishes, it’s kind of a fun presentation. Of course, if you don’t have individual gratin dishes, you can make it in a bigger dish and just scoop it onto a plate!

Notes
Nutrition
made it last night and it was fantastic. One question regarding the onion and flour, should the excess flour go in the pan with the sliced onions or should it be discarded? Sauce was amazing but a bit thick.
I made this tonight. It is baking to melt the cheese right now I used a broccoli blend. That’s all I had. I put it all in a casserole dish. It looks amazing! Thank you for this recipe. I will let you know the outcome !
Thank you for sharing, great tasting & super easy!
However, curious how this is a Japanese dish? Maybe I’m just used to Americanized Japanese food but I’ve never seen a seen a cheese smothered, baked entree on any Japanese menu…
Hi RC, thanks for the comment! Gratin is a really popular home dish in Japan! Japan loves to take foreign dishes and make them their own, and gratin is a great example of that. So you won’t be seeing it on any American Japanese restaurant menus, but you would definitely find it on the menu in Japanese homes and restaurants!
Hi! Can I use oat milk instead?
I’m not familiar with cooking with oat milk, but if it can be substituted for milk with baking and other cooking applications, I’m assuming it would be fine!
Oh this is so delicious! I cut off some corn off of a couple of cons and added that with some diced cooked red potatoes. Will definitely make this again!
Thanks LaDawn, glad you liked it! The corn and red potatoes sound like great additions!
Was very easy to follow. And turned out delicious, definitely will make again.
Thank you! Glad you liked it!
Could you add potato’s? Would you have to fully cook them first?
Hi Mary Jo, each ingredient (broccoli, salmon, mushrooms) is sauteed or steamed before it goes into the gratin dishes, so I would do the same if you are adding potatoes! We are putting it in the oven to melt the cheese and meld everything together, so it wouldn’t be long enough to cook the potato at all. Hope that helps!
What does the measurement T represent please ( English ) thank you .
T is tablespoon and t is teaspoon ?
