I started making this on a Tuesday when I had leftover rice, a salmon fillet I needed to use up, and basically no desire to stand over a stove. It came together in about 35 minutes total, and my roommate immediately asked for the recipe. That’s usually how I know something’s a keeper.
The idea is simple: seasoned sushi-style rice goes into a small baking dish, the miso-glazed salmon sits right on top, and the whole thing roasts in the toaster oven until the fish is flaky and the glaze is slightly caramelized at the edges. The rice on the bottom gets a little more steam than crisp, which honestly makes it more comforting than a straight roasted salmon fillet would be on its own. If you want crispier rice edges, press it closer to the sides of the pan and let it bake a minute or two longer before adding the salmon.
For this recipe, you really want something with a dedicated bake setting and a broil function. A good toaster oven with a broil setting makes the difference between glazed and just cooked — the high heat at the end is what turns the miso coating dark and sticky in the best possible way. I’d also suggest having a proper small toaster oven baking dish on hand rather than improvising with foil — it holds the rice layer better and cleans up in about two minutes.
One thing I’ll say about the miso glaze: don’t rush it. If you can let the salmon sit with the glaze on it for even 10 minutes before it goes in the oven, the flavor gets noticeably deeper. It’s not mandatory, just worth knowing.
Toaster Oven Crispy Miso-Glazed Salmon Onigiri Bake with Sesame and Scallions
Seasoned sushi rice packed into a baking dish, topped with miso-glazed salmon, and run under the toaster oven broiler until golden and slightly caramelized. It's a weeknight dinner that feels like you actually tried.

Instructions
Prep the Rice and Glaze
-
Preheat your toaster oven to 400°F on the bake setting. Lightly brush or rub a small baking dish (an 8x8 works, or whatever fits your toaster oven) with neutral oil.
-
Stir together the rice vinegar, sugar, and salt in a small bowl until dissolved. Fold into your warm cooked rice along with 1 tablespoon sesame seeds and half the sliced scallions. Don't overmix — just a few gentle folds so the rice stays fluffy and doesn't turn gluey.
-
Press the seasoned rice into an even layer in your oiled baking dish. It doesn't need to be perfect. Packed but not smashed is the goal.
-
Whisk together the miso, soy sauce, honey, rice vinegar, sesame oil, and ginger in a small bowl until smooth. Taste it — it should be salty, a little sweet, and pretty punchy. That's exactly what you want.
Roast the Salmon
-
Pat the salmon portions dry with paper towels. Place them skin-side down directly on top of the rice layer. Spoon or brush the miso glaze generously over the top and sides of each piece. Use all of it — there's no saving it for later.
-
Bake at 400°F for 16 to 18 minutes, depending on thickness. The salmon is done when it flakes easily with a fork in the thickest part. If you like a slightly more caramelized, sticky top, switch to broil for the last 2 minutes and keep a close eye on it. Toaster oven broilers can go from golden to burnt fast.
-
Pull it out and let it sit for 2 minutes before serving. Scatter the remaining scallions and a pinch of sesame seeds over the top. Lay a few strips of nori across each piece if you're using it — I think it's worth doing.
Notes
Day-old rice genuinely works better here — freshly cooked rice can be a little wet and steams rather than crisping under the salmon. If all you have is fresh rice, spread it on a sheet pan for 10 minutes before using it to let some steam escape. White miso is milder and sweeter than red miso. Red will work but the glaze gets more intense and a bit saltier, so taste before you add the full amount of soy sauce. You can swap the salmon for an equal weight of firm tofu (pressed and sliced thick) for a fully pareve version — roast time will be similar, maybe slightly longer. Leftovers keep well in the fridge for up to 2 days. Reheat in the toaster oven at 350°F for about 8 minutes rather than microwaving, which makes the rice gummy.
